The reliability of p‐type ZnO thin films obtained by phosphorus implantation, using plasma‐immersion ion implantation, followed by rapid thermal annealing is reported. Also reported is the fabrication of a ZnO‐based homojunction light‐emitting diode. Low‐temperature photoluminescence measurements after six months show…
It is of significance to study the movement of solid - gas mixed flow of small particle size in the high electric field region for explaining such insulation accidents as contamination deposition, gap breakdown, unknown flashovers, and the like occurring on power line insulators surface. Based on artificial simulation…
Polycarbosilane (PCS) fibers have been made using a solvent which is a mixture of N,N-dimethylformamide (DMF) in toluene. Polycarbosilanes (PCS) obtained from NaBond with concentration 1.2 g/ml dissolved in solution toluene and N,N-dimethylformamide (DMF) was stirred gently for 24 h at ambient temperature. DMF was mix…
Double-chambered microbial fuel cells (MFCs) were used to investigate the effect of sulfate and sulfate-reducing bacteria (SRB) on electricity generation by molybdate inhibition coupled with PCR-DGGE technique. Results showed that low influent sulfate (< 1470 mg/L) improved power density and voltage, while higher sulf…
Growth kinetics of graphene and graphite layers on the surface of carbon-saturated rhenium has been investigated. The experimental data agree well with the results of the mathematical analysis of diffusion processes in the metal bulk with the participation of carbon atoms and the subsequent precipitation of carbon on…
In this paper, operator-based nonlinear temperature control for Cooling and Heat-retention System actuated by Peltier device is proposed. The main purpose is to construct a system which can use energy effectively with waste heat from Peltier device. Moreover, temperature control about the executing cooling and heat-re…
The present work investigates the effect of natural weathering on polypropylene (PP) composites containing short glass fibers and talc. The samples of PP composites obtained by injection moulding were submitted to nine months of natural ageing (from March to November 2012). It observed effects of climatic conditions o…
The discovery of quasicrystals played a revolutionary role in the condensed matter science and forced to renounce the dogma of the classical crystallography that the regular filling of the space by identical blocks is reduced solely to the Fedorov space groups. It is shown that aperiodic crystals, apart from the simil…
In this work, 99% purity zinc plates were anodized at potentiostatic conditions in distilled water at 25°C. The anodizing voltages were varied from 10 V to 30 V. The morphologies of the ZnO thin film were investigated by using scanning electron microscope (SEM) and the compositions were confirmed through the character…
An angular bandpass filter is designed. The structure is made of an array of chains of interconnected Split Ring Resonators. It may be applied for increasing directivity of antennas or reducing grating sidelobes. The main advantage over previous angular filters is the smaller thickness of the structure which is a smal…

This paper presents a model for fluid dynamic studies describing the bar-to-fiber interaction in refining processes. The approach is to introduce and validate assumptions for a deeper understanding of physical phenomena between refining bars in a micro-scale perspective. The model is based on Navier-Stokes equations i…
The optical detection of the crosslinking degree is very important to the forming quality’s on-line control of the hydrogel fibers and tissue engineering scaffolds in 3D printing process at room temperature. For the feature of small scale object, low contrast ratio and unclear outline of the crosslinked area, we proce…
Asymmetric rolling can be used in order to modify material properties and to decrease forces and torques applied during deformation. This geometry of deformation is relatively easy to implement on existing industrial rolling mills and it can provide large volumes of a material. The study of microstructure, crystallogr…
Freeze-thawed hybridized preparation and the biomimetic self-assembly technique were used to fabricate hydrogel as tissue engineered scaffolds for meniscus tissue. Because of the advantages of both techniques, they were hybridized together as an interesting preparation for hydrogel. Three molecular weights (high, medi…
Identification of pairing mechanism leading to ferromagnetic superconductivity is one of the most challenging issues in condensed matter physics. Although different models have been proposed to explain this phenomenon, a quantitative understanding about this pairing is yet to be achieved. Using the localized-itinerant…
nanoZrO2was modified by styrene coupling grafting method and then used as an additive to improve the protective performance of epoxy coating. Two kinds of coatings, neat epoxy coating and nanoZrO2/epoxy coating, were prepared and applied on Q235 carbon steel plates. The plates were submitted to salt spray chamber and…
Axisymmetric compression tests using Gleeble 3800 simulator were carried out to investigate hot deformation behaviors of an AA5083 alloy under high strain rate conditions. Sharp temperature rise and load cell ringing characterized by severely vibrational load responses were encountered at strain rates higher than 20 s…

We derive a structure model for icosahedral quasicrystals. The model is based on a statistical approach involving the concept of average unit cell. This approach enables limiting calculations to real space as opposed to higher-dimensional analysis involving to unphysical atomic surface modeling. We start with the thre…
