Lithium-sulfur (Li-S) batteries are hindered by the sluggish kinetics of polysulfide conversion and rapid capacity decay. Herein, we report a heterostructured electrocatalyst for addressing polysulfide shuttling and accelerating redox kinetics via self-assembly of cobalt-based metal-organic framework (Co-MOF, CM) nanoparticles onto MXene (MX) nanosheets. The 0D CM acts as catalytic nano-reactors for efficient polysulfide adsorption and bidirectional conversion, while the 2D MXene substrate ensures rapid electron/ion transport and structural stability. The hierarchical architecture, featuring abundant meso/macropores and strong interfacial Co-S/Ti-S interactions, synergistically suppresses polysulfide shuttling and lowers reaction barriers. The optimized CM@MX cathode delivers high-rate capability (1161.5 mAh g −1 at 0.1 C, 314.7 mAh g −1 at 5 C) and cycling stability (63% capacity retention after 250 cycles at 1 C). Mechanistic studies reveal accelerated sulfur redox kinetics enabled by dual-active sites and optimized Li 2 S nucleation/dissolution dynamics. This work provides a scalable heterostructure design paradigm for high-performance Li-S batteries.

Journal of Environmental Chemical Engineering 2025年第4期13卷

作者： Na Luo Zishuo Li Xudong Zhou Sijia Jin Yang Liu Haibo Huang Jidong Dong Dawei Zhang Pengfei Huo Key Laboratory of Bio-based Materials Science & Technology (Northeast Forestry University) Ministry of Education Harbin 150040 China College of Materials Science and Engineering Northeast Forestry University Harbin 150040 China

Rechargeable hydrogel zinc-ion batteries (ZIBs) are considered promising energy storage devices. However, the uncontrollable growth of dendrites, adverse effects at the zinc anode, and inadequate mechanical properties of the gel electrolyte have greatly restricted their practical applications. In this context, the widespread adoption of ZIBs encounters considerable challenges, such as the uncontrolled growth of zinc dendrites, undesirable parasitic reactions at the anode-electrolyte interface, and the limited mechanical strength of traditional gel-based electrolytes. To address these limitations, we have developed a novel multi-network biomass hydrogel electrolyte, called SL-10G-PSAM. This advanced biomass hydrogel incorporates amphiphilic polymer chains rich in hydrophilic and charged functional groups, synergistically combined with the unique helical structure of gelatin. This unique composition plays a crucial role in suppressing unwanted side reactions and encouraging the preferred deposition of zinc along the (002) crystallographic plane, ultimately creating a uniform and smooth zinc anode surface. The combined effects of these mechanisms effectively reduce zinc dendrite formation and lessen parasitic reactions. The SL-10G-PSAM hydrogel displays outstanding properties, including a high ionic conductivity of 10.68 mS cm −1 , an impressive zinc ion transference number of 0.68, and notable mechanical strength of 100 kPa. When used in symmetric Zn||Zn cells, the SL-10G-PSAM electrolyte allows for stable cycling for more than 1065 h. Additionally, the stable Zn negative electrode provided new insights for the Zn anode, achieving 99.04 % over 500 cycles. Furthermore, when incorporated into Zn||MnO 2 full cells, this hydrogel electrolyte enables impressive specific capacity and significantly improved cycling stability. This study presents a novel paradigm for designing advanced biomass hydrogel electrolytes that possess superior mechanical properties and ion transport

Figuring out the effect of Grifola frondosa Polysaccharide (GFP) on gut microbiota is increasingly recognized because of its widespread use in medicine area. In the present study, we investigated the potential influences of GFP with five molecular weight ranges on the gut microbiota, lipid content in serum and livers, and metabolic pathways in mice. GFP with each molecular weight range significantly changed the composition of the gut microbiota. Compared with the control (CK) group, GFP with five molecular weight ranges significantly changed Beta-diversity of the gut microbiota, especially EG3 (30-50k Dalton) group and the EG5 (⩾100k Dalton) group. GFP with five molecular weight ranges had no significant effect on the lipid profiles of the content of triglycerides (TG), total cholesterol (T-CHO), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) in serum. The EG4 (50-100k Dalton) group obviously reduced the content of TG and T-CHO, slightly increased the content of HDL-C, and slightly changed the content of LDL-C in liver. The EG1 (⩽10k Dalton) group, the EG2 (10-30k Dalton) group, the EG3 group and the EG5 group made the KEGG pathways changed. These findings illustrated that GFP positively affected the microbial environment in the gut microbiota and offered the experimental evidence for preparation of multi-functional diet or medicine.

