Albert Liu—2D-Material enabled colloidal electronics

Albert Liu, a PhD candidate in Chemical Engineering, gave the Nano Explorations talk on Tuesday, July 21, 2020.

Graphene and other 2D materials possess desirable mechanical and functional properties for incorporation into or onto novel colloidal particles, potentially granting them unique electronic and optical functions. However, this application has not yet been realized because conventional top-down lithography scales poorly for the production of colloidal solutions.

Liu describes an “autoperforation” technique providing a means of spontaneous assembly for colloidal microparticles comprised of 2D molecular surfaces at scale. Such particles demonstrate remarkable chemical, mechanical and thermal stability. They can function as aerosolizable memristor arrays capable of storing digital information, as well as dispersible and recoverable probes for large-scale collection of chemical information in water and soil.

Nano Explorations is a virtual seminar series powered by MIT.nano that features presentations by MIT students on their work in nanoscience, nanotechnology, and other advanced research fields. The series was launched as a way to keep our nano community connected during the COVID-19 pandemic. Presentations take place on Tuesdays and Thursdays at 11am EST and are open to any interested viewers.
