Article Synopsis
  • Titanium and its alloys, commonly used in medical devices, struggle with biocompatibility, prompting investigation into improving this feature.
  • The study innovatively employed TiO nanotubes on titanium surfaces, followed by layering polyacrylic acid and gentamicin, with zinc ions added for enhanced bioactivities.
  • Results showed improved blood compatibility and cytocompatibility for endothelial cells, alongside effective antibacterial properties from the combined treatment over a 14-day release period.

In the angular-spectrum method-based computer-generated hologram, the zero-padding method is used to convert circular convolution into linear convolution. However, it will increase the calculation time and memory usage significantly. Therefore, a fast and simple method is proposed to solve the issue of the numerical convolution in the process of hologram generation by using the intermediate angular-spectrum method in this paper.
