Fabrication of nanoporous alumina by two-step anodization and studyof their structural properties
Bibliographic record
Abstract
Anodic nanoporous alumina (NPA) is known to be a low cost material suitable for fabrication of templates for the growth of a variety of nanostructured materials, membranes and sensors. In this work, nanoporous alumina was prepared in 0.4 M oxalic acid by a two-step anodization process. The properties of nanoporous alumina film grown on aluminum foil were studied by atomic force microscopy (AFM), scanning electron microscopy (SEM) and optical microscopy. The microscopy investigations confirm the pore formation in the produced layers and the process of anodization allows consistent fabrication of nanoporous alumina. The effect of anodization process parameters on the size of the nanopores and the distance between them were studied and good agreement with published data was found. Hence a desired diameter of the pores and the distance between of it can be obtained by adjusting the electrolyte and oxidation voltage.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
