A study on the chemical stability of anodic alumina membranes and their performance in long-term water and organic solvent permeation experiments is reported. Anodic alumina possesses high stability for both protonic and aprotonic organic solvents. However, serious degradation of the membrane occurs in pure water, leading to a drastic decrease of permeance (over 20% of the initial value after t...

s in any form of chemical analysis, the quality of information obtained from a depth profiling experiment is only as good as the reference materials that are used to calibrate the instrument. In the case of depth profiling, calibration must take place in terms of chemical composition as well as distribution with respect to the specimen surface. The nature of applications requiring such analyses...

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 ...

In this study, aluminum (Al) film with high purity was coated on the Niobium (Nb) sheet by thermal evaporation under ultra-high vacuum. An Anodic Aluminum Oxide (AAO) nanotemplate prepared Nb sheet. During AAO preparation, three-dimensional (3D) nanopillars were grown We performed a simple 3D Artificial Intelligence (AI) analysis of nanopillars. According to experimental results, width is in ra...

In this figure , the Rayleigh‐instability‐induced transformation of gold nanoparticle/polystyrene (AuNPs©PS) hybrid materials confined in nanopores anodic aluminum oxide (AAO) templates is investigated. Upon thermal annealing, AuNPs©PS nanotubes undergo Rayleigh‐instabilityinduced and four morphologies are obtained. More details about will be discussed by Prof. Jiun‐Tai Chen his co‐workers on p...
