In the title compound, C22H16Br2O2, which has approximate non-crystallographic inversion symmetry, the dihedral angles between the central ring and the pendant rings are 89.1 (4) and 82.4 (3)°; the dihedral angle between the pendant rings is 12.1 (4)°. In the crystal, the packing is influenced by van der Waals forces…
Rare earth ion-doped nanoparticles NaYF4:Yb3+,Ho3+ is one of the most efficient up-conversion nanosystems, when mixing a TiO2 heterogeneous layer outside can extends the range of NaYF4:Yb3+,Ho3+ nanoparticles absorb solar energy. In this work, a multi-functional mixed NaYF4:Yb3+,Ho3+-TiO2 structure was synthesized. Th…
In 6 mol/L HCl medium, NaH2PO2 reduced HAuCl4 to generate gold nanoparticles (AuNPs). AuNPs have a strong resonance Rayleigh scattering (RRS) peak at 369 nm. As HAuCl4 concentration increases in 0.04-0.8 mmol/L, the AuNPs generated increase, and the RRS peak ΔI369nm enhanced linearly, the linear regression equation wa…
A supporting body of diatomite-based porous ceramics was prepared by a solid-phase sintering process and low-temperature calcination process. nanoTiO2 membrane was loaded on the carrier by the hydrolysis precipitation method and using TiCl4 as the precursor. The influences of various parameters such as the initial con…
This paper focus on the mass transportation in integrited μDMFC stack. The situation that simply increasing the integrity of stack will deteriorate the performance of single cell, was confirmed by implementing and testing a highly-integrated μDMFC power supply system. Based on works above, a centrual-inlet μDMFC stack…
The compound trans-[PtCl2(NH2C6H4CO2H)2] has been prepared from the hydrolysis of a platinum diimine complex, and has been characterised by X-ray crystallography. The crystal structure revealed that the compound forms a two-dimensional hydrogen-bonded network in the solid state, with pairs of O–H···O hydrogen bonds be…
The demand for ever more functions and higher processing speed in mobile devices has raised the energy consumption of such devices beyond the capability of low-energy-density and long-charging-hour lithium batteries. As an energy source, fuel cells are much better than lithium batteries due to their higher energy dens…
Putting forward a kind of flexible electroplating method based on the fission type vertical plating bath, A new type of gravitation electro-galvanizing testing apparatus was developed. This paper expatiate the design thought of the testing apparatus, and introduces the design principle and constituent as well as the t…
As an attempt to contribute to the understanding of the corrosion processes of anti-sulfur steel in CO2 and H2S containing environment with different species, the corrosion behavior of SM 80SS tubing steel immersed in CO2 and H2S containing solution was analyzed in this work. To determine the corrosion behavior of SM8…
In the present research, silver antimony co-doped tin dioxide electrodes were prepared via dip-coating pyrolysis method.

The nano-Ni was got under a constant current , voltage , barometric pressure, hydrogen and argon gas . The nickel nanopowders were tested through the Scan Electron Microscope (SEM ), X-ray diffraction…
Chose high-chromium cast iron as the material to make the mud pump shell, the composition of high-chromium alloy has been optimized and five kinds of alloy ( A, B, C, D and E) are designed. Furthermore, using the heat treatment method of air-cooled quenching of 1040°C + 260°C tempering, the relationship among material…
This study preliminarily evaluated water absorbency and potassium release property of a novel hybrid hydrogel material as a potential hydrogel K-fertilizer. This hybrid hydrogel material was prepared by introducing activated K-feldspar powder into starch-graft-PAA hydrogel networks via aqueous solution polymerization.…
Radioactive wastewater on accident cases is characterized by large quantity and complex quality, so the treatment process must be able to meet the request of large quantity, low energy consumption and mobile processing. The quantity and quality of radioactive wastewater under core melt accident case was estimated. The…
According to a new version of equations of elasodynamics of quasicrystals suggested by Ref, a finite difference method of the anti-plane elastic dynamic equations of 1D hexagonal and 3D icosahedral quasicrystals is developed. Further the dynamic behaviour of the material with a model III crack under impact loading is…
A correct composition of two kind of magnetic anisotropy of ellipsoidal nanoparticles: crystalline anisotropy and shape anisotropy - has been carried out. It was shown that according to the shape anisotropy the effective anisotropy constant can change non-monotonically. The temperature dependence of effective anisotro…
