Summary: Metal-organic frameworks (MOFs) are crystalline materials composed of metallic clusters and organic ligands. However, their poor conductivity, inaccessible pores, and limited stability hinder their applications. To overcome these challenges, MOFs can be integrated with two-dimensional materials to create H2DPMs with versatile properties, expanding the range of potential applications.

Summary: CO2 emissions have increased significantly in recent decades, leading to global warming and climate change. Anthropogenic activities have caused a 50% increase in atmospheric CO2 in less than 200 years, resulting in more frequent and severe climate events such as rainfall, floods, droughts, heat waves, and rising sea levels. Among various CO2 mitigation approaches, porous silica materials have emerged as promising candidates for CO2 capture technologies due to their unique properties and low cost.

Summary: In this study, the electronic and structural properties of cobalt (Co) transition metal doped over the two-dimensional (2D) porous molybdenum disulfide (P-MoS2) surface toward CO2 adsorption were investigated. The results showed that Co decoration on P-MoS2 had three most stable sites for CO2 adsorption, each adsorbing a maximum number of CO2 molecules. The study demonstrated the potential of double-sided Co-decorated P-MoS2 as a thin-layer two-dimensional catalyst for maximizing CO2 capture and storage.

Summary: This study demonstrates the efficient extraction of uranium (U(VI)) using a novel activated biochar (AB) prepared from fish scales. The ABs showed a high adsorption capacity for U(VI), with thermodynamic analysis indicating a spontaneous and endothermic process dominated by chemisorption. AB-750, with a larger specific surface area and higher surface roughness, exhibited better capture efficiency for U(VI). Desorption and reusability studies confirmed the potential long-term use of AB-750. Spectral analysis revealed that carboxyl/amino groups on AB-750 were the main functional groups for immobilizing U(VI).

Summary: In this study, a simple coating method was used to fabricate metal-organic framework (MOF) membranes for the removal of phosphate and antibiotics from water resources. The self-polymerization characteristics of dopamine were utilized to create a polydopamine-lined interface that controlled the growth and morphology of the MOF membranes. The membranes exhibited higher saturation capacities for phosphate and tetracycline compared to traditional crystal preparations, and were capable of selectively removing phosphate and efficiently removing tetracycline.

Summary: The use of nano-zero valence iron (nZVI) synthesized with green tea extracts for heavy metal remediation has gained attention due to its low-cost, environmental safety, reproducibility, and stability. However, the effects of synthesis conditions on the physicochemical properties and suspensibility of nZVI, which are important for high reactivity, have not been fully understood. In this study, the zeta potentials, sedimentation, and lead removal capacity of nZVIs synthesized using green tea extracts were investigated. The results showed that nZVI synthesized using tea extracts extracted at 80℃ exhibited excellent activity and had outstanding suspensibility and reaction activity when synthesized in a volume ratio of 1:1 (tea extraction versus Fe2+ solution). The optimized nZVI successfully prepared had a lead removal capacity of 377.3 mg/g, which was seven times stronger than traditional chemically synthesized nZVI (50.31 mg/g).

Summary: In this study, two dibenzothiophene (DBT)-based small linear compounds, DBT-MOP and DBT-2F-MOP, were designed and synthesized as hole-transport materials (HTMs) for perovskite solar cells. Compared to DBT-2F-MOP, DBT-MOP showed improved hole-transport properties and charge extraction, resulting in a remarkable efficiency of 19.5% in the inverted device. However, the introduction of a fluoride atom near the methoxy group in DBT-2F-MOP decreased the efficiency, possibly due to the crystallization and rugged film morphology affecting the perovskite layer.

Summary: This study constructed a theoretical framework to explore the relationship between diet structure and living environment, using the Qinghai-Tibet Plateau region as the research object. The results showed that the dietary structure of residents in the area evolved from a plant-based diet to a diversified diet, gradually reducing the burden on the living environment. However, compared to the balanced diet model, the study area had increased food carbon emissions and resource utilization. Regions with high meat consumption put more burden on the living environment.

Summary: In recent years, many developing countries have implemented policies that consolidate rural primary schools, close small community schools, and enlarge centralized schools. This has had a negative impact on the accessibility of education, particularly in remote mountainous areas. However, the expansion of road networks has improved school access for people living in far-flung communities. This study analyzes the spatial patterns of primary school accessibility and its predictors in a mountainous county in southwest China, finding that topographic features and the ruggedness of the zone between villages and schools significantly affect accessibility.

Summary: This paper describes a strategy to catalyze in situ C-H oxidation by combining cobalt (Co) single-atom catalysts (SACs) and horseradish peroxidase (HRP). The Co SACs were synthesized using a Co phthalocyanine complex and were found to be strongly correlated to their reactivity. Increasing the calcination temperature improved catalytic activity, with the Co SACs obtained at 800°C showing superior activity in producing H2O2. The in situ production of H2O2 was further coupled with HRP for selective C-H bond oxidation.

Summary: The rational design of heterogeneous interfaces allows for precise adjustment of electronic structure and optimization of electron/ion migration kinetics in energy storage materials. In this study, an iron-based anode material (Fe2O3@TiO2) was introduced with a built-in electric field through well-designed heterostructure, leading to remarkable performance in lithium-ion batteries (LIBs). The heterostructure formed a conventional p-n junction, successfully constructing the built-in electric field and lithium-ion reservoir. The findings emphasize the potential of heterointerface engineering in optimizing electrochemical reaction kinetics for high-performance iron-based anodes for LIBs.

Summary: The removal of phosphate from water is crucial for protecting the ecological environment due to the widespread use of phosphorus fertilizers causing water deterioration. In this study, calcium carbonate-loaded mesoporous SBA-15 nanocomposites with different Ca:Si molar ratios (CaAS-x) were synthesized as effective phosphorus adsorbents. Various characterization techniques were used to examine the structure, morphology, and composition of the nanocomposites. The results showed that increasing the Ca:Si molar ratio improved the phosphate removal capacity, with CaAS-0.55 exhibiting the highest adsorption capacity. The mesoporous CaAS-0.55 nanocomposite demonstrated fast and efficient removal of high concentrations of phosphate in contaminated wastewater.

Summary: The migration of nano zerovalent iron (nZVI) materials to contaminated sites is limited, hindering the in situ remediation of hexavalent chromium (Cr(VI)) pollution. In this study, the transportability of Mo/nZVI@GT materials was improved using green tea extracts and molybdate. The Mo/nZVI@GT showed pronounced size-selective retention in porous media and enhanced Cr(VI) reduction in the presence of phosphate. Tea polyphenols promoted the production of Mo(IV) species, enhancing the conversion of Cr(VI) to Cr2O3. The study elucidated the mechanisms of Cr(VI) reduction and removal and highlighted the potential application of Mo/nZVI@GT composites in efficient in situ remediation of Cr(VI)-contaminated groundwater and soil.
