Pt nanoflower with excellent catalytic activity towards H2O2 was deposited on the surface of a screen-printed carbon electrode using potentiostatic technique to fabricate a disposable sensor for point-of-care glucose testing. Glucose oxidase was embedded via Nafion film. Field Emission Scanning Electron Microscopy was used to characterize the microstructure and morphology of the enzymatic electrodes...
Ice accumulation on transmission lines, caused by freezing rain, wet snow or frost, is one of major problems influencing safety of electric power system. Super hydrophobic coating on insulators is a kind of efficient way to solve the problem. Many kinds of super hydrophobic coatings are widely used in power system, especially fluororesin based coating which is cheap and has good outdoor weathering...
Ferro ferric oxide(Fe3O4) nanoparticles have found application as contrast agents for magnetic resonance imaging and as targeted delivery of drugs. Their stabilization as carrier systems remains a problem. The cytotoxicity of vascular endothelial cells induced by uncoated Ferro ferric oxide nanoparticles were investigated in this study. EA.hy926 cells were incubated with fresh medium containing uncoated...
The fuller-serine was synthesized and then dissolved in the organic solvent and then the nanoparticle aqueous suspension of fuller-serine was prepared. The nanoparticle sizes and Zeta-potentials were obtained by TEM and a Zeta-patential instrument, respectively. The results indicated that the aqueous nano-particle suspensions were rather considerably stable with homogeneous size. The free radicals...
We prepared Ag/PMMA nanocomposite polymer film by a simple in situ synthesis and measured their linear and nonlinear optical properties to evaluate their potential applications to all-optical devices. The linear absorption spectrum has shown the increase of absorption intensity in the presence of Ag nanoparticles. Nonlinear optical properties were studied using Z-scan technique with 13 ns pulse duration...
