Making a PAWS-itive Impact

Chemical & Petroleum

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.” # # #

PITTSBURGH (April 9, 2021) … The Controlled Release Society (CRS) has announced that University of Pittsburgh Professor Steven R. Little will receive its Distinguished Service Award at its virtual annual meeting this July 25-29. Little, the William Kepler Whiteford Endowed Professor and Chair of the Department of Chemical and Petroleum Engineering at Pitt’s Swanson School of Engineering, is internationally recognized for his research in drug delivery systems that mimic the body’s own mechanisms of healing and resolving inflammation.This is Little’s third honor from CRS; in 2018 he received the society’s Young Investigator Award, and in 2020 was elected to its College of Fellows for “outstanding and sustained contributions to the field of delivery science and technology over a minimum of ten years.”“Dr. Little's leadership of the focus groups of the Controlled Release Society has been transformational for the society as a whole,” said nominator Justin Hanes, the Lewis J. Ort Professor of Ophthalmology at the Johns Hopkins University School of Medicine. “I have never seen the young rising superstars of our field so engaged in the CRS, and their engagement is key to the long-term success of this remarkable scientific society. Dr. Little has also been a highly valued member of the CRS board of directors.  He is a visionary and a natural leader. We are so grateful to him.”Rather than traditional drug treatments that are distributed throughout the entire body, Little’s controlled release research focuses on time-released microcapsules that target specific cells on site. In 2020, Little published a groundbreaking discovery of a new immunotherapy system that mimics how cancer cells invade the human immune system and thereby reduces the risk of transplant rejection. He has also made advancements to the fundamentals of delivery science with predictive models enabling rational design of drug delivery systems, leading to the founding of Qrono Inc., a specialty pharma company in Pittsburgh.“The CRS is a tremendous organization, and I am extremely humbled by this recognition. A large number of people sacrificed so much of their time to achieve the positive changes that this award is recognizing. I am very confident that I speak for all of these people when I say how rewarding it is for all of us to see the next generation of scientists and engineers being recognized for what they do and having a way to exercise their own leadership in this world-class organization.”More About Dr. LittleDr. Steven Little is a William Kepler Whiteford Endowed Professor of Chemical and Petroleum Engineering, Bioengineering, Pharmaceutical Sciences, Immunology, Ophthalmology, and the McGowan Institute for Regenerative Medicine at the University of Pittsburgh.

"I sincerely congratulate this year's honorees." The University offers guidance for students who want to prepare strong applications for these and other awards. “Students in the Swanson School of Engineering successfully compete every year for NSF GRFP awards, which is a testament to their academic excellence and hard work,” said bioengineering professor Patrick Loughlin. “It is also a testament to the decade-long workshop and efforts by Swanson School faculty to assist graduate students in preparing competitive fellowship applications.” Loughlin said the Swanson School is joining forces with the University Honors College to expand its efforts with an eye toward further increasing the number of Pitt NSF GRFP recipients. Pitt Honors scholar-mentor Joshua Cannon said the Honors College’s program includes workshops throughout the summer and early fall, numerous past successful applications to read and learn from, advice on how to structure essays, and detailed reading and reviewing of essays. Awardee Marcela Gonzalez-Rubio said she felt overwhelmed as she started her NSF GRFP proposal. “Not because I didn't feel ready, but because as a graduate student it was my first time applying for such a competitive and prestigious grant. “I knew I needed mentorship, advice and new sets of eyes to provide an objective perspective on my proposal as I wanted it to be the best possible,” Gonzalez-Rubio said. “In my advisor, lab mates, fellow grad students and Pitt's Honors College prep program I found everything that I was looking for and I will be forever thankful for their support in helping me achieve what I consider to be my career's most important milestone so far.” Said honorable mention honoree Emily Bierman, "The application process allowed me to really envision what I wanted my graduate school experience to look like. After taking time to think deeply about what brought me to where I am today and what I want to accomplish, I feel much more grounded as a graduate student. Pitt's prep program really helped me through that self-reflection. The GRFP application is quite daunting, but I didn't have to do it alone."

Bioengineering, Chemical & Petroleum, Civil & Environmental, Industrial, MEMS, Diversity

PITTSBURGH (March 18, 2021) — The path for women in STEM fields has historically been fraught with obstacles that their male counterparts may not have had to face. The path is a bit clearer today thanks to the women who walked it before: women like Rachel Carson, the marine biologist and environmentalist; Katherine Johnson, the space scientist who made the Apollo 11 flight possible; and Edith Clarke, the first professionally employed female electrical engineer in the U.S. On Wednesday, March 31, 2021, in celebration of Women’s History Month, a panel of women from the Swanson School of Engineering will discuss their own paths to success as women in STEM and higher education. The six faculty and staff members will discuss their journeys and lessons learned while building their fruitful careers. The panel, “My Journey, My Story: The Path to Success for Women in STEM and Higher Education,” is presented by the Swanson School of Engineering Office of Diversity. The discussion is open to all members of the Swanson School. You can find more information and RSVP here. PANELISTS: Xinyan Tracy Cui, Professor of Bioengineering Tracy Cui runs NTE Lab, where they investigate and develop tools that interface with the nervous system for neuroscience research or clinical diagnosis and therapies. One major thrust of the lab research is to understand and modulate neural tissue interactions with smart materials and biosensors—an effort that can be applied to several fields of research, including neural electrode/tissue interface, neural tissue engineering, implantable biosensors and drug delivery. The NTE Lab also designs advanced functional biomaterials and electrode devices that will intimately integrate with the host neural tissue. They simultaneously develop rigorous methods to comprehensively and accurately evaluate these novel materials and devices.

