The abundance of xenon in the atmosphere of planet Jupiter is unusually high, about 2.6 times that of the Sun. [69] [a] This abundance remains unexplained, but may have been caused by an early and rapid buildup of planetesimals—small, sub-planetary bodies—before the heating of the presolar disk; [70] otherwise, xenon would not have been ...
Compared with solar xenon, Earth's atmospheric Xe is enriched in heavy isotopes by 3 to 4% per atomic mass unit (amu). [18] However, the total abundance of xenon gas is depleted by one order of magnitude relative to other noble gases. [15] The elemental depletion while relative enrichment in heavy isotopes is called the "Xenon paradox".
Xenon-136 is an isotope of xenon that undergoes double beta decay to barium-136 with a very long half-life of 2.11 × 10 21 years, more than 10 orders of magnitude longer than the age of the universe ((13.799 ± 0.021) × 10 9 years). It is being used in the Enriched Xenon Observatory experiment to search for neutrinoless double beta decay.
Hall-effect thrusters are created with crewed mission safety in mind with effort to prevent erosion and damage caused by the accelerated ion particles. A magnetic field and specially designed ceramic shield was created to repel damaging particles and maintain integrity of the thrusters.
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
Xenon is known to function as a metal ligand. In addition to the charged [AuXe 4] 2+, xenon, krypton, and argon all reversibly bind to gaseous M(CO) 5, where M=Cr, Mo, or W. P-block metals also bind noble gases: XeBeO has been observed spectroscopically and both XeBeS and FXeBO are predicted stable. [33]
If you're interested in maintaining your hormonal levels, you might wonder if there are certain foods that kill testosterone. After all, testosterone naturally decreases with age, so it's ...
Xenon has an unexpectedly low abundance in the atmosphere, in what has been called the missing xenon problem; one theory is that the missing xenon may be trapped in minerals inside the Earth's crust. [73] After the discovery of xenon dioxide, research showed that Xe can substitute for Si in quartz. [74]
