In this work, holey reduced graphene oxide (HRGO) was synthesized by the deposition of silver (Ag) nanoparticles onto the reduced graphene oxide (RGO) sheets followed by nitric acid treatment to remove Ag nanoparticles by microwave irradiation to form a porous structure. The HRGO were characterized by X-ray diffraction (XRD), field-emission scanning(More)
The purpose of this study was to determine the possible effects of the veneering porcelain thickness, and of repeated firing on the final shade of IPS e.max Press. Sixty disc-shaped IPS e.max Press specimens were fabricated and divided into 6groups according to shade (A2, C2) and porcelain thickness (0.5, 1.0 and 1.5 mm). Repeated firing (3, 5 and 7firings)(More)
