A novel convective flow membraneless microfluidic fuel cell with porous disk electrodes is described. In this fuel cell design, the fuel flows radially outward through a thin disk shaped anode and across a gap to a ring shaped cathode. An oxidant is

A comprehensive study on the relationship between yield strength, relative density and ligament sizes is presented for nanoporous Au foams. Depth-sensing nanoindentation tests were performed on nanoporous foams ranging from 20% to 42% relative densit

Monolithic nanoporous copper was synthesized by dealloying Mn0.7Cu0.3 by two distinct methods: potentiostatically driven dealloying and free corrosion. Both the ligament size and morphology were found to be highly dependent on the dealloying methods

Recent nanomechanical tests on submicron metal columns and wires have revealed a dramatic increase in yield strength with decreasing sample size. Here, we demonstrate that nanoporous metal foams can be envisioned as a three-dimensional network of ult

Here the authors present current issues in understanding the mechanical behavior of nanoporous foams as a new class of high yield strength/low density materials. Gold nanoporous foams are used for a systematic study of mechanical properties since the

Defects introduced into dendritic web silicon during growth have deleterious effects on electrical properties, and in extreme cases can lead to growth termination. This study used transmission X-ray topography and etch pitting techniques to elucidate

In this paper, we describe a new method for creating nanostructures, and demonstrate its use by depositing Au, Ni, and Zn on a SiO2 passivated Si substrate. The method combined the spatial control of electron-beam lithography with the ease of fabrica

This communication reports the development and performance of a membraneless fuel cell that utilizes a convective electrolyte flow orthogonal to the plane of the cell electrodes. The orthogonal flow acts to convect reactants to the electrodes and as
