Summary: Anodic alumina membranes with a high degree of porous structure are ideal templates for manufacturing nanostructured materials in optoelectronics, sensors, magnetic memories, and electronic circuits. By adjusting anodizing parameters, the morphology characteristics such as pore length, pore diameter, and cell density can be accurately controlled. The addition of aluminum ions to phosphoric acid-based anodizing solution can significantly affect the morphology of the porous layer in anodic alumina membranes, impacting the overall structure and properties.

Summary: In this study, ordered diamond nanopillar arrays were synthesized through a bottom-up approach using porous anodic aluminium oxide (AAO) templates. Commercial ultrathin AAO membranes were used as the growth template, and a three-step fabrication process involving chemical vapor deposition (CVD) was employed. After removing the AAO template, ordered arrays of submicron and nanoscale diamond pillars with diameters of around 325 nm and 85 nm, respectively, were successfully released.

Summary: This paper introduces a method for producing mesoporous metals with periodic 3D nanostructures by tuning the nanoscale dimensions of the metal through the addition of a cosurfactant that controls the lattice parameter of the template. Characterization of mesoporous platinum samples using X-ray scattering revealed varying unit cell sizes, wire thicknesses, and estimated pore dimensions. The control of size in these materials offers potential for controlling electrochemical behavior and designing metamaterials with specific optoelectronic properties.

Summary: We investigated the structural evolution of electrochemically fabricated Pd nanowires in situ using various techniques. Our study demonstrated the formation of beta-phase Pd hydride during the bottom-up growth of the nanowires and its phase transition to alpha-phase Pd after electrodeposition was suspended. We also found that grain coalescence hindered the incorporation of hydrogen in the Pd unit cell.
