    摘要： Organosilane-modified nanoparticles of silica, having a particle size of no more than 1 micron, in which the organosilane resides throughout the entire volume of the nanoparticles and not just at the surfaces of the nanoparticle. The nanoparticles may be in a colloidal solution. They may be prepared by hydrolyzing an alkali silicate under acidic conditions to obtain a silicic acid dispersion, followed by adding an organosilane having hydroxyl and/or hydrolyzable groups to the dispersion under acid conditions; and then raising the pH of the dispersion to at least eight to form the nanoparticles. They may be used in an effective paint primer/protective coating formulation.

    摘要： Provided is an electrochemical cell for generating hydrogen peroxide (H202) directly from water, and an application thereof. The electrochemical cell includes: water-soluble electrolyte; an electrode structure A, in which hydrogen peroxide is generated by oxidizing water containing city water (CW) or electrolytes when voltage of time dependant polarity is applied; and an electrode structure B, in which hydrogen peroxide is generated by reducing water of the water-soluble electrolyte when the voltage of time dependant polarity is applied, wherein the polarity reversal of the voltage Ve is performed periodically or non-periodically according to the time between positive (+) voltage and negative (−) voltage.
