Blog Keeping cool during extreme heat To fix a cooling problem in for example electronic devices, we have experimented with a carpet of nano-wires. Guess what, it works. Blog Removing sticky droplets and making super repellent surfaces Super-repellent surfaces lose their repellent properties when condensation occurs, either under low temperatures or high humidity conditions. A new surface has been developed, combining pyramidal microstructures with a nano-sized roughness on top, that maintains its super-repellent properties at all conditions.
