Abstract Miscibility, isothermal melt crystallization kinetics, spherulitic morphology and growth rates, and crystal structure of completely biodegradable poly(ε‐caprolactone) (PCL)/tannic acid (TA) blends were studied by differential scanning calorimetry, polarized optical microscopy, and wide angle X‐ray diffraction…
Current views of the mechanism of the catalytic isomerization of α-pinene were discussed. Catalytic systems, modifiers, process conditions, and the effect of process conditions on catalytic activity and on the target-product (camphene, dipentene) selectivities of the process were considered. α-Pinene isomerization was…
The aim of this work is to study the effects of hydrogen absorption on mechanical properties of pipe API 5L X70 steel. This study is conducted in special soil solution NS4 with pH 6.7 It show that the tensile properties like yield stress, ultimate strength and elongation at failure reduced under hydrogen embrittlement…
Abstract Precursor of nanocrystalline Zn 0.5 Ni 0.5 Fe 2 O 4 was obtained by grinding mixture of ZnSO 4 ·7H 2 O, NiSO 4 ·6H 2 O, FeSO 4 ·7H 2 O, and Na 2 CO 3 ·10H 2 O under the condition of surfactant polyethylene glycol (PEG)‐400 being present at room temperature, washing the mixture with water to remove soluble ino…
Ferroelectric transition and the low-temperature dielectric relaxations were investigated in Sr4(La1−xSmx)2Ti4Nb6O30 ceramics. The dielectric nature of the present ceramics was governed by the radius difference between A1- and A2-site ions. Low-temperature dielectric relaxations were indicated for all the compositions…
Considering the structural unit of the rhombohedral BaTiO3 phase in the form of Ti(-O...Ti)6 which was constructed by neutron diffraction data, we revealed an atomic group in the form of a pyramidal complex anion TiO 3 2− . Inspection of the Raman spectra of this phase showed symmetry group C s for this complex anion.…
Abstract Treatment of Ti 3 AlC 2 powders in HF (2 h) results in exfoliation and formation of two‐dimensional Ti 3 C 2 layers with OH and/or F surface groups and conical scrolls.
A miniaturized complementary triangular split ring resonator (CTSRR) is proposed to provide a peak rejection of −35dB in the transmission characteristics. An equivalent circuit is generated to accurately predict the resonant frequency of the resonator. Miniaturization is achieved by optimizing the spacing between the…
Functional clothing are actually engineered textiles as they require to meet the stringent performance characteristics rather than the aesthetic properties. Therefore, the trial and error approach of product design does not seem to be a viable way for functional clothing. It needs more potent approaches of modelling,…
Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over…
Deuterium (D)-retention and -release behaviour from bulk solid tungsten (W) samples exposed to the outer divertor of ASDEX Upgrade were investigated. In the present plasma loading condition, no remarkable blister formation and no severe cracking/melting were observed on the W sample. D retained at the surface (up to ∼…
The present study was undertaken to evaluate ectopic new bone formation effects of apatite-coated silk fibroin scaffolds (mSS) seeded with adenovirus-mediated bone morphogenic protein-2 gene (AdBMP-2) transduced canine bone marrow stromal cells (bMSCs) in nude mice. In this study, bMSCs derived from canine were cultur…
The use of carbon nanotubes (CNT) for the application in in-plane strain detection is promising. In recent years, in-plane strain sensors constructed from CNT networks have been developed; however, few studied optimization of these sensors. In this paper, a study of the optimization of pure CNT networks in terms of pi…
Different equivalent circuit models were used to fit the impedance spectra of a novel polyaniline base (EB)/n-type Si heterojunction solar cell at different bias voltages. The photovoltaic cell characteristics, i.e., open circuit voltage (V OC), short circuit current density (J SC), fill factor (FF) and energy convers…
Presently, there is an ever growing need to develop reliable and eco friendly processes in nanotechnology research. The present study deals with the synthesis of silver nanoparticles (AgNPs) using Carthamus tinctorius flowers extract at 50oC and at room temperature. The synthesized nanoparticles were characterized usi…
[MoBr2(CO)3(L)2] complexes were synthesized with L = nicH (pyridine-3-carboxylate), picH (pyridine-2- carboxylate) and pydcH2 (pyridine – 2,6 – dicarboxylic acid). New lamellar materials intercalated with molybdenum(II) complexes were prepared by first calcinating the starting lamellar material at 823 K for four hours…
Ferromagnetic Ni 2 MnGa nanoparticles were prepared by post milling and annealing method. Differential scanning calorimetry studies confirm absence of martensitic and Curie transformation in the disordered state. It was found that the bulk alloy was annealed into a well-defined 7 M structure at around 1073 K. The resi…
To prepare high‐performance ferroelectric thin films on Si substrates for pyroelectric arrays applications, 0.74Pb(Mg 1/3 Nb 2/3 )O 3 –0.26PbTiO 3 ( PMN–PT ) thin films, with composition beyond morphotropic phase boundary, were deposited by radio‐frequency magnetron sputtering. Conductive perovskite La 0.6 Sr 0.4 CoO…
The goal of this research was to investigate the potential of newly synthesized gold complex trichloro(2,4,6-trimethylpyridine)Au(III) as an anticancer agent. The gold(III) complex was synthesized and grafted on nanoporous silica, MCM-41, to produce AuCl(3)@PF-MCM- 41 (AuCl(3) grafted on pyridine-functionalized MCM-41…
Infection is one of the common clinical problems that cause high rates of death in various surgical operations. Coating the surgical instruments or implants with antibacterial properties is a useful method to reduce such infections during the operation period. The high incidence of infections caused by the use of impl…
