Sentences with phrase «as krypton»

These experiments suggest that the clustering with selected rare gas carrier atoms (such as krypton and xenon but not argon) can selectively quench N - H bond fission.

For example, they want to measure the planet's inventory of stable noble gases, such as xenon and krypton, which change little in abundance over billions of years and hold clues to planetary origins.

9 But when argon was discovered in 1894, it didn't fit into any of Mendeleyev's columns, so he denied its existence — as he did for helium, neon, krypton, xenon, and radon.

Previously we have been doing experiments at our beamline using other much heavier, and therefore easily detectable, noble gases such as xenon and krypton.

There's no Superman, and there's no such thing as kryptonite, either — at least not one that glows green and contains the element krypton.

The knowledge gained from such research could inform the design, selection, and improvement of adsorbent materials and membranes for capturing gases such as radioactive krypton and xenon generated by nuclear power plants.

If the ionization states of silicon can not only be sampled on such a short time scale, but can also be set — as the first experiments with krypton suggest — scientists might one day be able to use this to develop novel and even faster computer technologies.

Weiss had to distill, heat and pass the air samples over adsorbents to remove gases such as carbon dioxide and krypton that could foul the extremely sensitive detector.

Krypton in today's atmosphere is somewhat heavier than solar krypton, and the krypton embedded in meteorites known as carbonaceous chondrites is even heavier than that.

The prevalences and isotope ratios of the noble, or inert, gases, such as neon, argon, krypton and xenon, provide a valuable tracer of ancient processes, because they are chemically nonreactive and so do not change much over time.

«And the diagnostic clue is that all of the isotope ratios for neon, argon, krypton, xenon, nitrogen, what have you, look as if they have suffered an escape process in which the lightest isotope escaped preferentially relative to the heavier ones» — a process called fractionation.

Inert gases such as neon (Ne), helium (He), and krypton (Kr) and other constituents such as nitrogen oxides, compounds of sulfur, and compounds of ozone are found in lesser amounts.

Thallapally, working with Maciej Haranczyk and Berend Smit of Lawrence Berkeley National Laboratory and others, has been studying materials called metal - organic frameworks, also known as MOFs, that could potentially trap xenon and krypton without having to use cryogenics.

Initial case studies include the accurate calculation of the excited states of pyrrole and its complexes with rare gas atoms (such as argon, krypton and xenon) to explain the qualitatively different results obtained during photofragment slice imaging experiments performed at IESL.

A few of those gases (basically the noble gases: argon, krypton, neon, and xenon) had the same relative abundances as those found in Mars» atmosphere in 1976.

It has been suggested that the rise in CO2 had to come from the Southern Ocean (as seen in higher krypton and xenon values in the atmosphere (Severinghaus et al. 2009, Southern see - saw seen.
