'Heat highways' could keep electronics cool

As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now, as reported in ACS Applied Nano Materials, researchers have used an electrospinning approach to produce a new nanocomposite film. In tests, the film dissipated heat four times more efficiently than similar materials, showing that it could one day be used to keep electronics cool.
