A paradigm shift in dental caries treatment paediatric dentistry is viewed towards a wide using of composite resins. This prospective clinical trial are evaluated and compared during 18 months performance microhybrid with nanoceramic resin placed сlass I II cavities permanent teeth children. 
 Thirty one children aged between 7 15 years were investigated this study. About 40 restorations p...

Transparent Y3Al5O12-based polycrystalline ceramics with excessive Al2O3 composition (Al2O3-26 mol%Y2O3, AY26) have been demonstrated as potential host materials for phosphor applications. However, the crystallization mechanism of AY26 glass has not thoroughly investigated so far. In this work, non-isothermal kinetics was experimentally analyzed. The depicts high activation energy and volume nu...

The demand for decreasing CO2-emission and harmful material content of the exhaust gas passenger cars requires improvement entire powertrain including applied lubricants. One possible future engines lubricant can be nano-sized ceramic particles, which provide positive tribological properties also in presence nonmetallic surface materials. This paper presents experimental investigation ZrO2 nano...

Abstract Pt-WO 3 composite nanoceramic produced by pressed and sintered with 5 wt% Pt WO nanoparticles has a response multiple of about 80 for 800 ppm H 2 -20% O -N 10 100 at room temperature 40 relative humidity(RH), showing an impressive sensing capacity low concentration hydrogen. However, will show the aging phenomenon mainly rapid decline recovery rate in open air, which limits its applica...

The heterovalent solid solution Sr1−xYxF2+x with fluorite structure (sp. gr. Fm-3m) can be synthesized in single-crystal and nanoceramic forms. Comparison of their electrical properties shows that nanoceramics have a higher ionic conductivity than single crystals the same composition. In state solution, migration mechanism dominates interstitial ions F' bulk sample, ther is vacancy V• along gra...
