Most atomistic simulation studies of polyethylene employ a united-atom representation to reduce complexity and computational costs. The ramifications of such an approximation have been discussed with respect to structural properties…
conductive polymers are potentially useful as heat spreaders and could supplement conventional metallic heat-transfer materials, which are used in applications such as solar hot-water collectors, heat exchangers and electronic packaging….
character and thus may contribute to heat conduction in a fundamentally different way than is described by PGM. For the modes in crystals, which have sinusoidal character, one can separate…
to structural disorder. Using vertically aligned arrays of nanofibres, we demonstrate effective heat transfer at critical contacts in electronic devices operating under high-power conditions at 200 °C over numerous cycles….
°C. Such high temperatures place severe limits on heat transfer fluids; that is, such fluids would need to remain chemically stable, and be compatible with containment materials, at such extreme…
thermal conductivities exhibit excellent agreement with experiments and anharmonic effects are included in the thermal conductivity calculation for all the modes in a-SiO2 for the first time. Previously, localized modes…
of the modes in the structure. Using the recently developed interface conductance modal analysis (ICMA) method along with a new complimentary methodology, we mapped the correlations between modes, which revealed…
To control receptor tension optically at the cell surface, we developed an approach involving optomechanical actuator nanoparticles that are controlled with near-infrared light. Illumination leads to particle collapse, delivering piconewton…
using a combination of lattice dynamics, molecular dynamics (MD) and experimental thermal conductivity data, we back-calculated the phonon velocities for the vibrational modes. The results of this approach show that…
coupling between material properties and reactor operating conditions. Herein, we describe a new framework for material comparison which employs a thermodynamic reactor model to predict the maximum possible efficiency of…
