TL;DR: In this article, the authors use molecular dynamics simulations to study heat transport in polynorbornene, a polymer that can be synthesized in semi-crystalline form using solution processing.

TL;DR: Yang et al. as discussed by the authors proposed a method to solve the problem of particle filtering in the context of physics and applied it in the field of computer science at the Massachusetts Institute of Technology (MIT).

TL;DR: An optical method is used to probe heat conduction at submicrometer length scales, allowing for direct observation of thermal phonons with mean free paths up to 200 nm in semicrystalline polyethylene films using transient grating spectroscopy, yielding insights into the microscopic origins of their high thermal conductivity.

TL;DR: In this article, the authors derived a generalization of the Fuchs-Sondheimer equation for solids with arbitrary dispersion relations and examined its predictions for graphite, finding that the isotropic equation vastly overestimates the boundary scattering that occurs in thin graphite films due to the highly anisotropic group velocity, and that graphite can maintain its high in-plane thermal conductivity even in thin films with thicknesses as small as 10nm.

TL;DR: In this article, the authors examined how thermal resistance depends on the heater geometry using analytical solutions of the Boltzmann equation, and showed that the spatial frequencies of the heater pattern play the key role in setting the thermal resistance rather than any single geometric parameter, and that for many geometries the thermal sensitivity in the quasiballistic regime is no different than the Fourier prediction.
