Understanding the differences in community structure, assembly processes, and environmental responses among aquatic multi-trophic communities is essential for effective ecological management but remains limited. To fill this gap, we proposed an ecological management framework integrating key drivers, species interactions, and assembly mechanisms across trophic levels, supported by the statistical methods (VPA, PCA, CCA, RDA, Bioenv, SEM) and ecological models (null model, neutral community model, co-occurrence network) using the Minjiang River as a case study. The results indicated that the impact factors that affected the distribution, dominant species and diversities varied significantly among different communities.

However, it remains unclear whether this process affects the microbial degradation of MPs and pesticides. In this study, 90-day microcosm incubation experiment was conducted using polystyrene (PS), polyethylene (PE), polyethylene terephthalate (PET), polylactic acid (PLA), and atrazine (ATZ).

Due to the differences in land cover and natural surroundings within cities, residents in various regions face different thermal risks. Therefore, this study combined multi-source data to analyze the relationship between urban heat risk and local climate zones (LCZ). We found that in downtown Shenyang, the building-type LCZ was mainly found in urban centers, while the natural- type LCZ was mainly found in suburbs.

Ice application, ankle pump exercise and non-steroidal anti-inflammatory painkillers are the primary clinical treatments after surgery. However, long-term use of non-steroidal anti-inflammatory pain relievers can easily cause gastrointestinal damage.

Urban heat islands (UHIs) and their energy consumption are topics of widespread concern. This study used remote sensing images and building and meteorological data as parameters, with reference to Oke's local climate zone (LCZ), to divide urban areas according to the height and density of buildings and land cover types. While analyzing the heat island intensity, the neural network training method was used to obtain temperature data with good temporal as well as spatial resolution.

Purposefully designing the well-defined catalysts for the selective electroreduction of CO to C H is an extremely important but challenging work. In this work, three crystalline trinuclear copper clusters (Cu -X, X=Cl , Br , NO ) have been designed, containing three active Cu sites with the identical coordination environment and appropriate spatial distance, delivering high selectivity for the electrocatalytic reduction of CO to C H . The highest faradaic efficiency of Cu -X for CO -to-C H conversion can be adjusted from 31.

The exploration of novel systems for the electrochemical CO reduction reaction (CO RR) for the production of hydrocarbons like CH remains a giant challenge. Well-designed electrocatalysts with advantages like proton generation/transferring and intermediate-fixating for efficient CO RR are much preferred yet largely unexplored. In this work, a kind of Cu-porphyrin-based large-scale (≈1.

Metal-organic framework (MOF) based mixed matrix membranes (MMMs) have received significant attention in applications such as gas separation, sensing, and energy storage. However, the mass production of MOF-based MMMs with retained porosity remains a longstanding challenge. Herein, an in situ heat-assisted solvent-evaporation method is described to facilely produce MOF-based MMMs.

Electrochemical CO reduction reaction (CORR) to formate is economically viable considering the energy input and market value. Through learning nature, a series of chloroplast-like porous bismuth-based core-shell (CPBC) materials have been designed. In these materials, the porous carbon can enrich and transfer CO to the core-shell Bi@BiO in CO reduction process, during which BiO layer can be transformed into activated metastable layer to efficiently convert CO into formate and Bi can provide abundant electrons.
