A synthesising method is reported with an enhanced solid state reaction to fabricate SnO2 nanorods. The structure and morphology of the SnO2 nanorods were characterised by X-ray diffraction and transmission electron microscopy. The results showed that the nanorods were rutile SnO2 with a diameter of ∼30 nm and length…
The theory of the plasmon resonance excitation in the plasmonic-crystal structure on a dielectric substrate is presented. The effect of the plasmon resonance intensity oscillation as a function of the substrate thickness is predicted. It is shown that the enhancement of the plasmon resonance intensity occurs in a broa…
In this paper, the WC-16TiC-xTaC-10Co mixture mixed by WC 0.52μm, (W, Ti, Ta)C 2.9μm and Co1.36μm and prepared by high-energy ball milling, changed the VC and Cr3C2 adding amount. After ball milling for 60 hours, an average particle size of 220nm powder was prepared and it was cold isostatic pressed at 300MPa and vacu…
Abstract: With the purpose to improve the mechanical properties and cut costs of chitosan films, a series of gelatin-chitosan films were prepared. The effect of gelatin content on the mechanical properites of films was studied. FT-IR spectrum and X-ray diffraction analysis showed good compatibility between gelatin and…
The urethane reaction kinetics of 1,2-propanediol and 1,3-butanediol with phenyl isocyanate are investigated in toluene. In-situ FT-IR is used to monitor the reaction to work out rate constant. The urethane reaction has been found to be a second order reaction and is largely accelerated with triethylamine as catalyst.…

We fabricated and characterized the magnetoelectric (ME) properties of 3-0 ME composite materials comprised of the high piezoelectric voltage coefficient material, 0.9Pb(Zr0.52Ti0.48)O3-0.1 Pb(Zn1/3Nb2/3)O3 + 0.005Mn (PZT-PZN), and the magnetostrictive material, Ni0.8Zn0.2Fe2O4 (NZF). As the ME effect is generated by…
The size and shape dependence of the melting temperature of Boron Carbide (B4C) nanoparticles has been investigated with a numerical thermo dynamical approach. The problem considered in this paper is the inward melting of nanoparticles with spherical and cylindrical geometry. The cylindrical Boron Carbide (B4C) nanopa…
Bismuth sodium titanate (Bi0.5Na0.5TiO3 , abbreviated as BNT) nanoparticles were synthesized by hydrothermal process at various temperatures for 10 h. The results showed that all the as-prepared nanopowders are well crystallized and the crystallite size increased with the increase of hydrothermal temperatures under th…
Plasma-wall interaction in fusion devices is unavoidable and leads to material erosion, dust formation, and tritium retention. Erosion of plasma-facing material and generation of dust inside ITER can significantly affect the operation. This is because the total in-vessel dust and tritium inventories during an operatio…
The luminescence and Raman spectra of sol-gel-derived ZnO microcrystals with different iron and magnesium contents have been studied. It has been revealed that, in some cases, the doping material phases precipitated.
Abstract：Aluminum matrx composites reinforced by in situ ZrB2 particles are fabricated from A356-AlB-K2ZrF6 system via in-situ melt reaction method, and the morphologies, sizes and distributions of the in situ particles as well as the microstructures, mechanical mechanisms of the composites are investigated by XRD,SEM…
LVL (Laminated-Veneer Lumber) has many advantages and economic values, which is important for wooden boat construction. The recovery of veneer, the main material of LVL, is higher than sawn-timber and their drying process is faster. LVL produced with a continuous press has been approved as an engineered material with…
Nanostructured Al2O3-13wt.% TiO2 coatings were prepared by plasma spraying using agglomerated nanocrystalline powders via a spray drying method. The as-sprayed coatings and their worn surface were characterized using scanning electron microscope (SEM). The tribological characteristics were evaluated on block-on-ring c…
Hydrogen generation through high temperature solid oxide electrolysis cells (SOEC) has recently received increasingly international interest in the large-scale, highly efficient nuclear hydrogen production field. To achieve cost competitive electrolysis cells that are both high performing i.e. minimum internal resista…
In this study a series of polyimide (PI) films were synthesized from fluorinated and nonfluorinated monomers which contained diamines and dianhydrides. The influence of fluorine-containing groups on the glass transition temperature (T g) and tribological properties of the PI films was investigated. The wear mechanism…
A novel cheap macromolecular intumescent flame retardants (Zn-MIFR), was synthesized, and its structure was a caged bicyclic macromolecule containing phosphorus-silicon characterized by IR. Epoxy resins (EP) were modified with Zn-MIFR to get the flame retardant EP, whose flammability and burning behavior were characte…
Open resonators have been widely applied in dielectric sensing and laser cavity. In this letter, we designed and fabricated a novel open resonator using a metamaterial transmission line medium. The open-resonance effect which is generated by multiple negative reflections is demonstrated experimentally. It may open up…
The directional solidification of ternary systems at a constant rate is studied. The following analytical solutions to the problem are found: the temperature and concentration distributions and the fractions of the solid phases of solidifying components in the parent and cotectic mushy zones, which represent a phase t…
Non-magnetic steels are required in energy and transportation fields such as superconducting energy storage equipment, magnetic liquid power generation equipment, superconducting generators, superconducting power transmission and ship electromagnetic propulsion. Experimental research on steel making, hot rolling, solu…
