(Phys.org)—A team of researchers working at the Max Planck Institute for Polymer Research has found through experimentation that friction in sliding drops is similar in some ways to that of solid objects. In their paper ...
Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. Almost 80 years ago, the Dutch physicist Hendrik Kramers predicted ...
