Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

open access: yesAdvanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

open access: yesAngewandte Chemie, EarlyView.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Review of sulfur dioxide to sulfate aerosol chemistry at Kīlauea Volcano, Hawai‘i

open access: yesAtmospheric Environment, 2017
Sulfur dioxide emissions from the Kīlauea Volcano on the island of Hawai‘i and the subsequent formation of sulfate aerosols have caused a public health hazard across the state of Hawai‘i since the volcano began erupting continuously in 1983.

Benefits of Categorizing Noncovalent Bonds Based on Hydrogen, Halogen, Chalcogen, and Pnictogen Bonds

open access: yesAngewandte Chemie, EarlyView.
A terminology for electrophile‐nucleophile interactions based on names that refer to the electrophile group/atom may offer the advantage to be descriptive, consistent, complete, systematic, clear, and, most important, invariant. Likely, a terminology that employs only the terms σ‐hole bond, π‐hole bond, and p‐hole bond may not.
