Bedewy Research Group captures WCMNM Best Paper Award

Industrial

PITTSBURGH (September 30, 2019) ... The Bedewy Research Group has won the Best Paper Award at the 019 World Congress on Micro and Nano Manufacturing (WCMNM), where Mostafa Bedewy, PhD presented research results from his NanoProduct Lab on Tuesday September 10, 2019 in Raleigh, North Carolina. PhD student Moataz Abdulhafez is first author for the paper “In Situ Measurement of Carbon Nanotube Growth Kinetics in a Rapid Thermal Chemical Vapor Deposition Reactor with Multizone Infrared Heating," and former postdoc Jaegeun Lee is second author. Dr. Bedewy is an Assistant Professor of Industrial Engineering, Chemical & Petroleum Engineering (secondary appointment), and Mechanical Engineering & Materials Science (secondary appointment). He joined the Swanson School of Engineering in September 2016. In this work, Dr. Bedewy’s team introduced a unique experimental capability for carbon nanotube growth by chemical vapor deposition, based on a custom-designed multizone rapid thermal processing reactor with real-time monitoring of growth kinetics using videography and image processing. Combining these measurements with 3D optical microscopy, electron microscopy, Raman spectroscopy, and density measurements enable unprecedented study of the time-varying collective growth stages, and the resulting dynamics of nanotube population behavior. “We like to watch these forests of nanotubes grow,” commented Dr. Bedewy. “As billions of these tiny ‘hairs’ grow and interact together on an area smaller than a penny, they build a macroscopic stricture of vertically aligned nanotubes, which has very interesting mechanical, thermal, and electrical properties. A major challenge however is to control the spatial variation of their properties, which we uniquely achieve based on our custom-designed reactor.” This work was funded by the National Science Foundation (NSF) under award #1825772, titled “Functionally Graded Carbon Nanotubes by Dynamic Control of Morphology during Chemical Vapor Deposition.” This conference, which was hosted at North Carolina State University, was Jointly organized by The 4M Association, The International Institution for Micro Manufacturing (I2M2), and The International Forum on Micro Manufacturing (IFMM). According to WCMNM, the Congress hopes to bring together the worldwide community of micro and nano manufacturing experts. ###

Manipulating the Meta-Atom

Industrial

PITTSBURGH (September 19, 2019) … Metamaterials are a unique class of intricate composites engineered to interact with electromagnetic radiation – such as light – in ways that go beyond conventional materials. By designing their structure at the nanometer scale, such materials can steer, scatter and rotate the polarization of the light in unusual ways. Realizing their full potential in sectors like consumer electronics, bioimaging or defense, requires the ability to manipulate their intricate structure. This presents a daunting challenge – how to manipulate the nanoscale meta-atoms making up metamaterials to then manipulate light? Thanks to a combined $1.7 million from the National Science Foundation, a research group led by faculty at the University of Pittsburgh’s Swanson School of Engineering hope to utilize “meta-atoms” to fine-tune metamaterials with light and in turn, control how they interact with the light itself. The projects are funded through the NSF’s Designing Materials to Revolutionize and Engineer our Future (DMREF) program. “Consider something like photochromatic lenses, which have a simple reaction of darkening when exposed to ultraviolet light, and then lighten when you return indoors,” explained M. Ravi Shankar, principal investigator and professor of industrial engineering at the Swanson School. “Instead, if we harness the light to physically manipulate arrays of nano-scale structures we call meta-atoms, we can program much more complex responses.”Because of the complexity of the problem, Dr. Shankar assembled a multi-disciplinary team from three other universities: Mark Brongersma, professor of materials science and engineering at Stanford University;  Robert P. Lipton, the Nicholson Professor of Mathematics at Louisiana State University; Hae Young Noh, assistant professor and Kaushik Dayal, professor of civil and environmental engineering at Carnegie Mellon University. The team hopes to discover new classes of dynamically programmable metamaterials using theories of plasmonic structures, which are aided by machine-learning algorithms. These will feed into experimental efforts to fabricate these structures. Ultimately, the team envisions demonstrating a range of optical components, including beam steering devices, wave-front shaping systems and polarization converters, which are organized and controlled at the nanometer-scale. This would make them orders-of-magnitude more compact than conventional optical systems. Furthermore, these devices will be powered directly using light itself, without relying on electronics or on-board power sources. This opens a pathway for integrating these compact optical elements in applications ranging from autonomous vehicles, biomedicine and communication devices. ###

Youngjae Chun Receives American Heart Association’s 2020 Innovative Project Award

