We theoretically demonstrate high Quality factor (Q~3×10 6 ) micropillar cavities with record low mode volumes [V~0.1(λ/n) 3 ] based on the TiO2/SiO2 material system. The proposed cavities have Q/V three orders of magnitude larger than previously reported ones. We show that our cavity embedded with diamond nanocrystal provides a feasible platform for cavity quantum electrodynamics experiments i...

During the refining process of Incoloy825 nickel-based alloy, reaction between slag and Al Ti in alloy can result oxidation loss. Therefore, effect TiO2 Al2O3 contents (CaO–SiO2–Al2O3–MgO–CaF2–TiO2) on final was investigated by slag-metal experiment a 1-kg MoSi2 resistance furnace. The thermodynamic model established based ion molecular coexistence theory kinetic two-film theory. experimental r...

Objective(s): Quince seed mucilage (QSM) serves as a new source of hydrocolloid which extracted from outer pericarp of Cydonia oblonga seeds upon wetting. It has been traditionally used for the treatment of diseases such as pharyngeal disorder, common cold, colic ulcer, and diarrhea. The aim of the present study was to evaluate the physico-mechanical and antimicrobial properties of quince seed ...

The article presents results of comparative A-TIG welding tests involving selected unalloyed and fine-grained steels, as well high-strength steel WELDOX 1300 austenitic stainless AISI 304L. involved the use single ingredient activated fluxes (Cr2O3, TiO2, SiO2, Fe2O3, NaF, AlF3). In cases carbon low-alloy revealed that greatest increase in penetration depth was observed steels which had been de...

Rapid atomic layer deposition (RALD) has been applied to prepare various nanolaminates with repeated multilayer structures. The possible reaction pathways for RALD of the Al2O3/SiO2 nanolaminate using trimethylaluminum (TMA) and tris(tert-butoxy)silanol (TBS) are investigated by using density functional theory (DFT) calculations. The introduction of a Lewis-acid catalyst, TMA, can result in the...

TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...

This paper presents a study of the mechanical properties and an evaluation of damage mechanisms of nanocolumnar TiO2-SiO2 multilayer coatings prepared by physical vapour oblique angle deposition at different configurations (slanted, zigzag or chiral) and two zenithal evaporation angles (70o or 85o). The characterization at microand nano-metric length scales of the mechanical properties of the m...
