Brown Carbon in East Asia: Seasonality, Sources, and Influences on Regional Climate and Air Quality.

Brown carbon (BrC) has been recognized as an important light-absorbing carbonaceous aerosol, yet understanding of its influence on regional climate and air quality has been lacking, mainly due to the ignorance of regional coupled meteorology-chemistry models. Besides, assumptions about its emissions in previous explorations might cause large uncertainties in estimates. Here, we implemented a BrC module into the WRF-Chem model that considers source-dependent absorption and avoids uncertainties caused by assumptions about emission intensities.

Organics electrooxidation coupled hydrogen production has attracted increasing attention due to the low operation voltage. Nevertheless, the spontaneous production of hydrogen coupled with organics valorization remains challenging. Herein, we develop ultrathin Au/Pt twin nanowire (NW) catalysts for both electrochemical glucose oxidation and hydrogen evolution reaction towards a spontaneous hydrogen production system.

Roots absorb water and nutrients from the soil, support the plant's aboveground organs, and detect environmental changes, making them crucial targets for improving crop productivity. Roots are particularly sensitive to soil salinity, a major abiotic stress that poses a serious threat to global agriculture. In response to salt stress, plants suppress root meristem size, thus reducing root growth; however, the mechanisms underlying this growth restriction remain unclear.

Many types of spatiotemporal patterns have been observed under nonequilibrium conditions. Cycling through four or more states can provide specific dynamics, such as the spatial coexistence of multiple phases. However, transient dynamics have only been studied by previous theoretical models, since absorbing transition into a uniform phase covered by a single state occurs in the long-time limit.

Aerosol light absorption has been widely considered as a contributing factor to the worsening of particulate pollution in large urban areas, primarily through its role in stabilizing the planetary boundary layer (PBL). Here, we report that absorption-dominated aerosol-radiation interaction can decrease near-surface fine particulate matter concentrations ([PM]) at a large-scale during wintertime haze events. A "warm bubble" effect by the significant heating rate of absorbing aerosols above the PBL top generates a secondary circulation, enhancing the upward motion (downward motion) and the convergence (divergence) in polluted (relatively clean) areas, with a net effect of lowering near-surface [PM].
