The peculiarity of obtaining silver sulfide nanoparticles by biosynthesis using bacteria Bacillus subtilis 168 is that the only flagellin protein involved in the synthesis process and adsorbed on the surface of the particles. Investigated objects are salts-silver nitrate and sodium thiosulfate, which are involved in the synthesis process, and non-standard amino acid methyllysine as a part of flagellin. The study was based on of molecular structures and IR spectra calculation using density functional theory by the Gaussian 09 software package and on analysis of formed hydrogen bonds parameters. It was discovered that methyllysine forms a sufficiently stable molecular complexes with silver nitrate and sodium thiosulfate. This makes it possible to talk about the significant role of methyllysine in the formation of silver sulfide nanoparticles and clarifies the mechanism of its functioning as a part of flagellin.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133913539","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 need to create medium-capacity chamber-type defrosters with a capacity of up to 400 kg / hour is shown. The results of development of domestic chamber microwave defroster DMK-10.00 with a microwave power of up to 9 kW are presented. The working chamber of the defroster with a volume of more than 1300 liters and turntable operates in multi-mode mode. The installation operates at a frequency of 915 MHz from three magnetrons with microwave power of up to 3 kW. Antenna nodes for entering magnetron power are placed in the upper and lower parts of the unit to ensure uniformity of product warming. The performed tuning of the antenna power input nodes allowed us to obtain the values of the VSWR and transition attenuation coefficients between the antennas required for magnetrons. Research of microwave defroster has been carried out at high power level in the conditions of food industrial production. Operating modes of microwave defrosting of fish blocks and boxes with frozen butter have been developed. Options for upgrading the plant design to increase defrosting performance are proposed.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125922550","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}
