Template electrosynthesis of La(OH)3 and Nd(OH)3 nanowires using porous anodic alumina membranes

Electrostatic capacitance of TiO2 nanowires in a porous alumina template

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...

Fabrication of a porous anodic alumina membrane

With the aim of developing a process for surface enlargement on an electrode for measuring brain activity attempts have been made to fabricate a porous anodic alumina membrane directly on the electrode. The porous membrane was intended to be used as scaffold for deposition of an electrically conducting polymer on the electrode surface. A silicon wafer with gold electrodes was the base onto whic...

Fabrication of nanowires and nanotubes by anodic alumina template-assisted electrodeposition

Cylindrical Three-Dimensional Porous Anodic Alumina Networks

The synthesis of a conformal three-dimensional nanostructure based on porous anodic alumina with transversal nanopores on wires is herein presented. The resulting three-dimensional network exhibits the same nanostructure as that obtained on planar geometries, but with a macroscopic cylindrical geometry. The morphological analysis of the nanostructure revealed the effects of the initial defects ...

An integrated single photon detector array using porous anodic alumina

This paper outlines a single photon sensitive detector array. The detector structure is made via CMOS compatible wafer-scale post-processing. The total system comprises a CMOS imaging chip with charge sensitive pixels, an electron multiplier and a photo-cathode. The electron multiplication is achieved by operating a thick layer of integrated porous anodic alumina as an MCP. Material and geometr...
