Published in 2017 at "Mine Water and the Environment"

DOI: 10.1007/s10230-017-0493-x

Abstract: Hydrochemical analysis and Bayesian discrimination were used to identify groundwater sources for multiple aquifers in the Panyi Coal Mine, Anhui, China. The results showed that the Cenozoic top aquifer water were HCO3−Na+K−Ca and HCO3−Na+K−Mg types,… read more here.

Published in 2018 at "Plant and Soil"

DOI: 10.1007/s11104-018-3763-x

Abstract: AimsPrevious studies have shown that pH, rather than calcium (Ca), is the main reason why some Lupinus species are sensitive to nutrient solutions mimicking calcareous soils; however, a hydroponic system is quite different from soil… read more here.

Published in 2019 at "Chemical Geology"

DOI: 10.1016/j.chemgeo.2018.12.012

Abstract: Abstract Here we present novel cave-analogue experiments directly investigating stable carbon and oxygen isotope fractionation between the major involved species of the carbonate system (HCO3−, CO2, CaCO3 and H2O). In these experiments, which were performed… read more here.

Published in 2021 at "Chemosphere"

DOI: 10.1016/j.chemosphere.2021.130499

Abstract: Quantitative insight into the HCO3--dependent degradation kinetics is critical to improve understanding of the UV processes for the most-cost effective application. In this study, we developed a kinetic model to precisely predict the kinetics in… read more here.

Published in 2019 at "Ecotoxicology and environmental safety"

DOI: 10.1016/j.ecoenv.2019.05.041

Abstract: With the continued increase of technological uses of cerium oxide nanoparticles (CeO2 NPs or nanoceria) and their unregulated disposal, the accumulation of nanoceria in the environment is inevitable. Concomitantly, atmospheric carbon dioxide (CO2) levels continue… read more here.

Published in 2020 at "Biochemistry"

DOI: 10.1021/acs.biochem.0c00208.s001

Abstract: The effect of bicarbonate (HCO3–) on photosystem II (PSII) activity was discovered in the 1950s, but only recently have its molecular mechanisms begun to be clarified. Two chemical mechanisms have been proposed. One is for… read more here.
