The microstructure, chemical bonds and mechanical properties of films were comparatively investigated. The X-ray diffraction (XRD) analysis revealed the presence of TiC and NbC crystallites in films deposited by co-sputtering of Ti/C and Nb/C targets. The peaks of the XRD spectra of the film obtained by co-spattering of the composite Ti+Nb and C targets are located in intermediate region between the corresponding peaks of the Ti-C and Nb-C films. The X-ray photoelectron spectroscopy (XPS) showed that the Ti-C and Nb-C bonds prevail in the deposited Ti-Nb-C films. It was suggested that the Ti-Nb-C films are nanocomposite and consist of the crystallites of the cubic TiC, NbC and TiC-NbC solid solutions surrounded by amorphous carbon-based matrix. The Knoop hardness of the Ti-Nb-C film is highest and reaches 36.8 GPa. The average friction coefficient determined before film delamination was lowest (0.17) in Ti-Nb-C film.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"138 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75971525","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}

This paper proposes a unique method that allows obtaining stable composite materials in which nanosized MoS2 particles are fixed in the pores of SiO2. To obtain nanocomposites with preset morphological characteristics, the method of hydrothermal synthesis is used, followed by modification of the surface of nanoparticles with functional polymers via polymerization initiated from the particle surface. TEM, impedance spectroscopy, and computer simulation of an equivalent electrical schema are used to characterize such materials before and after grafting a functional polymer shell onto their surface. The prospects of using synthesized composites as cathode materials of lithium current sources, as well as the possibility of controlling the structure and size of the inorganic nucleus and a functional polymer shell, are proved. The kinetics and thermodynamics of Li+-intercalation current generation are studied.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"73 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83943537","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}

We report on domain wall transport through coupled bent nanowires, forming networks with multiple data inputs and outputs. Our results show diverse phenomena which have to be taken into account during these dynamic processes, such as domain wall instabilities or interference between converging signals, and suggest possible architectures of nanowire-based logics.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"14 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81058522","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}

Kinetics of hydrolysis of NaBH4 in presence of Ni and Co based catalysts has been characterized and related to the rate of hydrogen generation. Using both amorphous and zeolite supported Ni and Co nanocatalysts leads to a stable generation of hydrogen in wide range of NaBH4 concentrations and results in high extent of its conversion. Both amorphous and zeolite supported Ni and Co allow achieving a fast kinetics of hydrogen evolution, even though synthesized “in situ” amorphous Ni and Co showed a performance which was 25 % superior as compared to the catalysts deposited on zeolite.
