Three undergraduate researchers from Professor Al Weimer’s team received national poster awards at the 2024 American Institute of Chemical Engineers (AIChE) annual meeting, held Oct. 28-31 in San Diego.

Hermann Klein-Hessling Barrientos, a chemical engineering senior, and Jessica Connell, a chemical engineering junior, each took home first-place, Barrientos in the "Catalysis and Reaction" category and Connell in "Materials Engineering and Science." Nathan Smith, a chemical engineering senior, took home third place in the "Separations" category.

The achievement places them among top undergraduate researchers in chemical engineering, selected from over 400 presenters and judged by approximately 100 professionals.

"Through focused team meetings, our students are encouraged to delve into the 'why' questions that underlie their research—a critical step for effectively communicating their work and standing out in a competitive setting," said Weimer, a Melvin E. and Virginia M. Clark professor of chemical and biological engineering.

Students are also coached to deliver concise, one-minute presentations, allowing them to present confidently and capture the interest of their audience, he said. PhD mentors assist the undergraduates with the development of their posters, offering support with presentation techniques and strategies to maximize their impact.

Additionally, attending the AIChE meeting also allows undergraduate students to network with professionals and peers, often leading to job offers or graduate school opportunities.

"This exposure opens doors for future career paths," he said.

Over the past 25 years, Weimer has mentored roughly 125 undergraduate students through independent study and internships, with more than 25 of them going on to earn PhDs, MDs or other professional degrees. Each year, he supports undergraduate participation in the AIChE annual meeting with assistance from the Undergraduate Research Opportunities Program (UROP) or the Discovery Learning Apprenticeship Program (DLA).

Weimer's research spans diverse areas of engineering, focusing on particle surface modification by atomic layer deposition and high-temperature chemical reaction engineering using concentrated sunlight.

Professor Hendrik Heinz and his CU Boulder team, along with collaborators from University of California, Los Angeles, achieved a breakthrough that could boost clean energy production. The research was featured on the cover of the journal “Nature Catalysis” in July.

In the study, researchers pinpointed the active sites of tiny platinum-alloy catalysts, which are crucial for making fuel cells more efficient at converting water into energy.

Fuel cells generate electricity through a chemical reaction, typically combining hydrogen with oxygen. Unlike traditional combustion engines, they produce energy without burning fuel, making fuel cells a clean, efficient technology, ideal for powering electric vehicles.

The catalysts accelerate the reactions that convert hydrogen and oxygen into electricity, making the process more efficient and enhancing the overall performance of the fuel cell. Using advanced 3D atomic imaging and machine learning, the study revealed how these catalysts work at an atomic level, providing insights that could help design better catalysts to address global energy challenges.

Cheng Zhu, a postdoctoral associate in the Heinz Group, made significant contributions to the study and recently joined the babyֱ��app at Guangdong Technion - Israel Institute of Technology (GTIIT) in China.

This research was supported by the National Science Foundation's Materials Genome Initiative, (DMREF), including the first Special Creativity Award in the DMREF program. Heinz led the CU Boulder-UCLA team, which has resulted in more than 60 publications, including more than 10 papers in top journals like “Science” and “Nature” and high-level “Nature” journals such as “Nature Catalysis.” The UCLA team included the senior investigators Phillipe Sautet, Yu Huang and Jianwei (John) Miao.
