A newly designed optical centrifuge allows scientists to control molecular rotation inside superfluid helium nano-droplets.

(Nanowerk News) For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes — pipes with walls that can be just one atom thick. The ...

But scientists have struggled for decades to accurately calculate the value of friction, which is part of the data used when running coarse-grained simulations, Guenza said. As molecules move through ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

Water rolls on h-BN but encounters friction on graphene. Atomic structure and substrate shape nanoscale movement, guiding advances in coatings and anti-icing surfaces. Researchers found that this ...
