چکیده
The possibility of using the "Brazilian test" method to determination tensile strength σt composite zirconia ceramics small-size samples were demonstrated and reliability obtained values confirmed. It was found that dependence alumina toughened (stabilized by calcium oxide) with silica addition (CaO-ATZ+SiO2 ceramics) on SiO2 concentration in them has a maximum (σt = 450 MPa, at 5 mol.%). observed is explained an increase transformability tetragonal t-ZrO2 phase and, accordingly, enhanced role transformation toughening when adding into ATZ ceramics.

Synthesis and Characterization of Monodisperse Metallodielectric SiO<sub>2</sub>@Pt@SiO<sub>2</sub> Core–Shell–Shell Particles
Metallodielectric nanostructured core−shell− shell particles are particularly desirable for enabling novel types of optical components, including narrow-band absorbers, narrow-band photodetectors, and thermal emitters, as well as new types of sensors and catalysts. Here, we present a facile approach for the preparation of submicron SiO2@Pt@SiO2 core−shell−shell particles. As shown by transmissi...
متن کاملMelting of Forsterite, Mg<sub>2</sub>SiO<sub>4</sub>, From 9.7 to 16.5 GPa
A multianvil apparatus ha been used to determine th pressure-temperature mel ing curve of forsterite from 9.7 to 16.5 GPa. At 10.1 GPa a singular point occurs that marks the change from congruent melting at lower pressures to incongruent melting (forsterite periclase + liquid) at higher pressures. The melting curve also passes through two invariant points. At one (15.6 GPa, 2310øC), the phases ...
متن کاملLimitations of Poole–Frenkel Conduction in Bilayer HfO<sub>2</sub>/SiO<sub>2</sub> MOS Devices
The gate leakage current of metal–oxide– semiconductors (MOSs) composed of hafnium oxide (HfO2) exhibits temperature dependence, which is usually attributed to the standard Poole–Frenkel (P–F) transport model. However, the reported magnitudes of the trap barrier height vary significantly. This paper explores the fundamental challenges associated with applying the P–F model to describe transport...
متن کاملAtmospheric Oxygen Binding and Hole Doping in Deformed Graphene on a SiO<sub>2</sub> Substrate
Using micro-Raman spectroscopy and scanning tunneling microscopy, we study the relationship between structural distortion and electrical hole doping of graphene on a silicon dioxide substrate. The observed upshift of the Raman G band represents charge doping and not compressive strain. Two independent factors control the doping: (1) the degree of graphene coupling to the substrate and (2) expos...
متن کاملNanoherding: Plasma-Chemical Synthesis and Electric-Charge-Driven Self Organization of SiO<sub>2</sub> Nanodots
We report on the chemical synthesis of the arrays of silicon oxide nanodots and their self-organization on the surface via physical processes triggered by surface charges. The method based on chemically active oxygen plasma leads to the rearrangement of nanostructures and eventually to the formation of groups of nanodots. This behavior is explained in terms of the effect of electric field on th...
