Release of Adsorbed Krypton and Xenon from Spilled Charcoal

Distillation of Liquid Xenon to Remove Krypton

A high performance distillation system to remove krypton from xenon was constructed, and a purity level of Kr/Xe = ∼ 3 × 10 was achieved. This development is crucial in facilitating high sensitivity low background experiments such as the search for dark matter in the universe.

Field Ion Emission from Adsorbed Films - Hydrogen and Xenon

Use of xenon and krypton for phasing in protein crystallography

Xenon derivatisation is classically performed with hydrophilic additives (e.g. glycerol) to prevent nucleation of ice when the cryoprotectant buffer containing the crystal is flash cooled. The difficulties of obtaining a suitable cryoprotectant buffer, in which crystals are stable for a period of several minutes are, however, rarely reported. Crystals of porcine pancreatic elastase have been us...

New Infrared Laser Lines in Argon, Krypton, and Xenon

Fourteen new infrared laser transitions in Ar, Kr, and Xe ranging from 3.725 to 17.233 pm are reported. All of the Kr laser transitions and all but oneof the Ar and Xe transitions have upper levels in the s or d state: the majority of the transitions satisfy the condition AK = AJ. Identification of a previously observed, unidentified laser line at 5.804 pm in AI is given. Nobel gas lasers are o...

Xenon and krypton separation in a chromatographic column packed with granulated nano NaY zeolite

In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...
