4. Computational Nanoscience, Lecture 5: A Day of In-Class Simulation: MD of Carbon Nanostructures

   5.0 out of 5 stars 

   Teaching Materials | 13 Feb 2008 | Contributor(s):: Jeffrey C Grossman, Elif Ertekin

   In this lecture we carry out simulations in-class, with guidance from the instructors. We use the LAMMPS tool (within the nanoHUB simulation toolkit for this course). Examples include calculating the energy per atom of different fullerenes and nantubes, computing the Young's modulus of a nanotube...

   Online Presentations | 16 Apr 2007 | Contributor(s):: SeongJun Heo, Susan Sinnott

   The mechanical properties of carbon nanotubes are studied by using classical molecular dynamics simulations. Especially, the effects of filling, temperature, and functionalization on CNT's tensional and twisting properties are considered in this study.

7. Orientational Dependence of Friction in Polyethylene

   Online Presentations | 16 Apr 2007 | Contributor(s):: SeongJun Heo

   The frictional properties of polyethylene polymer are investigated by using classical molecular dynamics simulations. Especially, the sliding orientational effect is considered in this study. The results of polyethylene are also compared to those of polytetrafluoroethylene(PTFE).
