The properties of barium titanate (BaTiO3 , BT), such as high dielectric constant and resistivity, allow it to find numerous applications in the field of microelectronics. In this work silicon metal-insulator-semiconductor field effect transistor (MISFET) structures with BaTiO3 thin films (containing La2O3 admixture) acting as gate insulator were investigated. The films were produced by means o...

Various types of sodium and potassium titanate nanostructures (nanotubes, nanofibers, nanoribbons, nanwires) were synthesized and characterized by X-ray diffraction, SEM and TEM, as well BET and BJH methods. Adsorption of radiotracer 137Cs+ ions from aqueous solutions on synthesized titanate nanostructures was investigated in batch technique as a function of contact time, concentration of sodiu...

An evaluation of the performance a recently developed formulation (lead-free) Sodium-Bismuth titanate – Barium Titanate (NBT-BT) piezoceramic is presented through construction and testing several immersion transducers based around new material “Pz12” from CTS Ferroperm (Kvistgaard, Denmark). Results are intended to yield insight into applicability this lead-free for use within industrial, NDT, ...

In this study, TiO2 based nanotubes and nanosheets were synthesized to be used as an adsorbent and support in various processes. As a starting material, sol-gel synthesized anatase and commercial anatase were used. TiO2 was converted to high surface area hydrogen titanate (H2Ti3O7) and sodium titanate (Na2Ti3O7) nanotubes and nanosheets under alkaline conditions with hydrothermal treatment. In ...
