The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has been conducted in the area of MEMS cooling devices, taking advantage of the increased heat transfer ...

In this study, the basic catalyst layer (CL) structure, consisting of carbon-supported Pt particles (C|Pt) and an ionomer binder, is investigated numerically by using COMSOL. The significance of modeling discrete Pt particles on the carbon support is highlighted by comparing the cell performance results to the case in which the Pt is assumed to be distributed uniformly over the carbon support as ...

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a freestanding flexible substrate such as polyimide would distort unacceptably during even minor temperature excursions ...