Bioengineering, Industrial

PITTSBURGH (Aug. 21, 2019) —Coronary artery disease is a leading cause of death in the U.S., with about 370,000 Americans dying from the disease each year. Stents are a life-saving procedure used to prop open narrowing blood vessels; however, over time, tissue can regrow into the mesh stent and cause the artery to narrow again, putting the patient at risk. Knowing that regrowth is happening as soon as possible is crucial in saving the patient’s life, but monitoring is a challenge. Youngjae Chun, PhD, associate professor of industrial engineering and bioengineering at the University of Pittsburgh’s Swanson School of Engineering, has received a funding award from the American Heart Association for his project creating a stent that will use sensors to monitor for signs of restenosis and alert the patient’s doctor without the need for endless follow-up visits. Dr. Chun’s project has been selected by the American Heart Association for its 2019 Innovative Project Award, which supports highly innovative, high-impact research that could lead to major advancements and discoveries that accelerate cardiovascular and cerebrovascular research. The award includes a total of $200,000 over two years and began on July 1, 2019. “Stenting to treat coronary artery disease is a well-established and widely used interventional procedure. This new stent will minimize the follow-up imaging procedures that can be inconvenient, expensive, and sometimes invasive for the patient,” says Dr. Chun. “Our device would continuously monitor restenosis providing valuable information to the patients.” This project will be conducted through a multidisciplinary collaboration with W. Hong Yeo, PhD, assistant professor of Department of Mechanical Engineering at Georgia Tech and John Pacella, MD, cardiologist at UPMC. “Real-time surveillance would be critical for the patient whose stented blood vessels are re-narrowing, putting them at risk for heart attack or stroke,” says Dr. Chun. “The device would provide critical information directly to patients and their doctors and could potentially save many lives.”

IE Students Help a Local Caterer Develop a Recipe for Success

Industrial, Student Profiles

PITTSBURGH (August 21, 2019) … A team of industrial engineering (IE) students from the University of Pittsburgh Swanson School of Engineering created a solution to help a small business owner increase production of her popular cookies that tell the tale of Pittsburgh’s storied jazz history. With the students’ help, Leeretta Payne will be able to expand operations of her catering company, the Legacy Café, and help preserve the jazz culture in a time of rapid revitalization. Throughout the twentieth century, Pittsburgh’s historic Hill District neighborhood was home to many clubs frequented by local and national artists. The Hill was an influential part of Payne’s life so she uses her business as an opportunity to teach customers about the neighborhood’s celebrated past. This goal was the inspiration for the Legacy Café’s “Heritage Collection” menu, which features items named after famous entities of Pittsburgh’s jazz era, such as Calloway Beans and Rice, GreenLee Spicy Cucumber, and her most famous offering - the Loendi Club Chocolate Chip Cookie. “The Loendi Club was a very elite establishment that, I believe, paints the picture of the Hill District during the ‘40s, ‘50s, and ‘60s,” said Payne. “My aunt was a singer and used to let jazz musicians spend the night at our house while they were in town. It was a fun environment to grow up in, and I want to share this history with my customers.” According to Payne, making the Loendi Club cookies is a laborious process so she sought the help of Swanson School students to develop a more efficient procedure that would increase production and reduce pain in her hands. IE students Ashley Dacosta, Elsie Wang, Keegan MacDougall, and Yang Ren embraced the opportunity for their senior capstone project, an undergraduate program where students help local businesses grow while they gain valuable industry experience. “The Industrial Engineering capstone program provides our graduating seniors with opportunities to work with a company on a real problem without a structured solution,” said Louis Luangkesorn, assistant professor of industrial engineering and coordinator of the capstone program. “Working with a small company that is community-focused like the Legacy Café requires that the students deal with issues that are very different than the big companies usually featured in their textbooks. This forces them to think differently and be creative in how they approach the problem and come up with solutions that are very specific to the individuals involved, skills that are invaluable in the world that they will be entering.” The student team met with Payne to discuss her difficulties and create a strategy to improve the way she bakes the chocolate chip cookies. Ms. Payne with students from Pitt's National Society of Black Engineers “There are two main time-consuming steps in this process: weighing each piece of the cut cold dough and molding the dough into a specific pan using one’s fingers,” explained Wang. “Ms. Payne’s current system would not be effective enough to produce the numbers demanded so our team came up with a solution that could potentially remove the weighing step and move the stress from her fingers to her arm.” The students used a mechanical extrusion tool to pump the warm dough into a uniform cylinder which was then cooled and cut into equal sized cookies, giving a uniform weight throughout. It also incorporated a tamper that would allow the cookies to be pressed into the mold, moving some of the force and pressure from the fingers to the wrist and the lower arm. “Testing showed that this new method would increase throughput by 40 percent, allowing our client to meet current demands,” said Dacosta. “Since Ms. Payne rents time at different certified kitchens, we made sure that our design was portable enough to fit her needs.” Increased demand for the cookies necessitated an updated process, and the students’ new method will help Payne produce the quantity needed for her customers. Throughout the warmer months, she is the sole cookie vendor at Pittsburgh farmers markets in the Carrick, Larimer, Southside, and Beechview neighborhoods. New opportunities like this will help Payne expand her business and spread the history of the Hill District to a wider audience. “The students and I had fun with this project,” said Payne. “I’m grateful to have had the opportunity to work with them, and I want to use my positive experiences with the University to show residents in my community the impact that can be made if we, as a greater Pittsburgh community, work together to improve our city.” The University’s work with the Legacy Café is just one example of its growing partnership with the Hill District. Pitt is opening a Community Engagement Center in the neighborhood, and while the University not yet secured a permanent facility, it continues to offer educational programming to residents. The University is also working to strengthen its relationship with a community scarred by public housing issues and displacement during the urban redevelopment movement of the late 1960s. “The University’s Community Engagement Center in the Hill District is an opportunity to reimagine the relationship between the community and Pitt, fostering mutually beneficial collaborations that advance the community’s agenda by putting our teaching, research, and capacity building programs at the service of the community,” said Kirk D. Holbrook, Director of the Community Engagement Center in the Hill District. Payne wants to see her neighborhood shine like it did during the jazz era and help current residents feel proud of where they live. She said, “I use the Legacy Café to teach my customers about the Hill District’s past because it is our history, and I don’t want people to forget it.” ###

