Layer-by-Layer Self-Assembly Marine Antifouling Coating of Phenol Absorbed by Polyvinylpyrrolidone Anchored on Stainless Steel Surfaces

Journal of Marine Science and Engineering
Marine biofouling is a major problem that contributes to the failure of man-made marine structures. Conventional marine antifouling coatings that release heavy metal ions for antimicrobial purposes are no longer in line with today’s environmental issues.

Time-dependent universal conductance fluctuations in mesoscopic Au wires: implications

, 2007
In cold, mesoscopic conductors, two-level fluctuators lead to time-dependent universal conductance fluctuations (TDUCF) manifested as $1/f$ noise. In Au nanowires, we measure the magnetic field dependence of TDUCF, weak localization (WL), and magnetic ...
