Altering surface textures in 'counterintuitive manner' may lead to cooling efficiency gains

Researchers across the globe are racing to find ways to improve the cooling of hot surfaces -- for technologies ranging from small electronics to nuclear power plants. Zeroing in on the physics at play underlying surface phenomena, researchers made a significant breakthrough. Although somewhat counterintuitive, they discovered that by creating sparsely packed textures on surfaces rather than densely packed ones, they were able to hold droplets in place and enable cooling.
