Dr Bartłomiej Graczykowski, a scientist of the Adam Mickiewicz University in Poznań, constructs nanostructures in which sound and heat flow in a strictly controlled manner. The structures can be used for the rapid transmission of huge amounts of information or for the direct conversion of heat into electricity. The research results were published in two prestigious journals: Nano Letters and Nano Energy.

The publication in Nano Letters concerns the control of sound flow in nanostructures and new possibilities in the field of filtering acoustic waves. In the article published in the Nano Energy the scientist describes a heat diode – a device that transfers more heat to one side than to the other.

– This device is made entirely of silicon and can be integrated with everyday electronics. It can be used for the effective removal of process heat, passive cooling or for the construction of thermal valves, – says Dr Graczykowski.
