This paper presents a typical application for a newly developed thermoelectric energy harvesting system. The proposed solar thermoelectric generator (TEG) operates with phase change material (PCM) day and night. An energy management system was connected with the TEG to increase the output voltage while the harvested p…
The aim of this study was to find out an application of the municipal waste incineration materials and try to use them as a replacement for the natural ones. MSWI (Municipal Solid Waste Incineration) bottom ash (BA) was used as partial/total replacement of siliceous sand in CEM II based mortar. Three size fractions of…
Estimation of longitudinal change in beta amyloid (Aβ) burden may be important to assess disease progression or response to therapy. Using ADNI florbetapir data we evaluated whether measurement of longitudinal amyloid accumulation in Aβ positive subjects can be improved with an alternative reference region. 187 subjec…
The flow stress behaviour of Ti-5553 titanium alloy during hot compression deformation was studied by thermal simulation test at the deformation temperature of 750–900°C and the strain rate of 0·001–0·1 s−1 on the Gleeble-3500 thermal and mechanical simulator. The results show that the flow stress was controlled by bo…
High strength steel has a prosperous future in catering the needs of marine applications especially the tapping of deep sea resources. The use of high strength steel will reduce the weight of steel structures and reduce the environment burden for the production of materials. Thus it is necessary to study the problems…
The spontaneous emission (SE) of InGaN/GaN quantum well (QW) structure with silver(Ag) coated on the n-GaN layer has been investigated by using six-by-six K-P method taking into account the electron-hole band structures, the photon density of states of surface plasmon polariton (SPP), and the evanescent fields of SPP.…
Abstract First‐principles calculations are carried out to examine the adsorption of acetylene over the Pd (111) surface. A hydrogen adsorption system is initially investigated to confirm the reliability of the selected calculation method. Adsorption energies, Mulliken‐populations, overlap populations, charge density,…
The article presents the research results of modifying antifreeze influence on the pore structure formation of dry mortars in terms of adhesive and base layers of external thermal insulation composite systems within different temperature regimes of hardening.
Gouging is a damage mechanism that occurs on the surface of rails of electromagnetic railgun. The disadvantages of gouging include lowering efficiency of railgun system, decreasing life of rails and reducing direction accuracy of projectile. According to configuration and dimension of the experimental arrangement, ana…
Heat-assisted magnetic recording (HAMR) has attracted increasing attention as one of the most promising future techniques for ultra-high-density magnetic recording beyond the current limit of 1 Tb in(-2). Localized surface plasmon resonance plays an important role in HAMR by providing a highly focused optical spot for…
We reported large size amorphous Indium-Gallium-Zinc-Oxide and Indium-Tin-Zinc-Oxide thin film transistors active-matrix organic light-emitting diode television development history in AUO. The Gen6 threshold voltage uniformity can lower than 1.0V. Amorphous Indium-Tin-Zinc-Oxide thin film transistors show a higher mob…
The structural X-ray analysis of the phase-structure state of the Pd-In-Ru alloy foil after two types of hydrogenation and relaxation (during 8200 h) was carried out. The broadening of the distibution function of the coherent scattering regions (CSRs) with respect to the concentration of indium atoms in the alloy matr…
We investigate the stopping power of the multi-MeV protons moving in the hot dense deuterium-tritium plasmas mixed with beryllium (Be), which is important in inertial confinement fusion experiments. It is shown that with increasing the density of Be, the stopping power of the proton also increases with the peaks shift…
The temperature dependence of the internal quantum efficiency (IQE) of blue InGaN-based light emitting diodes is analyzed both experimentally and theoretically with a drift-diffusion transport model. A high-performance reference structure and two improved epitaxial designs are compared at different operating temperatu…

The Alexander–Haasen model was originally used to model the multiplication of the mobile dislocations in crystalline silicon. Here, we extend this model for studying multiplication of basal plane dislocations (BPDs) in single-crystal sapphire. By fitting the Alexander–Haasen model to experimental data, we find that th…
Based on numerical results from density-functional perturbation theory calculations, we show that the magnetic spin transition in Fe 2+ -rich MgSiO 3 perovskite can be identified as changes in the powder X-ray diffraction (XRD) pattern and the vibrational spectra. In particular theory predicts how the symmetry breakin…
Quasi-static indentation tests were carried out to investigate the mechanical responses of sandwich panels with composite face sheets and aluminum foam core. The energy absorption, specific energy absorption and energy-absorbing effectiveness factor of rigid-supported composite sandwich panels were evaluated and compa…
L1 0 FePt nanocomposite with high magnetocrystalline anisotropy energy has been extensively investigated in the fields of ultra-high density magnetic recording media. However, the order—disorder transition temperature of the nanocomposite is higher than 600 °C, which is a disadvantage for the use of the material due t…
To intruduce conductive biomaterial into liver tissue engineering, a conductive nanofiber scaffold, polypyrrole/poly(lactic-co-glycolic)acid(PLGA), was designed and prepared via electro-spinning and oxidative polymerization. Effects of the scaffold on hepatocyte adhesion, viability and function were then investigated.…
