Abstract
  Zinc oxide nanoparticles (ZnO NPs), copper oxide nanoparticles (CuO NPs) and CuO@ZnO NPs as a colloidal core-shell solution were synthesized by laser ablation. A Nd:YAG laser with an energy of 700 mJ, a wavelength of 1064 nm and 200 pulses was used for the ablation process. The colloidal solution was ...  Read More ...

Abstract
  Photoelectrochemical etching (PECE) was used to prepare porous silicon (PS) layers of polished surfaces of (100) n-type silicon wafers with a resistance of 0.1-100 μm and thickness of 600 ± 25 μm. The directed slices are to be catalyzed at different etching times (5, 15, 25 min) with a constant ...  Read More ...
