Probing nanoscale solids at thermal extremes.
We report a novel nanoscale thermal platform compatible with extreme temperature operation and real-time high-resolution transmission electron microscopy. Applied to multiwall carbon nanotubes, we find atomic-scale stability to 3200 K, demonstrating that carbon nanotubes are more robust than graphite or diamond. Even at these thermal extremes, nanotubes maintain 10% of their peak thermal conduc...
متن کاملAttosecond nanoscale near-field sampling
The promise of ultrafast light-field-driven electronic nanocircuits has stimulated the development of the new research field of attosecond nanophysics. An essential prerequisite for advancing this new area is the ability to characterize optical near fields from light interaction with nanostructures, with sub-cycle resolution. Here we experimentally demonstrate attosecond near-field retrieval fo...
متن کاملNanoscale hydrodynamics in the cell: balancing motorized transport with diffusion.
One of the central problems in the cell is how to transport molecules around the cell to desired locations. Since low Reynolds number conditions apply and diffusional times are large, without the aid of molecular motors to transport the fluid quickly cells could not survive, yet diffusion is still essential for the ultimate delivery of the goods. This paradox of low Reynolds numberlarge Peclet ...
متن کاملHeat transfer across the interface between nanoscale solids and gas.
When solid materials and devices scale down in size, heat transfer from the active region to the gas environment becomes increasingly significant. We show that the heat transfer coefficient across the solid-gas interface behaves very differently when the size of the solid is reduced to the nanoscale, such as that of a single nanowire. Unlike for macroscopic solids, the coefficient is strongly p...
متن کاملFlow of Fluids and Solids at the Nanoscale
The Hagen-Poiseuille equation of classical fluid flow that assumes a no-slip condition at the wall cannot explain the dramatic increase in flow found in nanochannels. Even if slip is assumed at the wall, the calculated sliplengths are found exceed the typical slip on non-wetting surfaces by 2 to 3 orders of magnitude. Similarly, MD simulations of nanochannel flow cannot explain the flow enhance...
