AbstractAbstract
[en] The preparation methods of Cr2O3 hollow micro/nano-sphere are summarized. The preparation methods are mainly divided into hard template method, soft template method and template-free method. The advantages and disadvantages of different methods are introduced and discussed. At the same time, the preparation methods of Cr2O3 hollow micro/nano-spheres are prospected (paper)

AbstractAbstract
[en] The influence of spatial and chromatic aberrations on the parameters of the 730 MeV beam extracted from a SALO recirculator is studied using numerical simulation. The influence of fringing fields and the heterogeneity of the guide field of dipole magnets on the beam parameters at the extraction point is studied for different orders and types of aberrations. Estimates of the contributions of the different types of aberrations to the extracted beam emittance are presented.

AbstractAbstract
[en] To solve the problem that scene details and visual effects are difficult to be optimized in high dynamic image synthesis, we proposes a multi exposure image fusion algorithm for processing low dynamic range images in YCbCr space, and weighted blending of luminance and chromatic aberration components respectively. The experimental results show that the method can retain color effect of the fused image while balancing details of the bright and dark regions of the high dynamic image. (paper)

AbstractAbstract
[en] Highlights: • Solubility limits of chromium in silicate melts are given for a wide fO2 range. • Diffusivity of multivalent chromium were determined by square wave voltammetry. • Basicity and viscosity of the silicates affects the corrosion behavior of NiCr alloy. • Dissolution of Cr2O3 is kinetically limited by the diffusion of Cr in silicates.

AbstractAbstract
[en] An absorption spectrometry coupled with flow injection analysis has been developed and tested for the analysis of the Cr2O72-/MnO4- mixtures. Even though one has to inject the sample twice into the FIA system and the process of the sample treatment is required to completely destroy the MnO4- ion for the analysis of the Cr2O72- ion, the new method has definite advantages over the current method. It utilizes only a single analytical wavelength (570 nm) and enables one to construct calibration curves which accurately follow the Bee's law over wide ranges of analytical concentrations of both ions (2.0x10-6 M∼8.0x10-3 M for Cr2O72- ion, 2.0x10-6 M∼4.0x10-3 M for MnO4- ion)

AbstractAbstract
[en] Six column experiments were performed and seven breakthrough curves (BTCs) and seven displacement (desorption) curves (DPCs) of phosphate and U(VI) were obtained, which demonstrated the effects of phosphate and Cr3+ on the sorption and transport of U(VI) on a silica column at pH 3 and uranium concentration 10-5-10-6 mol/L of the influent. It was found that in the presence of phosphate sorbed preliminarily on the silica column, the amount of U(VI) sorbed on this column is significantly increased owing to the interaction of U(VI) with phosphate sorbed as compared with that in the absence of phosphate, and the breakthrough and the mean residence time of U(VI) on this column are similar to those in the absence of phosphate. While the effect of simultaneous injection of Cr3+ on the retardation of U(VI) on the silica column, the maximum concentration of BTC and the amount of U(VI) sorbed was found to be insignificant. Transport and sorption studies of U(VI) are important, since all uranium isotopes are radioactive, there is a need to understand the potential for migration away from radioactive waste storage and mill tailing sites.

AbstractAbstract
[en] The branch-like, feather-like BaCrO_4 nano-superstructures were synthesized with bioactive eggshell membrane as directing and assembly template. Studies on the two products revealed that they formed through the self-assembly of nanoparticles, and that the optical properties of the products were different from BaCrO_4 bulk materials
