Abstract: A method of accelerating liquor aging process includes acts of preparing a liquor having by-products, preparing a nano-gold surface by sputtering gold nanoparticles onto a substrate, barreling the liquor and the nano-gold surface into a barrel, circulating the liquor and removing a product of artificially aged liquor. The liquor is circulated by a pump for increased rate of diffusion and incidences of collision between the by-products and nano-gold surface. The gold nanoparticles serve as a catalyst to promote oxidation of by products including formaldehyde, acetaldehyde and fusel alcohols in the liquor into organic acids and esterification of organic acids to accelerate the liquor aging process of the. After the product is removed, the nano-gold surface can be recycled. The gold nano-particles do not aggregate or precipitate in the liquor, therefor, perform more predictably so reduce manufacturing costs and improve consistency of manufacture.

Abstract: A disinfective adhesive tape has a carrier layer, a silver nanoparticle layer and an adhesive layer. The carrier layer has a top surface and a bottom surface. The silver nanoparticle layer is formed on the top surface of the carrier layer and comprises multiple silver nanoparticles. The adhesive layer is applied to the bottom surface of the carrier layer. The disinfective adhesive tape can be applied in any article and act as a disinfectant during daily use.
