Introduction: At high magnetic fields radiation losses, wavelength effects, self-resonance and decreased Q of typical components all contribute to increased losses in conventional RF coil designs. High permittivity ceramic dielectric resonators create strong uniform magnetic fields in a compact structure at high frequencies, are extensively used in radiocommunications applications, and can pote...

A rough surface texture was found on laser sintered titanium substrate, which was responsible for instability of the calcium phosphate layer from the point of view of obtaining good adhesivity to the substrate at given preparation conditions. After the mechanical treatment and following soaking of Ti substrate in 3 M NaOH solution, the surface texture was much smoother than in the original samp...

Organic modification of nano-SiO2 particles was performed with supercritical CO2 as solvent and a titanate coupling reagent NDZ-201 as the modification reagent. The surface of the nano-SiO2 particles was changed after modification by the titanate coupling reagent from hydrophilic to hydrophobic. IR and thermo-gravimetric analyses indicate that the interaction between the titanate coupling reage...

In this work, pellet samples of barium calcium zirconate titanate (Ba1-xCaxZr0.1Ti0.9O3, x=0.065) were prepared using solid state reaction route with double sintering. The structural and piezoelectric properties measured. Further, SEM EDAX analysis observed. With different sintering temperature, the density grain size changed further, their effect in has been For samples, converse constant (d33...
