Nanoporous Anodic Alumina for Optofluidic Applications
2015The dynamics of liquid imbibition in nanoporous anodic alumina (NAA) has been recently studied by using the integration of optics and microfluidics. Here the latest results on the subject are revised, and some perspectives for using NAA in optofluidics applications are considered, notably the characterization of the membranes itself.

Effect of Etching on Nanoporous Anodic Alumina
Iranian Journal of Science and Technology, Transactions A: Science, 2019Nanoporous anodic alumina were fabricated by using aqueous oxalic acid electrolyte via the simple and convenient electrochemical anodization method. The pore formation resulted from the interaction of surface aluminum with the prepared electrolyte of 0.3M oxalic acid having pH value less than 5.

The Incorporation of Carbon Element into Nanoporous Anodic Alumina by Pulse Anodization
Journal of Nanoscience and Nanotechnology, 2019The incorporation of carbon element into nanoporous anodic aluminum oxides from oxalic acid electrolyte was studied. The carbon element content in nanoporous anodic alumina by pulse anodization reaches up to ∼20 at.%, while it remains ∼7 at.% under constant anodization. It was proposed that the ionic dynamics in nanopores governs the carbon-containing

Lasing in dye-infiltrated nanoporous anodic alumina membranes
Applied Physics B, 2018Laser emission is obtained from a slab of nanoporous anodic alumina on an aluminum sheet, infiltrated by rhodamine 6G dye in methanol and pumped by 532 nm, 700 ps laser pulses. The nanostructured surface maintains a continuous flow of the dye solution by wetting and evaporation of methanol.

Titanium dioxide-coated nanoporous anodic alumina optical properties
Applied Surface Science, 2019Abstract Ordered nanoporous anodic alumina (NAA) samples are fabricated by the two-step anodization process. The surface of NAA is modified by means of the spray pyrolysis of titanium dioxide (TiO2). The morphology and optical properties of the samples are investigated. UV–Vis-NIR reflectance of NAA and NAA coated with TiO2 has been both measured and
