20_15/2010Nanotubes: A Closer Look Inside Nanotubes: Pore Structure Evaluation of Anodized Alumina Templated Carbon Nanotube Membranes Through Adsorption and Permeability Studies (Adv. Funct. Mater. 15/2010)

In the “heart” of nanotubes. The internal morphology of carbon nanotubes (CNTs) is assessed by investigating the permeability and adsorption behavior of selected gases and vapors through CNTs that have been grown inside the channels of an anodized alumina template, as presented by G. E. Romanos, G. N. Karanikolos, and co-workers on page 2500. The cover illustrates template-free aligned CNTs in a heart-like configuration. Internal restrictions, surface roughness, hollow space narrowing, and other inside-tubes characteristics are determined that are crucial in CNT storage and flow-through applications.
