The idea of a new method for growing gallium nitride (GaN) epilayers on (100)-oriented silicon substrates is disclosed. It has been experimentally established that the formation of a special oriented thin (600 nm) buffer layer of aluminum nitride (AlN) by hydride-chloride vapor-phase epitaxy (HVPE) makes possible the…
The inverter is used as the power supply of modern permanent magnet synchronous motor (PMSM). The inverter may produce harmonics in inversion process and form harmonic currents in motor stator winding which can lead to factors against motor smooth operation such as torque fluctuating and winding heating. This article…
A novel chromo- and fluorogenic sensor, 4-(4-dimethylaminostyryl)-1-hexadecylpyridinium (DSHP) for lysophosphatidic acid (LPA) was successfully developed by incorporating a long alkyl chain into the cyanine molecule. DSHP shows excellent selectivity and high sensitivity towards LPA with a detection limit of about 7.09…
The design of biointerfaces that stimulate cell differentiation is a rapidly growing area of research that has significant implications in biomedicine. Biointerfaces that stimulate osteogenesis are typically composed, at least in part, of a biomimetic ceramic material, such as bioactive glass. Cell differentiation on…
In this paper a reaction-diffusion system for electrochemical material growth processes is considered, including an external sinusoidal forcing term for the PDE equation describing the morphology of the electrodeposit surface profile. The numerical approximation by the Alternating Direction Implicit (ADI) method based…
p-type GaP was systematically examined for photoelectrochemical water splitting. The influence of wet chemical etching and the difference of electrochemical deposition and physical vapor deposition of platinum were investigated. Therefore, each preparation step of GaP was studied by photoelectron emission spectroscopy…
Simultaneous determination of two important dopamine metabolites, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), at physiological pH was demonstrated for the first time using the electropolymerized film of a 3-amino-5-mercapto-1,2,4-triazole modified glassy carbon electrode.
BACKGROUND/AIMS: Chemicals that interfere with reactive oxygen species metabolism can act as potential candidates for the treatment of cancer. Some of the glucosides of citrus limonin inhibit the endogenously generated reactive oxygen species. The aim is to study the interactions of limonin with chemotherapy. METHODS:…

The aim of the present study was to mask the bitterness of propiverine hydrochloride (P-4) by converting it to propiverine free base. Fine granules comprising the free base, which was converted from P-4 by desalination, were prepared. By using Fourier transform infrared spectroscopy, thermogravimetry-differential ther…
In tissue engineering, biodegradable polymer materials with both high biocompatibility and high strength are very important as scaffolds for long term use. Therefore, in this research, we tried to prepare the three types of poly(L-lactic acid) (PLLA)/calcium phosphate (CP) hybrid composite for a scaffold biomaterial.…
There is evidence that the interaction of the α-ketol group of the Doxorubicin and Epirubicin anti-cancer drugs with Fe(III) generates hydroxyl radicals under aerobic conditions, causing cardiotoxicity in patients. Considering that the formation of DNA adducts is one of the main targets of Anthracycline drugs, we have…
To advance our understanding of molecular packing in glassy nanocomposites, we adopt a macroscopic granular model—comprising spherical inclusions dispersed in ball-chain polymers—and ascertain from measurements of the bulk density the partial molar sphere volume at small but finite sphere volume fractions. By systemat…
The purpose of this study is to investigate the influence of peening on the rolling contact fatigue (RCF) life of steel rollers. First, steel rollers were treated by three types of peenings to ensure the same surface roughness of peened rollers. One is the cavitation peening (CP) used a cavitating jet in water with an…
A novel self-healing hybrid-diffuser cesium reservoir photocathode is demonstrated. The model-driven design optimizes operating temperature to match diffusion and evaporation rates and maximize quantum efficiency of the cesiated tungsten surface. A sintered-wire tungsten emitter promotes surface uniformity. Cesium los…
This work describes an easy and flexible approach for the synthesis of 2D nanostructures by external composite field-induced self-assembly. Amorphous iron nanoplatelets with a large aspect ratio were prepared by reducing a concentrated FeSO4 solution with NaBH4 without any templates or surfactants under a magnetic fie…
In this work, the morphology, thermal and viscoelastic properties, deformation and fracture behaviour of a commercial vinylester resin modified with a biodegradable polymer was investigated. Flexural, impact and fracture tests were per-formed on the blends with different polycaprolactone (PCL) contents. They exhibited…
Friction stir processing (FSP) is a simple and effective technique to fabricate aluminium metal matrix composites with uniform particle distribution. In this investigation, AA6063/SiCp bulk composites were fabricated using FSP. Experiments were conducted to study the effect of the feed rate on particle dispersement, h…
The effect of SiO2capping on the optical properties of nanoparticles was investigated. The photoluminescence (PL) intensity was successfully improved by SiO2-capping. Sr2MgSi2O7:Eu,Dy nanoparticles were prepared by laser ablation in liquid. The SiO2capping was performed using the Stöber method with ultrasonication. Th…
The corrosion resistance of stainless steels in their delivered state and after an electrochemical surface treatment was studied by potentiodynamic voltammetry and microscopic analysis. The used electrolyte contained fluoride and sulphate ions. The polishing procedure varied with respect to current densities, polishin…
