Combustion synthesis of Ti3SiC2 was carried out in air with Si3N4, SiC, and Si as Si sources respectively, and the effect of Si source on the phase composition of the products was investigated. With Si3N4 as Si source, the major product was TiCxN1−x and no Ti3SiC2 was synthesised. When SiC and Si were used, Ti3SiC2 wa…
This study focuses on preparation of mulberry-like CaCO3/SiO2 composite particles with a mechanochemical method and their application in superhydrophobic films. Silicon dioxide nanoparticles were adhered to calcium carbonate microparticles to form mulberry-like composite particles through vigorous stirring, which prev…
Eu 2+ doped BaAl 2 Si 2 O 8 phosphor was synthesized by one-step calcination of precursors that were prepared by chemical co-precipitation. The thermal degradation properties of BaAl 2 Si 2 O 8 :Eu 2+ were investigated by photoluminescence, lifetime and chromaticity coordinate measurements. BaAl 2 Si 2 O 8 :Eu 2+ is e…
A nanoscale thermodynamic approach is developed to quantify the multiphase equilibrium in nanocrystalline alloy systems. The nanoscale multiphase equilibrium calculations indicate that the activities and mole numbers of phases in alloy systems change diversely as a function of the nanograin size at constant temperatur…
Rare earth stabilised tetragonal zirconia polycrystals (TZPs) with stabilisers other than yttria and ceria are scarcely examined as structural ceramics. Unstabilised pyrogenic zirconia nanopowder was coated with 2·25 mol.-% of ytterbium oxide via the nitrate route. Yb-TZP ceramics were consolidated by hot pressing in…
In the present paper, we describe a new and original method to obtain transparent, siloxane-based composites, with high refractive index (up to 1.68). The method is based on the decomposition of Zn-siloxane, mixed with a poly-(dimethyl)-block-(phenyl)siloxane matrix in different ratios. It was found that after treatme…
In this work, the electrochemical deposition of copper on aligned multi-walled carbon nanotubes (MWCNTs) from an aqueous electrolyte is described. The addition of sodium dodecyl sulphate has been applied to enhance wettability of the hydrophobic MWCNT surface. The transfer of the MWCNT–copper composite film from nicke…
This paper introduces an in-plane uniaxial anisotropy control method of Fe72Si14B14 magnetostrictive thin-film for high sensitivity of MI sensor. The anisotropy can be controlled by inverse-magnetostriction and inducing a bias stress using the difference of thermal expansion coefficient in bimetal structure. We can co…
Based on the Parlinsk–Li–Kawasoe method and density function theory, the phonon properties of some phase change memory materials are calculated. Thermal conductivities are acquired from our calculation, and they are in reasonable agreement with our experimental measurements. Phonon dispersion curve, mismatch between p…
Cs x WO 3 nanoparticles in the range of 20–50 nm have been successfully synthesized by the supercritical solvothermal approach, where after dissolving WCl 6 and CsOH in a mixed solution of water, ethanol and oleic acid, the solution was heated at 300°C. The products were characterized by X-ray diffraction, TEM, HR-TEM…
Polycrystalline ceramic samples of magnesia doped GdSm1–xMgxZr2O7–x/2 have been prepared by conventional solid state reaction method using high purity oxides. The influence of magnesia dopant content on densification, microstructure and electrical properties of GdSm1–xMgxZr2O7–x/2 ceramics are investigated. Magnesia d…

Nanoconfined water and surface-structured water impacts a broad range of fields. For water confined between hydrophilic surfaces, measurements and simulations have shown conflicting results ranging from "liquidlike" to "solidlike" behavior, from bulklike water viscosity to viscosity orders of magnitude higher. Here, w…
High purity Ti3AlC2 samples were prepared by an infiltration sintering method. The current carrying friction and wear characteristics of high pure bulk Ti3AlC2 dry sliding against a GCr15 bearing steel disc were experimentally investigated on a pin-on-disk type tester at several sliding speeds from 20 to 60 m s−1, dif…
Thin films of titania (TiO2) doped with 1–5 wt-%Fe were spin coated on glass slides and then annealed at 500°C for 2 h. Results revealed that all of the films were ∼500 nm in thickness and consisted of anatase. Increasing the dopant levels revealed the following trends: the major (101) anatase peak shifted to larger l…
Structure-activity relationship (SAR) studies are essential in the generation of peptides with enhanced activity and efficacy as therapeutic agents. In this study, we report a Structure-activity relationship study for a family of mimetic peptides derived from type IV collagen with potent anti-angiogenic properties. Th…
