DESCRIPTION:Dr Ulrich Lorenz\, Caltech USA\n4D Electron Microscopy combine
 s the spatial resolution of Electron Microscopes with the time resolution 
 of modern laser systems\, opening up exciting possibilities to study dynam
 ics at the nanoscale. In the first part of the talk\, I will present the d
 evelopment of a novel approach to study the material properties of biologi
 cal nanostructures. By impulsively exciting a DNA structure and observing 
 the resulting oscillations\, it is possible to characterize its mechanical
  properties in much the same way mechanical engineers would study a macros
 copic object. In the second part\, I will describe experiments that for th
 e first time allow one to precisely trigger and directly observe liquid fl
 ow in individual nanotubes. A wide range of nanoscale flow phenomena can b
 e observed. In particular\, it is possible to characterize viscous frictio
 n at the nanoscale to address fundamental questions in nanofluidics.
