Published in 2018 at "Geochimica et Cosmochimica Acta"

DOI: 10.1016/j.gca.2017.10.029

Abstract: Abstract Authigenic carbonates are one type of conspicuous manifestation in seep environments that can provide long-term archives of past seepage activity and methane cycling in the oceans. Comprehensive investigations of the microbial community functional structure… read more here.

Published in 2019 at "Tetrahedron Letters"

DOI: 10.1016/j.tetlet.2019.151203

Abstract: Abstract Preparation of mixed carbonates proceeded in one step from ketones and aldehydes via treatment with NaBH4 in dimethyl or diethyl carbonate solvent at elevated temperatures. This is an efficient and convenient alternative to the… read more here.

Published in 2022 at "Faraday discussions"

DOI: 10.1039/d1fd00078k

Abstract: In experimental studies, heavy water (D2O) is employed, e.g., so as to shift the spectroscopic solvent background, but any potential effects of this solvent exchange on reaction pathways are often neglected. While the important role… read more here.

Published in 2022 at "Nanoscale"

DOI: 10.1039/d2nr01834a

Abstract: Scalable efforts to remove anthropogenic CO2via the formation of durable carbonates require us to harness siliceous nanoporous geologic materials for carbon storage. While calcium carbonate formation has been extensively reported in bulk fluids, there is… read more here.

Published in 2023 at "National Science Review"

DOI: 10.1093/nsr/nwac293

Abstract: Electrostatic discharge experiments under simulated martian atmospheric conditions indicate that atmospheric CO2 has been sequestered into carbonate by the Mars dust activities during the Amazonia era. read more here.
