Fiber porous ceramics are the excellent candidates for a variety of applications, and thus, their research is a hotspot in recent years. In this study, carbon fiber reinforced phosphate porous ceramics composites were prepared by acupuncture and in-situ solidification vacuum-assisted liquid-phase infiltration method.…
In this paper, a Repetitive control (RC) structure of linear switched reluctance motor (LSRM) is proposed with DSP control implementation. Repetitive control law uses errors from the last period to adjust the new command fed into a system. Moreover, a low pass zero phase filter (ZPF) is associated with RC to cut high…
Silicon based chalcopyrite (with the compounds composition I(B)-III(A)-VI(A)2) hetero-junction solar cells have been reported with the potential of high conversion efficiency theoretically. The hetero-junction solar cell with PNN+structure is fabricated as: front metal electrodes/transparent conductive oxide (TCO)/ p-…
A Si-rich silicon carbide (Si1-xCx) based p-n junction photovoltaic solar cells is demonstrated by growing the non-stoichiometric SixC1-xfilm with plasmas enhanced chemical vapor deposition (PECVD) at low RF plasmas powers. By decreasing RF plasma power from 100 to 20 W at medium substrate temperature of 500°C, the X-…
PURPOSE: Micro CBCT scanners have a broad spectrum of applications in medicine and material science. However, CBCT suffers from scatter radiation and spectral effects such as beam hardening (BH). In this work an iterative BH- and scatter-correction algorithm was developed using Monte Carlo (MC) methods. METHODS: Two μ…
Abstract We report a high performance solution processed oxide thin film transistor (TFT) produced at the maximum temperature of 230°C. Chloride derivate precursors were used for making Indium Zinc Tin Oxide (IZTO) as channel layer and Aluminum Oxide (AlOx) as gate insulator. The IZTO TFT exhibits field‐effect mobilit…
Tin mono-sulfide (SnS) thin films have been grown by molecular beam epitaxy (MBE) on two different substrates, GaAs (100) and soda lime glass at 400°C. High resolution X-ray Diffraction (HXRD) and Scanning Electron Microscopy (SEM) are used to characterize the structural properties of the as grown SnS films. By introd…
In this paper, we focus on the phase behaviors of talc minerals by carbothermal reduction (CR) method. The effects of temperature and carbon addition are both discussed in our work. In the experiment, acid-leaching talc was employed as raw material, carbon coke powders were adopted as reducing agent. The XRD results s…
Characteristics of new reconfigurable graphene device with Metal/ Ferroelectric (PVDF-TrFE)/Graphene (MFG) stack is presented. Key features include programming speed <; 100nsec, retention up to 1000sec, endurance upto 1000 cycles and more than 775% on/off ratio. While memory like functionalities are primarily presente…
A facile method to selectively synthesize nano-scaled Gd2O3 with different morphology such as nanosheres and nanorods has been developed in our report. The precursors GdOHCO3 can be prepared by a two-step hydrothermal process via homogeneous generation of hydroxide ions through the hydrolysis of urea, and the formatio…
Cover: Polymers may contain several active, dead, and dormant radical centers at the same time, which results in a multidimensional modeling problem. A model of the network formation kinetics during the nitroxide-mediated radical copolymerization of vinyl/divinyl monomers is presented in this work using a multifunctio…
This paper studied the mechanical behavior of composite yarn fabrics and pure cotton yarn fabrics with the conditions of small deformation, then making some comparison. KES-F (Kawabata Evaluation System for Fabric) system was used in the research process. The study shows that the fabric samples made of composite yarn…
Use starch, corn meal and activated carbon as pore-making agent, Ni-YSZ/YSZ composite ceramic green body was prepared by multiple gel-tape casting with acryloyl ammonium-polyvinyl alcohol. The specimen was sintered at 1450°C for 4h, then reduced in hydrogen atmosphere at 800°C for 4h, Ni-YSZ/YSZ composite ceramic disk…

The authors mainly use the two-dimensional finite-difference time-domain method to study the effection on image resolution of target detection and imaging when active impurities are introduced to negative refraction photonic crystals (NR-PC) flat lens. It is demonstrated that because of the influence of the mini-forbi…
Electromagnetic stirring (EMS) is an important method to homogenize the hard phase of the cladding layer. Rotary Permanent magnet electromagnetic stirring (PEMS) is adopted during the experiment. The changes of heat affected zone, solidification character, microstructure and hardness of TA15 Laser Metal Deposition (LM…

SrAl2O4:Eu2+, Dy3+ long afterglow phosphors were prepared by combustion synthesis and the influence of PEG dosages of the long afterglow phosphor on the luminescent properties was studied. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence spectroscopy (PL) and…
An experimental device is designed to control slag entrapment of molten steel with ElectroMagnetic Brake(EMBR). Mercury was taken to simulate the liquid steel flow in the mold. The factors which affect slag entrapment with EMBR are studied, such as position of magnets, distribution of magnetic flux density and submerg…
Effect of CMCS on the thermal stability of natural rubber(NR) was studied by means of TG-DTG,and the decomposition activation energy(Ea) was calculated through Flynn–Wall–Ozawa (FWO) method in the paper.The results showed that the Ea of NR mixed with CMCS was higher than that of ammonification NR,and the thermal stabi…
