Planetary and pre-solar noble gases in meteorites

open access: yesChemie Der Erde, 2014
Noble gases are not rare in the Universe, but they are rare in rocks. As a consequence, it has been possible to identify in detailed analyses a variety of components whose existence is barely visible in other elements: radiogenic and cosmogenic gases ...

Noble Gases

This chapter covers current knowledge of noble gas composition in the Earth's mantle, with particular reference to its heterogeneity. It discusses the evolution of the mantle–atmosphere pair through the study of degassing and regassing of the Earth's mantle. The chapter presents the dynamics of the present and early mantle.

Bombardment of carbon by noble gases

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992
Abstract Carbon is bombarded by 5 keV He, Ne, Ar and Kr at an oblique angle of incidence (65° and 70° to the surface normal). The energy distribution of backscattered and sputtered ions are measured and calculated with the simulation program TRSPTEST.

Noble Gases in Sea Water

Science, 1964
Concentrations of noble gases in samples of sea water obtained at depths to 3437 meters from a Pacific Ocean station were measured by mass spectrometry. An excess of helium, in relation to concentrations of the other noble gases, is attributed to influx of atoms of this gas from the sediments where it is produced by the natural radioactive

The Noble Gases

2014
The last group of elements in the periodic table consists of the noble gases, which have solid phases in the fcc structure at low temperatures. The total energy plots give the fcc as the ground state for all these elements in agreement with experiment. These materials become metallic at large pressures.

The Noble Gases

1987
Excluding 3He, the rare-gas nuclei amenable to NMR investigation are 21Ne, 83Kr, 129Xe, and 131Xe. Of these only Kr and Xe form compounds that are stable under ordinary conditions, and only 129Xe NMR spectra have been observed in chemical environments other than the pure element, although Kr compounds have been characterized by 19F NMR spectroscopy.(1)

Therapeutic Effects of Noble Gases

Journal of Evolutionary Biochemistry and Physiology
Since the last century it has been known that inert gases can cause a range of physiological effects. The biological activity of inert gases is an extremely multifaceted phenomenon. Despite the similarity of most physical and chemical characteristics, they are able to affect many organs and tissues by interacting with a variety of protein targets ...
