Hydrogen Storage in VNx-Hy Thin Films

Electrochemically erasable hydrogen-bonded thin films.

We report a new method to trigger the dissolution of hydrogen-bonded layer-by-layer thin films through electrochemical reduction of dissolved oxygen, which raises the local pH.

Achieving Storage Efficiency through Emc Vnx File Deduplication and Compression

This white paper describes VNX File Deduplication and Compression, a feature of EMC VNX that increases the efficiency of storing network-attached storage (NAS) data. This paper outlines the motivation for increased storage efficiency, how VNX File Deduplication and Compression works, the principles and technical architecture behind it, and how it interacts with other VNX features and functions....

Preparation and Hydrogen Absorption/Desorption of Nanoporous Palladium Thin Films

Nanoporous Pd (np-Pd) was prepared by co-sputtering Pd-Ni alloy films onto Si substrates, followed by chemical dealloying with sulfuric acid. X-ray diffractometry and chemical analysis were used to track the extent of dealloying. The np-Pd structure was changed from particle-like to sponge-like by diluting the sulfuric acid etchant. Using suitable precursor alloy composition and dealloying cond...

Pd Nanoparticles and Thin Films for Room Temperature Hydrogen Sensor

We report the application of palladium nanoparticles and thin films for hydrogen sensor. Electrochemically grown palladium particles with spherical shapes deposited on Si substrate and sputter deposited Pd thin films were used to detect hydrogen at room temperature. Grain size dependence of H(2) sensing behavior has been discussed for both types of Pd films. The electrochemically grown Pd nanop...
