Seeking Sustainable Solutions for the Global Challenge of Safe Drinking Water

Civil & Environmental, Grants, Features, Banner

Lead is not the only danger when it comes to drinking water – harmful bacteria can also find their way into the water we consume despite treatment prior to distribution. In the face of water scarcity and aging infrastructure, there is a need for innovative, affordable, and portable solutions to sustainably provide safe drinking water across the globe.Engineering researchers from the University of Pittsburgh will use a $500K CAREER award from the National Science Foundation to create a sustainable material design framework to mitigate pathogen exposure in this invaluable resource.“In addition to tap water from large-scale, municipal distribution, there are many other scenarios where we may want to disinfect our water before we drink it, such as when it is sourced from private wells or nature,” said Leanne Gilbertson, lead researcher and assistant professor of civil and environmental engineering at Pitt’s Swanson School of Engineering. “There are also emerging sources of drinking water, such as water reuse where wastewater is treated to potable standards, presenting new disinfection challenges.”In this project, Gilbertson’s team will examine graphitic carbon nitride (g-C3N4), a non-metal material that possesses antimicrobial properties when activated with visible light. It is proposed as a sustainable material because it is developed with low-cost, abundant resources.“We will modify the chemistry of graphitic carbon nitride to improve its photocatalytic performance,” Gilbertson said. “When light is absorbed by the material, it generates reactive oxygen species that can kill microorganisms.”The research team will integrate the enhanced materials into a drinking water treatment device, such as a filter or portable reactor, that can be used as a viable, cost-effective solution to inactivate harmful bacteria in drinking water. They will collaborate with Aquisense, an industry leader in LED-enabled disinfection, to develop a point-of-use model.“By manipulating the structure and composition of graphitic carbon nitride at the atomic level, we have the ability to control its optical absorption and performance for photocatalytic disinfection. Using LED technology further enables us to flexibly configure the light wavelength best suited for maximum absorption of a designed material,” said Yan Wang, a postdoctoral associate at Lawrence Berkeley National Lab and former PhD student in the Gilbertson Group who started this project.Through this research, the team will assess whether this material is indeed a sustainable alternative for treating drinking water.“We will apply life cycle assessment (LCA) to investigate the environmental impacts associated with synthesizing graphitic carbon nitride,” said Nathalia Aquino de Carvalho, a current PhD student in the Gilbertson group and lead author of their recent paper that lays the foundation for this work. “LCA will enable us to identify hot spots in the synthesis, tradeoffs of different synthesis routes, and opportunities to reduce the environmental footprint prior to scaling production. Applying LCA while we are designing the material enables competitive, environmentally responsible development of graphitic carbon nitride.”Gilbertson’s group ultimately hopes to create a point-of-use device that addresses the challenge of sustainably providing safe drinking water. They also plan to develop educational resources for the general public through a podcast series and a “Science Through Storytelling” program to engage elementary students in STEM.

