Hi everybody,
There will be two open student/postdoc sessions TODAY to meet this week's
Theochem speaker Prof. Kapral who will talk about modeling
chemically-powered nanomotors (see abstract at the bottom). Please feel free
to join us (and also forward this to other potentially interested people):
14:45 - 15:30 in the Karplus meeting area near M039
16:00 - 17:00 in the Division Room (M102)
I hope some people from the Aspuru-Guzik group and from the other theory
groups can make it.
Best
Johannes

Chemically-Powered Nanomotors
Biological systems make frequent use of molecular motors to perform tasks
such as active transport of material in the cell, cell locomotion and
biochemical synthesis. Recently, chemists have fabricated a variety of
synthetic nanomotors that use chemical reactions to effect self propulsion.
Because of their potential applications, such synthetic nanodevices are
being investigated actively. Like their biological counterparts, these
nanomotors operate in the regime where they are subject to strong molecular
fluctuations from the environments in which they move, and their motion is
governed by viscous forces. The first talk will describe recent work on
various types of synthetic nanomotors, the means by which they move and some
of their possible uses. The second talk will focus on chemically-powered
nanodimer motors. In particular the following topics will be considered:
simulations of their dynamics, microscopic mechanisms for their motion, how
to design motors that beat fluctuations, nonomotor efficienecy and their
collective motions.
