Article Abstract
Understanding the potential-dependent kinetics of photoelectrochemical (PEC) reactions is crucial for advancing the catalytic applications, particularly for water oxidation. This dependency arises because the accumulation of photogenerated charges, directly influenced by the applied potential, fundamentally dictates the intrinsic limitation of slow charge transfer rates. In this study, we investigated the water oxidation on hematite photoanodes with {012} facets exposed, analyzing the reaction kinetics under light and dark conditions. We found a direct correlation between the applied potential and the reaction mechanism, evidenced by a notable transition in the apparent reaction order which shifted from the 2nd- to the 4th- and then to the quasi-4th-order. This observed kinetic transition is specifically linked to the potential-driven changes in the termination and coverage of the surface oxyl intermediates.

Arbuscular mycorrhizal fungi (AMF) play a crucial role in disease control by establishing symbiotic relationships with plant roots. AMF improve salinity tolerance in plants by regulating the Na/K ratio through selective ion transport and mediate osmotic regulation by inducing the accumulation of osmotic-compatible solutes such as glycine betaine and proline to enable plant cells to maintain water content and the metabolic balance. AMF can also activate antioxidant defense responses by stimulating enzymes that protect plant cells from harmful oxidation and pathological infections.

Waterborne viruses have caused outbreaks of related diseases and threaten human health, and advanced oxidation processes (AOPs), as clean and efficient technologies, have received widespread attention for their excellent performance in inactivating viruses. However, heterogeneity in susceptibility of structurally distinct viruses to various reactive oxygen species (ROS) is unclear. This study first measured the heterogeneity in inactivation kinetics and biological mechanisms of four typical viral surrogates (MS2, phi6, phix174, and T4) to various ROS by visible light catalysis.

In the context of the importance of manganese β-diketonates as precursors for the preparation of manganese oxide thin films and nanostructured materials, we report synthetic protocols and pitfalls encountered in the preparation of a family of Mn(ii) complexes of two fluorinated β-diketonates, 1,1,1-trifluoroacetylacetonato- (tfac) and 1,1,1,5,5,5-hexafluoroacetylacetonato- (hfac). The synthetic conditions and crystal structures of six new complexes are reported, including a coordination polymer {K[Mn(tfac)]}, an unusual trinuclear complex Mn(tfac)(OH), and a series of mononuclear complexes with coordinated solvents tetrahydrofuran, 1,2-dimethoxyethane, water, and acetonitrile. The crystal structures of two known Mn(ii) complexes are also reported for completeness.

Arsenic exposure remains a critical global health concern, with growing evidence linking it to significant kidney dysfunction. This review examines the underlying mechanisms of arsenic-induced nephrotoxicity, including oxidative stress, mitochondrial dysfunction, inflammation, and programmed cell death, which collectively contribute to damage in the glomeruli and renal tubules. Chronic exposure is associated with proteinuria, renal impairment, and an increased risk of chronic kidney disease (CKD).

Herein, we report a simple, microwave-assisted and open-air strategy for gram-scale C3-alkylation of indoles, along with an economically viable strategy for epoxide opening followed by α-alkylation, using the [RuCl(bpy){-PhPCHCONCHPPh-}-κ-(,,,,)] complex (hereafter referred to as [PNP-Ru]). This transformation proceeds an alcohol dehydrogenation (oxidation) mechanism, with water being the sole byproduct in both reactions, underscoring the environmentally benign and sustainable nature of the methodology. The protocol efficiently delivers both mono- and bis(indolyl) derivatives in good to excellent yields.
