Main characteristics and effectiveness analysis of potential helium source rocks in crust-source helium-rich natural gas reservoirs

Journal of Natural Gas Geoscience
The evaluation of potential helium source rocks’ effectiveness is a core issue in the field of helium resource exploration and development. However, previous studies predominantly rely on uranium (U) and thorium (T) contents and the age of the rock for evaluating the effectiveness of potential helium source rocks, which fails to fully characterize the ...

Combustion and Pyrolysis EA-IRMS Techniques to Determine the δ²H of Diamonds. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Electrochemical CO2 Reduction on a Bi–Sn Eutectic Alloy in Acidic Media for Formic Acid Production [PDF]

ChemSusChem
Acidic CO2 electrolysis enables direct formic acid production with minimal (bi)carbonate formation. A eutectic Bi–Sn gas‐diffusion electrode achieves 81.3% faradaic efficiency (FE) at −100 mA cm−2 and pH 3, retaining selectivity up to −400 mA cm−2 and stable operation for 100 h with < 10% FE loss.
