Metal Bellows Type Gas-liquid Phase-change Actuator

A MEMS electrochemical bellows actuator for fluid metering applications.

We present a high efficiency wireless MEMS electrochemical bellows actuator capable of rapid and repeatable delivery of boluses for fluid metering and drug delivery applications. Nafion®-coated Pt electrodes were combined with Parylene bellows filled with DI water to form the electrolysis-based actuator. The performance of actuators with several bellows configurations was compared for a range o...

The nuclear liquid { gas phase

The time evolution of excited nuclei, which are in equilibrium with the surrounding vapour, is investigated. It is shown that the nite nuclear systems undergo a rst order phase transition. The caloric curve is presented for excited 16 O, 24 Mg, 27 Al and 40 Ca and the critical temperature is estimated for 16 O.

Dynamical liquid-gas phase transition

We describe in detail a lattice gas model whose irreversible dynamics leads to a phase transition. Attractive and repulsive forces between particles are similar to those of our previous papers. The equilibrium properties such as the equation of state, the pressure tensor in the bulk and on interfaces, and Laplace's law are investigated numerically. Surface tension, equilibrium
