To prepare these catalysts, the PAN-ACFs obtained by onestep carbonation-activation were modified with a surface coverage of high acidity. The surface of PAN-ACFs was sulfurated with sulfur vapors at high temperatures followed by oxidation, to yield the corresponding sulfonates. The chemical analysis showed that the carbon surface layer contains from 1.28 to 6.10 mmol$mathrm{g}^{-1}$ of sulfur, including the contribution of sulfonic $(mathrm{S}mathrm{O}{}_{3}mathrm{H})$ groups. In addition to sulfonic groups, the obtained catalysts contain carboxyl, lactone, and phenolic groups, which are formed as a result of oxidation treatment. In order to understand the changes in surface chemistry and the results of sulfuration and oxidation, the sulfonated PAN-ACFs were characterized by a variety of techniques including TPD MS, TGA, SEM, and FTIR ATR. During a typical temperature mode screening at catalyst testing, it was found that the sulfonated PAN-ACFs prepared by treatment with sulfur vapor at low temperature, at $400circ mathrm{c}$ and $500circ mathrm{c}$, are very efficient at dehydrating 2-propanol. A weighed mass of 100 mg of each of these catalysts was operated at 165-175°C in 12 hours, and the catalysts were characterized by high conversion of 2-propanol and high selectivity to propylene, with a propylene yield of about 100%. Furthermore, the solid acid catalysts have high stability and strong acidity and can be reused with no significant loss in the activity after the third cycle in the subsequent 20 cycles. The preparation of solid acid catalysts from PAN-ACFs affords a novel strategy for producing propylene through alternative green and sustainable technologies.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"101 1","pages":"01TFC07-1-01TFC07-6"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83334919","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}

In Powder Bed Fusion (PBF) processes like Selective Laser Melting (SLM) and Electron Beam Melting (EBM), one of such factors is a build orientation of a part. To investigate an effect of the part orientation a set of samples have been manufactured via the EBM. The microstructure and microhardness characterization showed that vertical orientation of the components could be preferable if homogeneity of mechanical properties is critical for the particular application, but it may increase the manufacturing time.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"16 1","pages":"02SAMA08-1-02SAMA08-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82015303","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 finite element method was used. A special eight-node finite element has been developed and numerically implemented. Solving the problems of nonlinear deformation of nanomodified polymer compositions is carried out on the basis of the Newton-Kantorovich algorithm, supplemented by a block that implements the method of variable stiffness, taking into account the modified Morse potential. Comparison of the results of numerical solutions of control problems with other numerical solutions known from the literature indicates their good agreement. As an example, the results of modeling the evolution of progressive fracture when pulling out a nanotube from a reactoplastic polymer matrix are presented. The developed methods make it possible to reliably determine the physical and mechanical characteristics of nanomodified polymers and the strength of structures based on them.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"16 1","pages":"02TM06-1-02TM06-7"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77211643","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}
