Quantum fluctuations give rise to van der Waals and Casimir forces that dominate the interaction between electrically neutral objects at sub-micron separations. Under the trend of miniaturization, ...

An international research team led by the University of Vienna has succeeded in developing a new method to directly measure partial charges in molecules. The results, now published in Nature, provide ...

Clinging upside down to polished surfaces is simple for geckos, but scientists’ grasp of the underlying forces behind this phenomenal adherence just became murkier. Researchers report that the ...

The amazing ability of some geckos to scale smooth walls and cling to ceilings could be primarily a result of contact electrification. That is the claim of researchers at the University of Waterloo in ...