Engaging Women in Academia

Industrial, Student Profiles

PITTSBURGH (Aug. 13, 2019) — Women in male-dominated fields can feel like their performance represents not only their ability but the ability of an entire gender. Anna Svirsko, PhD IE ‘19 found herself in such a position, often being one of the only woman in the class as she earned her doctorate in industrial engineering at the University of Pittsburgh’s Swanson School of Engineering. “That can surprisingly be a lot of pressure. Sometimes people don’t think about it, but while you’re in that situation, it can be difficult to think that everyone’s perspective of how women perform is based on you,” she says. “That can make you be a little bit shy when it comes to asking questions. You don’t want to make it seem like you’re not following what the rest of the class is following.” Dr. Svirsko elaborated on her experience in a video for the Spotlight on Women Leaders program, which was created by the Provost’s Advisory Committee on Women’s Concerns (PACWC) to highlight women whose actions model good leadership and have made a difference in the Pitt community. Dr. Svirsko is now an assistant professor at the U.S. Naval Academy. While at Pitt, she worked as a research assistant with Geisinger Health System and Children’s Hospital of Pittsburgh doing data analysis and writing programs that would help streamline processes there. She was president of the University of Pittsburgh’s INFORMS chapter, an organization that helps prepare graduate industrial engineering students for academia and industry. She earned her master of science degree in statistics and operations research from the University of North Carolina Chapel Hill and her bachelor of science degree in mathematics from Carnegie Mellon University. While Dr. Svirsko found a welcoming environment at Pitt, she recommends simple steps that can help women feel like they belong in male-dominated fields like hers. “People don’t realize the influence of just having a woman speaker at seminars every once in a while,” she notes. “Whenever I was president of INFORMS, we would invite two speakers over the course of the year, I made sure we invited one woman and one man so we had equal representation and so that women would get to see someone who is doing great research in that role.” Dr. Svirsko was nominated for the Spotlight by a fellow student. She joins the many women, from undergraduates to faculty and staff, whose stories are shared through the Spotlight on Women Leaders program.

