Tunable Nanoporous Anodic Alumina Photonic Crystals by Gaussian Pulse Anodization

ACS Applied Materials & Interfaces, 2020
This study presents a Gaussian pulse anodization approach to generate nanoporous photonic crystals with highly tunable and controllable optical properties across the visible-NIR spectrum. Nanoporous anodic alumina Gaussian photonic crystals (NAA-GPCs) are fabricated in oxalic acid electrolyte by Gaussian pulse anodization, a novel form of pulse-like ...

Polishing methods for formation nanoporous anodized alumina

2023
In the manufacture of the porous anodic aluminum oxide (PAAO) matrix, its quality and structural perfection primarily depend on the quality of the surface. The technological scheme for obtaining highly organized porous aluminum oxide includes preliminary preparation of the foil surface of A9 alloy with an aluminum content of 99.91% by electrolytic ...

Photoluminescent Enzymatic Sensor Based on Nanoporous Anodic Alumina

ACS Applied Materials & Interfaces, 2012
Herein, we present a smart enzymatic sensor based on nanoporous anodic alumina (NAA) and its photoluminescence (PL) in the UV-visible range. The as-produced structure of NAA is functionalized and activated in order to perform the enzyme immobilization in a controlled manner.

Ionic transport across tailored nanoporous anodic alumina membranes

Journal of Colloid and Interface Science, 2012
Highly ordered Nanoporous Alumina Membranes (NPAMs) with a precise control of the pore size and different porosity but thickness around 63 μm were fabricated by the two-step anodization process using different acidic aqueous solutions, oxalic (Al-Ox), sulfuric (Al-Sf), and phosphoric (Al-Ph) acids, respectively. The pore size was controlled by properly

Characterization of nanopores ordering in anodic alumina

Thin Solid Films, 2008
A simple characterization method of the ordering of the nanopores is described for nanoporous anodized aluminium oxides. The method starts with image analysis on scanning electron microscopy representations for the purpose to find repetitive shapes and their centres, i.e. nanopores. Then triangles defined by coordinates of the centres are identified by
