Reversible actuation of a SCA during cycles of exposure to a O 2-H 2 mixture (10:1) and H 2 at room temperature (real time). ![]() "But if you look for direct chemical to mechanical transductions, actually there are very few options." "There are quite good technologies for electrical to mechanical energy transduction, such as the electric motor, and the McEuen and Cohen groups have shown a strategy for doing that on the microscale, with their robots," Abbott said. Eckert Professor of Engineering in Cornell Engineering. Newman Professor of Physical Science, both in the College of Arts and Sciences and David Muller, the Samuel B. Smith School of Chemical and Biomolecular Engineering in Cornell Engineering, along with Itai Cohen, professor of physics, and Paul McEuen, the John A. The project was led by senior author Nicholas Abbott, a Tisch University Professor in the Robert F. '22, and former postdoctoral researcher Qingkun Liu, Ph.D. ![]() The paper's co-lead authors are Nanqi Bao, Ph.D. The group's paper, "Gas-Phase Microactuation Using Kinetically Controlled Surface States of Ultrathin Catalytic Sheets," published May 1 in Proceedings of the National Academy of Sciences. The approach could one day lead to the creation of a new fleet of tiny autonomous devices that can rapidly respond to their chemical environment. ![]()