Preparing for a Sustainable Future

Chemical & Petroleum, Civil & Environmental, Industrial, MEMS

PITTSBURGH (July 2, 2019) — When it comes to finding sustainable solutions for our planet, there is no time to waste. Luckily, students in the Mascaro Center for Sustainable Innovation’s (MSCI) Undergraduate Summer Research Program don’t have to wait until graduation to start working on projects that can make a big difference. From data that can help replace lead pipes here in Pittsburgh to devices that can identify and track birdsongs out in the field, students are doing work that will help solve the problems facing our planet “Our students are passionate about sustainability and truly want to make a difference in the world,” says Gena Kovalcik, co-director of MCSI. “The Undergraduate Summer Research Program gives them a chance to learn new skills while contributing to important sustainability research. Students work 40 hours a week for 12 weeks over the summer and meet weekly with their advisors. In addition to the research, students in the program have to write a final paper, produce a two-minute video detailing their work and its significance for sustainability, and give an oral presentation at the Undergraduate Research Symposium, which will be held on July 24 this year. The program, currently in its 15th year, was started in 2004 with just five students participating. In all, there are 22 MCSI Undergraduate Summer Research Program projects across the University this year. Here is a look at five of them. Recirculating Aquaculture: Managing Water Quality in a Closed System Over-fishing is a problem in many oceans and waterways, and companies are turning to land-based fish farming (recirculating aquaculture) to provide a more sustainable protein source. But one major risk is that farmed fish can end up tasting a little off—hints of earthy, musty flavors can taint some of the fish raised this way. This summer, Mason Unger, senior civil and environmental engineering major, and his adviser David Sanchez, assistant professor of civil and environmental engineering, are trying to solve that problem. “There’s a risk to flavor profiles of farmed fish because of an off-flavor produced by chemical compounds like geosmin. To avoid this, the fish go through ‘purging,’ where they run clean water through the tank over the fish for 7-10 days,” Mason explains. “During that time, they aren’t fed, so the fish lose mass, and it’s not great for water use. If you could figure out how the compounds are created and degrade them, it’d have economic and environmental benefits.” Using samples from fish farms across the country, Mason is working to verify protocols for collecting samples and detecting the off-flavors in the water. The ultimate goal is to find a way to eliminate the compounds causing the musty taste as soon as they are identified, saving water and keeping sustainable fish accessible and affordable. “The state of the industry is changing. Land-based farming systems have been around for a while, but there have been a lot of false starts,” says Dr. Sanchez. “This time is quite different, companies are scaling up successful operations and the World Bank projects that aquaculture will supply more than half of all fish globally by 2030.” Using Data to Improve Drinking Water: Identifying Lead Water Lines in Allegheny County Lead water pipes are an issue elevated to national attention when the horrific water quality in Flint, Mich., was discovered, but lead pipes are widely used in Pittsburgh, as well. The Pittsburgh Water and Sewer Authority (PWSA) is replacing those lines; in the meantime, homeowners may want to test their own water’s safety. Testing your own tap water, though, is notoriously tricky, explains Michael Blackhurst, PhD, Co-Director of Urban & Regional Analysis Program and Research Development Manager at the Center for Social & Urban Research. “There is a lot of variation in the amount of lead you’d observe in your tap water, depending on whether or not you were able to capture the water that had been stagnant in the lead pipes,” he says. “Even if you do, there is a lot of evidence that lead pipes can be coated to varying degrees, affecting how much lead will leach into the pipe.” According to Dr. Blackhurst, it is important to understand how accurate these home water tests are. Arianna Heilbrunn, senior environmental studies major, will spend much of her summer with Dr. Blackhurst combing through data from PWSA and the Pennsylvania Department of Environmental Protection (DEP) to compare home test results with the known locations of lead pipes. “We’re combining data from historical records and excavations, comparing whether the materials that we know the pipes are made from match up with the results people are getting in their homes,” she says. Generally, people are advised to test their water first thing in the morning, flushing the line by running the water for one or two minutes and then collecting a sample to send in for testing. It is not clear, however, that these guidelines provide consistently accurate results. Though previous internships put Arianna out in the field, doing water and soil testing, she wanted to learn new skills. The trove of data and the program used to sift through it will build skills that will be useful in a future career in consulting or federal environmental work, which is Arianna’s current goal for the future. By working with the PWSA and Pennsylvania DEP, the team hopes they can help lower lead exposure, something especially important for children. “From an ethics standpoint, the problem is hard to ignore,” says Dr. Blackhurst. “Lead has a greater effect on children, and they have no say in how much lead they’re exposed to.” The data the team is working with can help not only see where the city’s lead pipes are but can also predict where they’ll find lead lateral lines, which bring the water from the main line to the house, even if homeowners aren’t aware of them. “People don’t want to know [how much lead is in their water], but they should want to know,” says Arianna. “Everyone thinks of Flint’s water as a tragedy, but no one wants to hear that their own water contains lead, too.” Using acoustic sensors and machine learning to locate birds and bats in the field It took a little time for Jiade Song, senior industrial engineering major, to get used to working in the Kitzes Lab, a biology lab. But now that he has, his work will contribute to a system that can record birds in the field and, using AI and machine learning, learn to locate the sounds and tell which creatures are making them. Eventually, they hope their software will be able to pinpoint and ID species recorded in the field on a device called the AudioMoth. “I’m in industrial engineering, and we work in all types of fields. I’ve taken a variety of courses—production optimizations, coding, data analysis and physics—but this lab was different from my previous working spots in an industrial or production department,” says Jiade. “It has been really great in helping me get used to working in a new environment.” Jiade’s particular goal this summer is creating a tool called a calibration chamber that uses code to detect if the devices are working well. The team puts a batch of the AudioMoths in the box-like device, which then plays a recording. Afterward, they use Jiade’s program to see if all of the AudioMoths are “hearing” the same sounds. The method will produce a visualized report and help the team weed out malfunctioning devices before they are sent into the field, or check their quality after spending weeks outdoors. “One cool thing here is that Jiade is here as an engineer, and I’m an engineer,” says Trieste Devlin, a technician in the Kitzes Lab. “Dr. Kitzes is intentional about creating an interdisciplinary approach to biology.” What the Frack: Designing nanocatalysts for responsible use of natural gas “Fracking” is a buzzword that most people, especially in western Pennsylvania, are familiar with. It is at once an important economic driver in the state and a process that has a striking environmental impact. This summer, Albert Lopez-Martinez, a junior chemical and petroleum engineering major, is working with Götz Veser, PhD, professor of chemical and petroleum engineering, to find ways to make fracking more sustainable. “When fracking happens in oil shales, natural gas is burned off using flares. Instead of combusting it we’re trying to find a way to convert it into a more viable, eco-friendly alternative by turning methane into benzene,” says Albert. “My job is to help find that catalyst, varying parameters and seeing how it is affected by microwave heating.” In collaboration with Shell, West Virginia University and the Department of Energy’s National Energy Technology Laboratory (NETL), the team is looking for a new way to convert methane to a liquid chemical like benzene. This would make it a valuable chemical resource that could be transported, lessening the environmental impact while acting as an economic boon in the region. “Here in Pennsylvania, we’re not doing as much flaring, but the issue is that our natural resources are being stripped from under us, and we are left with nothing but the pollution,” says Dr. Veser. “If we can turn natural gas into a valuable product on its own here in the region, it could balance the environmental impact with a positive economic impact.” For Albert, the project is an opportunity to get started on work he is passionate about. Now that he has gotten involved in research, he is considering pursuing a masters or even a doctorate after graduation. “I know I want to work in sustainability, giving back to the community and working against climate change,” says Albert. “The Mascaro Center’s summer research program seemed like a good fit for my future goals. Durable Antireflective, Anti-Soiling and Self-Cleaning Solar Glass When it comes to renewable energy, solar panels are perhaps the most promising. There is more energy in the sunlight that hits the earth’s surface in one hour than all of humanity uses in an entire year. But solar panels do have their challenges: conventional solar panels only convert about 20 percent of the sun’s light to electricity. The top glass on a solar panel is partially reflective, losing valuable rays that could be converted to energy as they bounce off the glass. Solar panels may also be installed in desert and urban environments, where particulates and pollutants may dirty the glass, resulting in less sunlight being converted to electricity. Sooraj Sharma, senior materials science and engineering (MSE) major, has been working with Paul Leu, PhD, associate professor of industrial engineering, since last summer on a way to make anti-reflective, anti-soiling and self-cleaning glass for solar panels. While conventional anti-reflective coatings aren’t effective against all wavelengths, the team in Leu’s lab is using sub-wavelength nano-structures to reduce broadband reflection over a wide range of incidence angles to as low as 0 percent. In addition, the glass repels water and can use naturally forming dew droplets to remove dirt. Last year, they were able to show these properties on a four-inch piece of glass, but this year, they’re hoping to improve the method so it could be used to create the glass for solar panels, which are usually over one square meter. “The end product will have the same properties, but this year, our big focus is on using larger and more scalable methods that could translate to the factory level,” says Sooraj. “The viability of this glass depends on the ability to recreate it with more robust and scalable methods.” Sooraj and the team are looking at not only the process used to coat the glass but the method used to apply it. “We’re looking at scalable methods to deposit the coating on the glass, and we’re engineering that glass to be more anti-reflective to different angles and wavelengths,” explains Sooraj. The new process Sooraj is working with is called sol-gel, an extremely powerful fabrication process that can effectively produce a large variety of material end products. For solar, this means creating a porous, antireflective coating that should achieve similar results to the conventional nanostructures. The upside is that this method is far more economical, as creating the latter requires the use of expensive machines that operate on a small scale. Though Sooraj’s original interest was in working with silicon and other semiconductor materials, he was surprised to find that he found glass so fascinating to work with. “As a sophomore, I was feeling the pressure to get a co-op, but most of the ones I found weren’t that interesting to me,” he says. “When I talked to my adviser, Dr. Nettleship, he suggested I look into the Mascaro Center for Sustainable Innovation Undergrad Summer Research Program. I found this project to be really interesting with enormous real-world potential, and I was later able to continue working on it throughout the rest of my junior year. I never knew working with glass would be so interesting to me. I think it confirmed and aligned my interests.” Last year, Sooraj won the Best Presentation Award at the Mascaro Undergraduate Research Program Symposium and later submitted his summer findings to Science 2018, where he won the Innovation Institute’s Award for Best Poster on Innovation. Sooraj presented his work this year at Allegheny SolarFest at Frick Environmental Center on June 23, marking the second year in a row they attended the event. Though the event is usually represented by community groups and solar panel vendors, Sooraj felt their contribution was valuable. “We were sort the ‘black sheep’ of the event,” says Dr. Leu. “But I know the other attendees found our research interesting and valuable, and we were excited to present again.” ### Other Opportunities for Undergraduate Research Beyond the MCSI Undergraduate Summer Research Program, students have plenty of opportunities to pursue research alongside renowned faculty before donning their caps and gowns.

