Template-free CuO nanorods were synthesized through a three-step chemical method with no water-insoluble materials. The first step included the preparation of a Cu-complex, which was obtained from dipicolinic acid, L-lysine, and copper nitrate. Then, as the second step, the obtained solution was allowed to be relaxed for a week to and formation of some blue single-crystals single crystals, whic...
Abstract: Nano pore Mordenite membranes were prepared on the outer surface of ceramic tubular tubes via hydrothermal synthesis and evaluated for dehydration pervaporation of water unsymmetrical dimethylhydrazine UDMH mixtures. Highly water-selective mordenite membranes were prepared and the optimum reaction condition was found to be 24 h crystallization time and 170 °C crystallization temperatu...
TRIP (TRansformation- lnduced- Plasticity) behavior is a powerful mechanism to improve mechanical properties. The basis of TRIP phenomena is the transformation of retained austenite with optimum characteristics (volume fraction, stability, size and morphology) to martensite during deformation at room temperature. Accordingly, the first requirement to obtain desired TRIP effects is to produce an...
In this study, the SrS nanopowder co-activated by Ce3+ and Sm3+ (SrS:Ce,Sm) was synthesized by the co-precipitation method. The transparent pellets were fabricated by mixing the SrS:Ce,Sm nanopowder and bisphenol-A epoxy resin as a crystal of the optically stimulated luminescence (OSL) dosimeter. The crystalline phase verification and also, the morphology of the synthesized nanopowder were inve...
BACKGROUND AND AIMS From Darwin's time onward, biologists have thought about adaptation as evolution toward optimal trait values, but they have not usually assessed the relative importance of the distinct causes of deviations from optima. This problem is investigated here by measuring adaptive inaccuracy (phenotypic deviation from the optimum), using flower pollination as an adaptive system. ...
Objective: To establish cell model of herpes simplex virus type 2 latent infection and reactivation in SHSY5Y cells. Methods: Effects of ACV on SH-SY5Y cells were observed after cells were treated with ACV concentrations of 20, 40, 60, 80, 100, 120, or 140 μmol/L, and also cells morphology was observed under phase contrast microscope after HSV-2 was inoculated into SH-SY5Y cells using MOI of 0....
Chemotherapy research highly prioritizes overcoming the multidrug resistance (MDR) in human tumors. Liposomal formulation of fluoxetine, as a fourth generation chemosensitizer, was constructed and characterized for percent entrapment, release profile, morphology, particle size, zeta potential and stability. Liposomes were prepared using different active loading techniques. The influence of diff...
In this study, we report removal of Diclofenac (DCF) through heterogeneous Fenton process using Fe-ZSM-5 catalyst. The parent catalyst was prepared by hydrothermal technique. Fe species were introduced by wet impregnation. Characterization of the catalysts was carried out using XRD, FT-IR, FE-SEM, N2 adsorption-desorption, NH3-TPD, and acidimetric-alkalimetric titration. The bimetallic catalyst...
This study is concerned with the synthesizing of Cu-Zn nano-ferrite particles in the laboratory applying simple techniques. The morphology of the synthesized nano-particles was analyzed using Transmission Electron Microscopy (TEM), and the minerals were identified using X-ray diffraction (XRD). The nano material was used to replace 1- 4 percent by weight of Portland cement in cement pastes and ...
The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...
