Abstract When argon is used as a protecting gas in the fabrication or working environment of a nanodevice. absorption of some argon atoms onto the surface of the device lead to different responses. In this work. the rotation of the rotor in a carbon nanotube (CNT)-based rotary nanomotor in argon environment is investigated. https://www.kingarte.com/product-category/food-servicecommercial-kitchen-equipmentcleaning/
