AbstractDespite the eminent importance of metal alkylidene species for organic synthesis and industrial catalytic processes, molecular homoleptic metal methylene compounds [M(CH2)n] as the simplest representatives, have remained elusive. Reports on this topic date back to 1955 when polymeric [Li2(CH2)]n and [Mg(CH2)]n were accessed by pyrolysis of ...

Hydrogen evolution on gallium, indium-gallium and mercury-gallium electrodes
Transactions of the Faraday Society, 1966Measurements of hydrogen overvoltage η have been made using dropping electrodes of gallium; 19.2 mole % In—Ga; and 0.122, 0.36, 1.64, and 99.65 mole % Hg—Ga in 0.100 M HClO4 at temperatures between 30° and 60°C. η increases by 150 mV when 19.2 % In is added to Ga, and by 280 mV when 1.64 % Hg is added to Ga.

Elemental Gallium as a Source of Subvalent Gallium Units in Gallium–Rhodium Clusters
Angewandte Chemie International Edition, 2003Mild reduction with metals: Elemental gallium is used as mild reducing agent for transition-metal halides to generate subvalent GaCl ligands in novel clusters. In the reaction of Ga with [{CpRhCl2}] (Cp=5-1,3-C5H3tBu2), clusters with GaCl ligands and with unprecedented two-coordinate Ga centers in a multicenter-multiple-bonding interaction between two ...

The trivalent gallium cation is capable of inhibiting tumor growth, mainly because of its resemblance to ferric iron. It affects cellular acquisition of iron by binding to transferrin, and it interacts with the iron-dependent enzyme ribonucleotide reductase, resulting in reduced dNTP pools and inhibition of DNA synthesis.

Self‐Diffusion of Gallium in Gallium Arsenide
Journal of The Electrochemical Society, 1981The self‐diffusion of gallium in gallium arsenide has been studied over the temperature range 1100°–1025°C using radiotracer techniques. Gallium arsenide samples were diffused with 72Ga evaporated layers under known pressure of arsenic in sealed capsules. Following diffusion, layers were removed from the surface using anodic oxidation followed by oxide

Zinc and gallium diffusion in gallium antimonide
Physical Review B, 2007Extrinsic diffusion of zinc (Zn) in gallium antimonide (GaSb) under Ga-rich conditions was analyzed on the basis of the kick-out and the dissociative diffusion mechanism. Accurate modeling of the experimental profiles by means of continuum theoretical calculations reveals that Zn diffusion proceeds via singly positively charged Zn interstitials ...

Germanium and Gallium in Sea-Water: Gallium
Nature, 1958LITTLE is kaown of the occurrence of gallium in sea-water. Its presence was first detected by del Campo and Rodeja1. Bardet et al. 2 found it spectrographically, together with thirteen other trace elements, in water samples taken near Roscoff (Brittany). The only quantitative data so far published are due to Noddack and Noddack3, who found 0.5 µgm.

Abstract Gallium-base components can be found in a variety of products ranging from compact disk players to advanced military electronic warfare systems, owing to the factor that it can emit light, has a greater resistance to radiation and operates at faster speeds and higher temperatures.
