A nanostructure composed of Anodic Aluminum Oxide (AAO) was obtained on an electrode of a quartz crystal microbalance (QCM) chip by anodizing Al thin film in an oxalic acid solution. The effective surface area was expanded by these nanostructures. Several morphologies were observed under various anodic conditions by using scanning electron microscopy (SEM). We demonstrated that a QCM chip with ...

The melt memory effect is well-known in polymer crystallization. It caused by self-nuclei that persist above the melting temperature. origin and physical nature of are still under debate. In this work, we studied confinement on self-nucleation (SN) behavior two typical semicrystalline polymers, poly(ε-caprolactone) (PCL) poly(butylene succinate) (PBS), using anodic aluminum oxide (AAO) template...

Polymers occupy a central role in current society due to their utility and versatile properties. As part of the class soft materials, polymers have also been employed research through nanostructuration functionalization, looking for development new metamaterials with wide applicability science society. A particular polymer, Polyethylene, has widely used both commodities, ways nanostructure impr...

Wet-chemical etching of the barrier oxide layer of anodic aluminum oxide (AAO) was systematically investigated by using scanning electron microscopy (SEM), secondary ion mass spectrometry (SIMS), and a newly devised experimental setup that allows accurate in situ determination of the pore opening point during chemical etching of the barrier oxide layer. We found that opening of the barrier oxid...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...

Highly ordered nanoporous anodic aluminum oxide (AAO) thin films were fabricated in oxalic acid under a constant voltage via a two-step anodization process. To investigate the high-aspect-ratio (7.5:1) filling process, both sputtering and atomic layer deposition (ALD) were used to form TiO2 nanowires. Field emission scanning electron microscopy and high-resolution transmission electron microsco...

A dense inner layer is highly valued among the surface coatings created through plasma electrolytic oxidation (PEO) treatment, because the PEO coating has been troubled by inherent porosity since its conception. To produce the favored structure, a proven technique is to prompt a soft sparking transition, which involves a sudden decrease in light and acoustic emissions, and a drop in anodic volt...

A capillary-enforced template-based method has been applied to fabricate calcium copper titanate (CaCu3Ti4O12, CCTO) nanotubes (diameter ~200 nm) by filling sol-gel CCTO precursor solution into the nanochannels of porous anodic aluminum oxide (AAO) templates, subsequent heating for phase formation and finally the removal of nano-channel templates by applying basic solution. X-ray diffraction (X...
