Amorphous vs Crystalline in Water Oxidation Catalysis: A Case Study of NiFe alloy.

Nano letters (Print), 2020
Catalytic water splitting driven by renewable electricity offers a promising strategy to produce molecular hydrogen, but its efficiency is severely restricted by the sluggish kinetics of the anodic water oxidation reaction.

Compressive mechanical properties of W-particle/Zr-based amorphous alloy composites

Materials Research Express, 2019
In order to study the effect of W-particle on compressive mechanical properties of Zr-based amorphous alloy, Zr-based amorphous alloy composites with the particle size of 100 μm and W-particle volume fraction of 45% were prepared by stainless steel water

Amorphous metallic alloys

Uspekhi Fizicheskih Nauk, 1990
The experimental data on the structure of and the structural defects and structural relaxation in amorphous metallic alloys are reviewed. The elastic and inelastic properties of amorphous metallic alloys and the effect of disorder in the arrangement of atoms on the ferromagnetic properties of amorphous metallic alloys are also studied.

Positron Annihilation in Amorphous Alloys

Physica Status Solidi (a), 1979
The crystallization process of the amorphous Pd0.845Si0.155, Pd0.80Si0.20, and Ni0.81P0.19 alloys is studied by positron annihilation. The following experimental facts are found. 1. In the PdSi alloy, the changes of coincidence peak counts and h-parameters with temperature are consistent with the crystallization mechanism proposed by Masumoto and ...

Relaxation of Amorphous Metallic Alloys

Solid State Phenomena, 1998
Two types of relaxation processes in amorphous alloys have been investigated in metal-metalloid systems. One of them has been studied by measuring the static structure factor S(Q) in cobalt boron glass samples that have been previously isothermally treated on temperatures close to crystallization temperature.

Diffusion mechanisms in amorphous alloys

Materials Science and Engineering, 1988
Abstract A critical analysis of experimental data shows that self-diffusion in relaxed amorphous alloys is controlled by mechanisms involving collective thermal activations. Whereas in FeZr alloys both 59Fe and 95Zr diffuse via direct mechanisms that change with the alloy composition (e.g.

Tracer diffusion in amorphous alloys

Materials Science and Engineering, 1988
Abstract Self-diffusion in various iron-based amorphous metal-metalloid alloys and in amorphous metal-metal systems Fe x Zr 100−x was investigated using radioactive 59 Fe and 95 Zr tracer atoms in combination with ion-beam sputtering for serial sectioning.

Amorphous Semiconductor Alloys

SPIE Proceedings, 1985
Amorphous silicon (a-Si) based alloys have attracted a considerable amount of interest because of their applications in a wide variety of technologies. However, the major effort has concentrated on inexpensive photovoltaic device applications and has moved from a laboratory curiosity in the early 1970's to viable commercial applications in the 1980's ...
