hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...

States and regions around the US are readying their bids to host centers for hydrogen production, distribution, end uses.

1098-4402= Strained-layer GaAs and strained-superlattice GaAs photocathodes are used at Jefferson Laboratory to create high average current beams of highly spin-polarized electrons. High electron yield, or quantum efficiency (QE), is obtained only when the photocathode surface is atomically clean. For years, exposure to atomic hydrogen or deuterium has been the photocathode cleaning technique e...

Hydrogen has been known as a clean and suitable fuel to replace conventional fossil fuels. One of the common hydrogen production methods is using water electrolysis process. This method produces oxygen as well as hydrogen by ratio of 1:2. The aim of this work is to investigate the effects of inlet air enrichment by adding produced hydrogen and oxygen to an internal combustion engine. For this p...

The kinetics of hydrogen absorption by Pd(ll0) have been measured as a function of impurity sulfur coverage on the metal surface. In contrast to results obtained on the clean surface in which the absorption process was found to be rate-limited by the diffusion of atomic hydrogen into the bulk, submonolayer coverages of sulfur cause the kinetics to become surface dominated with the dissociative ...