Louis Luangkesorn and Rachel Chung represent the INFORMS program to receive the 2019 Outstanding Community Partner Volunteer Award

Industrial

Originally published in INFORMS Analytics. Reposted with permission. Louis Luangkesorn, INFORMS member and assistant professor of industrial engineering at the University of Pittsburgh, was awarded the Outstanding Community Partner Volunteer Award from Houston Methodist Hospital, along with Rachel Chung, clinical associate professor of business analytics at College of William and Mary, for their work on volunteer on-boarding and retention analytics done as part of the INFORMS Pro Bono Analytics program. The award is given to the community partner that made the greatest impact within the department, and is presented as part of the Annual Volunteer Appreciation event for Houston Methodist Hospital (HMH), an event organized by the Volunteer Services department of HMH. The Houston Methodist Hospital project was announced as a question of what factors affect volunteer retention. Luangkesorn and Chung both had experience with volunteer retention projects and research, which made them a great fit for the HMH project. “We thought that this project would provide an opportunity to put into practice some of our thoughts on how to look at volunteer retention as well as provide a student an opportunity to work with a data analysis project from the very beginning,” said Luangkesorn. The team started the project by examining the data sets, which presented difficulty because the data was in a form that was common in data on staff and abilities but not amenable to analysis. They conducted an exercise in data munging to convert the data into standard forms and then developed a number of visualizations of the volunteers including their geographic distribution, age, employment status, volunteer roles and tenure (length of volunteering). Presenting data to a nontechnical audience is an important part of the decision-making process. “Our Volunteer Services staff has very little analytical knowledge, and the community partners [Pro Bono Analytics team] were able to break down the information in a way for us to understand,” said Cheronda Rutherford, senior volunteer coordinator at Houston Methodist Hospital. Luangkesorn and his team chose to present their exploratory data analysis with a discussion on how the Houston Methodist Hospital Volunteer staff could interpret the output and take action based on different presentations. The team presented several visualizations in a dashboard to track volunteer activity, number of active volunteers, new volunteers and volunteers becoming inactive. Using a Jupyter Notebook – a notebook that can be shared via Dropbox, GitHub, etc. – with the code hidden allowed the dashboard to be viewed in any browser and allowed the team to provide text to remind HMH staff how to interpret the results alongside the plots. As a result of this Pro Bono Analytics project, HMH is in the process of updating its computer system to use the dashboard created by Luangkesorn and Chung. Luangkesorn has been an INFORMS member since 1999, joining as a student member while completing a Ph.D. program in industrial engineering at Northwestern University. This was his first volunteer project with INFORMS Pro Bono Analytics. ###

