were seeded on top of this layer and allowed to grow into glial lineage.After the consistent growth and differentiation of both cell lineages individually and together, they were manually folded into a cylinder.Various histological and immunohistochemical parameters were assessed for the viability, growth and differen…
Molecular dynamics (MD) simulations and quantum chemical calculations were used to study the adsorption and the corrosion inhibition of three 3,4-dihydropyrimidin-2(1H)-ones (DHPM-1~3) on Fe(0 0 1) surface in pure water and 1 M hydrochloric acid solution. The MD simulation results indicate the three molecules are incl…
Abstract Optical microscopy (OM) and transmission electron microscopy (TEM) were used to investigate the effect of tempering temperature on the experimental extra‐high carbon steels. It is found that tempering reaction can reduce austenite content and influence the stability of the austenite. As‐normalized microstruct…
Crystalline silica shows strong, sharp signals at about 77 and 130 cm -1 in the inelastic neutron scattering spectrum that are missing or strongly different, broadened and shifted to lower frequency for the case of precipitated and fumed silica. The presence or absence of these signals is a sensitive signature of crys…
The electrical and dielectric properties of the compound C7H12N2[H2PO4]2 ⋅ 1/2H2O were investigated by the complex impedance spectroscopy, over a wide range of frequencies and temperatures, 600 Hz–5 MHz and 303–408 K, respectively. Besides, a detailed analysis of the impedance spectrum suggested that the electrical pr…
The angular dependence of an external magnetic field applied with an in-plane alternating pulse that induces a new direction of exchange bias (EB) is observed in an NiFe/IrMn bilayer. Depending strongly on the direction of the external field, EB field gradually orients along the external field with the increase in cur…
Nitric acid strontium and potassium silicate as raw material, the strontium silicate was synthesized preparation the strontium silicate was synthesized by chemical deposition method， and the strontium silicate was sintered for three hours in 850 °C, 1000 °C and 1150 °C. The effect of sintering temperature on phase com…
A photoassisted approach has been developed to synthesize a zinc indium oxide (Zn5In2O8)/oxysulfide composite through in situ sulfuration of vacancy-rich Zn5In2O8. It was found that vacancies have a considerable impact on the formation of the composite. The composite exhibited an increased photocatalytic H2 evolution…
This paper follows previous work regarding the settling velocity of non spherical particles in creeping motion.
Switched reluctance actuators have inherent advantages due to intrinsic simplicity and low cost, however also presents high thrust ripple due to double salient structure and nonlinear nature. In this paper, we address the direct instantaneous thrust control of a 3-phase 6/4 linear switched reluctance machine (LSRM), u…
To improve the efficiency of dye-sensitized solar cells (DSCs) by controlling dye adsorption on TiO2 surface, the effect of surface treatments on the properties of [NBu4]2[Ru(Htcterpy)(NCS)3] (black dye; [NBu4]: tetrabutylammonium cation; H3tcterpy: 4,4',4''-tricarboxy-2,2':6',2''-terpyridine) on nanocrystalline TiO2…
Permanent magnets are frequently adopted in small brushless machines for automotive applications. Normally anisotropic ferrites, but some research on bonded magnets is being carried on. Several types of magnetization can be proposed, involving different levels of complexity in the magnetization process. In the paper a…
The emerging of printed and organic electronics has been proven as a major trend in the last years. The only major commercial issue is represented by the organic light emitting diodes (OLED). In the current paper will be shown the results of electrical investigations of organic resistors based on poly(3,4-ethylenediox…
We report Y3Fe5O12 thickness dependence of spin pumping, spin current generation from magnetization dynamics, in magnetic insulator Y3Fe5O12/metal Pt bilayer films. We prepared different thickness Y3Fe5O12 films by the metal-organic decomposition method and measured the electromotive force due to the inverse spin Hall…
Abstract A lumped parameter type code, called HEPCAL, has been worked out in the Institute of Thermal Technology of the Silesian University of Technology for simulations of a pressurized water reactor containment transient response to a loss-of-coolant accident. The HEPCAL code has been already verified and validated…
This paper presents the design of a new application for parallel multi-cell converters. The aim is to setup a portable system that can inject a 12000 A current within 2s in the conducting core of a HVDC cable, and determinate the distribution of electrical space charge through the insulation using the Thermal Step Met…
Flux-reversal machine (FRM) has simple structure making it cost effective and suitable for mass production. However, there is notable permanent magnet flux leakage which deteriorates the characteristics of the FRM. The problem of irreversible demagnetization of permanent magnet is also important to the reliability of…
Partial discharge (PD) under a sequence of high-frequency pulse is one of the key factors which lead to premature failure of turn insulation of inverter-fed motors. Aging experiments for turn insulation samples under bipolar continuous square impulse voltage were done. The number and mean quantity of PDs under impulse…
Partial discharge (PD) analysis, based on measurement data, assumes that PD signals propagate inside a transformer winding from the PD source to the measurement points. In this paper, signals are injected via an external connection into specific points along the winding of a transformer experimental model. The measure…
연료전지 GDL 내의 물질전달에 관한 연구를 위하여 실제 GDL 을 고해상도 3 차원 스캐닝 장비를 활용하여 GDL 의 다공 구조를 실측하였다. 측정된 Data 의 노이즈를 제거하고 GDL 의 Carbon-fiber 구조를 전산해석이 가능한 모델로 자동적으로 형성하는 알고리즘을 개발하였으며, 이 모델을 활용하여 스택 체결 시 압축에 의한 GDL 구조 변형을 예측하고, Carbon-fiber 의 정렬 방향에 따른 변형 특성을 파악하였다. 또한, CFD 기법 중 하나인 VOF 모델과 Pore-network 모델을 이용하여 GDL 내부의 물거동 및 반응기체의 물질거동을…
