Along with our country " west-east electricity transmission " project and UHV projects, HTV-silicon rubber with superior properities has been more and more widely used in the western regions of China.The paper focus on hami to zhengzhou ±800kV UHV DC transmission project which in hami HTV-silicon rubber insulators agi…
The optimum preparation conditions of the macromolecule flocculant-mercapto-acetyl chitosan (MAC) using orthogonal experiment were investigated, and its performances were tested by using the wastewater containing turbidity and/or heavy mental ions such as copper, cadmium, mercury, nickel ions as the target in differen…
Poly (vinylpyrrolidone)-anchored iridium nanoparticles (PVP-Ir) were prepared via the reduction of H2IrCl6·nH2O in ethanol/water mixtures. The catalytic properties of the colloidal nanoparticles that dispersed on Al2O3(PVP-Ir/Al2O3) were investigated in the selective hydrogenation ofp-chloronitrobenzene (p-CNB) top-ch…
The furnace slag are the by-products of the steel industry, the main ingredients are the oxide of calcium, alumina and magnesium, and some silica. Slag used as concrete aggregate could cause the problem of the volume expansion of concrete. The expansion problem may be produced by ASR or free calcium oxide and magnesiu…
Lots of loess sediments, mostly located at the Eastern Songnen Plain, have been deposited through the whole Quaternary period. In order to determine their sources, samples were collected from a number of representative areas, such as the dust loess, river sediment of the Songhua River and the Horqin sandy land. Heavy…
Pd-coated copper wire bonding is getting more practical applications in electronic packaging because of advantages, such as ease of use, better bonding performance and reliability. ENEPIG (Electroless Ni Electroless Pd Immersion Au) is a prevalent surface finish technique that can realize more flexible substrate desig…
For the characterization of objects on the micro-and nanoscale scanning electron microscopy (SEM) and atomic force microscopy (AFM) are common imaging techniques. Due to the different technical approaches of both methods they provide different information about the sample so a fusion of AFM and SEM images into a singl…
A tunable hyperchromatic system for confocal imaging is presented. The system, consisting of a magnetically-actuated, hydraulically-tunable concave membrane lens in combination with a positive diffractive lens, functions as a tunable filter in the 450 - 900nm spectral range. A spectral width of 15nm is demonstrated ov…
The growing demand of energy efficient systems is increasing day by day, therefore hybrid electrical energy storage devices is the need of the hour. In electrically operated vehicles and renewable power generation systems the energy storage is a very critical component. Ultra-capacitors are an emerging technology whic…
In this study, the surface-treated fly ash particles, ranging from 0 to 50 percent of weight were used as fillers added to the unsaturated polyester (UP). The fly ash (FA) particles were characterized using Mastersizer 2000 particle size analyzer, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The re…
We describe the development of apparatus for measuring of electrical conductivity and Seebeck coefficient with high precision from 85 K to 1,200 K. Electrical resistance was measured by means of four-point probe method as a function of temperature. The temperature below 400 K was measured by using type T thermocouple…
An automated laboratory based X-ray beamline with a multi-capillary sample chamber capable of undertaking small angle X-ray scattering measurements on a maximum of 104 samples at a time as a function of temperature between 5 and 85 °C has been developed. The modular format of the system enables the user to simultaneou…
Yttrium Iron Garnet (YIG) granular composite materials in the high particle content show negative permeability spectra under external magnetic field in the microwave range. In this study, the complex permeability spectra (μr= μr' - jμr") of 56.2 vol.% YIG composite under external dc field have been analyzed using a pe…
Czochralski growth of cm size decagonal AlCoNi single crystals from Al-rich high-temperature solutions is described using native seeds oriented parallel to all symmetrically dierent crystal directions. Morphological observations allow rst hints with respect to anisotropic growth rates. But only classical detachment ex…
In this study, bamboo ply panel (BPP) was exposed to 5 kinds of accelerate aging cycles in order to assess its durability under extreme conditions. Meanwhile, outdoor weathering, as a comparison, was carried out for 36 months with the objective of evaluating humidity resistance by means of testing modules of rupture (…
The possibility of using hollow-core photonic crystal waveguides as biological sensors is shown. The influence of the glucose concentration in solutions introduced into the waveguide core on the transmission spectrum of photonic crystal waveguides is shown. Two possible methods of determining the glucose concentration…

Hexagonal boron nitride (h-BN), a structural analogue of graphene, is an insulating material with a large band gap.The combination of graphene and h-BN is expected to lead to a wide variety of applications.Thus, the demand for large-area and high-quality growth of h-BN is increasing.This article describes a novel and…
The nature and dimensions of disordered regions emerged in n-Si single crystals irradiated with high-energy (25 MeV) protons have been studied by carrying out Hall measurements of their electrophysical parameters. Specimens fabricated with the use of the zone-melting technique and doped with phosphorus to a concentrat…
