Crystals of high purity germanium are used in detectors for gamma spectroscopy and the search for dark matter. [91] Germanium crystals are also used in X-ray spectrometers for the determination of phosphorus, chlorine and sulfur. [92] Germanium is emerging as an important material for spintronics and spin-based quantum computing applications.
Organic germanium hydrides such as isobutylgermane ((CH 3) 2 CHCH 2 GeH 3) were found to be less hazardous and may be used as a liquid substitute for toxic germane gas in semiconductor applications. Many germanium reactive intermediates are known: germyl free radicals, germylenes (similar to carbenes), and germynes (similar to carbynes).
In ionizing radiation detection physics, a semiconductor detector is a device that uses a semiconductor (usually silicon or germanium) to measure the effect of incident charged particles or photons. Semiconductor detectors find broad application for radiation protection, gamma and X-ray spectrometry, and as particle detectors.
China on Tuesday banned exports to the United States of the critical minerals gallium, germanium and antimony that have widespread military applications, escalating trade tensions the day after ...
Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride.
In agriculture, the use of the Global Positioning System provides benefits in geo-fencing, map-making and surveying. GPS receivers dropped in price over the years, making it more popular for civilian use. With the use of GPS, civilians can produce simple yet highly accurate digitized map without the help of a professional cartographer.
Organogermanium compounds are used in relatively few commercial applications. Isobutylgermane, a volatile colorless liquid, is used in MOVPE (Metalorganic Vapor Phase Epitaxy) in the deposition of Ge semiconductor films. Propagermanium, also known as Ge-132, and spirogermanium are drugs. [citation needed]
Agricultural chemistry embraces the structures and chemical reactions relevant in the production, protection, and use of crops and livestock. Its applied science and technology aspects are directed towards increasing yields and improving quality, which comes with multiple advantages and disadvantages.
