Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse ...

Different materials are used for fabrication of biosensors based on their applications and other considerations as sample type and cost, among others. Biosensors can be miniaturized since microscale devices offer several ...

The present work reports the porous alumina structures fabrication and their quantitative structural characteristics study based on mathematical morphology analysis by using the SEM images. The algorithm used in this work ...

This a study on the achievement of alumina membranes by the method of anodizing. From this method got up a layer of aluminum oxide on the anodic metal, who presented the basic properties necessary for the application as a ...

In this study, the wettability of porous anodic alumina (PAA) surfaces modified by plasma was investigated. The porous anodic alumina films were grown on aluminum substrate using a two step anodization procedure in oxalic ...

This work covers the investigation and synthesis of nanometric structures of Porous Anodic Alumina PAA, produced from low purity substrates, in aim to obtain selfsustained membranes. The Hard Anodization (HA) and Mild ...

In this project we studied the porous anodic alumina as a possible application in gas sensors with high sensitivity. Initially we seek a configuration of anodic porous alumina (PA) and the type of gas or vapor in which ...

Porous anodic alumina (PAA) has been used as platform for the manufacture of optical sensors. Itshows chemical resistance, thermal stability, hardness, biocompatibility, high surface area which facilitates interaction with ...

We present in this paper an active waveguide effect observed in porous anodic alumina (PA), which can be applied in optical sensors. The spectral position, shape, and polarization effect of the narrow waveguide modes is ...
