Aplicación

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.
The wide liquid range of gallium was exploited recently when it was used as a solvent for the successful synthesis of ternary silicides, SmNiSi3 and YNiSi3, without incorporating Ga in their structure -- a promising new synthetic method.

Gallium has been the second metal to show activity against malignant tumors in humans soon after the establishment of platinum drugs in routine clinical practice. It has the unique property of inhibiting tumor growth as a simple cation, mainly because

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

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

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

Self-assembled GaN rods were grown on sapphire by metal-organic vapor phase epitaxy using a simple two-step method that relies first on a nitridation step followed by GaN epitaxy. The mask-free rods formed without any additional catalyst. Most of the vertically
