Stepwise combustion analyses of distinct nitrogen isotopic compositions on Paleoproterozoic organic matter
nitrogen isotopic composition Paleoproterozoic stepwise combustion method kerogen Gunflint Formati
2017/4/11
Nitrogen isotopic analyses were conducted on two kerogenous samples from the Gunflint Formation (ca. 1.9 Ga)
using the stepwise combustion technique to evaluate a potential analytical problem for the...
Argon isotope ratio of the plume-source deduced from high-resolution stepwise crushing extraction
3He/4He 40Ar/36Ar noble gases Loihi mantle plume
2017/8/10
We have carried out noble gas analysis for gases released by a high-resolution stepwise crushing on basaltic glass and olivine separated from a new set of pillow basalts collected form the Loihi seamo...
Quantitatively determining the sources of dune sand is one of the problems necessarily and urgently to be solved in aeolian landforms and desertification research. Based on the granulometr...
An Efficient Synthesis of Substituted 4-Aryl-3-Cyano-2-Amino Thiophenes by a Stepwise Gewald Reaction
Aminothiophenes bromocrotonitriles substituted aminothiophenes
2010/4/20
The title compounds were efficiently synthesised starting from aryl methyl ketones in 3 steps. Knoevenagel condensation of aryl methyl ketones with malononitrile gave the corresponding crotonitriles (...
Stepwise Hydration of High-Quality Synthetic Smectite with Various Cations
Crystalline Swelling Hydration Interlayer Cation Smectite
2011/12/6
Abstract: Smectites synthesized from experiments at 5.5 GPa and 1500癈 are of high quality, crystals are large at >10 祄, and the 2:1 layers may have a homogeneous charge distribution. Smectite was exch...
Radiogenic Argon Released by Stepwise Heating of Glauconite and Illite: The Influence of Composition and Particle Size
Argon Dehydroxylation Glauconite Illite
2011/12/27
Various size fractions of several samples of glauconitic clay and illite were heated stepwise under vacuum for extended periods to: 1) evaluate radiogenic-argon (Ar) yields in relation to composition ...
