Because of its linear dependence on length scale, surface tension can be a dominant force for small systems. Properly harnessed, this force is uniquely suited for nanomechanical applications. We have developed a nanoelectromechanical relaxation oscillator with a surface-tension-driven power stroke. The oscillator consists of two liquid metal droplets exchanging mass, and its frequency is directly controlled with a low-level dc electrical voltage.

    Despite its apparent simplicity, spreading of liquid metals at high temperatures has defied description and generalization. Wetting at high temperature is usually accompanied by interdiffusion and chemical reaction, but the forces that drive reactive spreading and the mechanisms that control its...

    A recently developed model of dynamic wetting (Shikhmurzaev [1]) is applied to the spreading of a liquid over a smooth solid surface in the limit of weak viscosity effects. In this model, experimentally observed deviations of the dynamic contact angle from the static one are attributed to...

    A survey of the past literature shows that the studies on liquid�liquid flows have primarily been carried out in pipe diameters of 0.025 m or more and no significant influence of conduit size on flow patterns was reported. An interest is felt in the present work to extend the study to pipe...
