Materials researchers Saien Xie and Jaehoon Ji have created a super thin semiconductor with light-responsive molecules that change structure when exposed to different wavelengths. These changes alter the semiconductor’s electronic properties, allowing its conductivity and optical response to be programmed, erased, and reprogrammed with light.

This new semiconductor is a step toward building more energy-efficient sensors, optoelectronic devices and computing technologies.

Congratulations to the 12 Princeton Materials Institute faculty who received Innovation Research Grants from Princeton Engineering!

The awards enable engineering faculty members to take their research in bold new directions that address critical issues in technology, health and the environment.

The projects awarded funding are addressing a wide range of problems in materials science, everything from building concrete with lunar materials to constructing circuits with ultrathin materials to studying the dynamics of quantum materials.

Engineers led by Glaucio Paulino found that the hinge that keeps a ketchup cap open also explains how curved, folded shells can hold multiple stable shapes, a discovery that led them to build a robot that shifts shape and moves using magnets alone, no motors required.

Graduate student Kevin Liu, pictured, spearheaded the project.

Their work was published June 15 in the Proceedings of the National Academy of Sciences (PNAS).

Congratulations to Saien Xie on his recent National Science Foundation (NSF) CAREER Award.

Xie received the NSF's most prestigious honor for early-career faculty in recognition of his exceptional leadership in research and education. By uncovering how atomically thin semiconductors form and how their atomic structure determines their properties, Xie is establishing the scientific foundation for designing next-generation materials for advanced electronics, photonics, and quantum technologies. His CAREER project will provide new design principles for creating smaller, more efficient devices with capabilities beyond today's semiconductor technologies.

Cliff Brangwynne has been elected to the National Academy of Sciences, one of the highest honors given to a scientist or engineer in the United States.

Brangwynne was one of eight Princeton professors elected this year. The other seven were Chris Chang, Maria Chudnovsky, Jianqing Fan, Sabine Kastner, Sebastian Seung, Daniel Sigman and Christopher Skinner. This marks the largest number of new academy members from Princeton University in at least a century.

These eight professors are among the 120 new members and 25 international members chosen in recognition of their distinguished and continuing achievements in original research, according to the academy’s announcement.

Established in 1863, the academy now has 2,705 active members and 557 international members, who are nonvoting members of the academy with citizenship outside the United States.

Brangwynne is Princeton’s June K. Wu ’92 Professor of Chemical and Biological Engineering and the director of the Omenn-Darling Bioengineering Institute. He is an associated faculty member in the Princeton Materials Institute.

Brangwynne’s research focuses on teasing apart the fundamental principles behind biological organization, particularly the biomolecular condensates that form inside living cells. Despite having no surrounding cell walls, these tiny organelles contain RNA, proteins and complex processing bodies. His research team is also engineering entirely new kinds of organelles for biomedical applications. Brangwynne joined the Princeton faculty in 2011. He is also a Howard Hughes Medical Institute investigator and the co-director of the seven-week summer physiology course at the Marine Biological Laboratory in Woods Hole, Mass. He holds a Ph.D. from Harvard University and a B.S. from Carnegie Mellon University.

Art meets science!

Last week, PMI's Kai Filsinger led a glassblowing event with the Princeton Center on Science and Technology and the Princeton University Materials Research Society undergraduate chapter.

Students learned about the fascinating properties of glass-how it transforms under heat, the chemistry behind its colors, and the physics that makes it both delicate and strong. Attendees then made their own glass with a professional glassblower!
