The amount of the phosphate precipitant was calculated to enable 100 % precipitation and the ratio of RE elements in the melt corresponded to that of RE fission products found in spent nuclear fuels. Molten salt was stirred with various rates during the precipitation. X-ray powder diffraction analysis was employed for identifying the compounds formed and particle size distribution curves were measured.","PeriodicalId":418936,"journal":{"name":"PHYSICS, TECHNOLOGIES AND INNOVATION (PTI-2019): Proceedings of the VI International Young Researchers’ Conference","volume":"20 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115217477","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}

Because the inhabitants of the skin phototype are in the special risk group for melanoma, it is necessary to carry out preventive diagnostics regularly. Long distances and a small population of the territory of the circumpolar region allow the creation of specialized dermatological centers only in large settlements. In the remaining points, general practitioners examine the patients. The quality of diagnosis of skin diseases depends largely on the experience and qualifications of the doctor. For high-quality diagnostics, general practitioners need a device that allows for several indicators to give an expert assessment of a neoplasm. We have created the concept of a device that helps the doctor to identify melanoma.","PeriodicalId":418936,"journal":{"name":"PHYSICS, TECHNOLOGIES AND INNOVATION (PTI-2019): Proceedings of the VI International Young Researchers’ Conference","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124888576","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}

We performed first principles computer simulations of the carbon dioxide (CO2) molecule adsorption on a ZnO surface in various configurations and location on the surface. It is shown that the tridentate configuration is the most energetically favorable, the binding energy of the molecule weakly depends on the surface coverage. The presence of intrinsic defects on the surface, such as an oxygen vacancy, leads to a small reduction of the binding energy. The observed data from the NEXAFS experiment and hypothetical formation of a new compound H2CO on the surface are discussed in the light of our calculations.Atomistic understanding of the interaction between defects and active surface of the sensor is necessary for the developing devices detecting bio-and gas mixtures.

It is shown that even in the case of a one-dimensional map, the presence of a random perturbation leads to the spiking.
