Research Abstract

By using a technique of quartz crystal microbalance, as a nanosensing method, adsorption and desorption behavior of food deposit on solid surface was detected with accuracy. Furthermore, an atomic scale mechanism of adsorption of food deposit on solid surface was revealed by molecular dynamics simulation, a virtual nanosensing method. These accomplishments will be useful hints for energy and resource saving or more advanced cleaning technology.
