Nitrogen Oxide Concentrations in Natural Waters on Early Earth

open access: yes, 2019
A key challenge in origins-of-life studies is estimating the abundances of species relevant to the chemical pathways proposed to have contributed to the emergence of life on early Earth.

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, EarlyView.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Cyclodextrin‐Enhanced Photocatalytic Hydrogen Evolution Based on Formate Decomposition With Bio/Metal Catalysts

open access: yesChemistry – A European Journal, EarlyView.
Hydrogen evolution from formate with a hybrid system of enzyme, donor‐acceptor linked photocatalyst‐cyclodextrin complex (Mes‐Acr+‐CD) and platinum nanoparticle is reported. The use of CD as a dispersant for Mes‐Acr+ is a perfect strategy to enhance photocatalytic activity in aqueous solution without deactivation of the enzyme.

Particulate Nitrate Photolysis as a Possible Driver of Rising Tropospheric Ozone

open access: yesGeophysical Research Letters
Tropospheric ozone is an air pollutant and a greenhouse gas whose anthropogenic production is limited principally by the supply of nitrogen oxides (NOx) from combustion. Tropospheric ozone in the northern hemisphere has been rising despite the flattening
