Crystalline quality of pulse-laser annealed poly-Si films on YSZ layers is further improved by a new two-step irradiation method, in which a-Si films were irradiated using two kinds of energy. Firstly, they were irradiated at low energy for a short time to generate nuclei, following by irradiation at high energy to sp…
THz optical constants were measured for layered clay minerals with different chemical compositions (kaolinite, hectorite and montmorillonite). Corresponding hybrid materials were prepared after chemical modification of parent clays with intercalation (using e.g. alkylamines or amino acids). The THz-TDS spectra showed…
Adjusting the proportion of gases and stirring rate and other parameters, the value of pH, electrical conductivity, electrode potential, temperature of the system were tested online under different parameters. According to the results of scanning electron microscopy , the coating effect of different reaction stages an…
The regularities of the copolymerization of styrene (Sr) with vinyl acetate (VA) in a construction petroleum bitumen (CPB) medium are studied. It is established that, in the bitumen medium, the superiority of styrene in terms of reactivity when compared to vinyl acetate is not expressed as critically as in the case of…
Linxia basin is a late Cenozoic fault-block basin along the border between the Tibet plateau and the Loess plateau in Northwestern China. Its formation and sediments’ record may be directly affected by the structural dynamics and the uplift of the Tibet Plateau. For this reason, we studied the mineral characteristics…
In this report, the micro structure of PI/ TiO2films with different components prepared by in-situ polymerization method is researched by XRD, TEM, synchrotron radiation SAXS. Its micro structure characteristics include nano-particles distribution, PI molecule chains spacing and interface layer thickness. The experime…
As a new integration and packing technology, the low temperature co-fired ceramic (LTCC) technology attracts close attention for its excellent advantages such as high speed transfer characteristics, high reliability, miniaturization, etc. However, the sintering shrinkage of LTCC substrate always affects the practical…
What we present is fabrication of a novel TiO2/CNT based transistor. Vertically aligned CNTs have been grown on a silicon substrate. The CNTs were then encapsulated by TiO2nanoparticles, which act as the gate material and are responsible for controlling the field emission current from CNTs. The field emitted electron…
This paper aims to investigate the performance of a new three-parameter damage mechanics model which describes three basic damage mechanisms of quasi-brittle solids: tension, shear, and hydrostatic compression. The stress is first decomposed into its positive part and negative part, and then the latter is further deco…
We introduced a carbon nanotube electron beam (C-beam) exposure technique for thin films for display devices. As an electron source, the CNT emitters were placed on cathode electrode. Electrons through gate mesh, with higher accelerated energy, impact thin film on the anode plate. For display device application, amorp…
The porous sol-gel silica thin films were prepared on silicon substrate by the dip coating process. The surface roughness and microstructure of the film was measured by optical microscopy and AFM .Coating thickness and refractive index were measured by ellipsometry method. Influence of withdrawal speed and concentrati…
Analysis of the scope for more efficient bar rolling is considered; a method of rapid analysis is outlined. By this means, the geometric parameters of the rolling pathways may be represented by alternative groups of repeatedly transformed dimensionless factors, and the results of repeated transformation may be statist…
A design of epsilon-near-zero (ENZ) medium consisting of metallic wires was presented in this paper. According to the theory, structures proposed here could squeeze electromagnetic (EM) energy and let EM wave tunnel through with negligible loss. We verified the tunneling effect in both two dimensional (2D) and three d…
The study investigates the influence of different fraction of Mg2B2O5 whiskers (5, 10, 15 and 20vol.% ) on the microstructure of the hot extruded composite as well as on the mechanical properties in the same condition. The results indicate that the process is available for producing the composite, image analysis shows…
We investigate arrays of optical antennas coupled with fluorescent emitters. We specifically explore two limiting regimes - one where the antennas are separated by a distance equal to or larger than the wavelength, allowing the formation of hybrid modes called lattice surface modes, and the other where the period of t…
Tg and crystallinity of trilobal cationic dyeable polyester (THCDP) and poly(ethylene terephthalate) through X-ray diffraction and differential scanning calorimetry were tested respectively, and the results manifest that lower Tg and percent crystallinity of THCDP contribute to lower dyeing temperature. The dyeing beh…
Six models of typical insulation defects are designed and lab-simulated system used for partial discharge (PD) detection of cables and accessories has been constructed to study PD characteristics of internal insulation defects in 110 kV XLPE cable system. By employing CPDM, a kind of on-line PD detector, test data of…
In this paper, four original full typical UHF partial discharge signals are measured by using log-periodic antenna in 3-meter anechoic chamber environment.

We present a nanoparticle array (NPA) to visually predict the optical dielectric constant of a thin layer of powder. We validate the proposed concept with the full-wave simulation of a design example.
Nonlinear ferromagnetic hysteresis analysis is conducted using the three-dimensional time-domain finite element method combined with the inverse Jiles-Atherton (JA) vector hysteresis model. The second-order wave equation is formulated through the magnetic vector potential in the time domain. To incorporate the nonline…
