Assoc. Prof. Dr. Warakorn Limbut and TAB-CoE team was invited to give a special talk about the innovation of disinfectant in the topic of “The Production of Hypochlorous acid (HOCl) from Electrochemical Device”. The new device produces HOCl, which can kill bacteria and other pathogens, and then HOCl solution is sprayed in the form of mist that can increase the efficiency of killing bacteria and pathogens. This device can be applied to clean any equipment, materials, or areas for both inside and outside. The talk was given on Tuesday 14th April 2020 at Pattana Brigade 4, Rattanaphon Camp, Khlong Hoi Khong District, Songkhlai, Thailand.