Self-Aware Materials for Living Structures

Research, Civil & Environmental, Banner

From the biggest bridges to the smallest medical implants, sensors are everywhere, and for good reason: The ability to sense and monitor changes before they become problems can be both cost-saving and life-saving.To better address these potential threats, the Intelligent Structural Monitoring and Response Testing (iSMaRT) Lab at the University of Pittsburgh Swanson School of Engineering has designed a new class of materials that are both sensing mediums and nanogenerators, and are poised to revolutionize the multifunctional material technology big and small.The research, recently published in Nano Energy, describes a new metamaterial system that acts as its own sensor, recording and relaying important information about the pressure and stresses on its structure. The so-called “self-aware metamaterial” generates its own power and can be used for a wide array of sensing and monitoring applications.The most innovative facet of the work is its scalability: the same design works at both nanoscale and megascale simply by tailoring the design geometry.“There is no doubt that the next generation materials need to be multifunctional, adaptive and tunable.” said Amir Alavi, assistant professor of civil and environmental engineering and bioengineering, who leads the iSMaRT Lab. “You can’t achieve these features with natural materials alone—you need hybrid or composite material systems in which each constituent layer offers its own functionality. The self-aware metamaterial systems that we’ve invented can offer these characteristics by fusing advanced metamaterial and energy harvesting technologies at multiscale, whether it’s a medical stent, shock absorber or an airplane wing.”While nearly all of the existing self-sensing materials are composites that rely on different forms of carbon fibers as sensing modules, this new concept offers a completely different, yet efficient, approach to creating sensor and nanogenerator material systems. The proposed concept relies on performance-tailored design and assembly of material microstructures.The material is designed such that under pressure, contact-electrification occurs between its conductive and dielectric layers, creating an electric charge that relays information about the condition of the material. In addition, it naturally inherits the outstanding mechanical properties of metamaterials, like negative compressibility and ultra-high resistance to deformation. The power generated by its built-in triboelectric nanogenerator mechanism eliminates the need for a separate power source: such material systems can harness hundreds of watts of power at large scales.A “Game Changer,” from the Human Heart to Space Habitats“We believe this invention is a game changer in metamaterial science where multifunctionality is now gaining a lot of traction,” said Kaveh Barri, lead author and doctoral student in Alavi’s lab. “While a substantial portion of the current efforts in this area has been merely going into exploring new mechanical properties, we are going a step further by introducing revolutionary self-charging and self-sensing mechanisms into the fabric of material systems.”“Our most exciting contribution is that we are engineering new aspects of intelligence into the texture of metamaterials. We can literally transform any material system into sensing mediums and nanogenerators under this concept,” added Gloria Zhang, co-lead author and doctoral student in Alavi’s lab.The researchers have created multiple prototype designs for a variety of civil, aerospace and biomedical engineering applications. At a smaller scale, a heart stent using this design can be used to monitor blood flow and detect signs of restenosis, or the re-narrowing of an artery. The same design was also used at a much larger scale to create a mechanically-tunable beam suitable for a bridge that could self-monitor for defects on its structure.These materials have enormous potential beyond Earth, as well. A self-aware material uses neither carbon fibers nor coils; it is light in mass, low in density, low in cost, highly scalable, and it can be fabricated using a broad range of organic and inorganic materials. Those qualities make them ideal for use in future space exploration.“To fully understand the huge potential of this technology, imagine how we can even adapt this concept to build structurally-sound self-powering space habitats using only indigenous materials on Mars and beyond. We are actually looking into this right now,” said Alavi. “You can create nano-, micro-, macro- and mega-scale material systems under this concept. That is why I am confident that this invention can build the foundations for a new generation of engineering living structures that respond to the external stimuli, self-monitor their condition, and power themselves.”The paper, “Multifunctional meta-tribomaterial nanogenerators for energy harvesting and active sensing” (DOI: 10.1016/j.nanoen.2021.106074), was co-authored by Zhong Lin Wang, PhD, Hightower Chair and Regents' Professor at Georgia Institute of Technology, Jun Chen, PhD, Assistant Professor at Pitt, and Pengcheng Jiao, PhD, Research Professor at Zhejiang University.This research is supported in part by the NIH under award number R21AR075242-01, and it is a continuation of U.S. Provisional Pat. Ser. No. 63/048943, entitled “Self-aware Composite Mechanical Metamaterials and Method for Making Same,” filed at Pitt.

First-Hand STEM Experiences From Coast to Coast

Features, Civil & Environmental

As undergraduates Heather Phillips and Amy Blanchard explained the basics of solid phase extraction and microbial fuel cells via Zoom from a lab at the University of Pittsburgh, Los Angeles high school senior Serenity Anderson left a quick but striking comment in the chat: “Really cool seeing girls in the lab :)”Anderson was part of the class of seniors from the Girls Academic Leadership Academy (GALA), a public STEM high school in Los Angeles, who arrived virtually at Pitt’s Swanson School of Engineering on April 22, 2021 to learn how data is used in engineering to support sustainability. Hosted by Mascaro Center for Sustainable Innovation (MCSI) assistant director David Sanchez, the students learned about testing water for pollution, experimented with their own water testing strips, and got a detailed tour of Sanchez’s Sustainable Design Labs.“When students visit our lab it’s so important to create opportunities for students to connect personally with the researchers as well as intellectually with the research. The pandemic has pushed us to think differently about who we can connect with and how we can be present to them, and this virtual field trip is a great example of that,” said Sanchez, who is also assistant professor of civil and environmental engineering. “I’m fortunate to be surrounded by great students and creative educators, like Jon and his team, who are eager to introduce more young people to sustainability research and get them excited about it.”The virtual field trip was organized by the University of California Los Angeles (UCLA) Science Project, which seeks to engage all students in meaningful science instruction, especially those within the Los Angeles Unified School District. The Science Project’s director, Jon Kovach, has worked with Sanchez and MCSI for the past three years on enhancing Pitt’s summer “Teach the Teacher” program utilizing the Next Generation Science Standards.“An important element of our partnership with UCLA is its connection to a girls’ STEM program. Something I definitely missed in my high school education was representation of women in STEM careers, so it was a great opportunity to provide that to young women,” said Blanchard, who just completed her sophomore year in civil and environmental engineering at Pitt. “It emphasized to me just how essential it is for under-represented groups, especially women and girls, to see themselves reflected in scientific research.”The day began with a photo of a large, freshly caught fish and a question: Would the students consider eating it? Upon revealing that the fish was caught in the Los Angeles River, almost all of the students responded that they would not. At home, the students got to use water test strips and compare results to learn about the concentration of pollutants in the water.“Working with the students showed to me just how important basic engineering skills are, like analyzing data and making conclusions from that data. We looked at test strips from the LA River in their area, and they were able to make judgments about pollution and whether it would be safe to fish in the river,” said Blanchard. “I was really impressed with the students’ ability to jump from the building blocks of data analysis to drawing complex conclusions!”After interacting in break-out groups, the students virtually toured the lab and experienced the day-to-day realities of research. The researchers in the Sanchez lab, which focuses on sustainability and water resources, explained how their work is used to monitor water quality, pollution levels in fisheries, and more.“I thought the lab tour was super cool and helped me have a better idea of what roles a researcher has to fulfill,” said GALA senior Tora Hoar Vea.“I liked seeing the projects undergraduate students were working on, learning about the problems they encountered and how they solved them,” added GALA senior Naomi Macey.“While there were a few girls who expressed appreciation for seeing Amy and me in the lab, sharing that they were happy to see women in STEM, they didn't seem to be deterred by the idea that the field is still so male-dominated,” remarked Phillips, who is earning her bachelor's degree in nanotechnology through the Engineering Science program at Pitt. “The girls in my group wanted to pursue futures in veterinary science, neuroscience, architecture, and engineering, and it was exciting to see young women choosing to pursue their interests and passions for a variety of STEM disciplines.”

