Controlling ice formation
(PHYSorg.com Nanotechnology)

(Phys.org)-Researchers have demonstrated that ice crystals will grow along straight lines in a controlled way on microgrooved surfaces. Compared to the random formation of ice crystals on smooth surfaces, the ice on the microgrooved surfaces forms more slowly and melts more quickly, which could lead to improved anti-icing and deicing methods. Ice formation is currently a major problem in a wide variety of areas, including solar panels, refrigeration systems, power transmission systems, and aircraft, and the new surface may help reduce ice build-up in these systems.
