In this work, the influence of hydrogen on magnetic properties of R2(Fe,M)17 (R = Ce, Lu, Y; M= Fe, Mn, Si, Cr, Ni) compounds is reported. Special attention is given to the compounds with Ce, because Ce ions might be in a mixed-valence state. Measurements of the temperature dependence of magnetization in weak magnetic…
In this article, a new process was used to make flame resistant polyacrylonitrile (PAN) fibers by surface modification. The effects of the treating conditions during the copper ion treatment, aqueous mixture of hydrazine hydrate treatment and high temperature treatment on the mechanical properties and flammability of…
A method has been developed for processing spectra of multiple small-angle neutron scattering (MSANS) to obtain information about substance heterogeneities, namely, their size and concentration. A method has been proposed for constructing the dependence of the MSANS line width on the sample thickness starting from the…
A study has been made of the evolution of the microstructures and textures in three kinds of low-carbon steel sheets (MAFE, BH and IF) having well developed <111>//ND texture that were rolled by low reductions and annealed at 780 °C in Ar atmosphere. The steel sheets developed different microstructures and textures, e…
Slide gates are installed at the bottom of a ladle or tundish to control the flow of molten steel. It plays an important role in ladle refining process and continuous casting. Al2O3-ZrO2-C refractories are widely used as slide gate materials due to its excellent corrosion and thermal shock resistance. At the start of…
The effect of the shape of filler particles on the mechanical properties of a composite material based on ultrahigh-molecular-weight polyethylene produced by thermal compacting after preliminary mechanical activation of the initial materials is studied. As a filler, Al 2 O 3 in the form of an ultradispersed powder wit…
Phosphate glasses containing fixed concentration of rare-earth with and without metallic nanoparticles (NPs) having compositions (59.5-x) P2O5-MgO-xAgCl-0.5Er2O3, where 0 ≤ x ≤ 1.5 mol% was prepared using melt-quenching technique. Spectral characterizations were made using UV-VIS-IR spectroscopy and photoluminescence…
This paper addresses use of coarse-grained mesoscale model to look at angle dependencies in an epoxy-copper (I) oxide interface in order to understand roughness effects on adhesion. The parameterization of the coarse-grained beads were previously parameterized from the molecular level [1–3] for the same polymer and co…
Silk sericin, a gumming protein from silk cocoons, has been a considerable natural protein-based biopolymer for fabrication of desired constructs for potential tissue engineering applications. This study investigated the formulation of a novel biopolymeric silk sericin/poly (vinyl alcohol) film with genipin as crossli…
Preparation of needle-like aragonite particles from calcium nitrate solution in batch and flow reactors Needle-like aragonite particles for application in paper industry were synthesised from calcium nitrate solution. Calcium nitrate was prepared from waste lime. Samples of precipitated aragonite were prepared both in…
The finite element ANSYS/LS-DYNA was applied to simulate the propagation characteristics of stress waves in laser shock processing (LSP) for DD6 single crystal alloy materials. The constitutive model of dynamic response and computational modeling of LSP was built in this paper. Results of numerical simulation indicate…
We report on the effect of different gaseous environments (air, argon and Ar/H2) on the structural and magnetic properties of Zn0.98Co0.02O synthesized by the solid state reaction route. We have also studied the effect of different annealing times and temperatures on the as synthesized samples. M-H curves of the air s…
Abstract Novel polyimide nanoparticles confining maximum 12.5 wt % of highly dispersed Au nanoparticles (size: 5.6 nm) were continuously fabricated by using a multistep microfluidic reaction system; the particles show good activity for the hydrogenation in scCO2 with excellent yields and selectivity without leaching a…
Oil palm frond pulp (OPF) was blended with activated carbon for the purpose of active packaging in this preliminary study. It was aimed to investigate the effect of in-situ activated carbon on physical and mechanical properties of the pulp handsheets made from OPF. Testing of property performances of the resulted hand…
Resistance to butanol is a key factor affecting microbial ability to produce economically profitable amounts of butanol. In this study, an Escherichia coli strain capable of growth in the presence of 1.5% butanol was isolated. The mutant MG1655 ButR was characterized by increased resistance to ethanol, isopropanol, an…
Crystal nucleation parameters have been determined in a wide range of compositions of photo-structured glasses of the lithium-silicate system (23.40–45.00 mol % Li 2 O) for homogeneous and heterogeneous nucleation. The homogeneous nucleation occurred in glasses without photosensitive additives and with photosensitive…
Cyclodextrin complexation and pH adjustments have been reported as useful tools to increase the solubility of drug. The aim of this study was to investigate the influence of both cyclodextrin and pH on the overall solubility of ketoprofen. β-cyclodextrin (β-CD) and hydroxypropyl β-cyclodextrin (HP-β-CD) were used for…
Biosynthesis of nanoparticles by plant extracts is currently under exploration. Biological methods are a good competent to chemical procedures, which are environmentally friendly and convenient. We report the use of new plant extract of Cuscuta reflexa in the extracellular biosynthesis of silver nanoparticles. Bioacti…
Micro-structured surfaces on brittle materials, e.g. ceramic and glass, are gaining increasing application in a range of areas. In this paper, fast tool servo (FTS) diamond turning has been applied to machine micro-structured surfaces on brittle materials and the machined surfaces has been observed to study its machin…
The Anadaragranosa and Pernaviridis shell sample were prepared in powder and plate form has been studied. The crystal structure of the shells was studied by x-ray diffraction (XRD). The identification and quantitative analysis were performed by the XRD patterns and the Rietveld method. It found that the crystal struct…
