In this study, ZnO films, prepared by Chemical Bath Deposition (CBD), are applied as the conductive layers for thin film solar cells. Zinc acetate is used as a source of zinc, and different proportions of ammonia solution are added and well mixed. The growth of zinc oxide films in reaction solutions is taken place at…
Distribution networks are an essential part of all water supply systems. Distribution system costs within any water supply scheme may be equal to or greater than 60% of the entire cost of the project. The reliability of supply is much greater in the case of looped networks. The pipe networks have concentrated outflows…
In this work, carbon nanotube/polycarbonate (CNT/PC) nanocomposites containing 1wt% CNT were prepared by a two-step method of twin-screw extruder mixing followed by injection molding at different temperatures. The microstructure, which has strong impact on the electrical properties of the composite, was affected by th…
Solid solutions Ni(Al, Mo, C) are formed via milling the Ni 2.8 Al 1 Mo 0.2 and Ni 3 Al 0.8 Mo 0.2 and graphite-containing Ni 2.8 Al 1 Mo 0.2 C (0.25, 0.5) and Ni 3 Al 0.8 Mo 0.2 C (0.25, 0.5) mixtures. In this case, some amount of Mo remains beyond the solid solution. Graphite added to a starting mixture decreases th…
The problem being investigated was to develop an economical, environmentally friendly, and quality panel made from recycled plastics. The objective of this work was to contribute to decontaminating the environment, and to solving the housing shortage in our country. The developed products were panels for housing and e…
Sr-doped lanthanum manganite (La1-xSrxMnO3) is characteristic of thermochromic, which can act as a smart thermal control material used in the variable-emittance devices. In the present study, La1-xSrxMnO3 thin films were prepared on MgO(100) substrates by pulsed laser deposition, and the effect of Sr-doping (x = 0 ~ 0…
To completely remove the water freezing in the outdoor pipes of hydroelectric plants and water supply systems and to prevent the water cooling in the pipes of domestic hot water supply system at low consumption or if water is stationary, could be used some modern regulation systems for water temperature. Also, radiant…
In this work, electron beam modified heterogeneous composites of isotactic polypropylene (PP) with chlorinated polyethylene (CPE) have been investigated. The PP/CPE blend composites with an excess of elastomer (30/70 wt%) have been modified with trimethylolpropane triacrylate (TMPTA) and bisphenol-A-dimethacrylate (BP…
Nano zinc titanate ceramics are prepared using a conventional solid state method. The obtained compacts are sintered at 800, 900, 1000 and 1100 °C for 3 h. The prepared compacts are analyzed using X‐ray diffraction (XRD) and scanning electron microscopy (SEM) for structural and microstructural studies. Based on the X‐…
Abstract This paper proposes a new simulation approach for the AC magnetic contactor using the electromagnetic transients program (EMTP). The duality transformation technique is applied to convert a magnetic model into an electrical model. The great advantages of the proposed model are its capability of being directly…
Objective(s): Skin extracellular matrix, which contains type I and type III collagens, is involved in skin development. The aim of this study was to investigate type III collagen distribution pattern as well as its changes during pre and post-natal skin morphogenesis in rats.
A facile and simple method was proposed to control the size and shape of the MgO nano structures with high surface area in the presence of efficient and cheap templates like PEG 200, PEG 600, PEG 4000 and sorbitol at low temperature within a little time. Nano rods and Nanoparticles have been achieved by applying these…
Paper, film, and metallic webs have designed surfaces. Process engineers design these surfaces to ensure they will coat or print correctly. In some cases, such as tissue, the manufactured surface is designed to provide softness. After the web is formed, care must be taken to maintain the web surface for the intended u…
The main purpose of this article is to study the effect of adding attapulgite nanoparticle into the polymer on micro-crack toughing. Commercial softwares Abaqus and ANSYS were utilized to simulate the stress field and the crack expanding condition in the attapulgite/epoxy composite. The pure polymer and the nanopartic…
It is a promising treatment strategy to use a nanoparticlebased drug delivery system for cancer patients, which can simultaneously deliver multiple drugs or genes in combination with therapy to induce synergistic effects and suppress drug resistance to the tumor. In this study, cationic nanostructured lipid carriers…
Colloidal crystals are two-dimensional (2D) or three-dimensional (3D) ordered arrays of micron or sub-micron sized monodisperse colloidal particles. Because of the presence of unique periodic structures, colloidal crystals possess many fascinating properties which have important applications in preparation of ordered…
This study reports the synthesis of bismuth ferrite ceramics (BiFeO3, BFO) by the sol-gel method and the effect of different sintering temperatures (800 °C, 820 °C, 850 °C, 880 °C, 900 °C) on the crystal structure, morphology, dielectric properties and ferroelectric properties of the bismuth ferrite ceramics. It is ob…
In this paper, semi-empirical formula for the bulk modulus (B in GPa) and shear modulus (G in GPa) of perovskite structured solids are elaborated in terms of lattice constant (a in Å) and product of ionic charges (Za Zx) of the bonding. Values of bulk modulus, of the group ARh3X, (X = B and C) perovskite-type material…
Phosphatized and phosphatic small shelly fossils are a major source of information concerning the evolution of animals during the early Cambrian. Although progress has been made in understanding some of these fossils, many remain enigmatic, both with regard to their phylogenetic affinities and the overall morphology o…
