Magnetoelectric (ME) materials have attracted continuous attention due to their potential applications in the fields of sensors, actuators, and transducers. A large ME coupling originated from a clamping structure was reported. ME coefficient of 0.95V cm1Oe1was obtained without amplifier at the planar acoustic frequen…
Atomistic modeling based on the density functional theory combined with the quasi-harmonic approximation is used to investigate the lattice parameters and elastic moduli of the P6̄ and P6̄′ phases of Si3N4. β-Si3N4 is set as a benchmark system since accurate experiments are available. The calculated lattice constants…
Currently, there is little experience about design of the 1-tower-double-circuit DC transmission lines. But the electromagnetic field distribution under its lines is complicated. In order to study the nominal electric field distribution of 1-tower-double-circuit DC transmission lines under different situations and a v…
The excited state intramolecular proton transfer (ESIPT) coupled charge transfer of baicalein has been investigated using steady-state spectroscopic experiment and quantum chemistry calculations. The absence of the absorption peak from S1 excited state both in the experimental and calculated absorption spectra indicat…
The uniaxial tensile tests are generally used to measure the yield stress and/or tensile stresses. The majority of the results, resulting from this method and deferred in the literature on the mechanical properties of amorphous materials, were obtained in the ribbons form generally produced by melt spinning. This limi…
The weldability of the steel can be improved by formation of intra-granular ferrite (IGF) in heat affected zones (HAZs) on the edge of weld bead. The nucleation mechanism of IGF of Ti-killed high strength low alloyed (HSLA) steel has already been investigated with the aid of transmission electron microscope. Titanium…
The influence of mechanical stress on the magnetic states of multiaxial heterophase magnetic materials is investigated using a model of two-phase nanoparticles. The range of critical fields for the reversal of the magnetic moments of phases is calculated and phase diagrams are built to assess the effect of interface e…
The flow stress behavior of the 7075-T6 aluminum alloy was studied through single-pass compression experiment by using MMS-300 simulator within temperature range of 300-450°C and strain rate range of 0.01-40s-1. Then a simulation of compression was carried out and the influence of deformation velocity on load and defo…
Polyimide (PI) has good mechanical properties, heat resistance and low temperature performance, and thus shares a wide range of applications. Atmospheric pressure plasma jet was designed for polyimide films surface modification in this paper. The impacts of exposure time and gas ratio on the film surface morphology an…
The finished and preformed forgings of the rear lower arm are shown respectively, the shape of the rear lower arm is very complex.The tops of three branch arms are thick lumps and its central part consits of quite thin ribs.This forging is much more slender than the ordinary weldment made of steel plate and its weight…
Short-cut grass and starch were selected as raw materials to prepare environmentally friendly composite by hot-pressing method. Results indicated that short-cut grass and starch were easily mixed uniformly by water medium and adapt to hot-pressing process. Hot-pressing time and hot-pressing temperature influenced the…
A Ce-Zr-Ti oxide catalyst was prepared by an impregnation method and tested for the selective catalytic reduction of NO with NH3. The Ce-Zr-Ti oxide catalyst exhibited high activity and more than 95% NO conversion was obtained within the temperature range 300-500 °C at the high gas hourly space velocity of 50,000 h-1.…
The effect of carbon ion species distribution in arc discharge process becomes significant for the formation of carbon nanomaterial. It is essential to account for the velocity distribution of each carbon ion species to determine the greatest contribution from the kinetic energy possesses by each species that govern t…
This special Energy Materials issue of Materials Research Innovations includes four selected papers from those presented at the 2013 PVSAT Conference held in Swansea on 10–12 April. PVSAT is an ann...
Capping CdS nanorods on one side with Au nanoparticles makes these asymmetric nano-objects amphiphilic. As D. Mandler and co-workers report in article 1300030, this enables the formation of 2D nanometric monolayers at the liquid/air interface using the LB technique. This interesting system is studied in situ by variou…
Nanometer-sized gold particles supported on Cerium Oxide (CeO2) were prepared by the method of deposition-precipitation. These catalysts exhibited good activity for the combustion of formaldehyde and the factors affected the activity of the catalyst were observed. The results showed that CeO2 powder prepared by Ce (NO…

Differentiation in microstructural characteristics ofPunica granatumfruit in response to different dynamic temperatures (2 oC, 4 oC, 6 oC, and 8 oC) during cold storage inside the fibre insulation materials was investigated. The results from Fourier Transform Infrared Spectroscopy (FTIR) measurements showed that the p…
All future engine developments must consider the primary task of achieving the required emission levels. An important step towards the development of combustion engines is the optimization of the flow in the intake ports. The charging movement in the combustion chamber, which is generated by the intake flow, considera…
Today various nano-moieties including nanoparticles, nanocubes, nanosticks, nanoflowers and nanoprimes have been synthesised. It is an interesting challenge to build nanostructures using those nano-moieties as blocks owing to their distinct properties and numerous applications. Herein, we demonstrate a smart way, self…
