Gamma radiation induces hydrogen absorption by copper in water.
One of the most intricate issues of nuclear power is the long-term safety of repositories for radioactive waste. These repositories can have an impact on future generations for a period of time orders of magnitude longer than any known civilization. Several countries have considered copper as an outer corrosion barrier for canisters containing spent nuclear fuel. Among the many processes that m...
متن کاملHydrogen Bonding in Water
Hydrogen bonding occurs when an atom of hydrogen is attracted by rather strong forces to two atoms instead of only one, so that it may be considered to be acting as a bond between them [99]. Typically hydrogen bonding occurs where the partially positively charged hydrogen atom lies between partially negatively charged oxygen and/or nitrogen atoms, but is also found elsewhere, such as between fl...
متن کاملRobust and highly active copper-based electrocatalyst for hydrogen production at low overpotential in neutral water.
We report here a Cu(0)-based catalyst free of noble metals for the electrocatalytic hydrogen evolution reaction in neutral water with an onset overpotential of only 70 mV. This is the lowest reported value among Cu(0)-based catalysts for the hydrogen evolution reaction in neutral water.
متن کاملPassivation of copper in silicon by hydrogen
The structures and energies of model defects consisting of copper and hydrogen in silicon are calculated using the AIMPRO local-spin-density functional method. For isolated copper atoms, the lowest energy location is at the interstitial site with Td symmetry. Substitutional copper atoms are found to adopt a configuration with D2d symmetry. We conclude that the symmetry is lowered from Td due to...
متن کاملHydrogen bonding in supercritical water
We study the hydrogen bonding structure of water models at supercritical conditions by molecular dynamics to directly compare with recent microstructural data obtained by neutron diffraction with isotopic substitution (NDIS) experiments. We also study the angular dependence of the hydrogenoxygen pair distribution function to gain insight into the hydrogen bonding mechanism in the molecular mode...
