In last decade, heterocyclic compounds containing thiazole moiety and their derivatives were found exhibiting nanoscale properties. In addition, they exhibit a wide spectrum of biological activities such as antioxidant, antitubercular, antiinflammatory, anti-HIV, antitumor, anticonvulsive, antifungal and antibacterial.

The conditions of percolation transition in 5 nm thick silver films deposited on germanium underlayers in the range of 1 nm are studied. The influence of germanium underlayers with a mass thickness up to 1 nm with a step of 0.2 nm in the visible and near-infrared wavelength range (300–2500 nm) on the above-mentioned properties of silver films is investigated. Optical percolation in silver films is associated with the peculiarities of growth mechanisms and modes of formation of metal condensate on an amorphous glass substrate. As shown, the germanium underlayers previously applied to the glass substrate reduce the threshold thickness of the optical percolation transition in the silver film and increase their absorbency compared to similar films formed on a clean glass surface. The increase in the absorption capacity of films deposited on the surface of the germanium underlayer is due to a decrease in the average linear size of crystallites compared to similar samples formed on a clean glass surface, and thus, an increase in the number of scattering metal centres per unit surface area.","PeriodicalId":18830,"journal":{"name":"Nanosistemi, Nanomateriali, Nanotehnologii","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43926857","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}

Metakaolin and zirconia are potential alternatives as dental restoration materials. This study aims to determine the characteristics of synthesized metakaolin–zirconia geopolymer nanocomposite with the addition of tapioca as a template. The study is a pure experimental laboratory investigation. The sample is fabricated by means of both the synthesis of metakaolin, zirconia, alkali activator, chitosan and the addition of tapioca of 0.4% v/v, 0.8% v/v, and 1.6% v/v. Alkali solution consisting of NaOH and Na 2 SiO 3 is used to activate the geopolymerization of me-takaolin. Nanocomposite characteristics with variations of the addition of tapioca template are then evaluated for its hardness and microstructure. Synthesis of metakaolin–zirconia geopolymer nanocomposite with the addition of tapioca template is successful, and it has a mean hardness value, which has met the hardness value used for dental composite restoration and has the best attachment to artificial teeth.
