A composit catalyst of Graphite Oxide load Co3O4 (GO-Co3O4) was prepared with a simple method, and its performance in the degradation of azo dyes Acid Orange II (AO7) using potassium monopersulfate compound (Oxone) as an oxidant was investigated. The results indicate that GO-Co3O4 can be successfully applied as hetero…
Spherical microstructures with core–shell features were assembled and stabilized by welding them in supercritical carbon dioxide (SC CO2). Hollow poly(styrene-co-divinylbenzene) (PS-co-DVB) capsules and polystyrene (PS) particles were used as building blocks and supporting cores, respectively. By adjusting the diamete…
Washed kaolin produced in Maoming, Guangzhou was used as the raw material and NaOH and NaAlO2were used as the modifiers to prepare a high-performance deaminating material by providing kaolin with sodium-type exchange groups through modification and calcination. Then the ammonia ion exchange capacity of this material w…
Cyclic voltammograms of reactive black5 (RB5) at different pHs in the range 1.0 - 13.0 on multiwall carbon nanotube modified glassy carbon electrode revealed the presence of one well-defined irreversible anodic peak around 975 mV in acidic and neutral pHs. Adsorption controlled oxidation observed at acidic pH 1.0 resu…
Y2Si2O7–MoSi2/SiC multi-composition coatings were deposited on the surface of SiC pre-coated carbon/carbon (C/C) composites using a hydrothermal electrophoretic process. The prepared coatings were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Influences of Y2Si2O7 whisker on the morp…
Abstract This work describes the development of texture during hot rolling of three binary alloys, namely Ti-8Nb, Ti-12Nb and Ti-16Nb. The alloys have been unidirectionally hot rolled at 800°C and air cooled. The alloy Ti-8Nb consists of the α (cph) and small volume fraction of β (bcc) phases while the alloys Ti-12Nb…
Nanostructured silicon nitride and aluminium nitride powder mixtures have been successfully produced by high-energy mechanical activation in the planetary mill. The effect of planetary milling parameters (time, ball-to-powder ratio, surfactants addition) and means of deagglomeration by the ultrasound disintegration (t…
We report an unusual and rare cause of preauricular swelling and review the most recent literature concerning synovial osteochondromatosis of the temporomandibular joint. We report the clinical and radiologic findings of a case of synovial osteochondromatosis of the temporomandibular joint that presented as preauricul…
The icosahedral Al is a "magic" cluster with remarkable stability due to its high symmetry and closed valence shells. Its reactivity has provided a molecular model for understanding oxidation and dissolution processes in bulk metals. By first principles calculations, we demonstrated the importance of dynamic factors i…
Nowadays, precise prediction of heat generation in semiconductor devices is important. An electro-thermal analysis is an attractive method to predict heat generation in devices. In this analysis, momentum and energy relaxation times are taken as the important parameters. Calculated heat generation density is dependent…
CdSe/PVA nanocomposites are fabricated by chemical bath method. The third order nonlinear optical measurement of CdSe/PVA nanocomposite film is carried out using a single beam z‐scan technique with a low power CW He–Ne laser at 633 nm wavelength. The transmittance as a function of sample position is studied for closed…
We reported an alternative strategy to reduce disulphide bonds in peptides with Ag-nanoparticle loaded nano-TiO(2) (Ag/TiO(2)) under UV irradiation. The feasibility of this strategy was adequately demonstrated using the model peptides oxidized glutathione, vasopressin and insulin, which contain various disulphide bond…
We’ve built this digital research platform to provide academics everywhere with fast, stable and secure digital access to our library of over 110,000 scholarly books and 800,000 journal articles. We’ve tested the platform in close cooperation with leading academic institutions. If you have any questions or you notice…
High surface area electrodes made of TiO 2 +WO 3 +C powder coatings have been prepared and tested as photoanodes in mini-photoelectrochemical cells based on Nafion® electrolyte-impregnated microporous membranes. Photovoltammetry and constant potential photoamperometry, carried out at the (TiO 2 +WO 3 +C)/Nafion® photo…
The vapour transport equilibration (VTE) is used to change the Li/Ta ratio in lithium tantalate single crystals of different crystallographic orientations (Z-cut and Y/128°-cut). Treatment by VTE is shown to provide thin layers in lithium tantalate plates composition of which is close to stoichiometric while the value…
We report on the synthesis and physical characterization of a new compound, NpRh 2 Sn, prepared by arc-melting under argon atmosphere. Rietveld analysis of the powder x-ray diffraction pattern reveals an orthorhombic, Fe 3 C-type structure, with lattice parameters that are the shortest among the An T 2 Sn series (An =…
In this paper, we propose a novel structure of quantum waveguide. In this structure we tailored the quantum wire by Gaussian Profile. Thus, the Dirac-Delta function potentials are weighted according to Gaussian distribution function. We studied the electronic transmission properties through this tailored quantum waveg…
Cadmium substituted Ni‐Cu Ferrites with the general formula Ni0.95−xCdxCu0.05Fe2O4 (x = 0.1, 0.2 and 0.3) were prepared by the standard double sintering ceramic method. The existences of single phase formation with crystalline size of 25–38 nm were confirmed from XRD measurements. The magnetic properties such as satur…
We propose and numerically investigate a kind of tunable and robust reflection-free waveguides based on a gyromagnetic photonic crystal (PC). The time reversal symmetry breaking of the gyromagnetic PC under out-of-plane dc magnetic fields gives rise to one-way edge modes in both the second and third band gaps. It is f…
This study investigated the bonding effectiveness of novel acryloyloxyalkyl and methacryloyloxyalkyl 6,8-dithiooctanoates (dithiooctanoate monomers) to precious metals and alloys. Eight kinds of dithiooctanoate monomers were synthesized in 16.09-39.34% yields. They were characterized and confirmed as new compounds usi…
