The molecular dynamics (MD) method is used to investigate the influence of the shielding gas on the dynamic behavior of the heterogeneous rotation transmission nano-system (RTS) built on carbon nanotubes (CNTs) and boron nitride nanotube (BNNT) in a helium environment. In the heterogeneous RTS. the inner CNT acts as a rotor. the middle BNNT serves as a motor. https://www.marketingjeunesse.com/product-category/straight-keep-shampoo/
