Examining the influence of port ship activities on pollutant emissions in port environments.

There is a direct and close relationship between ship emissions in port waters and the operational status of the ships. Precisely identifying the operational status of ships in port waters and thoroughly exploring the specific relationship between these activities and ship emissions is crucial for achieving accurate control and scientific reduction of emissions from ships in port areas. With advancements in technology, AIS data can accurately capture the operational status of ships, facilitating a macro-level analysis of ship behavior and emission characteristics.

Photocatalytic CO reduction of Ag/AgS/TiCT heterojunctions with enhanced interfacial charge transfer.

Photocatalytic reduction of CO to produce organic fuels is a promising strategy for addressing carbon reduction and energy scarcity. Transition metal carbides (TiCT ) are of particular interest due to their unique layered structures and excellent electrical conductivity. However, the practical application of TiCT is limited by the poor separation efficiency of photogenerated charge carriers and the low migration ability of photogenerated electrons.

Colloids fractionation and characterization of arsenic (As) and dissolved organic matter (DOM) in surface water around a closed arsenic mine.

The speciation and mobility of arsenic (As) in waters are largely influenced by the colloids; however, the impacts of colloids with different molecular weights (MWs) in water fractions remain largely unknown. Herein, the surface water was fractionated into three colloidal fractions and truly dissolved fraction via cross-flow ultrafiltration. Total As (As(T)) presented mainly as As(V) and existed primarily in the truly dissolved fraction.

Biomarkers.

Background: Obesity and higher adiposity in midlife are recognized as contributors to Alzheimer disease (AD). Neurodegeneration in AD is at least partly mediated by vascular compromise and brain hypoperfusion. In this study, we aimed to investigate the associations between BMI and abdominal visceral and subcutaneous adipose tissue (VAT, SAT) and brain cerebral blood flow (CBF) in cognitively normal midlife individuals.
