Reaction of 3-aminopropylsilyl-modified ZnO microrods with trioctylphosphineoxide-coated CdSe/CdS core/shell nanocrystals in THF produces rod-shaped nanoparticle clusters that show directional photoemission that can be tuned with the size of the CdSe nanocrystals. The observed waveguiding effect of these microstructures is due to total internal reflection of light at the cluster-air interface.

O6-Ethylthioethyldeoxyguanosine has been synthesized from 6-chloro-3',5'-di-O-acetyldeoxyguanosine and characterized by UV, fluorescence, and mass spectrometry. High-pressure liquid chromatography studies have shown that this modified nucleoside is formed when the one-armed sulfur mustard, chloroethyl ethyl sulfide, reacts with deoxyguanosine. This result supports the hypothesis that the mutage...

Semiconducting oxide nanobelts of ZnO have been sectioned and manipulated, for microelectromechanical systems, using an atomic force microscopy probe. Structurally modified nanobelts demonstrate potential for nanocantilever based technologies. With dimensions ;35– 1800 times smaller than conventional cantilevers, the nanocantilevers are expected to have improved physical, chemical, and biologic...

Nanoscale cell injection techniques combined with nanoscopic photoluminescence (PL) spectroscopy have been important issues in high-resolution optical biosensing, gene and drug delivery and single-cell endoscopy for medical diagnostics and therapeutics. However, the current nanoinjectors remain limited for optical biosensing and communication at the subwavelength level, requiring an optical pro...

in recent years, zinc oxid nanotubes have attracted much attention. the direct use of , zinc oxidnanotubes modified by sio2 as recoverable catalysts for organic reactions is very rare. the catalystswere characterized by xrd. the average particle size of zno catalysts is 57 nm and there are highdensitydefects on nanotubes surfaces . a simple and efficient method for the imidazol derivativessynth...

mold powders in continuous casting of steel contain fluorine through mainly caf2 and occasionally naf andna3alf6. fluorine develops dangerous gases such as sif4 and hf at high temperatures. in this study, caf2 is partly replaced by substances such as na2co3, zno and fe2o3.sulfur free portland cement clinker containing gypsum was used as a new product base. these additions developed comparable v...

Different composites based on ZnO/Ag3PO4 and ZnO–malachite (Cu2(OH)2CO3) were synthesized in order to determine their effectiveness the treatment of municipal industrial wastewaters (mainly polluted by enteropathogenic bacteria, dyes, heavy metals). The addition Ag3PO4 malachite did not significantly modify physicochemical properties ZnO; however, optical this oxide modified as a result its cou...

Distinguishing a specific biomarker from a biofluid sample containing a large variety of proteins often requires the selective preconcentration of that particular biomarker to a detectable level for analysis. Low-cost, paper-based device is an emerging opportunity in diagnostics. In the present study, we report a novel Zinc oxide nanorods functionalized paper platform for the preconcentration o...
