Many studies in the past decade have sought to explore the origin and evolution of water in planetary bodies based on the hydrogen isotopic compositions of apatite. However, no investigation has stud...
A team of scientists, led by the University of Toronto’s Barbara Sherwood Lollar, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth’s surface in rock fracture...
The hydrogen and oxygen isotopic characteristics of precipitation in coastal areas of Japan were explained on the basis of a long period (23 years) observation of hydrogen and oxygen isotopic ratios ...
Characteristics of δ2 H and δ18O in precipitation samples collected at 16- to 17-d intervals at three stations at the northern end of Honshu Island, Japan, were investigated. Rokkasho and Ajigasawa ...
To evaluate the source of sulfur and the extent of seasonal and local characteristics in Seoul’s precipitation chemistry, we measured sulfur, oxygen, and hydrogen isotopic ratios of precipitation. Th...
To elucidate the isotope geochemistry of CH4 production in deep subsurface environments, we investigated the relation between H2 concentration and hydrogen and carbon isotope fractionation by CO2 red...
Caprolactam modified casein(CA-CPL) was prepared by using casein and caprolactam firstly. Caprolactam modified casein/waterborne polyurethane composite (CA-CPL/WPU) was prepared from CA-CPL and WPU. E...
Some strong reflections about 3 to 5 m thick were observed at depths of 25-60 metres below the sea floor using deep-towed, 5 kHz subbottom profiler data in the Turkish shelf and upper slope of the Ea...
Hydrogen isotope ratios were measured on terrigenous alkanes (n-C25 to n-C31) extracted from recent lake surface sediments from the climatically and environmentally distinct basins Qiangyong Glacier L...
Changes in the D/H ratio of sedimentary organic matter (SOM) during thermal maturation have been difficult to interpret because the effects of hydrogen exchange and kinetic fractionations are c...
Some minerals were considered to store hydrogen on the basis of their porous crystal structure. Besides of crystal graphite and zeolite, some natural clay minerals such as palygorskite-sepiolite miner...
Abstract: A synthetic octahedral-site-vacancy-free annite sample and its progressive oxidation, induced by heating in air, were studied by powder X-ray diffraction (pXRD), Mössbauer spectroscopy,...
Two fundamentally different approaches, termed “pointwise” and “peakwise,” are currently used to correct hydrogen isotope ratio monitoring data for the presence of H3 + ion contributions. Consider...
The kinetic of H extraction-incorporation in diopside single-crystals (Ca . Na Cr Mg0 97 0.02 0.01 0.97Fe Si O ) deduced by monitoring OH infrared absorption bands for samples heated from 973 to0.036 ...
Isotopic compositions of carbon-bound hydrogen in individual compounds from eight di€erent organisms were measured using isotope-ratio-monitoring gas chromatography±mass spectrometry. This techn...
