Or Yehuda, Israel (PRWEB) July 23, 2007 -- Do-Coop Technologies Ltd is proud to announce the release of a paper regarding rf irradiation and nanoparticle doaping of water by Prof Aharonov and Prof. Ben-Jacob.
T he paper "The Effect of rf-irradiation on Electrochemical deposition and its Stabilization by Nanoparticle Doping" submitted by Yael Katzir, Lior Miller, Prof Yakir Aharonov and Prof Eshel Ben-Jacob, was recently published in the 'Journal of the Electrochemical Society.'
The paper depicts the effect of the transiently altered physical properties of rf-irradiated water on the sedimentation patterns during electrochemical deposition as well as the stabilization of these changes and thus the depicted effects by Nanoparticle doping of the irradiated water.
Qualitative observations of electrochemical deposition in thin circular cells have shown that radiofrequency irradiation of Zinc sulphate solutions can dramatically affect the deposition patterns. For some growth parameters the rf-treatment can even induce morphology transitions between the dense branching morphology and dendritic growth. We found that the effects of rf-treatments can last for long time (hours).
In addition, detailed studies using electron microscopy observations reveal that the effects span on all scales, from the micron-scale organization to the selforganization of the macroscopic pattern. We propose that these changes of patterning on all scales resulted from singular effects of gas-filled submicron bubbles or nanobubbles, which are generated by the rf-irradiation. The idea is that hydration shells around the nanobubbles induce water ordering that acts as a new singular perturbation mechanism in the solution.
The latter is in addition to the well studied micro-scale singular perturbation mechanisms in the deposit (surface tension and attachment kinetics). Electrochemical deposition in Zinc sulphate solutions prepared from water that is doped with nanoparticles under rf-irradiation were also studied, and similar and even amplified effects were found. Moreover, the nanoparticle doping stabilizes the effects -- they are retained months after the solutions were prepared.
