Intermetallic Materials for High-Capacity Hydrogen Storage Systems.

In this article, we provide an overview of hydrogen storage materials, taking our previous results as examples. Towards the end of the paper, we present a case study in order to highlight the effects of substitutional alloying, compositional additives, and nanostructuring on the hydrogen sorption properties of magnesium-based intermetallics. Specifically, partial substitution of Mg by Li and d-elements by p-elements leads to structural changes, inducing disorder and the formation of high-entropy alloys.

Synthesis, crystal structure and hydrogenation properties of MgLiB ( = 1.11, = 0.40).

The ternary magnesium/lithium boride, MgLiB ( = 1.11, = 0.40, idealized formula MgLiB), crystallizes as its own structure type in 422, which is closely related to the structural family comprising α-AlB, BeAlB and tetra-gonal β-boron.

Electronic structure and optical properties of the AgSbS crystal: experimental and DFT studies.

A high-quality AgSbS single crystal was grown by the Bridgman-Stockbarger method and its crystalline structure and homogeneity were investigated. The fundamental absorption edge of AgSbS was studied. The value of the band gap of the studied compound was obtained at the level of 1.

Femtosecond laser-induced nano- and microstructuring of Cu electrodes for CO electroreduction in acetonitrile medium.

The dependency of CO reduction rate in acetonitrile-BuNClO solution on cathodes, which were modified by laser induction of a copper surface, was studied. The topography of laser-induced periodic surface structures (LIPSS) → grooves → spikes was successively formed by a certain number of pulses. It was proved that for a higher number of laser pulses, the surface area of the copper cathode increases and preferred platy orientation of the copper surface on [022] crystallografic direction and larger fluence values increase.

TbNdZnNi (x = 0.5, y = 4.83): a new intermetallic with a maximum disordered structure and its hydrogen storage properties.

The ternary TbNdZnNi (x = 0.5, y = 4.83) disordered phase belongs to the structural family based on the rhombohedral ThZn structure type.
