Zur Chemie subvalenter Gallium-Verbindungen und von Gallium-Guanidinaten [PDF]

Für die Darstellung von Galliumclustern haben sich subvalente Gallium-Verbindungen als besonders geeignete Ausgangsverbindungen erwiesen. Gallium in der Oxidationsstufe (I) oder (II) neigt jedoch zu Disproportionierungsreaktionen, was den Zugang zu ...

Axial Function Reflects Global Severity in Inherited Ataxias: The Upright Stability Score in Ambulatory Friedreich vs. Spinocerebellar Ataxia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Inherited ataxias are clinically diverse neurodegenerative diseases, complicating the choice of outcome measures for trials. In spinocerebellar ataxia (SCA), regulatory concerns about the Scale for the Assessment and Rating of Ataxia (SARA) caused a shift toward functional SARA (f‐SARA), contributing to pivotal trial failure.

Recovery of Gallium from Corundum Flue Dust by Two-Stage Alkali Leaching, Carbonation, Acid Leaching and Solvent Extraction Process

Metals, 2018
Flue dust generated during the process of manufacturing corundum is a carrier of critical metal gallium. In this study, a process of alkali leaching-carbonation-acid leaching-solvent extraction was developed to recover and enrich gallium from corundum ...

Lithium Polysulfide Interaction with Group III Atoms-Doped Graphene: A Computational Insight

Batteries, 2020
The development of long lifetime Li–S batteries requires new sulfur–carbon based composite materials that are able to suppress the shuttle effect—namely, the migration of soluble lithium polysulfides from the cathode to the anode of the cell. Graphene is

Nanoscale structural evolution of gallium-copper, gallium-zinc, and gallium-bismuth alloys

Journal of Colloid and Interface Science
Liquid metals (LMs) and alloys such as GaCu, GaZn, and GaBi may possess previously unresolved nanoscale structures that govern their physicochemical behaviour. We hypothesise that such structuring is alloy-dependent and thermally sensitive, arising from differences in material properties, growth kinetics, and thermodynamic behaviours, and that the ...

Gallium

, 2013
Gallium is produced primarily as a by-product of alumina production from bauxite ores and, to a much lesser extent, from the smelting and refining of zinc from sphalerite.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Systematics of the allotrope formation in elemental gallium films

Materials Research Express, 2019
Elemental gallium forms unusual allotropes, whose structures all differ distinctly from the close-packing of spheres typical for nearly all elemental metals.
