Indiana University and Virginia Tech geochemists show experimental verification of key principle
Indiana University Virginia Tech geochemists
2016/3/21
Geochemists at Indiana University and Virginia Tech have developed and demonstrated a technique for assessing the validity of a principle that has long been important in thermodynamics and chemical ki...
Experimental study of rare earth element partitioning between calcite and sodium chloride solution at room temperature and pressure
rare earth elements lanthanide calcite partition coefficient calcium carbonate
2017/4/11
The rare earth element (REE) partition coefficients between calcite and aqueous solution were obtained experimentally
under the conditions of pH, ionic strength and REE concentration level in the par...
Seasonal variation of isoprene basal emission in mature Quercus crispula trees under experimental warming of roots and branches
isoprene biogenic volatile emission Quercus crispula experimental warming
2017/4/11
Isoprene is a reactive volatile organic compound (VOC), the annual global biogenic emissions of which are the largest
of the non-methane VOC. Since isoprene emissions are partly temperature-driven, u...
Molybdenum isotope fractionations observed under anoxic experimental conditions
molybdenum isotopes diagenesis sediments
2017/4/11
Experiments were carried out to determine molybdenum isotope fractionation associated with adsorption to pyrite.
Results show that the Mo isotope composition of the aqueous solution becomes progressi...
Thermochemical reduction of magnesium sulfate by natural gas: Insights from an experimental study
natural gas thermochemical sulfate reduction (TSR) carbon isotope fractionation
2017/4/12
Thermochemical reduction of MgSO4 by natural gas was carried out in the presence of water. Chemical and carbon
isotopic variations were characterized with microcoulometry, gas chromatography, FT-IR, ...
Can pressure promote hydrocarbon generation from organic matter?—New experimental proof
pressure pyrolysis natural gas carbon and hydrogen isotopes
2017/8/9
In order to investigate if pressure can increase the yield of the yield of methane and gaseous hydrocarbon as a whole, both anhydrous and hydrous isothermal pyrolysis experiments were performed on Fus...
