Posted: 04 Nov 2015 10:32 AM PST Materials that actively repel water and ice very strongly are sought after by the aviation industry and for many other technical applications. Researchers have now found out how to specifically design the rigid surfaces of such materials: by teaching water droplets how to trampoline. |

Since then, heat-sensing devices have found many real-word applications but have remained relatively expensive and rigid. But a new development featuring graphene could lead to a flexible, transparent and low-cost infrared vision system. |
