Nanoporous Microtubes via Oxidation and Reduction of Cu–Ni Commercial Wires
Metals, 2017 Metallic porous microtubes were obtained from commercial wires (200–250 µm diameter) of Cu-65Ni-2Fe, Cu-44Ni-1Mn and Cu-23Ni, alloys (wt. %) by surface oxidation at 1173 K in air, removal of the unoxidized core by chemical etching, and reduction in ...

Influence of the epitaxial composition on N-face GaN KOH etch kinetics determined by ICP-OES
Beilstein Journal of Nanotechnology, 2020 Roughening by anisotropic etching of N-face gallium nitride is the key aspect in today’s production of blue and white light emitting diodes (LEDs). Both surface area and number of surface angles are increased, facilitating light outcoupling from the LED ...
