Several magnetoelectric devices with different structures were prepared using Mn-Zn-ferrite/PZT composite. Its magnetoelectric effect, which arose from piezoelectric effects driven by magnetic force between ferromagnets, has been studied. Experiments showed that the magnetoelectric effects in these devices are much st…
Abstract With the aim of expanding their applications, particularly when joining metals, a simple but effective method is reported whereby the surface chemical reactivity of SiO 2f /SiO 2 (SiO 2f /SiO 2 stands for silica fibre reinforced silica based composite materials and f is short for fibre) composites with vertic…
Cu 2 O thin films were prepared on a Cu substrate with a room-temperature water bath in which a HF and HNO 3 mixture was used as the soak solution and dilute nitric acid was used as the deposit liquid. The influences of the preparation conditions, such as the molar ratio of HNO 3 :HF, the reaction temperature and the…
A preceramic polymer, is mixed with TiH 2 particles in different amounts and a MAX phase (Ti 3 SiC 2 ) are produced by heating in inert atmosphere. Composites produced by mixing the reactive mixture with an excess of TiH 2 powder, lead to Ti/Ti 3 SiC 2 /TiC bulk composites possessing greatly increased wear resistance…
Carbon nanotubes (CNTs) have attracted tremendous research interest area as promising sorbent material due to the large surface area for adsorption, excellent mechanical and chemical properties. To practically employ CNTs as a potential commercial sorbent, it is essential to form loosely packed architecture of CNTs in…
The structural properties of pyrochlore Eu2Zr2O7 under high pressure have been studied by using Raman spectroscopy and in situ angle-dispersive X-ray diffraction (ADXRD). The results of Raman spectra indicate that Eu2Zr2O7 undergoes a reversible structural change around 21.2 GPa. The results of Rietveld refinements fr…
The amount of nanoparticles released from industrial and consumer products has increased rapidly in the last decade. These products may enter landfills directly or indirectly after the end of their useful life. In order to determine the impact of TiO 2 and Ag nanoparticles on aerobic landfilling processes, municipal s…
We investigate the defect structures forming around two nanoparticles in a Gay–Berne nematic liquid crystal using molecular simulations. For small separations, disclinations entangle both particles forming the figure of eight, the figure of omega and the figure of theta. These defect structures are similar in shape an…
Abstract We investigate the low-temperature formation of MoS 2 films by radio frequency (RF) sputtering. This work is focused on reducing the number of sulfur defects and the improving electrical characteristics of sputtered MoS 2 films by low-temperature annealing in various atmospheres. 10 nm MoS 2 films were synthe…
Abstract CaFe 2 O 4 (CFO) nanoparticles with the orthorhombic phase were synthesized using solid state reaction (SSR), polymer complex (PC), microwave sintering (μW) and self‐propagating combustion (SPC) methods. Hydrogen (H 2 ) evolution by photocatalytic water splitting (WS), over these nanoparticles have been inves…
Abstract Described herein is a new nanocatalyst system that efficiently works in the aerobic oxidation of veratryl alcohol (VA), which is formed by cleavage of β‐O‐4 linkages in lignin, to veratraldehyde (VAL) under mild reaction conditions. The new nanocatalyst system comprised of ruthenium(0) nanoparticles supported…
Although the contact electrification of insulating polymers has been widely used in various technologies, the mechanism of electrification is still not well understood and several models have been proposed to explain the mechanism. Some of the models assume the existence of bandgap states that can store or release ele…
ABSTRACT A novel braid‐reinforced (BR) poly(vinyl chloride) (PVC) hollow fiber membrane was fabricated via dry‐wet spinning process. The mixtures of PVC polymer solutions were uniformly coated on the tubular braid which contained polyester (PET) and polyacrylonitrile (PAN) fibers. The influences of braid composition o…
Abstract Zinc(II), copper(II) and cobalt(II) metallated porphyrins/phthalocyanines and bis (4‐pyridyl) pyrrolidinofullerene ( 9 ) were used in a supramolecular approach for the sensitization of titania. Spectral properties of the chromophores were examined in the solid state showing strong absorptions at 700 and 800 n…
The ultrahigh-vacuum (UHV) coupling performance of NiTiNb shape memory alloy (SMA) rings was investigated by finite element (FE) simulations and experimental measurements. The contact pressure at the interface between the SMA ring and the vacuum pipe was measured and good agreements with the FE results were obtained.…
ABSTRACT The processing and properties of layered double hydroxides (LDHs)‐containing polypropylene (PP) composites have been studied extensively. However, no detailed studies have reported on how stearic acid (SA)‐intercalated and SA‐coated LDHs influence the properties of melt‐processed PP/LDH composites. Here, four…
The bending responses of functionally graded (FG) nanobeams with simply supported edges are investigated based on Timoshenko beam theory in this article. The Gurtin–Murdoch surface elasticity theory is adopted to analyze the influences of surface stress on bending response of FG nanobeam. The material properties are a…
Intrinsic thermal resistivity critically depends on features of phonon dispersions dictated by harmonic interatomic forces and masses. Here we present the effects of functional group mass variance on vibrational properties and thermal conductivity ($\ensuremath{\kappa}$) of functionalized graphene from first-principle…
Ba-doped CdO (CdO:Ba) thin films with different concentrations of Ba (0, 1, 2 and 3 wt.%) were prepared on glass substrates by spray technique using perfume atomiser. The effect of Ba doping concentration on the structural, morphological, optical, photoluminescence and magnetic properties of the CdO films was investig…
A series of manganese-cerium oxide (MnOx-CeO2) catalysts supported by Ti-bearing blast furnace slag were prepared by wet impregnation and used for low-temperature selective catalytic reduction (SCR) of NO with NH3. The slag-based catalyst exhibited high nitrogen oxide removal (deNOx) activity and wide effective temper…
