Water transport inside carbon nano-tubes (CNTs) has attracted considerable attention due to its nano-fluidic properties. its importance in nonporous systems. and the wide range of applications in membrane desalination and biological medicine. Recent studies show an enhancement of water diffusion inside nano-channels depending on the size of the nano-confinement. https://www.allpeoplesay.com/product-category/skincare-and-hygiene-products/
