Journal ArticleDOI
Electrical Conduction in Insulator Particle—Solid‐State Ionic and Conducting Particle‐Insulator Matrix Composites A Unified Theory
TL;DR: A unified model for electrical conduction in both the insulator particle solid state ionic and conducting particle insulator matrix composites was introduced for the first time in this article, where the basic formulation of effective medium approximation was reconsidered by replacing the site conductivities with the contact conductivities as well as the probability of site occupation with the probability for contact development.
Journal ArticleDOI
Optical band gap and ultralow dielectric constant materials prepared by a simple dip coating process
TL;DR: In this paper, a simple procedure for producing ordered porous silica films, with pore sizes in the range of 40-1000 nm, was described, where precursors were prepared by mixing polystyrene latex (PSL) colloidal spheres and silica nanoparticles.
Journal ArticleDOI
Direct synthesis of barium magnesium aluminate blue phosphor particles via a flame route
TL;DR: In this paper, a flame spray pyrolysis method to directly prepare submicron BaMgAl10O17:Eu2+ (BAM: Eu) phosphor particles was designed.
Journal ArticleDOI

TL;DR: In this paper, the effect of Zr doping on the performance of dye-sensitized solar cells (DSSCs) based on Zr/N-doped TiO2 photoelectrodes was investigated.
Journal ArticleDOI
Gas-Phase Nucleation in an Atmospheric Pressure Chemical Vapor Deposition Process for SiO 2 Films Using Tetraethylorthosilicate (TEOS)
TL;DR: In this article, the formation of a SiO2 film on a substrate and the generation of particles in the gas phase were examined simultaneously in an atmospheric-pressure chemical vapor deposition (APCVD) process using tetraethylorthosilicate (TEOS).
