Polymer thin films can extend the lifespan of everyday products, such as food packaging for preserving freshness and protective coatings for electronics. Advancing their design to be even thinner and more durable could expand their applications further.

Kōnane Bay, an assistant professor based in the University of Colorado’s Department of Chemical and Biological Engineering, recently received a prestigious CAREER Award, a $675,000, five-year grant from the National Science Foundation. The funding will advance her work in polymer characterization and support the development of high school and summer program curricula that integrate materials science and engineering lessons with traditional Indigenous knowledge.

“It feels great to be recognized by the polymer community for both the scientific and outreach work that we are doing,” Bay said.

The award will support Bay and her team at the Huli Materials Lab in investigating how the mechanical properties of polymer films evolve as their thickness is reduced to less than 100 nanometers—about a thousand times thinner than a human hair or cling wrap. Many industrial applications depend on the mechanical performance and stability of these films. The difficulty, Bay said, lies in the fact that when polymer materials are processed into thinner films, their mechanical strength changes in ways that are not yet fully understood.

Assistant Professor Kōnane Bay oversees a graduate student working on an instrument in the Huli Lab.

Using a custom-built instrument, researchers in the Huli Lab will study how variables like thickness, temperature and surface interactions affect the strength of these films. The findings will provide valuable insights for designing more reliable adhesives, coatings and membranes while reducing material costs, energy use and environmental waste.

The project will fund a PhD student for five years to study the mechanics of ultrathin polymer films.

In addition to supporting research, the funding will enable the development of high school and summer program curricula that integrate materials science and engineering with traditional Indigenous knowledge. Growing up in Hawaiʻi, Bay draws from her heritage to shape this initiative, which aims to increase STEM recruitment and retention among women and historically excluded students, particularly Native Hawaiians, through curriculum development, outreach and mentoring to inspire the next generation of diverse STEM leaders.

“The curriculum will be designed to inspire high school students across Colorado and Hawaiʻi to explore and pursue advanced degrees and careers in STEM disciplines,” Bay said.

Building a just future: Why graduate research must include energy justice Susan Glairon Mon, 11/25/2024 - 16:17

Susan Glairon

In a comment published in “Nature Chemistry,” on Nov. 25, Casey Davis, a chemistry PhD student, along with her advisor, Mike Toney, a professor of chemical engineering and materials science, and others, argue that universities must integrate energy justice into graduate curricula and research.

CU Boulder spoke with Toney and Davis about energy justice and the importance of preparing graduates to tackle these challenges in their careers as the world transitions from fossil fuels to renewable energy.

What is energy justice?

Davis: Energy justice means ensuring fairness in how energy is produced and used, as well as addressing past harms experienced by disadvantaged communities.

Can you explain the social aspects of energy justice?

Davis: Community solutions involve engaging with communities to understand their needs, rather than having scientists and policymakers make decisions in isolation. For example, while coal is harmful, communities reliant on it for jobs and the local economy may have different perspectives. Addressing their concerns can foster broader support and accelerate progress, rather than facing resistance.

Mike and I have worked to integrate this focus into our fundamental research, which I find very rewarding.

Toney: As an example, one of the first-year chemical engineering graduate students, Summer-Solstice Thomas, is proposing to specifically engage local communities impacted by Per- and polyfluoroalkyl substances (PFAS), or so-called “forever chemicals,” in her graduate research aimed at improving membranes to remediate PFAS.

Why do graduate students need to understand energy justice?

Davis: Students who understand both the scientific and social aspects of climate change will develop better and more implementable solutions to address environmental challenges in ways that minimize harm to vulnerable communities and address previous injustices.

In STEM, PhD students often focus on their specific science and don’t have all the skills needed to contribute to a just energy transition. For example, students working on renewable energy may learn how batteries work, but not about the negative impacts of mining the materials needed for them.

What are some of these potential negative impacts?

Davis: Sourcing materials and establishing sites for renewable energy can negatively impact adjacent communities in ways similar to fossil fuels. For example, the cobalt mined in the Democratic Republic of the Congo for lithium-ion electric car batteries, has led to severe injustices, including child labor and mining deaths.

