By forming these alloys, previously unknown phase fields of multidimensional phase diagrams are explored. The large number of possible substitutions of constituent elements on crystal lattice sites justifies the dominant contribution of mixing entropy over enthalpy to the free energy reduction. This leads to the formation of phases, which otherwise could not be formed in alloys with fewer main alloying elements. Here we explore magnetic and compositional properties of a High-Entropy Alloy, namely FeCoNiAlx Mnx (0.05 ≤ x ≤ 3.08), composed of magnetic (Fe, Co, Ni) and non-magnetic elements (Al, Mn). By magnetic force microscopy of a selected area, it is observed that for intermediate to low Al and Mn contents, the alloy splits in two major crystallographic phases with different magnetic properties. Elemental maps of the same area were recorded with energy dispersive spectroscopy and scanning electron microscopy. Counterintuitively, it was found that the phase rich in non-magnetic Al has stronger magnetism than the phase rich in Fe. This work showcases possible applications of the here presented HEAs as soft magnetic materials in functional magnetic elements.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"17 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":"90217781","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}

Nickel-based thin films were deposited on the surface of nanocellulose by RF magnetron sputtering. The peculiarities of surface morphology and chemical composition of inorganic material on the surface of biopolymer substrate were studied. Flexible strain sensors were obtained from nickel busbars on the surface of nanocellulose. The influence of overall sizes of nickel busbars on piezoresistive parameters of flexible sensors was established. It was determined that the maximum strain sensitivity is observed for a nickel busbar with a width of 1 mm, a thickness of 250 nm, a length of 15 mm and was 195,8⋆ 10-3 %. The magnitude of drift in time was 0,17 %/min. Obtained strain sensors were tested on mechanical strength depending on nickel busbar sizes. It was shown that the presence of nickel thin film increases the strength of strain sensors by 40%: from 13.8 MPa for pure nanocellulose to 19.5-19.6 MPa for nanocellulose with nickel thin films.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"340 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75938349","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 comparative analysis of SAXS and Raman spectroscopy data was done. The obtained materials have a turbostratic structure and consist of the ultrasmall graphitic fragments separated by amorphous carbon. It was determined that the carbonization temperature in a range of 800-1000°C causes sharp increase in micropores relative content after carbon treatment with nitric acid. The minimal lateral size of graphitic crystallites (of about 5.5 nm along (002) basal plane) is observed for nitrogen-doped carbon obtained at carbonization temperature of 800°C that corresponds to average aggregates size. The control of activated carbons structural properties allows to increase energy and power densities of electrochemical capacitors as well as to create the preconditions for composite electrode materials obtaining with predictable properties.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"26 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74725482","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}

It was found that Fe-Ni-Co-Ti alloys in certain intervals exhibit unusual deformation and electrical effects when exposed to temperature and mechanical stresses. The reasons and factors that contribute to the achievement of large superelastic deformations and reactive stresses are analyzed. The appearance of differential thermo-emf (thermo-electromotive force) signals during the induction of martensitic transformation is studied experimentally. A correlation has been established between the temperature dependences of the differential thermo-emf and the electrical resistance of the studied alloy. Unique thermal power and the effect of deformation on electrical properties are able to compete with mechanical power drives, tools and signaling devices. Their uniqueness lies in the ability to reversibly restore the original shape and dimensions under thermal power loading conditions and, at the same time, perform useful work, signaling changes in external conditions. The formation of the required structure and functional properties is facilitated by the formation of a system of dispersed particles.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"49 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":"74247440","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}
