2D ZnO nanostructure-based biosensors: synthesis, classification, types and applications.
A Raman scattering enhancement factor up to 4.2 normalized with pure silicon has been achieved by applying the electron beam lithography (EBL) technique to build silicon nanostructure array. Several mechanisms are adopted to explain and discuss the enhancement phenomenon . Through the improvement on the adjustability, uniformity, and stability of the structures, it is expected that a more robus...
Amyloid fibrils belong to the group of ordered nanostructures that are self-assembled from a wide range of polypeptides/proteins. Amyloids are highly rigid structures possessing a high mechanical strength. Although amyloids have been implicated in the pathogenesis of several human diseases, growing evidence indicates that amyloids may also perform native functions in host organisms. Discovery o...
This article provides a comprehensive review of the current research activities that focus on the ZnO nanostructure materials and their physical property characterizations. It begins with the synthetic methods that have been exploited to grow ZnO nanostructures. A range of remarkable characteristics are then presented, organized into sections describing the mechanical, electrical, optical, magn...

High-pressure torsion (HPT) and thermal annealing were applied to a face-centered cubic as-cast Al0.3CoCrFeNi high entropy alloy. Processing by HPT produced a nanostructure with a higher incremental hardness than in most HPT single-phase materials and subsequent annealing at appropriate temperatures gave an ordered body-centered cubic secondary phase with an additional increase in hardness. The...
