In a original study recently published in Nature Nanotechnology,researchers from Columbia Engineering, Cornell, or Stanford have demonstrated heat transfer can be made 100 times stronger than has been predicted,simply by bringing two objects extremely close—at nanoscale distances—without touching. Led by Columbia Engineering's Michal Lipson and Stanford Engineering's Shanhui Fan, the team used custom-made ultra-tall precision micro-mechanical displacement controllers to achieve heat transfer using light at the largest magnitude reported to date between two parallel objects.
