University of Rochester researchers have discovered and demonstrated the power of tiny patterns, especially when etched by massively powerful lasers. The nano scale patterns have in this case been put to use producing darkness as well as attracting and repelling water. Patterns that produce the strangest and most spectacular side-effects.
The process developed by Chunlei Guo and his team requires no coating or special treatment of the surface, just put the metal in front of the Femto laser and fire away. The lasers extremely fast and intense bursts alter the metal itself, creating micro and nano sized patterns of structures deep into the metal.
