最近研究了镓的宽液态范围，其中将镓用作溶剂，成功地合成了三元硅化物 SmNiSi3 和 YNiSi3，而不用将镓掺入其结构中，这是一种非常有前景的新合成方法。
Gallium (Ga) is a silver-colored metal that exists as a metallic liquid or solid, depending on the ambient temperature, with a melting point of 29.8 °C and a boiling point of 2,403 °C. This unique property allows gallium to be used in various applications, particularly in electronics and optoelectronics. Our high-purity gallium is characterized by its purity of 99.999% on a trace metals basis, it is utilized in the production of semiconductors, LED technology, and solar panels. Additionally, its exceptional thermal and electrical conductivity makes it particularly valuable in electronics and advanced technology applications.

Microbes have evolved elaborate iron-acquisition systems to sequester iron from the host environment using siderophores and heme uptake systems. Gallium(III) is structurally similar to iron(III), except that it cannot be reduced under physiological conditions, therefore gallium has the potential to

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

We demonstrate a very simple and generic protocol for ultrasensitive in-situ label-free detection of DNA hybridization using third generation poly(amidoamine)dendrimer (G3-PAMAM) functionalized GaN nanowires (NWs). PAMAM modified GaN NWs provides large density of docking site to immobilize significant number of
