Fe3O4/poly(St-co-MPS) particles were prepared by encapsulation of Fe3O4 nanoparticles into copolymers of styrene (St) and 3-trimethoxysilylpropylmethacrylate (MPS) (poly(St-co-MPS)) prepared by miniemulsion copolymerization. It is found that the structure of the Fe3O4/poly(St-co-MPS)/SiO2 composite particles prepared…
We use resonance Raman scattering (incident photon energies between 1.8 and 4.13 eV), $\text{LDA}+\text{U}$ calculations, spectroscopic ellipsometry, and oblique IR reflectivity to characterize the strong electron-phonon interactions in the disordered perovskite ${\text{LaFe}}_{0.5}{\text{Cr}}_{0.5}{\text{O}}_{3}$. Wh…
We investigate the ballistic thermal conductance of electrons in gated graphene ribbons with width above 20 nm and clarify both the temperature and the Fermi-level dependences. In the intrinsic graphene ribbons, the normalized thermal conductance by the quantum conductance, ${\ensuremath{\kappa}}_{0}$, increases monot…
The 0 K onsets (E(0)) of a series of trichlorosilane derivatives SiCl(3)R --> SiCl(3)(+)+ R(*) (R = Cl, H, CH(3), C(2)H(5), C(2)H(3), CH(2)Cl, SiCl(3)) are measured by threshold photoelectron-photoion coincidence spectroscopy. The well-known heat of formation of SiCl(4) is used as an anchor to determine the heat of fo…
Microstructural evolution of ZK60 magnesium alloys, during twin roll cast (TRC) and hot compression (HC) with a strain rate of 0.1 s−1 at 350 °C and subsequent annealing at temperatures of 250–400 °C for 102−5 × 105 s, has been observed by optical microscopy (OM), transmission electron microscopy (TEM) and electron ba…
We report the realization of superconductivity by $5d$ element Ir doping in LaFeAsO, a prototype parent compound of high-temperature iron-based superconductors. X-ray diffraction patterns indicate that the material has formed the ZrCuSiAs-type structure with a space group $P4/\text{nmm}$. The systematic evolution of t…
Food processing surfaces fouled with organic material pose problems ranging from aesthetic appearance, equipment malfunction and product contamination. Despite the importance of organic soiling for subsequent product quality, little is known about the interaction between surfaces and organic soil components. A range o…
Hybrid catalysts have been prepared by the immobilization of a Rh complex on carbon nanotubes and nanofibres. To tether the complex, a siloxane type bond has been created by reaction of a trimetoxisilane end of a ligand and -OH phenol type groups on the supports surface. The hybrid catalysts have been tested in the hy…
Abstract The effect of corrosion on the tensile behavior of an as‐cast AZ91 alloy was investigated via systematical experiments. The corrosion residual strength of the AZ91 magnesium alloy is approximately negative linear dependent on the extreme depth of corrosion pit, which was quantitatively obtained by the corrosi…
YbPO 4:Er nanocrystals with upconversion fluorescence were successfully prepared using a two-step process, i.e., gelatin gel growth of YbPO 4:Er· n H 2 O precursors and subsequent annealing. The YbPO 4:Er· n H 2 O precursors grown in gelatin gels were milky white, spherical in shape and uniform in size and appearance.…
Abstract Phase structure of composite polypropylene (PP)/ethylene–propylene–rubber (EPR)/coated nano‐CaCO 3 composites, used in the manufacture of bumpers, with and without compatibilizers has been investigated using scanning electron microscopy (SEM), dynamic mechanical analysis (DMA) mechanical tests, and differenti…
In this work, Carboxymethylcellulose/single walled carbon nanotube hybrids are prepared. Our goal is to use the non-covalent association of an anionic polysaccharide and single walled carbon nanotubes to prepare a biocompatible complex which preserves the intrinsic properties of the nanotubes. The hybrids are characte…
The effect of chirality on the liquid crystal organization has been systematically investigated between (S,S)- and (R,R)-isomers of a dichiral azobenzene compound. The racemic mixture was found to show the cubic phase (Im3m), indicating that the studied compound shows the cubic structure without the effect of chiralit…
Multifunctional nano-micelles formed by amphiphilic gold-polycaprolactone-methoxy poly(ethylene glycol) (Au-PCL-MPEG) nanoparticles were synthesized and evaluated for potential drug delivery applications. Amphiphilic Au-PCL-MPEG nanoparticles were synthesized by the ring-opening polymerization of epsilon-caprolactone…
Abstract Effects of filler size and content on the shrinkage of injection molded poly(butylene terephthalate)/poly(ethylene terephthalate)/talc (PBT/PET/talc) composites were investigated. Circular plate specimens were examined by a field emission scanning electron microscope and a numerical analysis code was used for…
Energy and exergy assessments are reported of integrated power generation using solid oxide fuel cells (SOFCs) with internal reforming and a gas turbine cycle. The gas turbine inlet temperature is fixed at 1573 K and the high-temperature turbine exhaust heats the natural gas and air inputs, and generates pressurized s…
Epoxy nanocomposites were fabricated using two kinds of nanofiller, amino-functionalized multi-walled carbon nanotubes (CNTs) and non-treated long carbon nanofibers (CNFs). The non-cured mixtures were analysed through viscosity measurements. The effect of the nanoreinforcement on the curing process was determined by d…
High-density horizontally aligned single-walled carbon nanotubes (SWCNTs) have been grown by annealing Fe catalyst in air and optimizing catalyst thickness in the gas flow process. The aligned SWCNT density reaches >60 nanotubes per 100 microm and the length can be a few millimeters. Interestingly, the growth of align…

By combining the results of both x-ray diffraction and neutron total-scattering experiments, we show that $\text{Ni}{(\text{CN})}_{2}$ exhibits long-range structural order only in two dimensions, with no true periodicity perpendicular to its gridlike layers. Reverse Monte Carlo analysis gives an experimental distincti…
