Electrical properties of rutile-type Fe0.9 W0.1TiMO6 (M = Ta,Nb) ceramics were studied. The results are compared to those observed previously on rutile-type relaxor ferroelectric-like FeTiMO6 and Fe0.9 W0.05TiMO6 (M = Ta,Nb) ceramics. In part high di

A variety of electrical quantities of rutile-type Fex/2Ta(Nb)x/2Ti1-xO2 (x = 0.05, 0.1) ceramics were measured between room temperature and ≅ 760 K. One aim was to study the dielectric constant e(ω) (ω is angular frequency = 2πf) and dielectric

We determined a series of electrical quantities on rutile-type In 0.025Nb 0.025Ti 0.95O2 (INT005) and Al 0.025Nb 0.025Ti 0.95O2 (ANT005) ceramics in an attempt to analyse in particular the premises for formation of high dielectric constant 𝜖(ω) (

The microstructure of Li 2 TiO 3 ceramics, proposed as blanket material in deuterium–tritium fusion reactors, plays an important role for this application; grain size and grain shape determine to a considerable degree the properties in question. El

BACKGROUND The delayed increase of creatinine after radiocontrast application is a potential reason for overlooking radiocontrast nephrotoxicity. Cystatin C may be more useful to rapidly assess a decrease in glomerular filtration rate (GFR). We compa
