3 He was originally touted as the better gas for hyperpolarized gas MRI because it is more polarizable and has no effects on the body. [1] However, 3 He is mostly produced by the beta decay of tritium (3 H), which is a product of nuclear warhead production. Additionally, 3 He is widely used by the U.S. military to detect smuggled plutonium. [14]
Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
Biosensors International also licenses its proprietary drug-eluting stent technologies to other medical device companies and specialty stent providers, including Terumo, Devax, Inc., and Xtent, Inc. Biosensors International Group has a joint-venture in Hong Kong listed as Shandong Weigao to market and distribute coronary stents in China. [1]
Jupiter's atmosphere has 2.5 ± 0.5 times the solar abundance values for Xenon and similarly elevated argon and krypton (2.1 ± 0.5 and 2.7 ± 0.5 times solar values separately). These signals of enrichment are due to these elements coming to Jupiter in very cold (T<30K) icy planetesimals. [53]
Because of its scarcity, xenon is much more expensive than the lighter noble gases—approximate prices for the purchase of small quantities in Europe in 1999 were 10 €/L (=~€1.7/g) for xenon, 1 €/L (=~€0.27/g) for krypton, and 0.20 €/L (=~€0.22/g) for neon, [67] while the much more plentiful argon, which makes up over 1% by volume ...
[3] [17] Paper microfluidics have been applied in paper electrophoresis and immunoassays, the most notable being the commercialized pregnancy test, ClearBlue. [3] Advantages of using paper for microfluidics and electrophoresis in bio-MEMS include its low cost, biodegradability , and natural wicking action. [ 3 ]
PandaX is located at China Jinping Underground Laboratory (CJPL), the deepest underground laboratory in the world at more than 2,400 metres (1.5 mi) below ground. [2] [7] The depth of the laboratory means the experiment is better shielded from cosmic ray interference than similar detectors, allowing the instrument to be scaled up more easily. [8]
