It is known that normal graphene is a good conductor of heat, still there are some drawbacks. While heat moves easily across the surface of stacked graphene, it does not easily pass through several layers of the material. Researchers at Rice University made use of 3D variant of this graphene to deal with this problem.

Boron nitrade nanotubes have been used to create these 3D structures of white graphene. These nanotubes help unobstructed heat transfer. The findings of this research will lead to a smaller and better way to control the heat. And this could cool down any highly efficient and smaller electronics device.

As per scientists at Rice University, three-dimensional structures of boron nitride could help in keeping small electronics cool. Rouzbeh Shahsavari and Navid Sakhavand from Rice University have come up with the first hypothetical analysis of use of 3-D boron nitride as a tunable material so as to control heat flow in these kinds of devices.

The work carried out by researchers has been published in the American Chemical Society journal Applied Materials and Interfaces.

According to him, "Typically in all electronics, it is highly desired to get heat out of the system as quickly and efficiently as possible. One of the drawbacks in electronics, especially when you have layered materials on a substrate, is that heat moves very quickly in one direction". However, he added that it doesn't behave in same manner when it comes to movement of heat from layer to layer.
