Dye wastewater contains many harmful substances and is difficult to treat effectively. Traditional treatment methods are often inefficient and economically unsustainable. In contrast, membrane separation technology offers high separation efficiency and environmental benefits, making it a promising approach for water purification. Therefore, in this paper, the hydrophilic modification of PVDF membranes was carried out by adding ZIF-8 and chitosan(CS), and at the same time, the membranes were endowed with the ability of light self-cleaning. ZIF-8, a metal–organic framework (MOF) material, was synthesized using water as the solvent through the reaction of zinc nitrate with 2-methylimidazole. The PVDF membranes were modified by physical co-mingling, and ZIF-8/CS/PVDF composite membranes with different contents of ZIF-8 and CS were prepared by the submerged precipitation phase transition method. The performance test results demonstrated that the composite membranes doped with ZIF-8 and CS exhibited significant improvements in water contact angle, pure water flux, and dye wastewater treatment performance. Notably, the modified membranes showed exceptional dye removal efficiency and enhanced resistance to membrane fouling. Furthermore, the results of photocatalytic self-cleaning experiments revealed that the modified membranes effectively degraded Congo red and methylene blue dyes under Xenon lamp irradiation, highlighting their excellent photocatalytic self-cleaning capability. These findings suggest that the ZIF-8/CS/PVDF-modified membrane holds great potential for water treatment and self-cleaning applications, achieving up to 93.06% dye rejection and a pure water flux of 95.89 L m<sup>−2</sup> h<sup>−1</sup>, more than double that of the pristine PVDF membrane.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19657 - 19674"},"PeriodicalIF":3.9,"publicationDate":"2025-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current era of escalating antibiotic resistance, the development of novel and efficacious materials for SSI management has emerged as a critical focus in the realms of materials science and biomedical engineering. This study presents the design and evaluation of multifunctional intelligent nanoparticles that integrate both diagnostic and therapeutic capabilities, using a pH-responsive Rhodamine B fluorescent probe as the signal sensing molecule. Under normal conditions, Rhodamine B is quenched due to the closed spirolactam structure. During bacterial infection, the local acidic environment opens the spirolactam ring, forming a positively charged open-ring structure, and the probe emits a fluorescent signal to warn of bacterial infection. Meanwhile, the vancomycin endows the intelligent nanoparticles with antibacterial functionality. Through a comprehensive series of in vitro assays and in vivo animal experiments, the developed intelligent nanoparticles have demonstrated sensitive responses to bacterial infections, providing timely infection warnings and exhibiting autonomous antibacterial action. MSN@V@R demonstrates strong diagnostic and therapeutic potential for bacterial infections. In the SSI model, the fluorescence intensity at the wound site in bacteria-infected mice treated with MSN@V@R was 6.12 fold higher than that of the control group, indicating effective infection detection. Furthermore, MSN@V@R treatment significantly accelerated wound healing, with the healing rate being 19.33% faster than that observed in the untreated group. This innovative approach overcomes the limitations of traditional medical diagnosis and treatment of surgical site infections, offering a promising strategy for early detection and targeted therapy of SSIs.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19728 - 19739"},"PeriodicalIF":3.9,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the corrosion performance, stress corrosion cracking (SCC) susceptibility, and hydrogen uptake of HCP relative to OFE + P under ammonia-disturbed groundwater conditions. Both copper grades were subjected to a 3-month exposure in an autoclave containing simulated groundwater and 100 mg/L of ammonia at room temperature. Constant potentials were applied to shift surface potentials into the Cu₂O/CuO stability region, mimicking thermodynamic conditions associated with SCC. Hydrogen content was assessed by hot-melt mass spectroscopy and thermal desorption spectroscopy supported by molecular dynamics simulations of hydrogen diffusion. U-bend specimens, constantly polarized at − 50 mV versus saturated calomel electrode, were analysed using plasma-focused ion beam (PFIB) and electron backscatter diffraction (EBSD) to characterize microstructural degradation. Both materials presented very-low corrosion rates (0.2–0.4 µm/year), and no hydrogen uptake was detected. However, PFIB and EBSD results revealed fully oxidized, intergranular cracks penetrating up to 10 µm, along random grain boundaries. These shallow features were attributed to ammonia-induced degradation facilitated by localized strain, even under anoxic conditions and room temperature. HCP copper exhibited comparable corrosion behaviour and susceptibility to ammonia-induced intergranular attack to that of OFE + P copper. These results support the potential use of HCP copper as a viable alternative for HLW canisters in ammonia-containing environments.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19977 - 19996"},"PeriodicalIF":3.9,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-025-11571-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among porous materials, metal organic frameworks (MOFs) stand out because of their large surface area, tunable porosity, and structural versatility. This review presents a comprehensive examination of hydrogen storage via the spillover mechanism in palladium integrated MOFs. These adsorbents demonstrate synergistic interactions between metal sites and MOF, contributing to improved hydrogen chemisorption and physisorption through spillover. Particular emphasis is placed on various Pd incorporation techniques, the influence of synthesis methods on spillover efficiency, and the physicochemical factors governing hydrogen uptake. The extent of hydrogen uptake depends strongly on the Pd loading, nanoparticle size, and the nature of the MOF support. Overloading of Pd often results in particle agglomeration, reducing the active surface area and thereby diminishing storage performance. Despite these advancements, challenges remain, particularly in achieving reproducible synthesis, optimizing Pd dispersion, and understanding the kinetics of spillover.

The search begins with a detailed analysis of the well-known parameter Ω, which has already been the subject of studies aimed at maximising it. In line with these theoretical efforts, this paper proposes: (i) a new optimisation strategy, in accordance with the classical definition of a multi-principal-components alloy, (ii) improvements in the calculation of the Ω parameter (through the enthalpy of mixing) and (iii) the definition of a new indicator, which we will call the Λ parameter, which also can be optimised. This new parameter not only takes into account the enthalpy of mixing, but also adds an additional term, the elastic lattice distortion enthalpy, caused by the distortion of the crystal lattice. Both the new maximisation strategy and the new parameter aim to ensure that the high precision of the composition at the maximum does not make it impossible to implement. As a novelty, this paper uses the Excel spreadsheet and its Solver tool for the task of maximisation with constraints, using the evolutionary algorithm. The paper applies the optimisation methods discussed to two multi-component systems that have been widely analysed in the specialised scientific literature, in order to compare all the techniques described. Finally, the article points to the possibility that optimisation of the indicator parameters Ω and Λ could provide the two most stable compositions into which an initially single-phase alloy subjected to high temperature would segregate.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19942 - 19958"},"PeriodicalIF":3.9,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-025-11559-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
