Seed morphology characters of 9 species of Cynanchum Linn. were observed under stereoscope and environmental scanning electron microscope( ESEM). The results showed that the seeds of Cynanchum had some differences in shape,size and epidermal ornamentation among species. Seeds of Cynanchum Sect. Vincetoxicum were relat…
A novel silver ion selective electrode with its ionophore being a kind of organic/inorganic composite composed of silver sulfide and attapulgite has been prepared.Attapulgite is a type of natural inorganic polymer which has some properties similar to zeolite,such as a higher specific surface area and plenty of intercr…
In the present work, excited state intramolecular proton transfer (ESIPT) emission properties of a new ben- zotriazole derivative 4-formyl-2-(2H-benzotriazol-2-yl)- phenol (C1) were studied. 4-Formyl-2-(2H-benzotriazol-2- yl)-methoxy-benzene (C2), 4-formyl-2-(2H-benzotriazol-2- yl)-phenyl acetate (C3) and 4-methyl-2-(…
Hot ductility, stress- strain behavior and high temperature tensile fracture behavior of wrought 316LN stainless steel were investigated. Hot tensile tests were carried out on a Gleeble 1500D thermal simulator system at a strain rate of 0.5 s-1over the temperature range 650-1300℃. The percentage reduction of area(RA)…
Zein peptide-maltodextrin(pep-MD) conjugates were prepared by the Maillard reaction.Pep-MD conjugates co-assembled with α-tocopherol(TOC) to create composite nanoparticles by the desolvation method.The effect of fabrication parameters on nanoparticles was investigated.The size and α-potential of nanoparticles were aff…
Adding both La 3? and Co 3? was used to tune the microstructure and electrical properties of BiFeO3 (BFO) thin films, and Bi1-xLaxFe0.90Co0.10O3 thin films were grown on the SrRuO3-buffered Pt-coated silicon substrates by a radio frequency sputtering. A polycrystal- line structure with (110) orientation was shown in t…
In this study, polyethylene terephthalate (PET) waste from post-consumer soft-drink bottles and crude glycerol from the biodiesel industry were used for the preparation of polyols and polyurethane foams. PET waste was firstly depolymerized by the glycolysis of diethylene glycol. The glycolyzed PET oligomers were then…
Compared with traditional batteries, supercapacitors exhibit the high power density, long cycle life and wide operating temperature window. However, the relatively low energy density of supercapacitor still remains a challenge. In this paper, the structure, classification and development of supercapacitors are introdu…
In a beta radioluminescence nuclear battery, the beta energy is converted to light with the phosphor mate- rial, and then to electricity via photovoltaic cells. A method to optimize the thickness of phosphor layer is established in this study; the match between the luminescence spectrum and the photovoltaic cell is an…
修改电极由作为一个同类的调停人在一个传感器和萘粉绿色的电极合并 multiwall 碳 nanotubes 准备了的 multiwall 碳 nanotube 面对色氨酸(Trp ) 为 N-actylcysteine (N 交流) 的决心被用作一个 voltammetric 传感器。在有 Trp 的混合物的 N 交流的微分脉搏 voltammetry 的 voltammograms 被 200 mV 的潜在的差别与对方分开，它同时允许 N 交流和 Trp 的决心。在最佳条件下面， electrocatalytic 水流在 0.25400 mol/L (有不同斜坡的二个线性片断) 的范围与 N 交流集中线性地增加了。为 N 交流的…
Liquid crystals with dielectric and optical anisotropy have the ability of optical phase efficient modulation.When the liquid crystal system is placed in external electric field,the director of liquid crystal system will be redistributed.In this paper,the optical modulated effect of electronically controlled liquid cr…
我们在场在液体水晶(LC ) 的 amphiphilic 单层的阶段行为的纹理粗糙的分子的动力学模拟研究 /water 接口。结果表明在接口的 LC 能影响 amphiphiles 的侧面的订。特别地，与在尾巴之间的垂直地渗透的 LC 一起的 amphiphile 尾巴经历二尺寸的阶段转变从进他们在接口的区域密度到达 0.93 的一个压缩液体的阶段膨胀液体。当时，单层的压缩液体的阶段从来不出现在各向同性的形状油粒子的油 / 水接口。这些调查结果表明各向异性的 LC 的穿入能支持 amphiphiles 的订的侧面的组织。而且，我们发现当 LC 有更大的亲密关系到 amphiphile 尾巴时，阶段转变点被转移降低 amphiphi…
合金一超离频在象为超过 3.1% 的塑料紧张的高能力一样的 1010MPa 上面的压缩力量。电气化学并且沉浸测试表明这些做 Y 的 Mg–Zn–Ca 合金在 37 °C 在模仿的身体液体(SBF ) 有好简历腐蚀抵抗。cytotoxicity 测试的结果为这些合金显示出高房间生存能力，它意味着好简历相容性。
A series of Pd/La-Al2O3(PLA) catalysts with La-Al2O3(LA) support calcined at different temperatures(500, 700, 900 and 1050 oC) were prepared using an incipient wetness impregnation method. The activity of the fresh and hydrothermally aged PLA catalysts were tested for total oxidation of CO and C3H8. The activity of th…
The corrosion behavior of a grounding material Q235 steel was investigated in an artificial acid soil made of diatomite. Steel coupons were buried for 15 d in the artificial soil with different water contents in a range 10% to 50%. The results indicated that the water content had a great effect on corrosion behavior o…
