It is shown that the cathode products of electrolysis of melts based on a eutectic mixture of sodium chloride and lithium fluoride as well as melts based on sodium tungstate in which dissolved oxides of molybdenum (VI) or tungsten (VI), molybdate, tungstate and lithium or sodium carbonates are molybdenum, tungsten, th…
In this paper, crystalline iron-nickel alloy nanostructures were successfully prepared from two cationic pyridinium derivatives as soft templates in solution. The crystal structure and micrograph of FeNi alloy nanostructures were characterized by X-ray diffraction, scanning electron microscopy and transmission electro…
In this work the effect of Ca doping on the structural and electrical properties of BaTiO3 thin films prepared by sol- gel method was investigated. The XRD patterns revealed the perovskite structure of BCT thin film shows tetragonality decreases with increase of Ca concentration at Ba-site. AFM images show dense, homo…
A novel catalyst‐free methodology has been developed to prepare few‐layer hexagonal boron nitride nanosheets using a bottom‐up process. Scanning electron microscopy and transmission electron microscopy (both high and low resolution) exhibit evidence of less than ten layers of nanosheets with uniform dimension. X‐ray d…
The molecular and electronic structure of the 1:1 charge-transfer complex between ferrocene (Fc) and zinc porphyrin (ZnP) are investigated with the aid of dispersion-corrected density functional theory (DFT) calculations. Four stable configurations were obtained, two with the Fc molecule laying on the ZnP plane and th…
Quasi-monocrystal ZnO film grown using the hydrothermal growth method is used for the fabrication of Cu2O/ZnO heterojunction (HJ) ultraviolet photodetectors (UV-PDs). The HJ was formed via the sputtering deposition of p-type Cu2O onto hydrothermally grown ZnO film (HTG-ZnO-film). The effect of annealing temperature in…
Plant extracts have become important as an environmentally acceptable, readily available and renewable source for wide range of inhibitors. Therefore, inhibition of the corrosion of mild steel in hydrochloric acid solution and cooling water was carryout by the root extract of Miswak (Salvadora persica) has been studie…
The present study investigates the effect of different molten metal processing methods on the modification of primary silicon and the microstructure and mechanical properties of hypereutectic Al-18wt%Si alloy. The effects of melt treatment with the addition of electromagnetic vibration, AlCuP, bubbling of argon gas an…
Cu/HfO x /n + Si devices are fabricated to investigate the influence of technological parameters including film thickness and Ar/O 2 ratio on the resistive switching (RS) characteristics of HfO x films, in terms of switch ratio, endurance properties, retention time and multilevel storage. It is revealed that the RS ch…
This study included two parts: (1) the structural characteristics, chemical stability, thermal expansion coefficient (TEC), chemical bulk diffusion coefficient ( D chem ), chemical surface exchange coefficient ( k chem ), electrochemical performance and single cell performance for LaSrCo 1.6 Cu 0.4 O 5+δ as an interme…

Apesar do sol enviar em uma hora mais energia do que o planeta Terra consome em um ano, essa nao e a fonte de energia mais importante do planeta. Instalar um sistema fotovoltaico ainda e caro, e a eficiencia da maior parte dos modulos comerciais e de apenas 15%. Em geral, esses modulos sao de silicio mono ou policrist…
Tensile properties of Al-Mg-Si alloy with Mg-Si clusters was compared with that with β″ precipitate with the same strength. It was found that the elongation of the alloy with Mg-Si cluster was greater than the alloy with β″ precipitate because of high work hardening rate, in particular at large strain region. Decompos…
We have synthesized and studied the boron doped ZnO nanostructure thin films. The crystallinity of undoped and boron (B) doped ZnO (BZO) has been studied from XRD results. Using the Debye-Scherrer Formula, the grain size has been evaluated, which was found to decrease with increased doping concentration. The optical a…
New UV-stimuli-responsive liposomes composed of two different kinds of phosphates, dipalmitoylphosphatidylcholine (DPPC) and azobenzene (Az)-containing amphiphilic phosphates were fabricated. The release behavior of calcein within the phospholipid vesicle lumen was studied by monitoring the changes of fluorescence int…
Various construction waste is generated in large quantities and can be used in different ways. The authors examined several construction sites, defined the range of construction waste and their proportion in overall total. For this research concrete waste in construction sites have been investigated. The paper present…
The influence of the nature and the maintenance of the secondary supplier, the contents and the nature of the predecessor of palladium on catalytic activity of Pd/MeO x /Ni-Al/HC catalysts in the reaction of deep oxidation of methane is considered in the work. The secondary supplier was put with the method of a plasma…
Gas modulation experiments in H-mode plasmas featuring a scan in collisionality to study particle transport and sources at the plasma edge have been carried out on JET [5]. The local electron density response to the gas injection was measured with a high resolution reflectometry [6] along the midplane and with Lithium…
The formation of large and morphologically uniform Ce(III)-doped calcium hydroxyapatite (CeHap) particles by a forced hydrolysis method using Ca(OH)2-Na5P3O10-CeCl3-mixed solutions was investigated and the precipitated particles were characterized by various methods. The ellipsoidal secondary particles with ca. 115 nm…
The issue of sample quality is important in regards to determining reliable and representative soil parameters for fine-grained soils. In the literature, there exist several assessment criteria that can be used to assign a degree of confidence to laboratory parameters, such as the strength and stiffness. In this paper…
