Nanocomposite structures based on poly-p-xylylene (PPX) nanoparticles with molybdenum oxide exhibit promising memristive properties. Annealing of PPX-based nanocomposite structures after synthesis significantly improves their memristive characteristics, but a detailed study of the effect of annealing temperature on memristive structures has not been conducted. In this paper, the influence of annealing temperature (from 150 to 400°C) on the structural features and electrical properties of the Cu/PPX–MoOx/ITO structure was studied in detail. Thermal annealing at temperatures of 150, 200 and 250°C leads to a gradual compaction of the PPX matrix, which causes a slight increase in resistive switching voltages and a slight decrease in the resistance window, worsens the endurance to cyclic switching and the stability of resistive states, while a decrease in the spread of memristive characteristics is observed. Temperatures of 300°C and above lead to thermal destruction of PPX, and at temperatures above 350°C, crystallization of MoOx occurs. It is found that the optimal annealing temperature for memristive structures is Cu/PPX–MoOx/ITO is in the range of 150–200°C.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"21 3","pages":"445 - 452"},"PeriodicalIF":0.8,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonwoven materials are characterized by size, fiber structure, and surface properties. It has been established that polyamide-6 and polyacrylonitrile are hydrophilic, while polylactide and polystyrene are highly hydrophobic. For all types of nanoparticles, the ability to immobilize throughout the entire volume of polyamide-6 and polyacrylonitrile has been demonstrated, while in the case of using polylactide and polystyrene, the fixation of nanoparticles occurs only in the upper layer of fibers. The surface properties of polymer nanocomposites do not undergo changes during the process of impregnation with biogenic nanoparticles. High antimicrobial activity has been established for polyamide-6 and polyacrylonitrile containing all types of nanoparticles, whereas for nanocomposites based on polylactide and polystyrene, the level of biocidal action was reduced.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"21 3","pages":"406 - 415"},"PeriodicalIF":0.8,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are used either as standalone materials or as components of composite systems incorporating cells and bioactive substances. Because no single material can satisfy all requirements of a biomedical application, composite systems that combine complementary properties of their constituent components are of particular scientific and practical interest. Among natural polymers, silk proteins—silk fibroin and silk sericin—stand out as evolutionarily refined, functionally complementary components of a natural composite. To date, an extensive body of research devoted to both individual silk proteins and composite materials based on them in combination with other biological agents or auxiliary substances of inorganic and organic origin has been published. At the same time, relatively limited attention has been paid to materials based exclusively on the interactions between silk proteins themselves—“silk fibroin/silk sericin” or “silk fibroin/silk fibroin” composites—in various physicochemical forms. This review critically evaluates current strategies for designing silk-protein-based materials and discusses their potential biomedical applications.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"21 3","pages":"327 - 356"},"PeriodicalIF":0.8,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
