Manipulation of Van der Waals' forces by geometrical parameters in micro-material handling
Published Article === This paper explores the manipulation of Van der Waals' forces by geometrical parameters in a micro-material handling system. It was observed that the flat-flat interactive surfaces exerted the highest intensity of Van der Waals' forces followed by cone-flat, cylinder-...
