Barium stannate titanate (BaTi0.89Sn0.11O3, BTS11) is one of the reported lead-free materials that exhibit high dielectric and piezoelectric properties near ambient temperature. In this work, BTS11 powders were elaborated via a soft chemistry method at very low temperatures using two synthesized approaches combining sol-gel hydrothermal processes. first approach, effect barium precursor on puri...

In this work, we have studied the methods of electrochemical processing materials in order to give them new functional properties. Experimental data on production corrosion-resistant coatings based Zn-Ni and Zn-Co alloys from ammonium oxalate electrolytes study their protective properties are presented. The questions carbon nanomaterials by anodic exfoliation graphite sulfuric acid considered. ...

Layered Eu-doped SnO₂ ordered nanoarrays constructed by nanorods with 10 nm diameters and several hundred nanometers length were synthesized by a substrate-free hydrothermal route using alcohol and water mixed solvent of sodium stannate and sodium hydroxide at 200 °C. The Eu dopant acted as a crystal growth inhibitor to prevent the SnO₂ nanorods growth up, resulting in tenuous SnO₂ nanorods ord...

introduction : this investigation evaluates the effects of mineral trioxide aggregate (mta), calcium hydroxide (ch) and calcium enriched mixture (cem) as pulp capping materials on dental pulp tissues. materials and methods: the experimental procedures were performed on eighteen intact dog canine teeth. the pulps were exposed. cavities were randomly filled with cem, mta, or ch followed by glass ...

As an important new flame retardant, zinc stannate (ZS) shows wide application prospects due to its many advantages. However, the retardant mechanism of composites made with polymer combined ZS is still unclear. In particular, there a lack molecular level description micro-scale mechanism. The combustion through simulation technology has become research paradigm in field fire, which can provide...
