Smith, Grant D.; Bedrov, Dmitro; Borodin, Oleg | Structural relaxation and dynamic hetrogeneity in a polymer melt at attractive surfaces | Molecular dynamics simulations of polymer melts at flat and structured surfaces reveal that, for the former, slow dynamics and increased dynamic heterogeneity for an adsorbed polymer is due to densification of the polymer in a surface layer, while, for the latter, the energy topography of the sur... | Polymer melts; Structural relaxation; Dynamic heterogeneity; Attractive surfaces; Surface energy topography; Polymer densification | 2003-06 |

Liu, Feng | Hydrogen induced Si surface segregation on Ge-covered Si(001) | Using Fourier transform infrared-attenuated total reflectance spectroscopy in conjunction with hydrogen adsorption to probe surface layer composition, we observe a reversible place exchange between Ge and Si on Ge-covered Si(001) when the surface is dosed with atomic H at elevated temperatures.

Furse, Cynthia M. | Impedance of a short dipole antenna in a magnetized plasma via a finite difference time domain model | The traditional analytical analysis of plasma probes requires the use of quasi-static approximations, while numerical methods require the use of an equivalent dispersive media, both producing a nontrivial analysis of the plasma environment. On the other hand, a few techniques that combine the plasm... | Antenna theory; finite-difference time-domain; FDTD; Plasma covered antennas; Plasma measurements | 2005-08 |
