The obtained results demonstrate that 160 nm diameter ZnO nanospheres scatter light predominately into the active layer, enhancing the light absorption of the organic material. The results were obtained by covering 25% of the organic solar cell active layer surface with ZnO nanospheres. At 550nm the absorption enhancement value reachs 12%. At 650 nm the absorption enhancement reachs up to 35x. The findings indicate that ZnO nanospheres can improve the performance of organic solar cells.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"26 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85931618","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}

It is established that after the introduction of surfactants, the interlayer distance in montmorillonite (MMT) increased. This indicates the intercalation process of surfactant molecules into the interlayer space of the MMT. After introduction to polymer matrix the increase in the interlayer distance is observed. This indicates the intercalation of two monolayers of OEG and the formation of quasibilayer structures. It is shown that the structure of OEG-based systems significantly depends on the content of the nanofiller. Partial processes of intercalation are observed in OEG-organoclay nanocomposites.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"64 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90564714","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}

Also after annealing AlNiCoFeCrTi HEA powder contains intermetallic σ-phase and TiC particles which retain in powder after its grinding. So, before deposition the feedstock powder consists of disordered bcc solid solution, an intermetallic σ-phase, and TiC carbide. Mean thickness of deposited coatings is about 450 μm. Due to low temperature of CS process, AlFeNiCoCrTi coating has same phase composition and nanostructural state as a feedstock powder. The Vickers hardness of AlFeNiCoCrTi HEA coating is 10.3±0.3 GPa. Coating has very low porosity (<1%) and good adhesion to the steel substrate. High strength characteristics of the coating are provided by the high characteristics of feedstock powder and its strengthening mechanisms, as well as impact hardening during spraying at a supersonic speed at low temperature.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89567986","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}
