Many technical and scientific problems are solved successfully. One of the such problem is percolation (impregnation) — the theory what describes the appearance of infinite connected structures consisting of elements. This theory is used in field of capillary-porous material, such as leather or wood, in order to study their impregnation process and mass transfer. The purpose of this work is to study the possibility of determination speed and depth of chemical materials impregnation in capillary-porous materials using digital image processing techniques. The main objects of our research were the leather of cattle and linden wood samples. As leather tanning composition dry chrome tanning reagent was used. On it's basis aqueous solution at 90°C temperature was prepared. Aqueous solutions of dyes was used for wood samples processing. For the research the program has been developed by authors. This program determines color components on pictures taken during the leather tanning process in certain time interval. Digital image processing data determine quantitative characteristics of percolation process on porous materials. The mass transfer rate of leather tanning and wood impregnation based on the program data has been obtained. The method allows to improve the accuracy of determining the amount of reagent seeping into the porous materials, reduce laboriousness and material spending on research.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125628764","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}

Micellar synthesis method has certain advantages providing the obtaining of nanoscale monodisperse particles. In the reverse emulsion of bis (2-ethylhexyl) sodium sulfosuccinate (AOT)/n-hexane/water the cadmium sulfide nanoparticles were synthesized and their physicochemical properties were investigated. When the degree of hydration of inverse emulsions (W) is 5 or 10 the CdS nanoparticles band gap takes values 3.65 eV and 3.54 eV, the average particle size ranges from 2 to 5 nm respectively, while the larger particles are spherical, and the smaller cylindrical. By varying the hydration degree and controlling the interfacial tension of solutions of reverse micelles, implemented the ability to manage structural and electronic properties of the synthesized in them cadmium sulfide nanoparticles. Obtained solutions of QD are used as the foundation for development of compositions for inkjet technology applying to the surface.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121415143","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 purpose of the research is confirming technical possibility of designing an arcjet thruster for smallsat with power consumption 60…70 W and specific impulse 300…350 s. In the course of research tasks on determination of construction appearance of a demo sample of No. 2 of arcjet thruster, exploration of its temperature characteristics defining gauge of specific traction impulse of a study of erosion resistance of thruster cathode material at impact of an electric arc are resolved. A constructional scheme of arcjet thruster with visualization of an electric arc is developed, demo arcjet thruster samples are made and experimental arcjet thruster research is conducted in operation on nitrogen, argon. Working fluid temperature in arcjet thruster nozzle behind critical section is reached 1400 K at 68 W, which allows to predict specific impulse value of arcjet thruster in operation on ammonia in 300…350 s. On basis of experimental researches of erosion resistance of arcjet thruster cathode material (tungsten) at impact of an electric arc the necessity of the further research is shown for substantiation of a technical possibility of design arcjet thruster in composition of PS smallsat with required resource of operation. The experimental researches is the continuation of the works in the field of design of EHMT of various construction and represents practical interest during creation of PS for maneuvering smallsat.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124623106","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}
