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".

Biosensors used for screening combinatorial DNA libraries. In a biosensor, the bioreceptor is designed to interact with the specific analyte of interest to produce an effect measurable by the transducer. High selectivity for the analyte among a matrix of other chemical or biological components is a key requirement of the bioreceptor.
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.
Bio-layer interferometry platforms achieve high throughput by utilizing a "Dip and Read" format. [1] The biosensor tips themselves are transported directly to the desired sample and "dipped" into their respective compartment, eliminating the needs for micro-fluidics and the complications (clogging, purification) that come with it.
Canteen Stores Department, Bangladesh (CSD) is a military-affiliated retail chain store in Bangladesh. [ 1 ] [ 2 ] Owned and controlled by the Bangladesh Army , [ 2 ] it provides a variety of food, electronics and other consumer goods. [ 2 ]
The ratio of xenon-136 to xenon-135 (or its decay products) can give hints as to the power history of a given reactor and the absence of xenon-136 is a "fingerprint" for nuclear explosions, as xenon-135 is not produced directly but as a product of successive beta decays and thus it cannot absorb any neutrons in a nuclear explosion which occurs ...
