Bedrov, Dmitro; Smith, Grant D. | Anomalous pressure dependence of the structure factor in 1,4-polybutadiene melts: a molecular dynamics simulation study | Neutron scattering has shown the first diffraction peak in the structure factor of a 1,4-polybutadiene melt under compression to move to larger q values as expected but to decrease significantly in intensity. Simulations reveal that this behavior does not result from loss of structure in the polymer... | Polymer melts; 1, 4-polybutadiene melts; Pressure; Structure factor | 2004-07 |

Liu, Feng | Geometric constant defining shape transitions of carbon nanotubes under pressure | We demonstrate that when a single-walled carbon nanotube is under pressure it undergoes a series of shape transitions, first transforming from a circle to an oval and then from an oval to a peanut. Most remarkably, the ratio of the area of the tube cross sections at the second transition over that ... | Geometric constant; Shape transitions; Carbon nanotubes; Pressure | 2004-03 |
