By analyzing the research results of scholars overseas and domestic in recent years, the main structural factors which impact sampling efficiency were ascertained. They are the ratio of inlet height to width, the channel length, and material of hop-pocket. According to the sand sampler for performance test requirements, different construction parameter sand samplers were designed and tested in the wind erosion tunnel. The results indicate that the average sampling efficiency to soil particles of 0.15-0.60 mm is higher than intermixed dust and 0.15 mm under 6, 9, 12, 15, 18 m/s wind speed. The sampler is applicable to the acquisition of soil particles with the form of jump movement. The order of structural factors that affect sampling efficiency is the ratio of inlet height to width, the channel length, and material of hop-pocket. And the ratio of inlet height to width is the most remarkably factor. By the variance and range analysis, the optimization structure parameter of the sand sampler is as follows: the ratio of inlet height to width is 0.5, the channel length is 20 cm and the material of hop-pocket is falda. Under this situation, the average sampling efficiency of the sand sampler is 80.91%.

Chitosan (CS) with two different molecular weight were modified by reacting with methyl hydrazine-dithiocarboxylate and methyl phenylhydrazine-dithiocarboxylate to give 2-(hydrazine-thiosemicarbazone)-chitosan (2-HTCHCS, 2-HTCLCS) and 2-(phenylhydrazine-thiosemicarbazone)-chitosan (2-PHTCHCS, 2-PHTCLCS). The structure of the derivatives was characterized by FT-IR spectroscopy and elemental analysis. The antioxidant activities of the derivatives were investigated employing various established systems, such as hydroxyl radical (OH)/superoxide anion (O2 .-) scavenging/reducing power and chelating activity. All of the derivatives showed strong scavenging activity on hydroxyl radical than chitosan and ascorbic acid (Vc), and IC50 of 2-HTCHCS, 2-HTCLCS, 2-PHTCHCS and 2-PHTCLCS was 0.362, 0.263, 0.531 and 0.336mg/mL respectively. The inhibitory activities of the derivatives toward superoxide radical by the PMS-NADH system were strong. The results showed that the superoxide radical scavenging effect of 2-[phenylhydrazine (or hydrazine)-thiosemicarbazone]-chitosan were higher than that of chitosan. The derivatives had obviously reducing power and chelating activity. The data obtained from vitro models clearly establish the antioxidant potency of 2-[phenylhydrazine (or hydrazine)-thiosemicarbazone]-chitosan. © 2010 Elsevier B.V.

Several ternary complexes of rare earth ions (RE 3+ = Sm 3+, Eu 3+, Tb 3+, Dy 3+) with benzoic acid and a neutral ligand 2,4,6-tri(2-pyridyl)-s-triazine (TPTZ) have been synthesized. The crystal structure of the [Eu(C 6H 5COO) 3(TPTZ)(H 2O)] 2·2C 2H 5OH·1.25H 2O complex was determined by single-crystal X-ray diffraction and it is characteristic of triclinic with P-1 space group. Especially, the crystal has two types of coordination environment. One is mononuclear and the other is dinuclear. Each europium ion is nine-coordinately bonded to three nitrogen atoms of TPTZ, five oxygen atoms of three benzoic ions and one oxygen atom of water molecule. Furthermore, there exist three coordinate forms between C 6H 5COO - and Eu 3+ ions in the crystal. One is chelating bidentate (two oxygen atoms), another is bridge coordinating (two oxygen atoms) and the other is monodentate (one oxygen atom). The compositions of these ternary complexes were characterized by elemental analysis, rare earth coordination titration, molar conductivity measurement, 1H NMR spectroscopy, IR spectroscopy and UV-vis absorption spectroscopy. The luminescence spectra and luminescence decay time were then studied. The luminescence intensities of the ternary complexes may result from the antenna effect of TPTZ and benzoic acid ligands as well as the reduce of solvent-quenching effect. Moreover, these ternary complexes exhibited superior antibacterial activity against Escherichia coli. © 2012 Elsevier B.V. All rights reserved.

The hot compressive deformation characteristics of ZK31-1.5Ymagnesium alloy were investigated in the deformation temperature range of 523~723 K and the strain rate range of 0.001~1 s-1. Based on dynamic materials modeling (DMM), the processing map was established. Combined with the true stress-strain curves the hot deformation mechanism and the optimal processing parameters of ZK31-1.5Y alloy was worked out. The results show that the softening mechanism of dynamic recrystallization and dynamic recovery is a feature of high-temperature true stress-strain curves of ZK31-1.5Y alloy, the peak stress and steady stress increase greatly with decreasing of the deformation temperature or increasing of the strain rate. According to the results, the obtained power dissipation maps and flow instability maps present three peak domains of power dissipation, and one instability zones of flow behavior of ZK31-1.5Y alloy, respectively, and the peak efficiency is 38%~65%. The optimum processing parameters of hot deformation in the range of this experiment can be attained by the processing maps, i.e. the hot deformation temperature ranging from 623 K to 723 K and the strain rate ranging from 0.1 to 1 s-1. Meanwhile, the characteristics of hot processing have not obvious variation with increasing of the strain ranging from 0.1 to 0.6.

