Abstract:

ZnO nanostructures coated Cu (Copper) have been successfully grown using a method of seed mediated hydrotermal. The growth of Cu coated ZnO nanostructures were used as an active material of DSSC. The Cu on ZnO nanostructures has been coated at a concentration of 10 mM at room temperature in 30 minutes. The samples were characterized using Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX). The FESEM images showed that the geometrical shape of ZnO nanostructures was nanoflower. Spectra of EDX showed Cu was really exist in all samplesof about 0.8%. A DSSC was fabr

Analytical transmission electron microscopy (TEM) and scanning electron microscopy (SEM) have been applied for the characterization of evolution, lateral arrangements, orientations, and the microscopic nature of nanostructures formed during the early stages of ultrahigh vacuum electron beam evaporation of Cu onto surfaces of VSe2layered crystals. Linear nanostructure of relatively large lateral dimension (100–500 nm) and networks of smaller nanostructures (lateral dimension: 15–30 nm; mesh sizes: 500–2000 nm) are subsequently formed on the substrate surfaces.

Gold (Au) and copper (Cu)-based nanostructures are of great interest due to their applicability in various areas including catalysis, sensing and optoelectronics. Nanostructures synthesized by the galvanic displacement method often lead to non-uniform density and poor size distribution. Here, density and size-controlled synthesis of Au and Cu-based nanostructures was made possible by galvanic displacement with limited exposure to hydrofluoric (HF) acid and the use of surfactants like L-cysteine (L-Cys) and cetyltrimethylammonium bromide (CTAB).

Abstract:

The undoped and Cu doped ZnO (Cu: ZnO) nanostructures were successfully synthesized by the chemical bath deposition (CBD) technique to study the influence of copper (Cu) content on its surface morphology, elemental, optical and thermal properties. Powder X-ray diffraction (XRD), Field Emission Scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), ultraviolet-visible (UV-vis) spectroscopy, Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) techniques have been used for different characterization. XRD studies showed hexagonal wurtzite ZnO nan

Abstract:

ZnO nanostructures were electrochemically synthesized on Cu and on chemical vapor deposited (CVD)-graphene/Cu electrodes. The deposition was performed at different electrode potentials ranging from −0.8 to −1.2 V, employing a zinc nitrate bath, and using voltametric and chronoamperometric techniques. The effects of the electrode nature and of the working electrode potential on the structural, morphological, and optical properties of the ZnO structures were investigated. It was found that all the samples crystallize in hexagonal wurtzite structure with a preferential orientation along the c-axi

Background: Flower-shaped micro/nanostructures containing adsorbent and antimicrobial agent within the same particle are a new generation of materials with considerable potential in the field of biomedicine. Objective: Flower-shaped micro/nanostructures were fabricated by the reaction of Al/Cu, Al/Fe and Al/Zn bimetallic nanoparticles with water. Al/Cu, Al/Fe and Al/Zn nanoparticles were produced by the simultaneous electric explosion of a pair of the corresponding metal twisted wires (aluminum and copper, aluminum and iron or aluminum and zinc) in argon atmosphere.

Abstract:

Achieving perfect honeycomb network with large-scale order for molecular systems is technically promising, while remains challenge, where defects and disordering can dramatically affect their performance. The intrinsic topological defects cannot be healed with different preparation parameters owing to the conformational flexibility of the precursor skeleton, which allows the deformation of precursor monomers with limited tension. To address this issue, we adopted a tripod precursor 2,4,6-tris(4-bromophenyl)−1,3,5-triazine (pTBPT), and networks consisting of different membered rings are firstly

We directly observed unique morphological changes in Cu-doped graphene by aberration-corrected TEM. DFT calculations reveal a reduction of energy barrier that caused rotation of C–C bonds near Cu atoms. Our results suggest that individual Cu atoms can catalyse reconstruction of carbon nanostructures.

Abstract:

Brasses are well-known structural materials, and their electrochemistry seems to be known. However, the formation of nanostructured anodic oxides on brasses is still not common and researched enough. Despite the electrochemical oxidation or anodization of copper and zinc being well-recognized and known in the scientific community, there is a lack of a satisfactory amount of research on brass anodizing. Both copper and zinc can passivate in neutral and alkaline electrolytes, and also the mechanism of the nanostructured oxide growth of both seems to be similar. In this review, much effort was pu

In this study, four kinds of phospholipase A1-metal (Al/Co/Cu/Mn) hybrid nanostructures were prepared for enhancing the stability of the free PLA1. The formed hybrid complexes were characterized by scanning electron microscope (SEM), Fourier infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The stability and substrate specificity of immobilized enzymes were subsequently determined. After immobilization, the temperature tolerance of PLA1–metal hybrid nanostructures was enhanced. The relative activity of PLA1–Al/Co/Cu hybrid nanostructures remained above 60% at 50 °C, while that of free
