Preparation of “Cauliflower-Like” ZnO Micron-Sized Particles
Porous polydivinyl benzene (PDVB) microspheres of narrow size distribution were formed by a single-step swelling process of template uniform polystyrene microspheres with divinyl benzene (DVB), followed by polymerization of the DVB within the swollen template microspheres. The PDVB porous particles were then formed by dissolution of the template polystyrene polymer. Unique "cauliflower-like" Zn...
متن کاملReal-time optical imaging and tracking of micron-sized particles
We report real-time imaging and dynamics monitoring of micrometer predefined and random sized particles by time–space-wavelength mapping technology using a single-detector. Experimentally, we demonstrate real-time line imaging of a 5 lm polystyrene microsphere, glass powder particles and patterns such as fingerprints with up to 5 lm resolution at 1 line/50 ns capture rate. By using the same set...
متن کاملNMR investigations of silane-coated nano-sized ZnO particles
Si, Xe and C NMR is used to investigate a porous material consisting of nano-sized ZnO particles coated by silane molecules. These materials are synthesized by a novel sol–gel procedure where the nanoscale ZnO particles are formed in the presence of the coating material 3-methacryloxypropyl-trimethoxysilane (‘‘silane’’). The BET specific surface of the uncoated particles, synthesized by the sam...
متن کاملA Simple Method for Preparation of Nano-sized ZnO
Nano is an advanced technology which in recent years has had numerous applications in different fields such as industry, biotechnology, energy, environment and etc. In this paper, ZnO nanoparticles were synthesized by simple method of precipitation sounds more plausible. ZnSO4 and NH4OH were used as precursors to yield ZnO powders. The synthesized ZnO nanoparticles were characterized by X-ray d...
متن کاملPreparation, Characterization and Stabilization of Nano- sized Copper Particles
Cu nanoparticles dispersed in water were prepared by the reduction of Cu originated from the copper salt solution. The stability of the Cu nanoparticles in dispersion was monitored through the analysis of the absorbance spectra at different stages during the process of synthesis. The stability of the Cu nanoparticles dispersed in aqueous medium was investigated after different time intervals. C...