Making a PAWS-itive Impact

Alumni, Civil & Environmental, Features

When CEO and founder of Pawprint Oxygen Blake Dubé (ChemE ’17) scrolled past a news story about pet oxygen masks from high schooler Carley Deery, he had to do a double take. A 17-year-old from Des Moines had raised more than $2,000 to provide pet oxygen masks in her local community.This emergency treatment is all too familiar to Dubé, who co-founded Aeronics -- a company that provides portable oxygen technology for consumer, veterinary, and medical applications. The group later created the brand Pawprint Oxygen after an acquaintance lost a pet to respiratory complications, en route to a veterinary hospital.Impressed with Deery’s entrepreneurial spirit and passion for animal rescue, Dubé decided to reach out.“We saw an opportunity to amplify her work and reach even more pets by donating $10,000 worth of pet oxygen masks to her cause,” he said. “We're a small company, and our team's average age is only a few years older than Carley. That's why this opportunity was so special -- to be able to join a cause that matches our own mission while supporting another young change-maker means a lot to us.”Deery was originally inspired by a story from her father, a Des Moines firefighter who rescued and resuscitated a puppy from a house fire. When she saw the impact animal oxygen masks can make in emergency situations, she raised both money and awareness for this treatment.Her GoFundMe campaign resulted in raising enough for nearly half of the 50 masks that were distributed, in collaboration with the Animal Rescue League (ARL) of Iowa, among ten fire departments in the Des Moines area. They will expand this effort with the donation from Pawprint Oxygen.“The plan for the additional masks currently is to reach out across Iowa with an emphasis on rural or small town volunteer fire departments who struggle for equipment,” said Tom Colvin, CEO of the Animal Rescue League of Iowa. “The ARL is occasionally on the receiving end of pets from fires so our veterinary staff will want to keep a few on hand as well.”Deery’s effort also caught the eye of Drew Barrymore, who hosts a popular daytime talk show.“Carley's work with the Animal Rescue League of Iowa shows what an impact young people can make,” Dubé added. “When she saw the difference that these masks can make for pets involved in house fires, she took action.”# # #

CEE's Xu Liang to participate in Land Ecosystem Models based On New Theory, obseRvations and ExperimEnts (LEMONTREE) project

Civil & Environmental

PITTSBURGH (March 25, 2021) ... A University of Pittsburgh team, led by Xu Liang from Swanson School of Engineering, will collaborate with top scientists around the world in a new thrust to study Land Ecosystem of the Earth in the project called LEMONTREE funded by Schmidt Futures and under the umbrella of VESRI, the Virtual Earth System Research Institute (https://schmidtfutures.com/our-work/scientific-knowledge/vesri/). The Pitt team will develop a land surface model VIC++, a significant extension of the VIC model, based on new theory and newly available rich observations. The VIC model has been widely used both nationally and internationally. It is also one of the models used in the NASA Land Data Assimilation System (LDAS). The official announcement of the thrust reads as follows:Reading University will be coordinating a new 5-year project Land Ecosystem Models based On New Theory, obseRvations and ExperimEnts (LEMONTREE) funded by Schmidt Futures and under the umbrella of VESRI, the Virtual Earth System Research Institute. LEMONTREE will develop a next-generation model of the terrestrial biosphere and its interactions with the carbon cycle, water cycle and climate.The LEMONTREE approach draws on eco-evolutionary optimality theory as a basis for building ecosystem models that rest on firm theoretical and empirical foundations, and that can be incorporated into the land-surface component of climate models. These models should eventually yield more reliable projections of future climates. This could give a newfound ability to address issues in sustainability, including the potential to maintain the biosphere’s capacity to regulate the carbon cycle while benefiting human well-being and development.LEMONTREE is an international consortium with participants from Reading, Imperial College London, Columbia University, the University of Pittsburgh, UC Berkeley, Utrecht University, Seoul National University, Texas Tech University, Tsinghua University, the Swiss Federal Institute of Technology in Zurich, the UK Met Office and the European Centre for Medium-range Weather Forecasts. Sandy Harrison, project lead for Reading University, says "The Lemontree consortium have been collaborating informally for several years, and I am very excited that with the support of Eric and Wendy Schmidt by recommendation of the Schmidt Futures program, we have the opportunity to fast-track our efforts to create a better understanding of the way the terrestrial biosphere works and how this impacts biogeochemical cycles, climate and feedbacks to ecosystem services."