In order to improve the understanding deformation behaviors of thermal compressive of ZK30 magnesium alloy, carried out a series of thermal compressive tests with height reduction 60% of specimens were performed at deformation temperature range of 523-673 K, and strain rates range of 0.001-1 s-1 on Gleeble-1500 thermo-mechanical simulator. Based on an Arrhenius-type equation constructs a nonlinear flow model and its constitutive equation, are employed to study the deformation behavior and the relationship between deformation temperature, strain rate and flow stress. For higher deformation temperature and lower strain rate, the true stress-strain curves show a characteristic of dynamic recrystallization. With the increase of deformation temperature and the decrease of strain rate the flow stress decreases, also the dynamic recrystallization becomes easier. © (2014) Trans Tech Publications, Switzerland.

The effects of 1 wt% Y addition on hot compressive deformation properties of Mg-3.0Zn-0.6Zr alloy were investigated in the deformation temperature range of 523~723 K, and the strain rate range of 0.001~1 s-1 by Gleeble-1500 thermal simulation test machine. Based on dynamic materials modeling (DMM), the processing map for the test alloys was established. The influences of yttrium element on the plastic strain mechanism and processing parameter of these alloys were indicated by means of optical microscope, scanning electronic microscope and X-ray diffractometer, combined with the true stress-strain curve characteristics and microstructure evolution. The results show that the flow stress is significantly affected under different deformation conditions. The flow stress level increases with either decreasing deformation temperature or increasing strain rate. The rare-earth Y doping could effectively enhance the stress level, risen by roughly 40%, but the change trend of these curves is less affected. Additionally, the addition of yttrium element can extend power dissipation zone, which has a peak efficiency enlarged by 22%, and the peak is transferred to the 673~723 K, 0.1~1 s-1 zone, and the instability zones of flow behavior is to reduce to 523~723 K, 0.001~0.01 s-1 saddle-shaped range of the alloy including 1% yttrium. Finally, the transfer of the optimum processing parameters of hot deformation from the high deformation temperature and low strain rate range to the temperature ranging from 523 to 723 K and the strain rate ranging from 0.1 to 1 s-1 can be attained by the processing maps.

The influence of the polarization direction of light-induced refractive index change (Δn) induced by light irradiation in In:Fe:LiNbO3 crystals were investigated by using ordinary and extraordinary recording polarization (opol/epol) laser beams of low-power near infrared light. The experimental results show that the curves are similar of the refractive index distribution, but they have opposite signs, and a further difference is that the saturation refractive index change is clearly larger for ordinary recording polarization, changing to extraordinary recording polarization result only about one-third. The refractive index change in photorefractive crystals induced by two polarization directions of near infrared light is differ from visible light. The crystal illuminated with extraordinary polarized light in the middle of the irradiation region, one can see a strong increased of the refractive index. Moreover, the results can be very useful for fabrication of tailored nonlinear optical device with different refractive index distributions by changing different the polarization directions of near infrared beam.

The homopolymer of 6-vinyl bisferrocenylpropane and copolymer of 6-vinyl bisferrocenylpropane and 6,6'-divinyl bisferrocenylpropane were obtained from ferrocene and acetone via a series of reactions. The monomers and polymers were characterized by elemental analyses, IR spectra and IHNMR. The thermal stabilities of the polymers were studied through DTA-TG. The results show that the solubility of the copolymer of 6-vinyl bisferrocenylpropane and 6,6'-divinyl bisferrocenylpropane is very poor and its thermal stability is obviously higher than the homopolymer of 6-vinyl bisferrocenylpropane. The reason for it is that the monomer of 6,6'-divinyl bisferrocenylpropane has two vinyl groups, so the grafting degree of the corresponding polymer is much larger than the homopolymer of 6-vinyl bisferrocenylpropane. © (2013) Trans Tech Publications, Switzerland.

The copolymers of 6-vinyl bisferrocenylpropane with vinylbenzene, methyl acrylate and methyl methacrylate, respectively, were obtained from ferrocene and acetone via a series of reactions. The monomer and polymers were characterized by elemental analyses, IR spectra and 1H NMR. The thermal stabilities of the polymers were studied through DTA-TG. The results show that the copolymer of 6-vinyl bisferrocenylpropane with vinylbenzene decompose in higher temperature than the copolymer of 6-vinyl bisferrocenylpropane with methyl acrylate or methyl methacrylate, indicating that the introduction of the phenyl group to the polymer can improve the thermal stability of the polymer. The decomposing temperature of the copolymer of 6-vinyl bisferrocenylpropane with methyl methacrylate is a little higher than the copolymer of 6-vinyl bisferrocenylpropane with methyl acrylate, indicating that the introduction of the methyl group to the polymer can slightly improve the thermal stability of the polymer. © 2015, Chemical Publishing Co.
