DESCRIPTION:Title: Mimicking Nature: Controlling Charge\, Heat\, and Spin 
 at Interfaces\n\nAbstract: Many interactions and processes in nature oper
 ate at low energy and with critical energy balance\, enabling repeated cy
 cling and highly efficient transport. Inspired by these processes\, we tr
 y to understand them\, and to replicate them in synthetic systems. The en
 ergies involved are well below those of visible photon energies\; thus\, 
 we predominantly use tunneling spectroscopies and imaging to probe them. 
 If we could replicate such systems in our devices\, we could save most of
  the energy required to run them. If we could mimic biochemical cycling\,
  we could develop efficient recycling at large scales rather than the ext
 remely labor- and energy-intensive processes of today. We look for underl
 ying principles and what we are currently missing in our understanding. T
 wo of the areas we are exploring are spin conservation in chiral molecule
 s and the roles of polarizability in biological\, and now synthetic\, sys
 tems. Taking this perspective has already led to novel discoveries and in
 ventions\, including thermal control with orders of magnitude improvement
 s\, in scale\, speed\, and effect. One of the key advances in nanoscience
  and nanotechnology has been our increasing ability to reach the limits o
 f atomically precise structures. By having developed the “eyes” to see\, 
 to record spectra\, and to measure function at the nanoscale\, we have be
 en able to fabricate structures with precision as well as to understand\n
