Current-voltage characteristics of the MoRe/Si(W)/MoRe samples have been measured in a wide voltage range from −900 to 900 mV at temperatures from 4.2 K to 77 K. At low temperatures and for a comparatively small W content in the hybrid barrier, the heterostructures demonstrate current-voltage curves of an unusual shape. Single or several current peaks caused by electron tunneling through the allowed states in the barrier have been observed in the transport characteristics. With increasing temperature, superconducting fluctuations in the MoRe electrodes become unimportant, and the current-voltage curve of a heterostructure follows the Ohm's law. At last, we present theoretical description of the charge transport in such inhomogeneous systems with account of many-electron processes.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115499892","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 has been considered the features of the conversion coatings formation on silumin by plasma electrolytic oxidizing in alkaline electrolytes based on potassium pyrophosphate. The effect of the electrolyte components and processing conditions on the composition and the morphology of the surface layers has been studied. Plasma electrolytic oxidizing of internal combustion engines pistons allows the formation of alumina matrix containing manganese and cobalt oxides which evinces high catalytic properties. Manganese-containing oxide system demonstrates the highest fuel economy at 3–4 %. When using a piston with a cobalt oxides coating, toxic gas emissions are reduced: NOxwithin 10 % and CO - of 15–18 %. The proposed systems can find application in intra cylinder catalysis technologies in order to reduce the toxicity of gas emissions of engines and increase their fuel efficiency.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"1020 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123120088","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 demonstrated, that obtained TiO2-SnO2 nanocomposites show better photocatalytic performance towards anionic dyes (congo red) than towards cationic dyes (methylene blue) and the photocatalytic activity increases with the increase of SnO2 content.

Among many kinds of catalytic materials and composites with its participation, Ni, Co-spinel attracted great interest, especially as electrode material for electrochemical energy storage/conversion systems, due to its higher theoretical specific capacity than conventional graphite. The main advantages of nickel cobalt spinel and composite materials with its participation are high electrical resistivity and electron conductivity, high rate capability, thermodynamic stability and durability. Peculiarities of the crystal structure of spinels cause such properties. Ni, Co-spinels refer to single-phase triple oxides of the inverse spinel type with two different metal cations. Inverse spinels have considerable electrical conductivity due to the possibility of electron exchange between divalent and trivalent ions in the octahedral position. Due to the presence of such structural features, inverse spinels can be successfully used as electrocatalysts in energy storage/conversion systems. Synthesis approaches of Ni, Co-spinel and composites with its participation include hydrothermal method, microwave synthesis, coprecipitation method, dry synthesis technique and sol-gel method. Establishing a connection between methods and conditions of synthesis, as well as a comprehensive understanding of the methods used to modification the obtained samples, is an important scientific and practical task and an urgent topic for further research in this field.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132032746","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}
