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.

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 ...

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 ...

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research.

In this section, we first provide an overview of hyperthermia modeling, including the key nanoparticle, excitation source and tissue properties studied. Next, we use two recently published models of ...

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