A Sonoelectrochemical Synthesis of Nanosized CdS on TiO2 Nanotube-Array for Enhancing Photoelectrochemical Reactivity

Wang C-L, Sun L., Yun H., Li J., Lin C.J., Lai Y.K., Lin C.J., Xiamen University, CN

The nanoparticles of CdS were precipitated onto a self-organized TiO2 nanotube array photo-electrodes by using sonochemical synthesis combining with constant current electrochemical deposition. It is indicated that the CdS nanoparticles with average diameter of 28.1 [...]

Surface Constructions of Nano-Micro Structured CaP Biomaterials and Their Biocompatibility

Lin C.J., Wang H., Hu R., Lai Y.K., Geng Z.W., Xiamen University, CN

In this work, we concentrated our attention to develop various methods for surface construction of of calcium phosphate (CaP) and their composite coatings, including octacalcium phosphate (OCP), hydroxyapatite (HAp), micropatterned titanium surface by using electrochemical [...]

Application of anatase TiO2 sol derived from peroxotitannic acid in crop plant diseases control and growth regulation

Cui H., Zhang P., Gu W., Chinese Academy of Agricultural Sciences, CN

Synthetic germicides have been widely used to control crop diseases. But they caused many problems such as environmental pollution and food safety issues. It has consequently become necessary to develop alternative methods for the control [...]

Fiber Optic Biosensors Detecting System of Laser Processing Micro Channels

Bai Z-C, Qin S-J, Zhang X., Guizhou University, CN

With the development of micromachining technology, smart micro sensors have been a very potential technology. Micro channels products fabricated by micromachining technology have been put into markets in last years, such as inkjet tube of [...]

Paclitaxel-functionalized aspragalan-calcium phosphate nanoparticles

He Q., Zhang X.Z., Yaun W.M., Zhau D.M., Fang Z.Q., Gang X.H., Nanjing Medical University, CN

Paclitaxel (PTX) is an important anticancer agent. Its aqueous solubility is very low; hence the available formulation of PTX for clinical use consists of Cremophor EL, which has been associated with several hypersensitivity reactions. In [...]

Synthesis and Biopharmaceutical Characterisation of a New Poly hydroxyethyl

Qi X-H, Lin W., He Q., Guan X-H, Nanjing Medical University, CN

A promising approach to improve drug delivery is to modify a polymeric backbone structure by means of copolymerization. Such obtained macromolecular prodrugs (polymer–drug conjugates) may offer many advantages compared to other drug delivery systems: increased [...]

Application of direct growth ZnO nanaotetrapods in field emission device

Zhang Q., Zhang Y., Qi J., Zhang Q., Zhang Y., Liao Q., Ye N., University of Science and Technology, Beijing, CN

In summary, we demonstrate the ZnO nanotetrapod synthesized by a simple vapor phase transport process can be good field emission emitters. The field emission measurement as-synthesized materials reveal that these samples have low turn-on field [...]

The Effect of Microstructure on I-V Properties in Si/SiO2 Film

Ma S.Y., Ma Z.-J., Ma S.Y., Ma Z.-J., Northwest Normal University, CN

P-type Si(100) wafers with 8~11 Ω•cm resistivity were used as substrates. The Si substrates were put into the magnetron sputtering device (JGP560B), and three kinds of Si/SiO2 film were fabricated using the R.F magnetron sputtering [...]

Influence of Al-Doping on the Optical Properties of ZnO films

Ma S.Y., Chen H.X., Glass J.T., Parker C.B., Northwest Normal University, CN

Al doped ZnO (AZO) thin films were deposited on glass substrates using the radio frequency reactive magnetron sputtering technique. The effect of Al concentration on the microstructure and the luminescence properties of the AZO thin [...]

A Markedly Cntrollable Adhesion of Superhydrophobic Sponge-like Nanostructure TiO2 Films

Lai Y., Lin C., Huang J., Zhuang H., Sunb L., Nguyen T., Xiamen University, CN

A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]
