Surface Forces related to the Accumulation and Dispersion of Dust due to the Locomotion of a Cantilever

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
Since surface forces prevent micro-machines from moving in the air, there are a lot of difficult problems to be solved concerning the reliability of micro-machines. Surface forces depend strongly on dust and contaminants.

A Simple and Inherent Safe Mechanosynthesis Method for Producing Tin Metal Nanoparticles Dispersions

Chemical Engineering Transactions
A method for the synthesis of Sn nanoparticles (NPs) is presented, whose technique is based on a reagentless comminution process, where bulky Sn metal undergoes a surface abrasion with release of zerovalent metal NPs produced by metal-ceramic balls ...