Casey Davis

How have scientists historically approached energy justice?

Toney: Historically, many scientists, including myself, have only superficially addressed this issue. However, there is a growing awareness among early-career scientists about its significance. We need to integrate these considerations into our technical work. Recently, there’s been a significant increase in student interest in energy justice. In my experience, recent engineering students are particularly passionate about energy and environmental justice.

Davis: This growing demand highlights the need for professors and academic institutions to consider these concerns more in their teaching and research. It’s essential to address these issues in graduate school, where future scientists and engineers are trained. By teaching students the importance of energy justice and how to incorporate it into their work, they can apply these principles in their careers, whether in industry or regulatory agencies like the EPA.

Are there barriers to integrating energy justice into research?

Davis: PhD students might hesitate to add this new focus due to concerns about extending their graduation time and potential pushback from advisors. Additionally, some journals and reviewers have been resistant.

Toney: Incorporating these concepts at the PhD level has been challenging, but Casey and other students have successfully integrated energy justice into their research, receiving positive feedback during exams. In my generation, nobody really ever thought about this.

Professor Mike Toney

How can these barriers be overcome?

Davis: Solutions should be tailored to each institution, but incorporating more diversity, equity and inclusion initiatives is essential, a point that we discuss more in the Comment. Schools can develop interdisciplinary programs and hire faculty who support these approaches to encourage a culture shift. Equity can become part of the curricula and dissertations of science graduate students. While it’s challenging, these incremental changes have significant impact. We’re already seeing progress.

What is changing in CU Boulder’s graduate program?

Davis: Mike is encouraging me to incorporate energy justice into my dissertation. This sort of support from professors is necessary for graduate students to begin to develop a holistic understanding of how their work fits into larger issues such as climate justice.

Toney: CU Boulder is proposing a new approach to graduate education through an NSF grant proposal. The plan integrates fields like communications, business and social sciences into PhD programs, giving students across disciplines a broader understanding of engineering and science. This multidisciplinary training prepares our students with the tools needed to apply these concepts in their careers end enable a just energy transition. I see this as expanding engineering education to include broader training which would extend into the undergraduate level.

This approach will better equip our graduates to make a more significant, holistic impact in the world.

How will you be integrating energy justice into graduate curricula here at CU Boulder?

Toney: I will be teaching a new one-credit class Spring semester on “Energy Justice in Engineering.”

Do you have a vision for how incorporating energy justice at a college level might evolve?

Davis: I envision energy justice becoming integral to STEM education, where students not only learn science and engineering concepts but also understand its social implications. Solving climate change is also about addressing social issues. If we resolve social inequalities, it would significantly advance our climate goals. For instance, equitable public transportation reduces emissions and supports broader access. It’s about creating a more abundant and connected community.

CMBE’s Rising Star awards are presented annually to a distinguished group of exceptional junior principal investigators each year. In recognition of her accomplishments, Hind was invited to present her research findings in January at the 2025 BMES-CMBE conference in Carlsbad, California.

"I am very excited to accept this award," Hind said. "It highlights the innovative research the students in my laboratory are conducting to better understand the fundamental mechanisms of immune cell signaling and their potential impacts on human health."

Hind’s work focuses on using engineering principles to better understand the immune response to diseases. Her lab studies how inflammation, cell-cell interactions and the surrounding tissues influence the immune response, with the long-term goal of finding new drug targets to help treat diseases.

For five years Hind's laboratory has been investigating the fundamental mechanisms that regulate the innate immune response to inflammation, with a focus on bacterial infections. The research aims to understand how cells integrate the myriads of signals in an inflammatory environment into an efficient and effective response. During an innate immune response, innate immune cells receive signals from pathogens, blood vessels and tissue cells and react within minutes to protect against infection.

"This award honors our work investigating how this response fails following sepsis, leading to an increased risk of infection," she said. "This could have profound applications for the way in which we treat patients who recover from sepsis.”

Laurel Hind, an assistant professor of chemical and biological engineering, has been recognized with the Rising Star Award from the Biomedical Engineering Society - Cellular and Molecular Bioengineering Special Interest Group.
