One of the main failure causes in microelectromechanical systems (MEMS) is stiction. Stiction is the adhesion of contacting surfaces due to surface forces. Adhesion force depends on the operating conditions and is influenced by the contact area. In t

We report a general setting in which the thermal conductivity of nanocomposites can be calculated. Interfacial thermal resistance is also considered and no shape assumptions are made. By this method we have found that oblate spheroidal approximation
