摘要：
Viscosity is a first and foremost function both for theory and application. By approximating the interaction potential of molecule in fluidic fuel as constant and proposing a new method to calculate the momentum transfer by means of the radius of averaged volume per molecule, an equation of viscosity versus temperature was derived, which were found in good agreement with a lot of data from gaseous to liquid fuels by the curve fit. The equation also predicted that the viscosity initially decreased with temperature and then slowly increased in the high temperature region. When using it as correlation equation for the dependence of viscosity on temperature, it was able to cover more fluids from gaseous to liquid fuels. (C) 2015 Elsevier Ltd. All rights reserved.

摘要：
A kind of alcohol-soluble acrylate adhesive was synthesized by solution-polymerization. The influences of monomer ratio of soft to hard, function monomer and initiator content were studied on adhesive performance. The optimal conditions: ethanol as solvent, MA : MMA : AA : VAc = 4.5 : 4 : 1.5 : 2 : 0.8, and BPO is 0.8% of total mass, the temperature is 73 °C for 3.5 h. The properties of adhesive were determined.

摘要：
Two kinds of electroconvection patterns in an ether-bridged bent-core nematic liquid crystal material (BCN), which appear in different frequency ranges, are examined and compared. One is a longitudinal pattern with the stripes parallel to the orientation of the BCN and with a periodicity of approximately the cell thickness, occurring in the high-frequency range of several hundreds Hz; the other one is oblique stripes, which results in a zigzag pattern, and appears in the low-frequency range of several tens Hz. In addition, within an intermediate-frequency range, transformations from oblique to longitudinal and then to normal stripes occur at increased ac voltages. In particular, we investigated the temperature behavior of longitudinal and oblique stripes: When the temperature T increases and approaches the clearing temperature Tc, the contrast of the domains is enhanced and the frequency range of existence becomes wider, while the onset voltages increase only moderately instead of diverging, thus suggesting an isotropic mechanism of pattern formation.
摘要：
A novel wet-chemical method for the preparation of silver flakes was studied. The well-defined particles were prepared by directly adding FeSO_4 solution into AgNO_3 solution containing citric acid at an agitation speed of 150 r/min at room temperature. The products were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that particles are irregular thin silver flakes. And the sizes of them range from 2 to 10 μm. It is found that citric acid plays an important role in the formation of sliver flakes. There is an optimum amount of citric acid for the preparation of silver flakes by this method. It is also found that high reduction rate is favorable for the formation of silver flakes.

摘要：
Cleaner production is one of sustainable development approaches for wastepaper papermaking industry. Current situation of a wastepaper papermaking enterprise was analyzed, and it showed that the unit product energy consumption, pollutant generation had large cleaner production potential. 16 cleaner production solutions were generated through material balance analysis, advanced technologies collection, experts consultation and other ways. After the plans were carried out, 7.83% of pollutants were cut down, 7.62% of energy was saved, 1.57% of waste paper was reduced, 1.68% of dry fiber raw material was decreased, and 8.80% of reused industrial water increased equally. Cleaner production was an effective way for wastepaper papermaking industry to save energy, reduce energy consumption, reduce pollution, and increase benefit.
摘要：
The hierarchical nanostructured FeS2 hollow microspheres composed of nanoflakes were fabricated based on Ostwald ripening using sulfur powder as sulfur source and triethanolamine as both solvent and reducing agent, and electrochemically investigated as cathode material for lithium-ion batteries. The as-obtained FeS2 electrode delivered an initial capacity of 886.3 mA h g−1 at 0.1 C at ambient temperature, which is one of the highest values in the reported results. In the subsequent cycles following the first cycle, the electrode exhibited good reversibility at ambient temperature, resulting in good cycling stability and performance, and the discharge capacity of 392.7 mA h g−1 at 1 C was still retained after 30 cycles. This might be attributed to the unique FeS2 structure with hierarchical nanostructured hollow microspheres, showing potential to develop FeS2 cathode materials with high energy density for lithium-ion batteries.
摘要：
We have analyzed the photorefractive (PR) effect of a polymer composite was reported which combines a novel bi-functional poly(N-vinyl)-3-[p-nitrophenylazo]carbazolyl (PVNPAK) and 2,4,7-trinitro-9-fluorenone (TNF). PVNPAK was synthesized by a post-azo-coupling reaction, with an azo derivative as the electrooptic chromophore and carbazolyl as photoconductive moiety. The asymmetric two-beam coupling gain of 13.9 cm−1 and diffraction efficiency of 1.2% for poled polymer film fabricated using a corona poling are obtained at the wavelength of 647.1 nm, confirming photorefractivity. We interpreted this result as the orientational enhancement, in which the spatial charge field may enhance the modulated orientation of the azobenzen chromophore. It is unexpected that the photorefractive gain of 9.5 cm−1 for the unpoled polymer film also was observed without external field in two-beam coupling (TBC) experiment. This phenomenon is attributed to a light-induced orientational grating when the azobenzene groups are illuminated by polarized light.

摘要：
Porous spheres of TiO2 nanoparticles have been successfully prepared using cationic monomer as precursory solid and thermal decomposition at 500 oC. The product was characterized by X-ray powder diffraction and scanning electron microscope. The ultraviolet photocatalytic activity of the obtained materials was evaluated by decomposing 1-naphthylamine-4-azobenzene-4'-sulfonic acid. The porous spheric TiO2 exhibited a good photocatalytic activity. The degradation rate was about 96.5% for in contaminated water after 50 min irradiation by UV light.

摘要：
Titanium dioxide nanotubes (TDNTs) were used as a solid phase extraction adsorbent for chromium species by a packed microcolumn coupled with inductively coupled plasma mass spectrometry (ICP-MS), including total, suspended and soluble chromium as well as Cr(III) and Cr(VI) in tea leaves and tea infusion. The experimental results indicated that Cr(III) was quantitatively retained on TDNTs in the pH range of 5.0–8.0, while Cr(VI) remained in the solution. The total chromium was determined after reducing Cr(VI) to Cr(III). The concentration of Cr(VI) is calculated by the difference between total chromium and Cr(III). Under optimal conditions, the detection limits of this method were 0.0075 ng mL−1 for Cr(III). The relative standard deviation was 3.8% (n = 9, c = 1.0 ng mL−1). This method was applied for the analysis of the speciation of chromium and its distribution and content in tea leaves, tea infusion and a certified reference material of tea leaves with satisfactory results.
