(2003)A new method has been developed to impose different redox conditions in high-temperature-pres-sure experiments in cold-seal pressure vessels, at 800 degrees C and 2000 bars. Experiments were conducted by loading a metallic ...
-
(1998)An automated inlet system has been developed for deuterium/hydrogen isotope analysis of water using on-line reduction to hydrogen. A modified HPLC autosampler introduces precise aliquots of water (0.5 to 5 μl) into a heated ...
-
(2001)Hydrogen isotope investigations on hydrothermal quartz reveal two H-reservoirs: (i) trapped fluid inclusions, and (ii) structurally bound water in homogenously distributed small clusters or bubbles. Varying mixing ratios ...
-
(2005)The solubility and incorporation mechanisms of H and various trivalent and divalent cations in synthetic rutile have been investigated. Experiments performed using different bulk Fe2O3 contents demonstrate that Fe3+ ...
-
(2001)Use of a simple, disposable apparatus allows the measurement of 2H/1H ratios in small quantities of potentially toxic organic materials without the release of hazardous compounds. The apparatus consists of welded nickel ...
-
(2001)Incipient shock-induced devolatilization of Murchison meteorite occurs upon subjecting samples to a minimum shock stress, or pressure, of about 5 GPa. This pressure is similar to that required to initiate devolatilization ...
-
(2003)The effect of pressure upon hydrogen bonding in synthetic end-member clinochlore, (Mg5Al)(Si3Al)O10(OH)8, has been studied in situ by high-pressure micro-Raman spectroscopy in a moissanite-anvil cell to 26.5 GPa at 300 K. ...
-
(1997)Addition of a simple evacuated collection device to nickel-tube pyrolysis bombs permits collection of the hydrogen gas produced during decomposition of water and other substances containing hydrogen. Tests using water ...
