Nanotech luminary Robert Prud’homme elected to National Academy of Engineering

Membership in the National Academy of Engineering is widely seen as one of the highest honors in the engineering profession. The 2024 class includes 114 members and 21 international members — researchers from across industry, academia and government.…

Upcycling plastics, sustainable catalysis expert Michele Sarazen wins NSF CAREER Award

The award comes as part of NSF’s Faculty Early Career Development Program that supports junior faculty who exemplify leadership in education and research. It comes with nearly $600,000 in research funding over five years.

We have much to learn from the lungs of other species

As part of her research into how lungs develop before birth, she and an undergraduate mentee found they could measure the effect of a particular chemical on the patterns of lung growth in chicken embryos. They excitedly submitted their work for peer review but were met with a lukewarm response.

“One of the reviewers said that this is…

Reusable and recyclable, this new hydrogel squishes the old version’s environmental impact

With additional testing and development, a novel material developed by Princeton researchers could make existing and emerging applications for hydrogels — such as artificial muscles and soft robots for safe operation around humans — more sustainable and environmentally friendly.

Researchers built a physical model to probe the creative destruction inside cells

A new window into the nitty-gritty mechanical interactions between liquids and fibrous networks in cells should advance understanding on many biomedical fronts. In addition, the findings offer avenues for exploration in materials science toward “soft matter” substances with novel characteristics.

Designing yeasts to make cleaner fuels earns grad student an innovation award at COP28

The event, part of the global climate conference COP28, featured 100 inventions that address environmental and social challenges. Five projects won awards in separate categories, including the Princeton team’s category: Energy, Efficiency and Waste.

While the first…

Grad student wins best poster for work on metal nanoparticles

The American Vacuum Society’s (AVS) Plasma Science and Technology Division gave Hoffenberg the award for his work advancing the process to make these metal nanoparticles more sustainably and with higher purity. The 69th AVS Symposium was held in Portland, Ore. in November.

While metal nanoparticles are increasingly important for high…

Polymer expert Rodney Priestley elected APS Fellow

Priestley has discovered many phenomena within the study of polymers and soft matter, particularly thin films, colloids and the intricately layered class of materials known as nanocomposites — materials that are important to electronics, cosmetics, medicines and other commercial products. He was one of only three 2023 APS Fellows sponsored by the Division of Polymer Physics.

William Russel, groundbreaking engineer, cherished mentor, and tireless dean who championed graduate students, dies at 77

Russel, the Arthur W. Marks ’19 Professor in Chemical Engineering, emeritus, rose to prominence as a specialist in colloids, which are suspensions of tiny particles in fluids, such as smoke or milk. His work, which included one of the classic equations of his field, helped combat pollution and led to improved paints, medicines and adhesives. He…

AIChE names two Princeton researchers to 35 Under 35

Michele Sarazen, assistant professor of chemical and biological engineering, investigates catalysis and green chemistry to address global grand challenges in energy and sustainable manufacturing. She was…
