The electron paramagnetic spectra of trigonal Mn2+ centers in [Co(H2O)6]SiF6, [Co(H2O)6] SnF6, and [Co(H2O)6]PtCl6 crystals were studied on the basis of the complete energy matrices for a d5 configuration ion in a trigonal ligand field. When Mn2+ is doped
The effects of initial oxygen concentration on the reverse leakage current of PIN rectifier diodes were studied. We fabricated the PIN rectifier diodes with different initial oxygen concentrations, and analyzed the electrical properties, anisotropic prefe
Because of its merits, acrylic resin was chosen to improve the mechanical, conductive and hydrophobic properties. Carbon fiber powders (CF), carbon nanotubes (MWCNT), and nano-TiO2 were incorporated into the acrylic resin to prepare the corona-proof condu
ZrO2-5CrMnMo composite samples were prepared by hot press sintering. When NiCoCrAlY powders were used as the bonding layer and the different mixtures of NiCoCrAlY alloy and 3YSZ (3mol% yttria stabilized zirconia) ceramic powders were used as the transitio
Three-dimensional finite element physical models considering the layered distribution of materials at the interface were developed to study the effect of the coating system on distributions of thermal residual stresses in SiCf/Ti2AlNb composites. Two coat
The Ge metal-oxide-semiconductor (MOS) capacitors were fabricated with HfO2 as gate dielectric. AlON, NdON, and NdAlON were deposited between the gate dielectric and the Ge substrate as the interfacial passivation layer (IPL). The electrical properties (s
We investigated the impure phase problem and summarized its two formation mechanisms of YAG powders synthesized via the co-precipitation method. The ions loss problem caused by high concentration reaction solution in the titration process was emphatically
The microstructure and thermal characteristics of Mg-36%Ga, Mg-43%Ga, and Mg45%Ga(wt%) alloys were investigated. The experimental results show that the microstructure of Mg-36%Ga alloy is mainly composed of primary α-Mg phase and α-Mg+Mg5Ga2 eutectic phas
Epoxy resin (EPR) was used to crosslink with Camellia oleifera Abel. protein to prepare wood adhesive, and the bonding performance and curing characteristics of which were mainly investigated, and the synthesis mechanism was also discussed by using model
Four polyaniline-tea saponin (PTS) nanocomposites were prepared by an in-situ polymerization with tea saponin (TS) as a biosurfactant, and they were used to remove organic dyes from aqueous solution. The PTS nanocomposites were characterized by using fiel
