The corrosion behavior of Zn and 55%Al-Zn alloy coatings was studied by salt spray test which is designed to simulate the practical service situation, coupling with measurments of polarization curves and electrochemical impedance spectroscopy(EIS) as well. While corrosion products were characterized by XRD. The result…
This paper describes orientation dependence of magnetic properties on undeformed and deformed low carbon steel. Magnetic parameters have no changes for undeformed specimen when the direction of applied field changes, while the coercive force decreases and the inductance, the resistance increases with increasing the an…
The effect of the amount of precipitant ammonia on the Cu0/Cu+ratio of Cu/Si O2 prepared by the deposition–precipitation method is investigated. Species at different preparation stages, resulted from the amount of ammonia used, are identified by the XRD and FTIR techniques. Chrysocolla together with either copper nitr…
The CuSO4-catalyzed surface-initiated conventional radical graft poly- merization of electron-deficient monomers such as N,N-dimethylacryamide (DMAAm) was carried out from amino-functionalized SiO2 nanoparticles (SiO2- NH2) to directly prepare hybrid SiO2 nanoparticles (SiNPs) chemically grafted with functional poly(N…
Cylindrospermopsis raciborskii N8 strain was isolated from a sub-tropical reservoir in southern China and cultured with BG-11 culture medium. The effects of temperature,irradiance and nitrate on the growth of this strain were evaluated by a designed experiment with gradients of temperature( 12,16,20,24,28,32℃),irradia…
In this work, we have developed a novel visual Hg 2? sensor in aqueous solution using unmodified Au@Ag core-shell nanoparticles at room temperature, based on a redox reaction between Ag-shell and Hg 2? . The prepared Au@Ag core-shell nanoparticles exhibited good mono- dispersity. In the presence of Hg 2? ,H g 2? was r…
The precipitates and hydrogen permeation behavior in three kinds of hot rolled low carbon heavy plate steels for enameling were analyzed;then,both sides of the steels were enameled.The experimental results show that a large amount of coarse Ti4C2S2 and fine Ti(C,N) particles exist in the optimized Ti-bearing steel,qui…
A coordination polymer formulated as([Mn2L（N3）4]-2H2O}n（1）(L= 1,4-bis（pyridinil-3-carboxylato）-l,4-dimethylbenzene]was synthesized and structurally and magnetically characterized.The uniform Mn（II）chains with mixed（μ-EO-N3）2（μ-COO） triple bridges（EO = end-on） are linked by L ligands to generate a2-fold interpenetratin…
The screened electron-electron interaction in a multi-band electron system is calculated within the random phase approximation and in the tight-binding representation. The obtained dielectric matrix contains, beside the usual site-site correlations, also the site-bond and bondbond correlations, and thus includes all p…
和 AlO ) 能在 TAC-1 的表面上被检测，当没有腐蚀产品出现在 TAC-2 时。在 TAC-1 的金属矩阵的不一致的元素分发导致了局部性的腐蚀并且相对与 TAC-2 相比的差的腐蚀电阻。
ss -AuNRs,金使nanorod具有感光性结合包含 pH (低)有给予细胞外的 pH 的一张二硫化物契约的插入肽( pHLIP )( pH e )-driven 肿瘤指向能力，成功地为光力学的 bimodal 和 photothermal 治疗被开发了。在这 bimodal 治疗，氯 e6 (Ce6 ) ，第二代的 photosensitizer (PS ) ，被用于光力学的治疗(太平洋夏季时间) 。金 nanorods (AuNRs ) 作为 Ce6 的 nanocarrier 和 quencher 为 photothermal 治疗(PTT ) 并且也被用作一个过高热代理人。pHLIPss 作为一根驾驶 pHe 的指向探…
The synthesis and in vitro photodynamic anticancer activity of a new photosensitizer, tetra(trifluoroethoxy) germanium phthalocyanine(GePcF), were studied. GePcF was characterized by UV-Vis, IR, MS and elemental analysis. The in vitro photodynamic activity of GePcF was studied by MTT. IC50 of GePcF for SW480 cells of…

Magnesium-bearing minerals discovered on the earth so far occur mainly as solid or liquid.The former include magnesite(Mg CO3),dolomite(Mg CO3·Ca CO3),carnallite(Mg Cl2·KCl·6H2O),bischofite(Mg Cl2·6H2O)and
热转动、一致的 Cu-Zn-Al 形状记忆合金(SMA ) 的不同碎片受到借助于微分扫描 calorimetric (DSC ) 的热骑车设备。当冷却以减少的温度的不同的率被执行时，在热骑车期间，加热以增加温度的一样的经常的率被执行。为每冷却的率，温度在一样的热间隔减少了。在每个冷却阶段期间，一座发热的山峰(最大值) 在 DSC thermogram 上被观察。这座山峰与前面的 martensitic 转变被联系。DSC thermograms 用盲螈属软件被分析：批评 martensitic 转变开始(女士) 并且完成(Mf ) 温度借助于积分和正切方法被决定，并且驱散的热由在相应最大的阴谋和一条 S 字形的基线之间的区域被评估…
Graphene is a basic unit for various types of sp2 carbon forms and its emergence brings new opportunities to construct carbonaceous materials with desired structure and function. Controlled preparation of novel carbonaceous functionalized materials can be achieved by graphene/graphene oxide assembly in solution and te…
We prepared chondroitin sulfate (ChS)- chitosan (CS) nanoparticles (NPs) as a delivery carrier, and doxorubicin (Dox) was used as a model drug.