A Forest of Nano-Mushroom Structures Keep This Plastic Clean and Stain-Free

Chemical & Petroleum, Industrial

PITTSBURGH (June 18, 2019) ­—Technologies like solar panels and LEDs require a cover material that repels water, dirt and oil while still letting plenty of light through. New flexible materials would allow these devices to be incorporated into a variety of creative applications like curtains, clothes, and paper. Researchers from the University of Pittsburgh’s Swanson School of Engineering have created a flexible optical plastic that has all of those properties, finding inspiration in a surprising place: the shape of Enoki mushrooms. The research, “Stain-Resistant, Superomniphobic Flexible Optical Plastics Based on Nano-Enoki Mushrooms,” was published in the Journal of Materials Chemistry A ( doi:10.1039/C9TA01753D). The researchers created a plastic sheet surface with tall, thin nanostructures that have larger tops, like an Enoki mushroom. Named nano-enoki polyethylene terephthalate (PET), the nano-structures in the coating make the plastic sheet superomniphobic, repelling a wide range of liquids, while maintaining a high transparency. The surface can repel a variety of liquids, including water, milk, ketchup, coffee, and olive oil.  It also has high transparency and high haze, meaning it allows more light through, but that light is scattered. That makes it ideal for integrating with solar cells or LEDs, and combined with its flexible and durability, means it could be used in flexible lighting or wearable technology. “The key thing with these structures is the shape - it keeps liquid on top of the nanostructure. This is the best in the literature so far in terms of high transparency, high haze and high oil contact angle,” explains Sajad Haghanifar, lead author of the paper and doctoral candidate in industrial engineering at Pitt. “We show that substances that usually stain and leave residue behind, like mustard and blood, fall completely off the surface, even after they’ve dried.” Videos show how the dried mustard and blood flake off the surface when the surface is tilted. “The lotus leaf is nature’s gold standard in terms of a liquid-repellant and self-cleaning surface,” says Paul Leu, PhD, associate professor of industrial engineering, whose lab conducted the research. Dr. Leu holds secondary appointments in mechanical engineering and materials science and chemical engineering. “We compared our nano-enoki PET with a lotus leaf and found that ours was better at repelling more kinds of liquids, including olive oil, blood, coffee, and ethylene glycol. The surfaces not only resist staining from various liquids, but may be adapted for medical applications to resist bacteria or blood clotting.” The paper was coauthored by Sajad Haghanifar, Anthony Galante, David Pekker and Paul Leu, from Pitt’s Swanson School of Engineering, and Luke M. Tomasovic from the Georgia Institute of Technology. The work was supported in part by a National Science Foundation CAREER Award.

Pitt Undergraduates Win First Place in Ergonomics Design Competition

Industrial

PITTSBURGH (March 20, 2019)—Undergraduate students from the University of Pittsburgh Swanson School of Engineering won first place this year at the International Ergonomics Design Competition hosted by Auburn Engineers, Inc. “We only had one team enter in this competition in the fall, and they came in first place,” says Joel Haight, professor of industrial engineering and director of Pitt’s Safety Engineering Program. Dr. Haight is faculty advisor to the Ergonomic Design Competition teams. “I’m especially proud of our students’ innovation in this event, and the application of their coursework to solve a workplace issue.” The award grants the team a $5,000 towards a professional conference of their choice in 2019, as well as $300 per team member, a team plaque, certificates and the “eTools” Prize Statue. Throughout the fall semester, students worked on two design projects and two lightning round smaller design solution applications All of these projects required that the students identify workplace ergonomic stressors and apply design principles to alleviate them. The most significant of these was to develop solutions to address the ergonomic stress associated with working in the cramped quarters of a food truck. The winning team is comprised of five industrial engineering majors who were enrolled in Dr. Haight’s Human Factors Engineering course.  They are Alexander Hartman, Maiti Keen, Megan McCormick, Dina Perlic, and Abigail Pinto. The University of Pittsburgh teams have historically done well in this competition, coming in second place for the past three years. With this win, they are making their debut in first place.

