Traditional oil–water separation technologies, due to inherent drawbacks such as the potential for secondary pollution and low treatment efficiency, struggle to meet the demands of pollution control. In this context, membrane separation technology has emerged as a leading solution, leveraging its core advantages of high-efficiency separation, low energy consumption, and ease of operation. Among these, polyvinylidene fluoride membrane materials, which combine excellent film-forming properties, thermal and chemical stability, biocompatibility, and cost-effectiveness, have become the mainstream solution in this field. Existing polyvinylidene difluoride (PVDF) fiber membranes suffer from drawbacks such as severe membrane fouling due to hydrophobicity, relatively low permeation flux, insufficient mechanical strength, and poor durability of anti-fouling modifications. This study proposes a novel method for preparing composite membranes. Electrospray coating titanium dioxide (TiO2)/silicon dioxide (SiO2) onto PVDF/titanium dioxide/GO fiber membranes significantly enhances hydrophilicity, fundamentally inhibits scaling, enhances mechanical strength and structural stability, improves permeation flux, and achieves durable anti-fouling performance.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":"1 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, a well-designed in vitro degradation experiment is crucial for providing valuable guidance for subsequent endeavors. This article presents a thorough examination of the in vitro degradation of biodegradable dressings provided by Bayer. A series of experiments were conducted to investigate the mechanisms of in vitro degradation of biodegradable silica gel fibers (SGFs) and to characterize the composition of degradation products. Subsequently, the primary degradation products of SGF were identified as 23 ± 10% ethanol and silicate compounds. In addition, we employed inductively coupled plasma-mass spectrometry to quantify the metal content in the SGF degradation solution. The in vitro degradation experiments also allowed us to identify key substances potentially responsible for cytotoxicity and assess their effects on cell viability. To validate the accuracy of the in vitro degradation results, in vivo degradation studies were performed on SGF materials, and the results from animal models were consistent with those observed during the in vitro degradation tests. This article emphasizes the instructive significance of the in vitro degradation process for understanding and predicting in vivo degradation behavior.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":"1 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular dynamics simulations were employed to calculate solubility parameters, binding energy, mean square displacement, and hydrogen bonding of the three inclusion complexes (ICs). The mixing energy was calculated using Monte Carlo simulations. The smallest difference in solubility parameters was observed between DM-β-CD and Allicin, indicating superior compatibility. DM-β-CD exhibited the highest binding energy and strongest interaction, signifying greater inclusion stability. Fourier transform infrared spectrometry, X-ray diffraction, and differential scanning calorimetry analyses confirmed the successful formation of the three ICs. Phase solubility tests revealed that all three cyclodextrins formed 1:1 IC with Allicin, consistent with the simulated IC model.

In this study, an eco-friendly Z-scheme heterojunction ZnS/CdIn 2 S 4 composite photocatalyst was successfully synthesized through an innovative combination of hydrothermal synthesis and ultrasonic dispersion techniques. Experimental results demonstrated that the optimal ZnS/CdIn 2 S 4 composite with a molar ratio of 2:1 achieved 93% degradation efficiency for methylene blue under visible light irradiation within 3 hours. Multidimensional characterization techniques were employed to elucidate the performance enhancement mechanisms: XPS analysis confirmed strong electronic coupling at the heterointerface, while SEM images revealed ZnS nanoparticles uniformly loaded on layered CdIn 2 S 4 . This synergistic effect originates from the internal electric field formed at the heterojunction interface, which not only shortens the migration distance of photogenerated electrons (<5 nm) but also promotes spatial charge separation through band bending. This research provides new insights for designing efficient and stable Z-scheme photocatalytic systems, demonstrating significant application potential in the treatment of dye-containing wastewater.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":"1 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147887719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key factor affecting the carbon sequestration efficiency of indirect mineralization method is to achieve the efficient selective leaching of Ca from SS. In this paper, the effects of various factors on the Ca leaching process and the leaching mechanism were investigated. The orthogonal experiment results show that the concentration of NH 4 Cl solution and the solid–liquid ratio are the main controlling factors affecting the Ca leaching behavior. Under the optimized conditions of NH 4 Cl concentration of 2 mol/l, reaction time of 90 min, reaction temperature of 70°C, solid–liquid ratio of 1:35 and SS particle size less than 80 μm, the leaching rate of Ca reaches 55.9%. The phase changes during the leaching process of SS indicate that the main phases involved in the leaching reaction are tricalcium silicate (C 3 S) and dicalcium silicate (C 2 S). Besides, it is found that a small amount of monticellite (CaMgSiO 4 ) and calcium magnesium rhodonite (Ca 3 Mg(SiO 4 ) 2 ) are dissolved, while dicalcium ferrite (C 2 F) and RO phase are difficult to dissolve.
