The true breaking stresses and the ultimate tensile strengths of 11 metals with various structures are calculated. Moreover, the fracture strengths of these metals at 0 and 298 K are calculated in the amorphous (σf, a) and nanocrystalline (σ ,nano max ) states formed upon severe plastic deformation. The temperature de…
Well-defined amphiphilic diblock copolymers (PAMPS-b-PG2) composed of a hydrophilic linear polyelectrolyte and hydrophobic blocks bearing pendent dendritic moieties was synthesized via reversible addition–fragmentation chain transfer (RAFT) controlled radical polymerization of 3,5-bis[3′,5′-bis(benzyloxy)benzyloxy]ben…
Biomolecule-directed growth and assembly of nanomaterials utilizes highly specific interactions to provide the exciting prospect of producing a new generation of precisely arranged, stimuli responsive, and reconfigurable nanoarrayed structures for a wide range of applications from catalysis to energy storage. With an…
The optical properties of thin films of barium strontium titanate (BST) are important due to its wide band gap, high refractive index and low absorption coefficient and hence find application in electro-optic and non-linear optical devices. Ba 0.7 Sr 0.3 TiO 3 (BST) thin films were deposited by RF magnetron sputtering…
The dyeability of PLA fabric with the natural emodin dye has been investigated. The effect of different factors, which are dyeing temperature, dyeing time, dye bath pH value, bath ratio, dye concentration and mordants, has been studied. The color of each dyed sample was evaluated in terms of the K/S value, and the col…
Carbon dioxide reforming of methane to synthesis gas over an alumina-supported 1% Ni-based catalyst has been investigated at atmospheric pressure. The reforming reactions were carried out at reaction temperatures of 500–800°C. The catalyst activity and stability, carbon deposition, and synthesis gas H2/CO ratio were d…
The sea cucumber Holothuria forskåli possesses a specialized system called Cuvierian tubules. During mechanical stimulation white filaments (tubules) are expelled and become sticky upon contact with any object. We isolated a protein with adhesive properties from protein extracts of Cuvierian tubules from H. forskåli.…
We have investigated plasma–surface interactions by performing molecular dynamics (MD) simulations. However, such simulations have a high computation cost and are limited to simulations of materials of nanometer order. In order to overcome this limitation, a complementary model based on the binary collision approximat…
Electrical switching studies on amorphous Ge17Te83−xSnx thin films (1≤x≤4) has been done to find their suitability for Phase Change Memory application; Bulk ingots in glassy form are prepared using conventional melt quenching technique and the thin films are coated using flash evaporation technique. Samples are found…
ZnO thin films were prepared on c-plane sapphire (Al2O3) substrates using pulsed laser deposition at different substrate temperatures (200, 300 and 400 °C). The effects of substrate temperature on the structural and stoichiometry properties of ZnO films have been investigated by X-ray diffraction (XRD), X-ray photoele…
The oxidation state and distribution of Fe in olivine in a lherzolite xenolith from the Oku district, Oki-Dogo Islands, Japan, were investigated. A lherzolite xenolith collected from a volcanic neck of alkali olivine basalt contains olivine, orthopyroxene, clinopyroxene, and a small amount of spinel. Anhedral anorthit…
Nolanite Fe(2.5)V(1.5)V(5.6)O(16) nanocrystals have been successfully achieved by a facile solvothermal method for the first time. The magnetic semiconducting and semiconductor-insulator transition characters of the synthetic nolanite sample render it a promising candidate for the design of data storage devices and te…
The critical detonation diameter of industrial explosive charges is analyzed as a function of their state characteristics (composition, density, and structure) and the presence of a casing. The main reason for the increase in the critical diameter with increasing density of ammonium nitrate explosive charges is the re…
Functional polymer nanograss and nanotubes with active epoxy groups were synthesized by a surface-initiated photopolymerization pattern transfer method in cylindrical alumina nanopores. The nanograss structures were obtained when the neat glycidyl methacrylate (GMA) monomer or the mixture of GMA monomer and ethylene g…
This work deals with a problem of calculation of micro stress and micro deformation in matrix composites with random inclusions over the volume. A stochastic structure of composites is described by a set of multipoint moment functions that are used for searching the statistical characteristics of deformation fields. T…
In this study, 0.75BiFeO3–0.25BaTiO3 ceramics doped with Mn and Cu (1, 2, 3, 4 and 5 mol%) have been fabricated with an effective solid-state reaction method developed for high purity ceramics. Attention has been focused on relationships between sintering conditions, phase formation, density, and magnetoelectric prope…
With a new concept of reducing the spinel particles in ZnO varistor ceramics (ZVC), the molar ratio of Sb2O3 (MS)/Bi2O3 (MB) and the effect of the sintering temperature (TS) on densification behavior and varistor voltage (Vb: V1mA/mm) were investigated. The densification behavior of ZVC during the sintering process wa…
Alloys 600 and 182 are used as structural materials in pressurized water reactors (PWRs) and have been found to undergo stress corrosion cracking (SCC). Alloys 690 and 152 are the replacement materials of choice for Alloys 600 and 182, respectively. The objective of this work is to determine the crack growth rates (CG…
The solutions of the exact boundary value problems for the order parameter and susceptibility were obtained numerically for the incommensurate thin films with the one-component order parameter. The spatial variations of the order parameter and susceptibility and their temperature dependences were calculated for some p…
Oriented PbTiO3 ceramics were obtained by slip casting under a high magnetic field, and the orientation factor was 90%. Such highly oriented perovskite ceramics by slip casting under a high magnetic field have never been reported as far as we know. It was thought that dispersibility and crystallinity of the powder wer…
