Removing Active Species by Fullerenol in vitro and in vivo

Yin J-J., Lao F., Wamer W-G., Zhao Y., Gao X., Wang P-C, Chen C., Liang X-J., National Center for Nanoscience and Technology of China, CN

We previously demonstrated that gadolinium endohedral metallofullerenol ([Gd@C82(OH)22]n nanoparticles) had high inhibitory activity on growth of malignant tumor in vivo by uncertain mechanism(s). The activities of enzymes associated with the metabolism of reactive oxygen species [...]

Fabrication of Luminescent Superparamagnetic CdSe-QDs/SiO2/Fe3O4 nanocomposite particles

Liu B., Wang D., Huang W., Xie W., Yu M., Yao A., Tongji University, CN

A new kind of water-soluble luminescent superparamagnetic nanocomposite particles has been synthesized using a modified Stöber method combined with an electrostatic assembly process. Fe3O4 nanoparticles with the size of 10 nm were uniformly coated with [...]

A Portable Raman Sensor for the Rapid Identification of the Olive Oil

Qi X., Zhang X., Zou M., Chen Y., Ye J., Chinese Academy of Inspection and Quarantine, CN

The adulteration of the olive oil with lower-priced oils and its distinction of different classifications are serious problems in the olive oil market, a fast on-site screening method is needed to be developed. In addition [...]

Research on Preparation of Nano-Barium Titanate and Dielectric Property of Barium Titanate Ceramic Capacitor

Feng X., Liu X., Cui Y., Institute of Electronic Engineering, CN

In this paper ,a mild alcohol-thermal synthesis of nano-BaTiO3 from H2TiO3 and Ba(OH)2 at an Atmospheric Press was systematically studied and the optimized preparation conditions were obtained. When the reaction was carried out at a [...]

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 [...]
