Limitations of dielectrophoretic (DEP) assembly for gold particles and optical dielectrophoretic (ODEP) manipulation of spherical particles are theoretically analyzed in this article. The results in the "Gold Nanoparticle Assembly" section reveal that the core-shell sphere polarization model is effective for characterizing the frequency-dependent mechanism of DEP manipulation, which concludes...
The nucleation, growth, and coalescence of silver oxide nanoparticles have been investigated dynamically and at high spatial resolution by using the electron beam of a transmission electron microscope to stimulate and to observe the processes. Under the assumption the particles are hemispherical, the growth rate was found to be proportional to the square root of the electron irradiation time. This...
The use of an electroneutral ligand modified the Cd 2+ -rich surface of CdS leads to the surrounding of CdS/2,2′-bpy by the counter ion (anion) to balance the charge of the Cd 2+ ions, resulting in the CdS cluster with strong electrolyte behavior.
