This numerical procedure is recommended and applied on triangulated file coming from 3D scanners or Topology optimization designs based on voxel representation before the optimized structure is manufactured by Additive Manufacturing technologies. In literature, there are several available algorithms, but many of them suffer from mesh shrinkage and do not give to the designer easy procedures to select regions which do not need the application of the smoothing procedure as holes or flat surfaces. For this reason, an improved vertex-based algorithm is presented in this work along with a case study to prove its performances compared with existent algorithms. The algorithm confirms to be efficient and useful. However, user’s intervention is required to guide the procedure to get proper results.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"299 1","pages":"02SAMA19-1-02SAMA19-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73583126","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}

MoS2 was nanoscale core coated with functional polymer via polymerization initiated from the particles surface using different macroinitiators. Both thermodynamic and kinetic peculiarities of intercalation processes were evaluated by the method of computer modeling of impedance spectroscopy experimental data. Dependences of 1) change in Gibbs’ free energy of the intercalation reaction, 2) Helmholtz’ capacity and 3) charge transfer resistance on the extent of “guest” lithium loading were analyzed. The electrochemical measurements revealed the dependences of above parameters of the intercalation process in core-shell MoS2 nanocomposites on macroinitiator nature. The distinctive feature of macroinitiator fluorine alkyl hydroxy acid was ability of synthesized material to ensure 1) the specific capacity in cathode processes up to $sim$1936mAh/g and 2) diffusion coefficient of lithium cations up to more than twice.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"72 1","pages":"02NEE14-1-02NEE14-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76574529","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}

Decomposition temperatures for $mathrm{S}mathrm{c}{}_{1-x}mathrm{L}mathrm{n}_{x}mathrm{V}mathrm{O}_{4}$ solid solutions with x=0.01,0.02,0.05,0.10, and 0.20 were calculated with crystal chemical method of regular solution approximation. A diagram which allows to determine decomposition temperature with given equilibrium substitution limit (x), or substitution limit with given temperature and assess areas of stability, instability, and metastability for $mathrm{S}mathrm{c}{}_{1-x}mathrm{L}mathrm{n}_{x}mathrm{V}mathrm{O}_{4}$ solid solutions is presented. Results of calculations were compared with literature data on thermodynamic stability of solid solutions and on substitution limits. The results of the study can be used during development of new luminescent materials based on $mathrm{S}mathrm{c}mathrm{V}mathrm{O}_{4}$, which are modified with rare-earth elements, at defining rare-earth elements in matrix and activator, at defining optimal proportions of REE in $mathrm{S}mathrm{c}{}_{1-x}mathrm{L}mathrm{n}_{x}mathrm{V}mathrm{O}_{4}$ matrixes. Using the XRD method, including the Rietveld structure refinement was found that the substitutional limit of Gd for Sc (x) in a series of solid solutions $mathrm{S}mathrm{c}1-xmathrm{G}mathrm{d}_{X}mathrm{V}mathrm{O}_{4}$ is about 0.13, which is in satisfactory agreement with the result of the calculation (x=0.18). The effect of substitutions on the luminescent properties of $mathrm{S}_{mathrm{C}1-x}mathrm{G}mathrm{d}_{x}mathrm{V}mathrm{O}_{4}$ is shown: with the introduction of 9% Gd in $mathrm{S}mathrm{c}mathrm{V}mathrm{O}_{4}$, the intensity of intrinsic luminescent radiation increases to a greater degree.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"13 1","pages":"01NSSA09-1-01NSSA09-6"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79365876","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 chemical composition of the sorption material includes inorganic (HA, ZnO) and organic (CS, Alg, glutaraldehyde, glycerin) components. The applied technology of ionotropic crosslinking and sublimation and the chemical composition of the material gives the material shape stability and allows control of the degree of swelling and porosity. The additional introduction of the antibiotic Ceftriaxone and agents with antimicrobial action (chitosan, zinc oxide) inhibit bacterial cells in conditions of advanced peritonitis. The composite material is hydrophilic. Its degree of swelling, which characterizes sorption capacity, is 240-380%, depending on the chemical composition. In vivo studies show that due to the sorption properties of HA and organic components, the created drainage system reduces the exudation phase, exhibits detoxification and antibacterial properties. Drainage can be used in surgery for the treatment of purulent - necrotic foci of various origins.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"13 1","pages":"02BA02-1-02BA02-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81965264","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}

Nevertheless, the printing process leads to material and shape defects, residual stress and induced distortions on final components that mainly are caused by the high thermal gradients associated to the intense and nonuniform power energy sources used to selectively melt metal powders. In this paper, techniques to reduce or prevent these effects are summarized. The more broadly Design for Additive Manufacturing approach based on the use on CAD platforms for product-process design is the backbone upon this research is based on. Specifically, the work presents a design method to predict drawbacks and improve the industrialization subphase. Laser-based Powder Bed Fusion technique is considered and the implementation and validation of the Selective Laser Melting process simulation is performed in order to support the method. Two case studies are presented. The former demonstrates the simulation implementation feasibility through a CAD platform. The latter validates the simulation results compared to experimental data for further method application.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"122 1","pages":"02SAMA13-1-02SAMA13-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88021396","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}
