Heat conduction originates from both particle-like diffusion of phonon wave-packets (blurred spheres, following the realistic 3D phonon dispersion of CsPbBr3) and wave-like tunneling (blue waves).

How heat travels, matters. Yet, there is still no consensus on the exact physical mechanism that causes anomalous heat conduction -- despite the existence of previous numerical simulation, theoretical ...

Unlike classical heat diffusion at macroscale, nanoscale heat conduction can occur without energy dissipation because phonons can ballistically travel in straight lines for hundreds of nanometres.

Engineers at Cornell University have developed perforated, flexible panels modeled on fish gills that significantly improve ...

Heat and mass ransfer by heat conduction, diffusion, and convection. (Linear phenomena only; heat transfer by radiation, natural convection, and mass transfer in concentrated solutions are not ...

Prof. Gal Shmuel of the Faculty of Mechanical Engineering at the Technion—Israel Institute of Technology has developed an innovative approach that enables precise control of heat conduction in ways ...

New work could help design electronic devices in which heat can be guided in certain directions, minimizing heat loss ...
