  12. Hydration Dynamics in an Amphiphilic Nanostructure under Controlled Hydration Conditions

    16 Sep 2008 | | Contributor(s):: Amitabha Chattopadhyay

    Amphiphilic surfactants self assemble to form reverse (or inverted) micelles in non-polar solvents in which the polar head groups of the surfactant monomers cluster to form a micellar core directed toward the center of the assembly and the hydrophobic tails extend outward into the bulk organic...

  13. Nano Carbon: From ballistic transistors to atomic drumheads

    14 May 2008 | | Contributor(s):: Paul L. McEuen

    Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an impenetrable membrane a single atom thick. Rolled up into a nanometer-diameter cylinder--a carbon...
