MIT Cracks Nanoscale Heat Transfer Calculations
MIT researchers derived a formula that can determine the maximum heat transfer between two objects that are less than eight microns (10-6 m) apart, even on the nanoscale. MIT reports that as long as the material of the objects and the distance between them is known, the formula can calculate the maximum heat that can be passed between these objects.
This simple equation can be applied to various shapes. With only the distance between the objects and a material constant that depicts the amount of electric current the object can build up, they are able to characterize the heat transfer.
