Herein we propose a novel approach to the preparation of quasi-1D nanostructures with various chemical compositions based on infiltration of colloidal solution into the asymmetric anodic alumina membrane. The proposed technique was successfully applied for the preparation of ordered arrays of the magnetically hard anisotropic hexaferrite nanostructures.

formation of a fluorescent-dye layer on the surface of porous alumina, the porous alumina substrate was dipped in an ethanol solution containing 20 wt.-% dendrimer [13] and 4 × 10 M pyrromethene 597 (EXITON) for 1 min and then dried. The thickness of the fluorescent-dye layer was approximately 1 lm. Optically pumped lasing experiments were performed using a frequency doubled Nd:yttrium aluminum...

A strong solid/liquid interfacial interaction is found between porous alumina and graphene oxide (GO) aqueous dispersion, which promotes a fast enrichment of GO on the alumina surface and results in the formation of a GO hydrogel.

Porous alumina templates are fabricated by anodization of Al in an acid. The characteristics of the template, such as the pore diameter, interpore separation, and the periodicity of the porous structure depend on the conditions of anodization and the acid that is used as electrolyte. The variation of pore diameter and interpore separation as a function of anodization parameters are described. T...

Titanium oxide (TiO2) nanowires were prepared for an electrolytic capacitor application by the automatic dipping technique using a porous alumina template. The automatic dipping technique allows us to exactly control the dipping rate so that we can obtain homogenous infiltration of nanowires in the porous alumina membrane, even though the solution is very acidic. From the TEM, SEM and XRD measu...

This thesis is devoted to the study of vertical Pourous Anodic Alumina templates (PAA) and the application thereof for nanoorganization and device fabrication. Our principle objective was to develop an anodization method of Al that allows a reproducible fabrication of PAA offering the possibility to create complex porous nanostructures as well as the organization of nanomaterials. The PAA fabri...
