Scientists have uncovered a fascinating behavior of heat in an ultra-thin material known as NCCN. This material, which is essentially a single-layer sheet, exhibits exceptional heat conductivity, particularly at room temperature, with a remarkable rate of around 1800 W/mK. However, the intriguing part is that this conductivity doesn't decrease as the temperature rises, defying the typical behavior observed in most materials.

The unusual heat movement in NCCN can be attributed to a phenomenon called phonon hydrodynamics. Essentially, tiny sound waves within the material carry heat, and in NCCN, these waves behave like a fluid. This unique behavior allows heat to move swiftly even at higher temperatures, setting it apart from other materials like graphene.

Interestingly, the way heat moves in NCCN is also influenced by the material's shape. Stretching the material can slow down some of the sound waves, which in turn reduces the efficiency of heat movement. This sensitivity to physical changes highlights the complex nature of heat conduction in NCCN.

This discovery holds significant potential for various applications. Understanding how to control heat in ultra-thin materials could lead to advancements in cooling technologies for electronics and other devices. Moreover, NCCN's superior performance at higher temperatures suggests it might outperform graphene in certain applications.