Shifting Into High Gear

Industrial, MEMS, Office of Development & Alumni Affairs

David Kitch holds two degrees from the University of Pittsburgh, but his connection to the Pitt community extends far beyond that. Kitch earned a Bachelor of Science in Mechanical Engineering (1968) and a Master of Science in Industrial Engineering (1981). Kitch first became aware of the University of Pittsburgh at a young age, working in his father’s automobile repair shop, Kitch’s Auto Service, located in Slickville, PA, 30 miles east of Pittsburgh in Westmoreland County. It was here that he gained an interest in engineering through rebuilding engines, transmissions, carburetors and more when he was just 10 years old. Kitch would often talk about his engineering interest to the shop’s customers, which included UPMC doctors and University of Pittsburgh instructors. They all encouraged Kitch to consider Pitt when the time came to apply to college. While Kitch originally intended to apply for a scholarship to the US Naval Academy, tuition benefits and other perks for the Westmoreland County native led him to attend the University of Pittsburgh Greensburg, which offered a pre-engineering curriculum. Kitch attended Pitt Greensburg for two years and then transferred to the Oakland campus in 1966. When he got to Oakland, Kitch joined the American Society of Mechanical Engineers (ASME) and the Society of Automotive Engineers (SAE) as a student member. Kitch fondly remembers attending classes in Engineering Hall and eating brown bag lunches with other commuter students. Because of his interest in energy conversion and turbomachinery, he especially enjoyed his thermo-fluids classes. Kitch says his most influential instructors were Dr. Blaine Leidy who taught Thermodynamics 1 and 2 and Dr. Joel Peterson who taught Fluid Mechanics.  Kitch continued to work at his father’s repair shop throughout his undergraduate career. While the formal co-op program had not yet been created at the time, Kitch considers Kitch’s Auto Service to be one of the first co-op sponsors and he gives much credit to his work there in helping him achieve his degree.  When Kitch graduated in 1968, the job market for engineers was thriving. He recalls being frequently contacted by company recruiters. He took interviews with four companies, but his love for the Pittsburgh region ultimately influenced him to stay local and he accepted a position at Elliott Co. in Jeannette, PA. In the early ‘70s, the nuclear power field gained traction and was led by local company, Westinghouse Electric Co. Several Elliott engineers were recruited by Westinghouse, including Kitch, who was hired in 1973. Kitch spent the next 25 years working for Westinghouse in a variety of positions including; principal design engineer, marketing engineer, nuclear safety, and project engineering.  These positions afforded Kitch the opportunity to publish numerous technical papers and travel the world visiting suppliers and nuclear plants where Westinghouse equipment was installed. In the late 70s, Kitch began attending night school in pursuit of his master’s in Engineering Management. He notes, “I was most influenced by Dr. David Cleland, my project management professor who was also well known for his publications on the subject. Dr. Cleland asked me if would critique one of his books and I did.  I reviewed the many papers submitted by authors and picked the best, to which I was mentioned in his book and received three credits toward my degree.” Kitch was also named to the IE National Honor Society in 1981. In a long and prosperous engineering tenure, Kitch is able to identify many highlights. One highlight that particularly stands out to Kitch was when his position at Westinghouse was to mentor three young engineering new hires to work on the AP-1000 plant design. One of the three hires was a Pitt Mechanical Engineering graduate named Kyle Noel. “Kyle and I formed the pump design team for the AP-1000 and we traveled to Europe, California, and throughout the US for four years. When I retired from this job, Kyle assumed command and we have remained close friends today.”During Kitch’s time as a design engineer for Westinghouse, he stayed in touch with two of his Pitt classmates, Bernard "Bernie" Fedak and Wilson Farmerie. These men recruited Kitch to serve on the then Mechanical Engineering Department Visiting Committee, an important service the three of them still do today, 25 years later. In October 2016, Kitch received from Dean Holder a MEMS Department Service Award for his impactful and dedicated commitment to the Department and the Swanson School of Engineering in general.Currently, Kitch is an engineering consultant working for Vinoski and Assoc. Inc., and McNally LLC. “My work consists of expert witness testimony support, failure and root cause analyses, reliability/design audits, and project management.” Kitch never lost his passion for cars. He supports the Pitt FSAE team as a booster, spectator and fan. He serves as a judge for the National Corvette Restorer’s Society.  He has also restored several Corvettes and currently owns three, which he keeps in a garage he calls Dave’s Corvette Corner.

Pitt IE students help the Mid-Atlantic Mothers’ Milk Bank Provide More Nutritious Milk to Preterm Babies

