Objective: The aim was to evaluate the effect of activated bleaching agents on nanoceramic composite resins based microhardness and surface roughness measurements.
 Methods: Opalescence Boost (Ultradent Products, USA) Whiteness HP Blue Calcium (FGM Dental Brazil) a resin Ceram.X® SphereTEC™ One (DENTSPLY, Germany) were used in study. Fifty samples disc form (8x2mm) prepared. polished with ...

It is shown that the GaN nanoceramics fabricated by low-temperature high-pressure technique exhibit ferromagnetic behavior. The measurements reveal magnetization of increased with sintering pressure to 8 GPa applied in fabrication process nanoceramics. suggested magnetostriction mechanism responsible for observed increase ferromagnetism nanoceramic measured at 2 K has decreased nonlinearly orde...

A composite materials were prepared using a polymeric blend of epoxy resin and unsaturated polyester as matrix material, nanoceramic powder Lead Zirconium Titanate reinforcement material in different adding ratios( 2wt % & 6wt ). Impact strength, surface hardness, thermal conductivity solutions absorption tests carried out for the samples. The pre-immersion results showed that ceramic to improv...
