The application of metalDorganic frameworks(MOFs) is hindered by several crucial factors, including low photocatalytic efficiency, poor stability and challenges in recycling. In this study, MIL-53(Fe) was grown in situ on a charcoal sponge(CS) with a large surface area,excellent mechanical properties, and high photocatalytic efficiency using a solvothermal method, thus addressing the above-mentioned shortcomings of MOF ***, CS/MIL-53(Fe) has an amazing light-harvesting capacity in the visible range, leading to a significant improvement in the utilization of light. The results of the experiments indicate that CS/MIL-53(Fe) displays a higher photocatalytic activity(87% Cr(VI)) when exposed to visible light than CS(58%) or MIL-53(Fe)(27%),attributing to the increased separation of photogenerated carriers. e-is the main reactive radical and dominates the photocatalytic reduction process, rooting from that e-can reduce Cr(VI) to low-toxicity Cr(III). This study presents a novel method for constructing photocatalysts with large surface areas, superior mechanical characteristics, and enhanced photocatalytic performance. Additionally, it achieves the resource utilization of agricultural and forestry waste.

A series of alumina samples were prepared using β-cyclodextrin as the non-surfactant template. These samples were characterized by XRD, BET and TEM. The results showed that the alumina samples prepared using β-cyclodextrin template had the higher surface areas （124-484 m^2/g）, larger pore volumes （0.7-1.27 mL/g） and more thermal stability than samples prepared without using β-cyclodextrin.

Introduction:Observational studies have revealed an association between waist circumference(WC)and atrial fibrillation(AF).However,it is difficult to infer a causal relationship from observational studies because the observed associations could be confounded by unknown risk ***,the causal role of WC in AF is *** study was designed to investigate the causal association between WC and AF using a two-sample Mendelian randomization(MR)***:In our two-sample MR analysis,the genetic variation used as an instrumental variable for MR was acquired from a genome-wide association study(GWAS)of WC(42 single nucleotide polymorphisms with a genetic significance of P<5×10^(-8)).The data of WC(from the Genetic Investigation of ANthropometric Traits consortium,containing 232,101 participants)and the data of AF(from the European Bioinformatics Institute database,containing 55,114 AF cases and 482,295 controls)were used to assess the causal role of WC on *** different approaches(inverse variance weighted[IVW],MR-Egger,and weighted median regression)were used to ensure that our results more ***:All three MR analyses provided evidence of a positive causal association between high WC and *** WC was suggested to increase the risk of AF based on the IVW method(odds ratio[OR]=1.43,95%confidence interval[CI],1.30-1.58,P=2.51×10^(-13)).The results of MR-Egger and weighted median regression exhibited similar trends(MR-Egger OR=1.40[95%CI,1.08-1.81],P=1.61×10^(-2);weighted median OR=1.39[95%CI,1.21-1.61],P=1.62×10^(-6)).MR-Egger intercepts and funnel plots showed no directional pleiotropic effects between high WC and ***:Our findings suggest that greater WC is associated with an increased risk of *** measures to reduce WC may help prevent the occurrence of AF.
