Aluminum nanoparticles (Al NPs), due to their high energy density, are important materials for propulsion systems, material synthesis and hydrogen generation.
The spectrum in (a)–(e) is almost identical with the broadening of peaks in the N H stretch or B H stretch which indicates the material decomposition and hydrogen release.
Two different storage technologies are conventionally used, i.e. hydrogen gas in high-pressure tanks made of steel or composite material, and liquid hydrogen in cryogenic vessels [5].
Numerical simulations were based on a previously developed micro macroscopic coupled model which includes both the proton diffusion in the nickel active material and the hydrogen diffusion in metal-hydride particles.
Water/steam, flowing through the SG tube, reacts with the tube material, producing magnetite and hydrogen.
For Si-based nanostructures, Jose and Datta [11] reported the structures and electronic properties of silicene clusters and Si-substituted benzenes, suggesting that silicene clusters may be a promising material for FET and hydrogen storage.
The experimental isotherms together with literature high pressure hydrogen data were analyzed in order to search for relationships between structural properties of the materials and their hydrogen uptakes.
This chapter is intended to give a pedagogical overview of environmentally assisted cracking (EAC) in metallic materials and covers hydrogen induced cracking, stress corrosion cracking (SCC), liquid metal embrittlement and some issues concerning oxygen embrittlement during high-temperature oxidation.
Added to such fickleness, plutonium is highly reactive with other metals and materials, especially oxygen and hydrogen.
The matrix is mainly sp3 bonded, with about 20 30% sp2 material, and contains 10% hydrogen in the form of sp3 CHx units.
