A green synthetic route is reported for quickly synthesis of highly luminescent CdTe-Mn/ZnS quantum dots (QDs) in aqueous solution. Glutathione (GSH) was used as capping reagent and thioacetamide (TAA) as sulfur source for growth of ZnS shell on the CdTe-Mn QDs. At the optimum reaction conditions, the results indicate…
To develop a new industrial briquette composite binder, response surface methodology was used to arrange experiments, with modified peat(MP），mixed wastes(WS)，modified clay 2(C2) and clay 1(C1) as raw materials. The experimental data was firstly processed utilizing the method of multi-factorial total probability formul…
NiCuZn ferrites were prepared through conventional solid-state method. The effects of the sintering aids such as Bi2O3 and glass on the DC bias superposition characteristic of NiCuZn Ferrites were investigated. It was apparently discovered that when the glass and the Bi2O3 were doped together, the grain size was distr…
A procedure for synthesizing AgFeAsSe 3 and AgFeSbSe 3 is presented, and their electric and magnetic properties are investigated over a wide range of temperatures, pressures, and magnetic field variation. At 100–400K, the samples are characterized by semiconductor properties. Under pressures of ∼25 and ∼24 GPa, the el…
Nano-magnesium oxide, MgO film was successfully prepared at various annealing temperatures (400, 450, 500 and 550°C) by using sol-gel method. The behaviour of the MgO as a dielectric layer was investigated in term of its electrical behaviour, relative permittivity and structural properties. The leakage current density…
We investigated the effect of immersion time on optical, electrical properties and surface morphology of nanostructured Aluminium (Al) doped Zinc Oxide (ZnO) thin films prepared by immersion technique. UV-Vis-NIR spectra indicate that the transmittance of the samples decrease with immersion time. Electrical properties…
Iodine doped amorphous carbon (a-C: I) thin films were prepared by using Thermal Chemical Vapor Deposition (CVD) with deposition temperature ranging from 5000C to 7000C. The physical and electrical properties of deposited a-C:I thin films were characterized by Raman spectroscope and Solar Simulator system. The presenc…
This paragraph deploys high temperature non-vacuum methods, and vanadium pentoxide powder, carbon black and graphite is used to make VN. The result shows that the particle sizes of these three raw materials vary greatly. When they are mixed with a certain proportion, the kinetics condition of reaction is greatly impro…
The microstructure of the inorganic fullerene-like WS2 was analyzed by scanning electron microscope (SEM) and high-resolution transmission electron microscopy (HRTEM) in this work. The results indicate that the diameter of the WS2 particles is around 60~120 nm. The WS2 consists mainly of hollow polyhedral structures w…
Transparent thin film transistors (TTFT) were fabricated on N+ Si wafers. SiO2, Si3N4/SiO2 and Al2O3/SiO2 grown on the wafers were used as gate insulators. The rf magnetron sputtered zinc tin oxide (ZTO) films were adopted as active layers. N+Si wafers were wet-oxidized to grow SiO2. Si3N4 and Al2O3 films were deposit…
In order to have a better understanding the wearability of bamboo pulp fabric and enhance the research and development level of this kind of products, the fabric performances such as the strength, elongation, air permeability, moisture permeability have been test and discussed in this paper. The results shown that: th…
The concept of plasmonic nanoantennas is based on using nano-structures to confine light in nanometer scale. In this paper, we study the scattering property of ellipsoidal particles at optical frequencies. Numerical results illustrate how the Extinction Cross Section of ellipsoidal core-shelled nanostructures depends…
Au-catalyzed growth of nanocrystalline Si by pulse jet chemical vapor deposition has been investigated. Au thin film was first deposited on thermally oxidized Si(100), then CH3SiH3 pulse jets were irradiated onto the Au/SiO2/Si(100) surface. The irradiation of the CH3SiH3 jets at 1150 °C resulted in circular patterns…
In order to study the details of deformation and microstructures evolution during rolling and annealing process, magnesium alloy AZ31 blank, cast by unidirectional solidification and then sliced, has been rolled at high temperature with one pass deduction of 50% in a 2-high mill. During the rolling process, the mill w…
In the 1990s, TN International designed the RD26 package to transport waste, principally α emitters, from various nuclear plants. The RD26 packaging essentially comprises a cylindrical body, a lid, a shock absorber cover and a handling pallet; the cavity (diameter, 513 mm; length, 780 mm) can receive a 120 L drum. The…

Reflectors are common structures utilized in antenna system to obtain specific directive radiation or to enhance antenna gain. It is quite desirable to construct reflectors with planar or low-profile features in many applications. In this paper, we present the design of two kinds of low-profile planar electromagnetic…
