Hydrogen effusion from tritiated amorphous silicon

Hydrogen diffusion in Zr-Pd amorphous alloys

Nuclear Magnetic Relaxation measurements of the dipolar relaxation rate due to hydrogen diffusion in Zr-Pd amorphous alloy~ have been conducted and the results interpreted in terms of the random alloy model. It is found that even though the measured activation

Hydrogen evolution from Zr-based amorphous and quasicrystalline alloys

The combination of local tetrahedral order and favorable chemical composition makes amorphous and quasicrystalline Zr–Cu–Ni–Al alloys good candidates for hydrogen storage applications. Hydrogen evolution from these alloys has been studied by means of thermal desorption spectroscopy (TDS). The characteristics of hydrogen desorption from an initially quasicrystalline phase are analyzed in detail ...

Thermionic Emission from Diamond Films in Molecular Hydrogen Environments

Diamond-based low-work function thermionic electron emitters are in high demand for applications ranging from electron guns and space thrusters to electrical energy converters. A key requirement of such diamond-based electron sources is hydrogen termination of the surfaces which can significantly reduce the emission barrier. However, at high temperatures (≤600°C), terminated hydrogen begins to ...

An Overview of Hydrogen Interaction with Amorphous Alloys

Theories, experimental results and applications associated with hydrogen behavior in amorphous metals and alloys are reviewed. An emphasis is made on the potential use of these advanced materials for hydrogen storage technology. Therefore, several properties that are especially relevant for such applications are assessed. These include structural models for hydrogen occupancy, sorption characte...
