متن کاملModelling of point defects in monoclinic zirconia
We present the results of plane wave density functional theory calculations of oxygen vacancies and interstitial oxygen atoms in monoclinic zirconia. After calculating the incorporation energies and structures of interstitial oxygen atoms and formation energies of neutral oxygen vacancies, we consider the electron affinities and ionisation potentials of these defects. These properties are espec...
متن کاملSynthesis of pure monoclinic zirconia nanoparticles using ultrasound cavitation technique
In the current study, synthesis and characterization of a new nano-structured zirconium(IV)-minoxidil complex (1), where minoxidil, (C9H15N5O; 6-(1-Piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. The compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (MEG) as solvents and characterized by scan...
متن کاملFracture toughness of graphene.
Perfect graphene is believed to be the strongest material. However, the useful strength of large-area graphene with engineering relevance is usually determined by its fracture toughness, rather than the intrinsic strength that governs a uniform breaking of atomic bonds in perfect graphene. To date, the fracture toughness of graphene has not been measured. Here we report an in situ tensile testi...

. AbstrAct Objective. In clinical practice, core material can be exposed after adjustments, which may result in loss of ceramic glaze. The objective of this study is to evaluate the effect of surface roughness on the flexural strength and fracture toughness of In-Ceram zirconia core material. Materials and methods. Forty In-Ceram zirconia specimens were prepared and divided into two main groups...
