The kinetic and voltammetric dependencies of the nitriding process were determined. For the individual metals and the weld zone, interaction with nitrogen proceeds via different mechanisms. Pure metals react with nitrogen through the formation of three- and two-layered structures. Nitriding of the weld zone is accompanied by the decomposition of the Zr–V solid solution with segregation of metallic vanadium at grain boundaries as a separate phase. Simultaneously, mutual dissolution occurs between the nitrogen reaction products: nitrogen solid solutions in both metals and their nitrides of varying stoichiometry. The ceramic formation process is accompanied by diffusion of vanadium into the region of its lower concentration and the formation of the intermetallic compound Zr0.3V0.6N0.1, which does not interact with nitrogen at the synthesis temperature. For gradient and ceramic structures (Zr–V)Nx in the temperature range from –195.7 to +550°C, the nature of the dependence of the thermoelectromotive force (thermo-EMF) on nitriding time was established and its magnitude was evaluated. The obtained ceramic and gradient materials can be used as ceramic thermoelectric converters.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"16 5","pages":"1577 - 1586"},"PeriodicalIF":0.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128637","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}

An improvement in the strength, deformation properties, and thermo-oxidative stability of the composites was revealed upon the introduction of fine nickel oxide, which is apparently associated with the formation of interfacial bonds between the nickel-containing nanoparticles and the components of the polymer composition. It was shown that nanocomposites based on a mixture of high-density and low-density polyethylenes, including additives of fine nickel oxide, can be processed by both pressing and methods of injection molding and extrusion, thereby expanding their fields of application. Small amounts of the nanofiller introduced into the polymer act as structure-forming agents, that is, artificial crystallization nuclei, which contributes to the formation of a fine spherulitic structure in the polymer, as characterized by the improved physical–mechanical and thermal properties of the resulting nanocomposite.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"16 5","pages":"1436 - 1440"},"PeriodicalIF":0.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128681","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}

The dependence of the growth rate of silicon NWs in the open chemical system SiCl4–H2 on the molar ratio of the components [SiCl4] and [H2] has been experimentally established. With an increase in the molar ratio [SiCl4]/[H2], the growth rate of NWs passes through a maximum, and at high concentrations of silicon tetrachloride, due to interaction with the gas phase, the etching of surface layers of crystals and the substrate is possible. It is shown that, in contrast to the SiH4–H2 system, the observed extreme behavior of the dependence of the NW growth rate on the composition of the gas phase is due to the reversibility of the chemical reaction between SiCl4 and H2. A direct correlation between the thermal conductivity coefficient of the metal-catalyst and the growth rate of NWs is established. A thermodynamic model of the process, which determines the thermodynamic conditions for the preferential growth of Si NWs by the vapor → liquid → crystal mechanism in relation to crystallization by the vapor → crystal mechanism, is considered. The values of standard changes in molar enthalpy, entropy, and Gibbs energy of some reactions occurring in the chloride-hydrogen process for obtaining silicon NWs are calculated. The range of changes in the gas phase composition for stable growth of NWs at a given growth temperature is determined.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"16 5","pages":"1293 - 1300"},"PeriodicalIF":0.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128765","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}

The method for producing the polymer composite material is based on preparing a latex composition using dispersions of components from the sulfur vulcanizing group and a biofiller, which can be wood flour, coffee pucks, or potato starch. A coagulant composition was selected to ensure the formation of a defect-free latex gel on the mold surfaces during the production of dipped products. Tests measuring the tensile strength of polymer films confirmed the relevance of the developed polymer composite material formulation. It was established that low-filled compositions allow obtaining products with higher strength compared to unfilled ones. Standard methods confirmed the environmental safety of products based on the developed polymer composite material and the absence of toxic effects of their degradation products on the germination and early growth of higher plants. It was found that the decomposition products not only do not negatively affect the growth of higher plants but also promote their development.
