A solution to FIB induced artefact hydrides in Zr alloys

Journal of Nuclear Materials, 2019
The preparation of TEM samples using focused-ion beam (FIB) techniques allows for characterization of electron-transparent site-specific areas, such as oxide-metal interfaces and crack tips, leading to improved understanding of material degradation ...

Hydriding combustion synthesis of Mg2Ni1−Fe hydride

Journal of Alloys and Compounds, 2005
Abstract The hydriding combustion synthesis (HCS) of Mg 2 FeH 6 and Mg 2 Ni 1− x Fe x hydrides was systematically studied by changing the value of x from 0.25 to 1.0. This study aimed at improving the Mg 2 FeH 6 yield in production and examining the effect of the addition of nickel to the hydrogen storage properties of the Mg 2 FeH 6 hydride.

Hydriding and dehydriding kinetics of Dy2Co7 hydride

Journal of Alloys and Compounds, 1999
The rates of hydrogen desorption from the β- and γ-phases of Dy2Co7 hydride, as well as hydrogen absorption into the α- and β-phases were measured and compared. This represents the first time that such comparisons have been made of two-phase transitions within the same intermetallic hydride.

Hydride‐Triel Bonds

Journal of Computational Chemistry, 2018
In this article, we present the results of our comprehensive studies of 72 dimers of thetype (X = Si, Ge; Y = B, Al, Ga; RX = H, Cl, Me; RY = H, F, Cl, Me) and featuring hydride‐triel bonds (i.e., charge‐inverted hydrogen bonds). Influence of X and Y atoms as well as RXand RYsubstituents on various properties of these dimers is investigated in detail ...

Metal Hydride Vibrations: The Trans Effect of the Hydride

Inorganic Chemistry, 2019
trans-Dihydride complexes are important in many homogeneous catalytic processes. Here vibrational spectroscopy and density functional theory (DFT) methods are used for the first time to reveal that 4d and 5d metals transmit more effectively than the 3d metals influence of the ligand trans to the hydride and also couple the motions of the trans-hydrides

Hydrogen storage systems for fuel cells: Comparison between high and low-temperature metal hydrides

International journal of hydrogen energy, 2019
The need for the enhancement of alternative energy sources is increasingly recognised and, in this perspective, the achievement of hydrogen economy seems to be fundamental.
