Abstract: A method, device and system are disclosed including a substrate, a computational device mounted on the substrate, and a heat dissipator thermally coupled to the device. In some embodiments, at least one surface of the computational device has a nanostructure ceramic layer formed upon. In some embodiments, the nanostructure ceramic layer includes at least one of Al2O3, Si3N4, and BeO. In some embodiments, the at least one surface is on the substrate. In some embodiments, the at least one surface is on the heat dissipator. In some embodiments, the nanostructure ceramic layer includes at least one nanostructure with a diameter in the range of 10-5,000 nm. In some embodiments, the nanostructure ceramic layer may be a repeating pattern of nanostructured elements having uniform sizes and shapes. In some embodiments, the nanostructure ceramic layer is a random pattern of nanostructured elements having non-uniform sizes and shapes
