Carbon material is a hot topic in solar evaporation. Due to the widely distributed microorganisms in natural water, biofouling has limited the actual application of solar evaporation material. Although carbon material lacks of nutrition for microbe, it is still vulnerable to biofouling because of the efficient pollutant adsorption property.

Unlabelled: We present the chemical synthesis of polyethyleneimine-conjugated silver sulfide nanoparticles (PEI/AS) utilizing an economical solvothermal synthesis method, aimed at developing effective alternative antibacterial agents. The antibacterial efficacy of the synthesized materials, both with and without the application of near-infrared (NIR) laser irradiation, was evaluated in vitro against two distinct clinically relevant multi-drug-resistant (MDR) uropathogenic strains: and . The bactericidal effects induced by NIR light indicate that the PEI/AS nanoparticles possess an efficiency that is five times greater than that of AgS alone.

Silver deposits have long been considered to form due to the direct precipitation of silver minerals from aqueous fluids, in which the metal is transported as chloride and/or bisulfide complexes. Ultra-high-grade silver ores have silver contents up to tens of weight-percent in the form of silver sulfides and native silver. Ore-forming fluids of most silver deposits, however, typically contain low silver contents of parts per million silver.

Sharing the same photoexcitation process, fluorescence (FL) and photoelectrochemistry (PEC) accomplish optical-optical and optical-electrochemical switches respectively, and are both widely used in diverse fields. However, since FL and PEC are mutually exclusive in principle, it is difficult to obtain intense FL and PEC responses in a system, limiting FL-PEC dual-mode applications. In this study, AgS quantum dots (QDs) and In(OH) nanoblocks (NBs) are simultaneously synthesized by BSA-templated bio-mineralization, and the excited state electrons of AgS/In(OH)@BSA nanocomposites (NCs) are further regulated by a proteolysis process.

Zearalenone (ZEN), a secondary metabolite mycotoxin primarily synthesized by Fusarium species and prevalent in cereal grains, exerts estrogenic effects that could induce reproductive toxicity and teratogenic outcomes. To enhance the precision of ZEN detection, we have developed an innovative photoelectrochemical (PEC) aptamer-based sensor employing in situ growth silver sulfide (AgS) quantum dots-sensitized graphitic carbon nitride/bismuth oxybromide (g-CN/BiOBr) heterojunction. The g-CN/BiOBr composite exhibits robust structural stability and straightforward synthesis.
