  4. ABINIT: First-Time User Guide

    09 Jun 2009 | | Contributor(s):: Benjamin P Haley

    This first-time user guide provides an introduction to using ABINIT on nanoHUB. We include a very brief summary of Density Functional Theory along with a tour of the Rappture interface. We discuss the default simulation (what happens if you don't change any inputs, and just hit "simulate") as...

  5. Nanotribology, Nanomechanics and Materials Characterization Studies

    08 Jun 2009 | | Contributor(s):: Bharat Bhushan

    Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...
