A two-step high field anodization and a controllable barrier layer removing process have been used for the fabrication of porous anodic alumina (PAA) with different morphologies. Based on the PAAs, porous noble metal films with widely tunable pore size and inter-pore distance have been realized by a simple sputtering method. Their morphology and optical properties were studied with a field-emis...

Two-step electrochemical anodization was used for obtaining matrices based on porous anodic alumina (MPAA). Three series of experimental samples were made: 1 – PAAM with thickness 1.3–2.5 μm and 70 nm diameter, 2 70.0 50–75 diameter 3 13.5–60.0 100–200 diameter. The pore filling MPAA realized using deposition. As a result Ni nanopillars, multilayered Cu/CoNi nanowires formed. scanning electron ...

The effect in the Fabry-Pérot optical interferences of nanoporous anodic alumina films coated with gold is studied as a function of the porosity and of the gold thickness by means of reflectance spectroscopy. Samples with porosities between 14 and 70% and gold thicknesses (10 and 20 nm) were considered. The sputtering of gold on the nanoporous anodic alumina (NAA) films results in an increase o...

Abstract We obtained monodisperse albumin particles by membrane emulsification using ordered anodic porous alumina with uniform-sized holes. The particle size could be controlled adjusting the hole in linear relationship between of and hole. loaded a fluorescent dye into adding it to dispersed phase used for emulsification. These have potential use various applications, particular, as drug carr...