Pitt ChemE Researchers Design Active Materials for Self-regulating Soft Robots

Chemical & Petroleum

PITTSBURGH (March 16, 2021) … During the swarming of birds or fish, each entity coordinates its location relative to the others, so that the swarm moves as one larger, coherent unit. Fireflies on the other hand coordinate their temporal behavior: within a group, they eventually all flash on and off at the same time and thus act as synchronized oscillators. Few entities, however, coordinate both their spatial movements and inherent time clocks; the limited examples are termed “swarmalators”1, which simultaneously swarm in space and oscillate in time. Japanese tree frogs are exemplar swarmalators: each frog changes both its location and rate of croaking relative to all the other frogs in a group. Moreover, the frogs change shape when they croak: the air sac below their mouth inflates and deflates to make the sound. This coordinated behavior plays an important role during mating and hence, is vital to the frogs’ survival. In the synthetic realm there are hardly any materials systems where individual units simultaneously synchronize their spatial assembly, temporal oscillations and morphological changes. Such highly self-organizing materials are important for creating self-propelled soft robots that come together and cooperatively alter their form to accomplish a regular, repeated function. Chemical engineers at the University of Pittsburgh Swanson School of Engineering have now designed a system of self-oscillating flexible materials that display a distinctive mode of dynamic self-organization. In addition to exhibiting the swarmalator behavior, the component materials mutually adapt their overall shapes as they interact in a fluid-filled chamber. These systems can pave the way for fabricating collaborative, self-regulating soft robotic systems. The group’s research was published this week in the journal Proceedings of the National Academy of Sciences (DOI: 10.1073/pnas.2022987118). Principal investigator is Anna C. Balazs, Distinguished Professor of Chemical and Petroleum Engineering and the John A. Swanson Chair of Engineering. Lead author is Raj Kumar Manna and co-author is Oleg E. Shklyaev, both post-doctoral associates. “Self-oscillating materials convert a non-periodic signal into the material’s periodic motion,” Balazs explained. “Using our computer models, we first designed micron and millimeter sized flexible sheets in solution that respond to a non-periodic input of chemical reactants by spontaneously undergoing oscillatory changes in location, motion and shape. For example, an initially flat, single sheet morphs into a three-dimensional shape resembling an undulating fish tail, which simultaneously oscillates back and forth across the microchamber.”The self-oscillations of the flexible sheets are powered by catalytic reactions in a fluidic chamber. The reactions on the surfaces of the sheet and chamber initiate a complex feedback loop: chemical energy from the reaction is converted into fluid flow, which transports and deforms the flexible sheets. The structurally evolving sheets in turn affect the motion of the fluid, which continues to deform the sheets. “What is really intriguing is that when we introduce a second sheet, we uncover novel forms of self-organization between vibrating structures,” Manna adds. In particular, the two sheets form coupled oscillators that communicate through the fluid to coordinate not only their location and temporal pulsations, but also synchronize their mutual shape changes. This behavior is analogous to that of the tree frog swarmalators that coordinate their relative spatial location, and time of croaking, which also involves a periodic change in the frog’s shape (with an inflated or deflated throat). “Complex dynamic behavior is a critical feature of biological systems,” Shklyaev says. Stuff does not just come together and stop moving. Analogously, these sheets assemble in the proper time and space to form a larger, composite dynamic system. Moreover, this structure is self-regulating and can perform functions that a single sheet alone cannot carry out.”“For two or more sheets, the collective temporal oscillations and spatial behavior can be controlled by varying the size of the different sheets or the pattern of catalyst coating on the sheet,” says Balazs. These variations permit control over the relative phase of the oscillations, e.g., the oscillators can move in-phase or anti-phase.“These are very exciting results because the 2D sheets self-morph into 3D objects, which spontaneously translate a non-oscillating signal into “instructions” for forming a larger aggregate whose shape and periodic motion is regulated by each of its moving parts,” she notes. “Our research could eventually lead to forms of bio-inspired computation – just as coupled oscillators are used to transmit information in electronics – but with self-sustained, self-regulating behavior.” Autonomous coupled oscillations of two active sheets. Two fully coated sheets are initially placed in symmetric locations about the patch. (Raj Kumar Manna) ### This work was supported by Department of Energy Grant DE-FG02-90ER45438 and the computational facilities at the Center for Research Computing at the University of Pittsburgh. 1KP O'Keeffe, H Hong, SH Strogatz.
