The Schottky barrier thermal/field assisted and Pool–Frenkel (PF) emission along with the punch-through in the central region of the film are proposed for the interpretation of experimental I–V dependence. It is shown that both the Schottky barrier thermal/-field assisted emission and Pool–Frenkel emission from the oxygen vacancies conditioned traps may take place simultaneously. The effect of electric field on the electron (hole) emission from the trapping centers, in the symmetric Pt/BST/Pt thin film structure has been considered. The analysis of the PF effect indicates that the trapping centers are activated at very high electric fields, exceeding 10 V/cm. In Part 2 of the paper, based on the results and assumptions pointed in Part 1, analytical expressions were derived for Schottky barrier thermal/-field assisted and Pool–Frenkel emission currents. The computer modeling theoretical dependencies of the I–V characteristics has been compared with the experimental measured results and obtained good agreements.","PeriodicalId":13355,"journal":{"name":"Image Journal of Advanced Materials and Technologies","volume":"130 1","pages":"008-017"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75315535","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 results of experimental testing confirming the effectiveness of ultra-jet technologies for producing liquid suspensions with nanomodifiers are presented. Two different types of powder were chosen as liquid modifiers: boehmite and carbon nanotubes. Moreover, special technological equipment was developed to conduct the experiment. The results of the analysis of the obtained liquid suspensions containing nanomodifiers allow us to recommend this dispersion technology for use on an industrial scale.","PeriodicalId":13355,"journal":{"name":"Image Journal of Advanced Materials and Technologies","volume":"39 1","pages":"068-075"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80355579","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 use of phenol-formaldehyde resin (PFS) as a binder component promoted good adhesion of graphene to the polymer matrix and made it possible to obtain samples of composites with a high graphene concentration of ~ 50 wt %. An increase in the shielding efficiency of composites was found both with an increase in the frequency of electromagnetic radiation and with an increase in the concentration of GNP in them. The maximum shielding value was 75 dB at a frequency of 12 GHz and graphene concentration of 50 % by mass.

Approximately 20–25 % of thermal energy can be saved by reducing heat loss through the windows, and 25–30 % of the electrical energy spent on lighting will be saved by using Smart Window technology instead of conventional windows, which are less energy-efficient in buildings.

The prospects of using various electrochromic materials as coatings for window glasses, mirrors, and large-area displays are considered.

High-speed milling differs from traditional milling by increasing the cutting speed by 10 times or more. Increasing the cutting speed and changing a number of other parameters of the high-speed milling process leads to a significant increase in cutting zone temperature and a change in the physico-mechanical properties of the sample surface layer, different from those that arise during traditional milling processing. In turn, the state of the surface layer affects the performance characteristics of parts – strength (static, cyclic, impact), wear resistance, resistance to corrosion, erosion and cavitation. A significant increase in the performance of high-speed milling is achieved by fulfilling the conditions for the correct selection of the cutting tool for the type, condition and configuration of the processed material surfaces, as well as determining the optimal parameters for high-speed milling, which maintains high performance characteristics of aircraft parts. The paper presents the results of determining the state of the surface layer of structural steel samples of grades 30HGSA and EP 817 used for the manufacture of compressor machine blades, sheathing housings, flanges and loaded parts of aircraft structures operating under alternating loads, respectively, after traditional and high-speed milling at different cutting speeds.","PeriodicalId":13355,"journal":{"name":"Image Journal of Advanced Materials and Technologies","volume":"10 1","pages":"027-035"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80365100","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}
