Xenon Xe 129 hyperpolarized, sold under the brand name Xenoview, is a hyperpolarized contrast agent indicated for use with magnetic resonance imaging (MRI) for evaluation of lung ventilation, and approved for people aged twelve years of age and older. [4] [5] It was approved for medical use in the US in December 2022. [6]
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.
The Senate voted along party lines Thursday to confirm Russell Vought as the next head of the Office of Management and Budget despite fierce pushback from Democrats.
Biosensors is a peer-reviewed open-access scientific journal covering various aspects of biosensor technology, analytical chemistry, and biotechnology research. It is published by MDPI and was established in 2011.
In what’s been called a world first, consumers in the UK are now able to buy a pet treat made with lab-grown meat. The treat contains plant-based ingredients and 4% chicken meat cultivated in a ...
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 ...
The first miRNA (lin-4) was detected by Victor Ambros in Caenorhabditis elegans in 1993. [7] The first detection method was Northern blotting (1977), which had low sensitivity.
