Abstract In the study of plastic flow and mechanical features zinc subjected to severe deformation at low temperature through KOBO extrusion method, three techniques micro nanostructure identification have been used (TEM, STEM, HAADF). It was shown that pattern long trails—a typical element microstructure after deformation, results from strain fields densely spaced nano-dimensional clusters poi...

This paper describes the fabrication of polymer stamps using DNA nanostructure templates. This process creates stamps having diverse nanoscale features with dimensions ranging from several tens of nanometers to micrometers. DNA nanostructures including DNA nanotubes, stretched λ-DNA, two-dimensional (2D) DNA brick crystals with three-dimensional (3D) features, hexagonal DNA 2D arrays, and trian...

Nickel oxide (NiO) nanopowder was obtained during a sonochemical method. Nickel hydroxide precursor, prepared by addition of sodium hydroxide (NaOH) to nickel nitrate Ni(NO3)2 solution and vigorously stirring until the pH becomes 7.2. Ultrasounds waves were applied during precipitation period and after drying in oven nanopowder NiO was achieved. Transient and scanning electron microscopy showed...

We show that the coherence of charge transfer through a weakly coupled double-dot dimer can be determined by analyzing the statistics of the conductance pattern, and does not require a large phase coherence length in the host material. We present an experimental study of the charge transport through a small Si nanostructure, which contains two quantum dots. The transport through the dimer is sh...

wileyonlinelibrary.com internal/external surface sites of the nanostructure. Thus, the big challenge is in the nanostructure architecture where all of these parameters need to be optimized simultaneously. For the case of a supercapacitor, the nanostructure material is used as the framework to store and transport charges between two parallel electrodes. A conventional supercapacitor usually cons...

a straightforward approach for the extraction of the quercetin was carried out by a nanoporous molecularly imprinted acrylic acid-based network copolymer as asolid sorbent. this technique involves a molecular template (quercetin) which is surrounded by functional monomers and are subsequently co-polymerized in the presence of an excess of the cross linkers. in this process, three-dimensional bi...

Background: Au nanoparticles (AuNPs) exhibit very unique physiochemical and optical properties, which now are extensively studied in a range of medical diagnostic and therapeutic applications. AuNPs can be used for cancer clinical treatment with minimal invasion. On the other hand, curcumin is a polyphenol derived from turmeric which is used for medical purposes due to its anti...

In this study, we report formation of weblike fibrous nanostructure and nanoparticles of magnetic neodymium-iron-boron (NdFeB) via femtosecond laser radiation at MHz pulse repetition frequency in air at atmospheric pressure. Scanning electron microscopy (SEM) analysis revealed that the nanostructure is formed due to aggregation of polycrystalline nanoparticles of the respective constituent mate...

Distinct electromagnetic properties can emerge from the three-dimensional (3D) configuration of a plasmonic nanostructure. Furthermore, the reconfiguration of a dynamic plasmonic nanostructure, driven by physical or chemical stimuli, may generate a tailored plasmonic response. In this work, we constructed a 3D reconfigurable plasmonic nanostructure with controllable, reversible conformational t...

Dendrite-like Co(3)O(4) nanostructure, made up of many nanorods with diameters of 15-20 nm and lengths of 2-3 μm, has been successfully prepared by calcining the corresponding nanostructured Co-8-hydroxyquinoline coordination precursor in air. The Co(3)O(4) nanostructure was evaluated as an electrochemical sensor for H(2)O(2) detection and the results reveal that it has good linear dependence a...
