Formation of Thiophene under Simulated Volcanic Hydrothermal Conditions on Earth—Implications for Early Life on Extraterrestrial Planets?

Life, 2021
Thiophene was detected on Mars during the Curiosity mission in 2018. The compound was even suggested as a biomarker due to its possible origin from diagenesis or pyrolysis of biological material.

A Density Functional Theory and Microkinetic Study of Acetylene Partial Oxidation on the Perfect and Defective Cu₂O (111) Surface Models

Molecules, 2022
The catalytic removal of C2H2 by Cu2O was studied by investigating the adsorption and partial oxidation mechanism of C2H2 on both perfect (stoichiometric) and CuCUS-defective Cu2O (111) surface models using density functional theory calculations.

Design of carbon supports for metal-catalyzed acetylene hydrochlorination

Nature Communications, 2021
For decades, carbons have been the support of choice in acetylene hydrochlorination, a key industrial process for polyvinyl chloride manufacture. However, no unequivocal design criteria could be established to date, due to the complex interplay between ...

Nitrogen fixation sensitivity related to water use efficiency at reproductive development in soybean

Plant, Soil and Environment, 2020
Soybean [Glycine max (L.) Merr.] nitrogen fixation is sensitive differentially to drought among different genotypes at different growth and development stages, which directly affects soybean yield. Acetylene reduction activity (ARA) response to a gradual

Efficient Trapping of Trace Acetylene from Ethylene in an Ultramicroporous Metal-Organic Framework via Synergistic Effect of High-Density Open Metal Sites and Electronegative Sites.

Angewandte Chemie, 2020
Acetylene removal from ethylene is a crucial step in the production of polymer-grade ethylene, but remains as a daunting challenge due to the similar physicochemical properties between acetylene and ethylene, and is currently met industrially by energy ...

Efficient electrocatalytic acetylene semihydrogenation by electron–rich metal sites in N–heterocyclic carbene metal complexes

Nature Communications, 2021
Electrocatalytic acetylene semihydrogenation is a promising alternative to thermocatalytic acetylene hydrogenation due to its environmental benignity and economic efficiency, but its performance is far below that of the thermocatalytic reaction because ...
