Superior thermal conductivity and extremely high mechanical strength in polyethylene chains from {\it ab initio} calculation [PDF]
J. Appl. Phys. 111, 124304 (2012), 2012 The upper limit of the thermal conductivity and the mechanical strength are predicted for the polyethylene chain, by performing the {\it ab initio} calculation and applying the quantum mechanical non-equilibrium Green's function approach. Specially, there are two main findings from our calculation: (1).

Temperature Dependent Neutron Scattering Sections for Polyethylene [PDF]
Nucl.Instrum.Meth.A538:686-691,2005, 2003 This note presents neutron scattering cross sections for polyethylene at 296 K, 77 K and 4 K derived from a new scattering kernel for neutron scattering off of hydrogen in polyethylene. The kernel was developed in ENDF-6 format as a set of S(alpha,beta) tables using the LEAPR module of the NJOY94 code package. The polyethylene density of states (from 0

Topological Twistons in Crystalline Polyethylene [PDF]
, 1998 We introduce an alternate model to describe twistons in crystalline polyethylene. The model couples torsional and longitudinal degrees of freedom and appears as an extension of a model that describes only the torsional motion. We find exact solutions that describe stable topological twistons, in good agreement with the torsional and longitudinal ...
