Heat transfer with homogeneous structures of Si3N4 system and the effects oxygen defects in grains are reported by Jung Woo Lee co-workers article number 2100566. The moving to surface effectively captured getter. inhibition grain oxidization improves a spontaneous dissipation thermal energy.

Diamond single crystals showing Infra-red features of pressurized CO2-I phase were studied using Transmission Electron Microscopy (TEM) and tomography. Numerous O-containing precipitates with sizes up to 45 nm are observed. The absolute majority these decorate dislocation loops or located inside them; individual scattered also present. Morphology the varies from quasi-isometric octahedra highly...

We report on the characterization of gettered p-type GaP substrates for application in high-efficiency multijunction solar cells. A commercial zinc-doped GaP substrate was divided, with one piece soaked in a phosphorussaturated gallium-aluminum melt at 975 C. Low-temperature continuouswave photoluminescence indicated a significant decrease in deep-level impurity peaks due to oxygen and zinc-oxy...

The widespread application of intermediate-temperature solid oxide fuel cells is mainly being hurdled by the cathode's low efficiency on oxygen reduction reaction and poor resistance to carbon dioxide impurity. Here we report the fabrication of a hierarchical shell-covered porous cathode through infiltration followed by microwave plasma treatment. The hierarchical shell consists of a dense thin...

The effects on the lattice parameters due to incorporation of impurities in GaN are evaluated using firstprinciples pseudopotential-density-functional calculations. Both the size effect, due to the relaxation of host atoms around the impurity, and the deformation-potential effect, due to placing free carriers in the conduction or valence band, are investigated. The incorporation of silicon and ...

We present calculated electron excitation spectra for the LaMO3 series (M=Cr-Ni) obtained within ab-initio band structure calculations for the real geometric and magnetic structures. The calculated results show good agreement with the experimentally obtained spectra. This suggests that the transition metal-transition metal interactions via the oxygen atom play an important role in determining t...

Microstructure, precipitation hardening response, and mechanical and physical properties of Cu-Cr-Ag alloy and Cu-Cr-Ag-Ce alloy have been investigated using transmission electron microscopy, scanning electron microscope, optical microscope, electrical conductivity analysis, and tensile test. The influence of element Ce on the matrix refinement, impurity removal, and precipitation in the Cu-Cr-...
