TL;DR: Electrodes with electrochemical dimensions as small as 10 angstroms have been fabricated and used for electrochemical studies that have enabled the measurement of electron-transfer rate constants, khet, that are two orders of magnitude faster than khet values accessible with any other electrochemical method.

TL;DR: In this article, the improvement of H/sub 2/ evolution from two different types of catalytic p-type photocathode surfaces has been examined, and a comparison of the naked p-Si, the simply platinized, and the (PQ/sup 2 +//sup ///sup +/.)sub n/.nPt(0))/sub surf/ system compared to the same surface directly platinised confirm an important difference in the mechanism of H /sub 2 / evolution catalysis for the two surface catalyst systems.

TL;DR: In this paper, vertically oriented Si wires with diameters of 1.5 µm and lengths of up to 75 µm were grown over areas > 1 cm^2 by photolithographically patterning an oxide buffer layer, followed by vapor-liquid solid growth with either Au or Cu as the growth catalyst.

TL;DR: The following article is an edited transcript based on the plenary presentation given by Nathan S. Lewis (California Institute of Technology) on April 11, 2007, at the Materials Research Society Spring Meeting in San Francisco.
