Six databases, including PubMed, Lilacs, Scopus, Embase, Science Direct and Google Scholar, were accessed for the search of articles up to May 2024. Five groups of search terms was created. Eligibility criteria included: experimental studies incorporating antimicrobial agents into denture adhesives; evaluating antimicrobial activity; published articles in peer-reviewed journals and in the English language. Of the 20 articles selected, 16 used inorganic materials and 12 different materials were found, which were divided into 3 subgroups. Eleven articles evaluated antimicrobials medicines, including amphotericin B, chlorhexidine, cephalexin, fluconazole, nystatin, clotrimazole and miconazole. Six articles investigated nanomaterials, incorporating silver nanoparticles (AgNPs), zirconium oxide particles and nanoparticles, zinc oxide (ZnO), zinc oxide nanoparticles (ZnONPs), and nanostructured silver vanadate decorated with silver nanoparticles (AgVO₃) into denture adhesives. One study, classified as other, investigated denture adhesives incorporating pre-reacted glass ionomer particles (S-PRG). Only 8 selected articles used organic materials and 20 distinguishable materials were found, divided into 5 subgroups. Organic materials included different formulations of chitosan, antimicrobial peptides, lipids and extracts. One study, classified as other, investigated adhesives containing pyrazole. Based on the findings, the inorganic agents incorporated into denture adhesives can be divided into two main categories: nanomaterials or antimicrobial medicines. The minority of studies incorporated organic agents. All the inorganic agents promoted antimicrobial activity in denture adhesive. The organic agents were also effective, with the exception of grape seed extract, antimicrobial peptides and lipids. Therefore, is possible to increase the benefits promoted by the use of denture adhesives by incorporating antimicrobial agents.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"140 ","pages":"Article 104022"},"PeriodicalIF":3.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738046","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 paper proposes a novel approach to fabricate gradient energy-absorbing structures using adhesive bonded metal plate, which enables rapid fabrication while maintaining energy absorption performance. Mechanical experiments were conducted on adhesive joints to calibrate the constitutive parameters of the adhesive layer and determine the thickness of the adhesive layer and surface treatment conditions. Numerical simulations of the out-of-plane compression and crushing behavior of four adhesive-bonded rectangular tube configurations were carried out to analyze their energy absorption characteristics and structural deformation. Based on the experimentally validated model, the effects of adhesive width ratio and wall thickness of metal plate on the energy absorption for these bonded structures were investigated. Finally, a comparative analysis of the energy absorption performance between adhesive-bonded energy-absorbing structures and traditional gradient-thickness structures was conducted to verify the feasibility and effectiveness of the adhesive-bonded structures. The results indicate that increasing the adhesive width and thickness of metal plate within a certain range can significantly improve energy absorption performance. However, further increases lead to significant degradation in specific energy absorption, along with an elevated risk of adhesive layer failure at the structural ends. In addition, compared to traditional gradient thin-walled structures, the bonded structure shows improvements of 22.50 %, 19.97 %, and 6.37 % in EA, MCF, and SEA, respectively, demonstrating excellent energy absorption performance and great potential for application.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"140 ","pages":"Article 104015"},"PeriodicalIF":3.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680380","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 explores a novel approach to synthesizing bio-resins from diverse lignocellulosic sources: sugarcane bagasse, birch wood, silver cypress wood, and medium-density fiberboard (MDF) waste, using hydrogen chloride gas for acid hydrolysis. The research focused on developing furfural-based resins through a three-stage process: controlled acid hydrolysis, extraction, and oxidative concentration of the feedstock materials. We employed multiple characterization techniques—spectroscopic analysis, thermal testing, and rheological measurements—to evaluate the resins' chemical composition, thermal stability, and viscoelastic behavior. Among all feedstocks tested, bagasse-derived resin demonstrated superior performance, achieving the highest furfural yield (31.6 %) and exhibiting exceptional water resistance and thermal stability. These enhanced properties stemmed from efficient cross-linking and the material's naturally high pentosan content. Birch and MDF-derived resins showed intermediate performance characteristics, while cypress-based resins yielded lower stability and production efficiency, reflecting variations in source material composition. Our findings establish that bio-resins, particularly those derived from agricultural residues like bagasse, represent viable replacements for synthetic resins in industrial applications.
