Summary: Titanium dioxide nanotubes (TNTs) grown on the surface of titanium implants play a significant role in preventing tissue infection and implant failure. This study investigates the role of different counter electrodes in the formation of TNTs with varying shapes and surface properties. The use of platinum and graphite cathodes results in circular TNTs, while stainless steel cathode leads to hexagonal-shaped tubes with particle debris on the surface. The surface microstructure of TNTs affects their roughness, hydrophilicity, and ability to facilitate the growth of bone-forming apatite during osseointegration.

Summary: Due to the various sample preparation techniques and optical measurement strategies, there are different experimental datasets available for the complex dielectric function of gold. Evaluating and selecting the most reliable datasets is crucial for optical-based designs and applications. The Brendel-Bormann model, known for its accuracy, is used as a criterion, with MS Excel being employed for its calculation. 'Palik' and 'Babar' are found to have the most accurate datasets for the real part of the dielectric function in the short- and long-wavelength ranges, respectively, while the reverse is true for the imaginary part. The validity of these datasets is attributed to using gold samples with minimal structural and surface imperfections.
