Embodiments of the present invention are directed to a surface modified metal piece comprising a first major surface, wherein at least one portion of the first major surface: comprises the reaction product of a surface modifier; has a random micro- and nanoscale structure; and has at least one of a water contact angle when exposed to water of at least about 120° and a spectral reflectance of less than about 25% within the visible spectrum. Other embodiments relate to processes and methods for making such a surface modified metal piece.

Laser-based high-throughput surface nano-structuring (NHSN) process

The disclosure relates to maskless, laser-assisted methods for making a metal surface comprising at least one of hydrophobic and hydrophilic regions; and at least one of micro- and nanostructured regions.