How to intensify nucleation of ultra-wide metastable zone widths: Case study of 4,4′-Oxydianiline

引用

Separation and Purification technology 2025年 375卷

作者： Jiaqi Li Xingyu Zhang Xinmei Lv Shijie Xu Yanfei Wang Tianjin Key Laboratory of Brine Chemical Engineering and Ecological Utilization of Resources Tianjin Engineering Center of Marine Chemical Engineering & Technology Tianjin Key Laboratory of Multiplexed Identification for Port Hazardous Chemicals State Key Laboratory of Bio-based Fiber Materials College of Chemical Engineering and Materials Science Tianjin University of Science and Technology Tianjin 300457 China

Crystallization systems exhibiting ultra-wide metastable zone widths (MSZWs) due to pronounced solute–solvent hydrogen bonding interactions are characterized by impeded de-solvation and aggregation of solute molecules, resulting in nucleation inhibition. In our previous experiment, we found that the MSZW of 4,4′-Oxydianiline (ODA) in N, N-Dimethylacetamide (DMAC) can be as high as 40–50 K. Here, we demonstrate three strategies to shorten the MSZW of ODA in DMAC: elevating saturation temperature, ultrasound-assisted nucleation, and anti-solvent (H 2 O)-regulated cooling crystallization. As expected, elevating saturation temperature can shorten the MSZW and there is a very large shortening under ultrasound-assisted, with a shortening of up to 90 %. More interestingly, anti-solvent (H 2 O)-regulated achieved a remarkable 95 % reduction of MSZW despite lowering solubility. Molecular dynamics simulations revealed that H 2 O introduction promotes solute aggregation by weakening the strong interactions between ODA and DMAC. Furthermore, building upon the validated universality of the Xu-S model, we achieved precise prediction of MSZWs by correlating key nucleation parameters ( γ , A , D , η ) with the nucleation temperature ( T 1 ). To the best of our knowledge, this is the first study to regulate ultra-wide MSZWs via anti-solvent regulated strategy in cooling crystallization. This work will provide new insights into how to enhance nucleation and achieve efficient separation in the ultra-wide MSZWs.

Ltd. Changsha410000 China

The influence of Resin variations in catalytic cracking (FCC) slurry oil on the formation and development of mesophase was investigated in this paper, the approximate molecular structure models of Resin and FCC slurry oil were constructed. The results showed that the aromatic ring skeleton of Resin was dominated by 3-4 ring aromatic hydrocarbons, with a predominance of cata-condensation and complementary peri-condensation. Resin also possessed structural features such as higher residual carbon and thermal stability, higher C/H ratio, aromaticity, N and S content, larger molecular size, longer branched chains, more cyclic alkane structures, methylene bridges, and higher concentration of active sites than FCC-exR. When the Resin was added from 0 to 20 wt%, the effect on the formation and development of the mesophase was relatively weak, while the formation and development of the mesophase were favored with the increase of Resin content when the Resin was added above 20 wt%. In addition, the influence mechanism of Resin on the formation and development of mesophase was revealed from the perspective of chemical reactivity based on the molecular structure characteristics of Resin. This paper has important implications for the regulation of the raw material properties of FCC slurry oil and the preparation of high-quality mesophase pitch. © 2022, The Authors.

Sensitive detection of Staphylococcus aureus enterotoxin B (SEB) is important for preventing food poisoning from threatening human health. In this work, an electrochemical and colorimetric dual-signal detection assay for SEB was developed. A single-atom nanomaterial (Fe-N-C) with peroxidase-like activity was prepared, and AuPt bimetallic nanoparticle–loaded Fe-N-C (AuPt@Fe-N-C) was used as a probe to anchor the secondary antibody (Ab2) of SEB. The dual-signal biosensing strategy for SEB was designed based on the dual-catalytic activity of AuPt@Fe-N-C. First, thiol-β-cyclodextrin-functionalized borophene-coated metal–organic framework with gold nanoparticle nanohybrid (CD/Au@BE@MOF) was loaded on the electrode to enrich the electrochemical molecule, methylene blue (MB). In the presence of SEB, the probe (Ab2/AuPt@Fe-N-C) fixed on the target bound to the primary antibody (Ab1) and triggered catalytic MB degradation, resulting in a weaker electrochemical signal. Furthermore, the probe catalyzed the oxidation of 3,3′,5,5′-tetramethyl biphenyl (TMB) to generate a colorimetric absorbance at 652 nm. Once the target was captured and formed a sandwich-like complex, the color changed from colorless to blue. SEB detection by colorimetric and electrochemical methods showed a linear relationship in the concentration ranges of 0.0002–10 and 0.0005–10 ng mL −1 , respectively, with limits of detection of 0.067 and 0.167 pg mL −1 , respectively. The dual-signal biosensor was successfully used to detect SEB in milk and water samples and has great potential in toxin detection in food and the environment. © 2022, The Authors.
