Excessive nitrogen exported to water bodies affects the balance of ecosystem and poses a threat to human health. Although the concept of water purification service helps quantify nitrogen export, the impact of river transport remains unclear. This study focused on nitrogen as a pollutant by utilizing the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model to assess nitrogen export in the Dongting Lake Basin, taking into account both the processes of sub-basin nitrogen export and river transport.

Regarding the coexistence of heavy metals and organic pollutants, many studies have achieved synergistic removal of Cr(VI) and organic pollutants under acidic conditions. However, the role of Cr(VI) in the removal of organic pollutants under neutral conditions may have been overlooked. Here, the catalytic effect of Cr(VI) in promoting the photoelectrocatalytic degradation of organic pollutants was investigated using a ternary system, which was a combination of photocatalysis, electrocatalysis and Cr(VI) catalysis.

Soil organic carbon (SOC) plays a critical role in mitigating climate change. Conceptualizing SOC into particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) helps us more accurately predict the responses of organic carbon, with varying chemical composition, molecular size, and degree of association with soil minerals, to environmental changes. To assess the controlling factors of particulate organic carbon (POC) and mineral-associated organic carbon (MAOC), plant and soil samples were collected from 54 temperate grassland sites in Northern China, and the impacts of climate, plants, soil properties and microorganisms on POC and MAOC contents were analyzed.

Multifunctional organic light-emitting transistors (OLETs), which combine electric-switching and light-producing capabilities into a single device, are attracting increasing interest as promising candidates for new-generation display technology. Despite advancements in the design of organic luminescent materials and the optimization of device geometry configurations, maintaining operating voltage low while enhancing optical performances remains a key challenge in horizontally structured OLETs. Here, a simple and effective interfacial engineering strategy is employed to improve the optical properties of horizontal OLETs operating at low voltage, by introducing ultraviolet ozone (UVO)-induced surface modification on high-k dielectrics.

Chiral rhenium(I) emitters showing circularly polarized phosphorescence (CPP) are an attractive mainstay for CP organic light-emitting diodes (CP-OLEDs). However, the efficiency of such emitters is not ideal, and they have never been explored for circularly polarized electroluminescence (CPEL) applications. Here, we have tailored robust chiral Re(I) complexes with improved CPP properties, and firstly demonstrated CPEL from rhenium emitters.

Numerous antibiotics have been detected in aquatic ecosystems and induced severe toxic effects on aquatic organisms. However, mechanisms of bioaccumulation and trophic transfer of antibiotics are not adequately discussed, to the best of our knowledge. In this context, the bidirectional selective effect values (BSEV) and trophic transfer efficiency ratio (TTER) of 24 antibiotics in a simulated food chain (Chlorella sorokiniana-Daphnia magna-Danio rerio) were first calculated to mirror the bioaccumulation and biomagnification.

Co-landfill of municipal solid waste (MSW) and bottom ash (BA) has accelerated the scaling of the leachate collection systems (LCS). The matrix of biofilm formation and mineral deposition makes the scaling process in LCS more complicated. However, the fate of metals released from BA and the role of microorganisms in the leachate, which determine the chemical and biological scaling, are not well understood; the scale adsorption ability is little discussed.

The immunosuppressive tumor microenvironment represents a key challenge for chimeric antigen receptor (CAR) T cells in solid tumors and includes the production of the inhibitory cytokine transforming growth factor-β (TGF-β), which limits CAR-T-cell persistence and function. Current strategies involving the blockade of TGF-β signaling have little benefit for solid tumor treatment. Here, we demonstrate a novel inverted cytokine receptor (ICR)-modified CAR-T-cell strategy not only TGF-β signal blockade but also antitumor efficacy enhancement.

Aqueous Zn-ion batteries (AZIBs) are widely acknowledged as viable future energy storage solutions, particularly for low-cost stationary applications. However, the interfacial instability of zinc anodes represents a major challenge to the commercial potential of Zn-ion systems, promoting an array of side reactions including spontaneous corrosion, hydrogen evolution, and dendrite growth that destabilize cell performance, lower Coulombic efficiency (CE) and ultimately lead to early cell failure. While other commercially relevant battery systems benefit from a spontaneously forming solid electrolyte interphase (SEI), no such layer forms in AZIBs.

We have effectively utilized cost-effective 2-bromoanthraquinone as a photocatalyst to develop an efficient and environmentally friendly method for producing -hydroxy lactones under mild visible light irradiation. Importantly, this protocol only relies on oxygen as an oxidant, completely eliminating the need for additional chemical reagents and showcasing a sustainable approach to chemical transformation. Operating at room temperature, we utilized a mixed solvent system of DMF and CHCl, which greatly facilitated the selective conversion of various 2-vinylbenzoic acids and carboxylic acids to functional -hydroxyl lactones.

Organic semiconductor single crystals (OSSCs) have garnered considerable attention because of their high charge mobility and atomic-scale smooth surface. However, their large-size high-quality preparation remains challenging due to the inevitable defects and limited growth speed brought by traditional epitaxial growth. Here, we demonstrate a space-confined strategy, named out-of-plane microspacing in-air sublimation (OPMAS), for growing vertically millimeter-sized OSSCs in several minutes by revolutionizing the heterogeneous epitaxial growth mode severely depending on substrates into a spontaneous homogeneous growth mode free from substrates.
