A novel method to quantitatively analyze the domain reversal behavior has been adopted to understand the total-thickness-dependent domain reversal behavior in Co/Pd multilayers. The wall-motion speed and the nucleation rate were simultaneously determined by analyzing serial domain images observed using a real-time domain observation system. Using this method, sensitive decrement of the wall-mot...

AlN nanolayers in sputter deposited {111}Al/AlN/TiN multilayers exhibit the metastable zinc-blende-structure (z-AlN). Based on density function theory calculations, the growth of the z-AlN is ascribed to the kinetically and energetically favored nitridation of the deposited aluminium layer. In situ nanoindentation of the as-deposited {111}Al/AlN/TiN multilayers in a high-resolution transmission...

Abstract Numerous carrier scatterers, such as atomic defects, fixed oxide charges, impurities, chemical residues, and undesired surface adsorbates, including oxygen water molecules, strongly degrade the mobility of atomically thin two-dimensional (2D) materials. However, effect adsorbates oxidation on density profile along thickness 2D multilayers is not well known, particularly for a substanti...

Although metallic multilayers have recently attracted much attention, especially since the discovery of giant magnetoresistance in Fe /Cr multilayers [1], only a small number of true superlattice effects have been experimentally observed. These are the appearance of superlattice Bragg peaks in X-ray diffraction [2], the collective behavior of magnons in magnetic/non-magnetic superlattices [3], ...

Ag-implanted titanium with a nanostructured surface was prepared by hydrothermal treatment with H(2)O(2) followed by Ag plasma immersion ion implantation. Streptococcus mutans, Porphyromonas gingivalis and Candida albicans were chosen for antimicrobial tests. Genes related to microbial structure or adhesion, namely glucan-binding proteins B (GbpB), fimbria protein A (FimA), and agglutinin-like ...

Thermoelectrics have long been recognized as a potentially transformative energy conversion technology due to their ability to convert heat directly into electricity. Despite this potential, thermoelectric devices are not in common use because of their low efficiency, and today they are only used in niche markets where reliability and simplicity are more important than performance. However, the...

Here we detail high performance, enzymatic electrodes for oxygen bio-electroreduction, which can be easily and reproducibly fabricated with industry-scale throughput. Planar and nanostructured electrodes were built on biocompatible, flexible polymer sheets, while nanoimprint lithography was used for electrode nanostructuring. To the best of our knowledge, this is one of the first reports concer...

In the body, vascular cells continuously interact with tissues that possess nanostructured surface features due to the presence of proteins (such as collagen and elastin) embedded in the vascular wall. Despite this fact, vascular stents intended to restore blood flow do not have nanoscale surface features but rather are smooth at the nanoscale. As the first step towards creating the next genera...

Nanometer period metallic multilayers are ideal structures to investigate electronic phenomena at interfaces between metal films since interfacial atoms comprise a large atomic fraction of the samples. The multilayers studied were fabricated by magnetron sputtering and consist of bilayers from 1.9 nm to 3.3 nm. X-ray diffraction, cross-section TEM and plan-view TEM show the Cu layers to have a ...

Circularly polarized light is incident on a nanostructured chiral meta-surface. In the nanostructured unit cells whose chirality matches that of light, superchiral light is forming and strong optical second harmonic generation can be observed.
