Gallium is a chemical element; it has the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [11] gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Elemental gallium is a relatively soft, silvery metal at ...
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
A gallium scan is a type of nuclear medicine test that uses either a gallium-67 (67 Ga) or gallium-68 (68 Ga) radiopharmaceutical to obtain images of a specific type of tissue, or disease state of tissue. Gallium salts like gallium citrate and gallium nitrate may be used. The form of salt is not important, since it is the freely dissolved ...
China's abrupt announcement on Monday of controls from Aug. 1 on exports of some gallium and germanium products, also used in electric vehicles (EVs) and fibre optic cables, has sent companies ...
Gallium (. 68. Ga) gozetotide. Gallium (68Ga) gozetotide or Gallium (68Ga) PSMA-11 sold under the brand name Illuccix among others, is a radiopharmaceutical made of 68 Ga conjugated to prostate-specific membrane antigen (PSMA) targeting ligand, Glu-Urea-Lys (Ahx)-HBED-CC, used for imaging prostate cancer by positron emission tomography (PET).

Nuclear weapon design. The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test. Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate.

Galinstan is a brand name for an alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. [4][5] In scientific literature, galinstan is also used to denote the eutectic alloy of gallium, indium, and tin, which melts at around +11 °C (52 °F). [5] The commercial product Galinstan is ...