Industrial, Student Profiles

PITTSBURGH (March 1, 2019) … The nutritional benefits of breast milk can positively impact the health of infants, particularly those who were born prematurely and require the immunological contents that fortified formulas cannot provide. The Mid-Atlantic Mother’s Milk Bank (MAMMB) is a Pittsburgh non-profit organization that provides pasteurized milk from carefully screened donors to mothers who are not able to produce their own, and a group of University of Pittsburgh industrial engineering students teamed up with them to optimize the nutritional contents of the donated milk. This project was part of the fall 2018 Industrial Engineering Senior Design course in the Swanson School of Engineering. Team members included Jennifer Lundahl, Nick Kelly, Julian Mandzy, and Aster Chmielewski, and they were advised by Lisa Maillart, a professor of industrial engineering who had previous experience working with a milk bank in Texas. MAMMB serves hospitals and outpatient infants with medical needs in PA, WV, NJ, and MD, giving Maillart and the students an opportunity to help serve the local community. “The milk donation process consists of thawing milk deposits, pooling deposits from multiple mothers, bottling the pools, and pasteurizing the pooled milk,” said Maillart. “The product is then delivered to newborn intensive care units (NICUs), which have an acute need for the milk because of the increased health risks among premature infants.” The project scope was inspired by MAMMB’s recent purchase of a MIRIS Human Milk Analyzer, which yields accurate analysis of the macronutrient content of milk samples, allowing technicians to monitor the milk’s protein and caloric content. MAMMB wanted to create a process to optimize NICU-grade milk production by target pooling milk deposits based on nutritional content. In order to implement target pooling, the IE student group needed to create a pooling model, donor deposit database, and a standard operating procedure. According to the students, a donor deposit database was created to allow MAMMB to make thawing decisions with insight to historical donor macronutrient information rather than expiration date alone. To create the database, donor nutritional data was compiled into an Excel pivot table that includes basic caloric statistics such as donor minimum, maximum, and a weighted average. The addition of these values mitigates the risk of thawing a group of deposits with contents above or below the desired range. The resulting processing time for each optimized bottle increased from 97 seconds to 114 seconds, but the benefits of target pooling are significant, and the students hypothesized that the processing time may decrease as technicians become more familiar with the procedure. “This milk, which leverages the natural variations between mothers, will help drive better growth in preterm babies,” said Cyndy Verardi, director of operations at the Mid-Atlantic Mothers’ Milk Bank.  “It’s was an awesome semester and we are looking forward to utilizing their findings as we constantly work at improving outcomes for babies all across Pennsylvania, West Virginia, and the Mid-Atlantic region.” The Senior Design course allows Swanson School students to gain valuable industry experience with local companies. “We work with a diverse set of industry partners around Pittsburgh to identify problems that take advantage of the range of skills learned in class, the industrial experiences the students have from internships and cooperative engineering programs, and the experiences of our faculty,” said Louis Luangkesorn, assistant professor of industrial engineering and coordinator of the senior design course. “The project puts the students in a setting where they have to work with the customer to identify the underlying problem and develop a solution within a limited time frame that could be implemented by a client with limited technical resources.” Funding for this work was provided by the National Science Foundation Grant CMMI-1537992, “Optimal Management of Donor Milk Banks.” ###

Pitt Industrial Engineering Students Apply Their Knowledge in a Collaboration with Grane Rx

Industrial, Student Profiles

PITTSBURGH (February 4, 2019) … A group of University of Pittsburgh industrial engineering undergraduate students spent the fall 2018 semester helping a local pharmaceutical supplier balance production and optimize distribution strategies. The work was part of a Swanson School of Engineering senior capstone project, a program that allows students to gain valuable industry experience with local companies while pursuing their degrees. “We work with a diverse set of industry partners around Pittsburgh to identify problems that take advantage of the range of skills learned in class, the industrial experiences the students have from internships and cooperative engineering programs, and the experiences of our faculty,” said Louis Luangkesorn, assistant professor of industrial engineering and coordinator of the department’s capstone program. “The project puts the students in a setting where they have to work with the customer to identify the underlying problem and develop a solution within a limited time frame.” The group of undergraduates worked with Grane Rx, a pharmaceutical supplier for Programs of All-Inclusive Care for the Elderly (PACE),  skilled nursing centers, and personal care homes in multiple states on the East Coast. The company is planning an expansion of their PACE Pharmacy services to the West Coast with a significant amount of new participants expected in a short period of time. To help manage this growth, Grane Rx recruited the help of Pitt IE students and faculty to strategize ways to meet production and distribution needs. The students’ first goal was to create a working production scheduling model that optimizes weekly and daily production and allows for business growth. The second goal was to provide a weekly production cost analysis that compares the options for overtime production once the new Colorado facility reaches its capacity. “We created both models by having meetings with the Grane Rx resources, analyzing data sets provided by the company, holding group design sessions, and coding in VBA and Matlab,” said Julie Shields, who recently graduated with a bachelor’s degree in industrial engineering. “The project helped improve our coding and project management skills, both of which may be useful in our future careers.” As part of the capstone, students created weekly progress reports and met with Grane Rx employees along with University of Pittsburgh faculty who served as mentors and advisors. Quintin Graciano, an operations project manager who helped supervise the group, said, “The production model created by the students provided Grane Rx a fresh and unique view of our new PACE production processes. We have incorporated several new production tools at our Denver PACE pharmacy. The students were engaging and committed to providing a tool that made a difference.  Mission accomplished!” According to Shields, the most important skill that the group gained was effective delegation based on the talents of each team member. She said, “Being able to improve these skills and gain meaningful industry experience before we graduate was extremely valuable.” The team presented their project at the Swanson School of Engineering’s Fall 2018 Design Expo where they took first place in the industrial engineering category. Dr. Luangkesorn said, “The work with Grane Rx provided a good example of a project that showcased the abilities of our partner and our students, enhancing the students’ project management and technical skills while helping local industry grow.” ### About Grane Rx For nearly 25 years, Grane Rx has been a leader in pharmacy solutions and services for PACE organizations and post-acute care providers across the United States. Our customer centric pharmacy approach optimizes Care Center operations so providers can deliver the most seamless, accurate and convenient pharmacy experiences to their patients and participants. Our PACE Pharmacy Solutions include Meds2Home packaging, EasyRead Pharmacy labels, and LearnRx literacy tools available in 22 different languages, which are designed to revolutionize pharmacy services and outcomes. Grane Rx leverages senior care pharmacy experts and the newest technologies to provide universal, best-in-class service to patients, participants and Centers alike.
