“…If the electro-deposition process is not stopped at this stage, the current keeps on rising very gradually leading to over-deposition of copper. The exotic patterns in the form of micro-flowers having their petals in nanometer dimension, copper buds leading to mushroom effect and double pyramid-shaped copper crystals have been observed in our investigations [25][26][27][28][29][30]. It has also been reported by National Institute of Technology (NIT), Kurukshetra [55] that over-deposition of copper in polymer templates may lead to formation of metallic micro-rose having petals in nanometer dimensions [Fig.…”

“…Electro-deposition technique used in our experiments [25][26][27][28][29][30] is similar in principle to that used for the electroplating process and has been vividly described in the Chapter on Nanowires. Commercially available polycarbonate membranes (Sterlitech, USA) of 25 mm diameter with pore density of 10 8 pores/ cm 2 and pore diameter of 100 nm were selected for this experiment.…”

A wide variety of metallic and metal oxide nanoflowers and other exotic patterns have been fabricated using different techniques. We have created copper and cupric oxide nanoflowers using two different techniques: electro-deposition of copper in polymer and anodic alumina templates, and cytyltrimethal ammonium bromide (CTAB)-assisted hydrothermal method, respectively. Zinc oxide and manganese oxide nanoflowers have been synthesized by thermal treatment. Characterization of nanoflowers is done in the same way as for nanowires using XRD, SEM, TEM and FESEM. Scanning Electron Microscope (SEM) images record some interesting morphologies of metallic copper nanoflowers. Field Emission Scanning Electron Microscope (FESEM) has been used to determine morphology and composition of copper oxide nanoflowers. X-ray diffraction (XRD) pattern reveals the monoclinic phase of CuO in the crystallographic structure of copper oxide nanoflowers. Nanoflowers find interesting applications in industry. There is an element of random artistic design of nature, rather than science, in exotic patterns of nanoflowers fabricated in our laboratory.

“…The metal surface after the anodization process converted to a thick and hard oxide layer, which provides some degree of corrosion protection for the underlying metal. Recently Nano copper oxide coating is being developed for various applications as, gas detection sensors, superhydrophobic surfaces, specialized solar cells [1,2,3]. Other researchers study the increasing of the surface hardness and the corrosion resistance of metals by anodization process [4,5].…”

Abstract. The metals anodization process used to enhance the surface hardness and corrosion resistance. This study developed a durable hard Nano copper oxide coating on copper using anodization technique in solutions of 0.1 to 0.5 M oxalate concentrations and 0 to 24 ο C operating temperature. The settings of the process parameters determined by using Taguchi's experimental design method. The EDX and XRD results confirm the formation of cupric oxide coating with monoclinic lattice crystalline structures. The FESEM results for the coated samples showed that the grain size was in the range between 25 to 68 nm. Microhardness tests for the anodized copper samples characterized by microhardness tester. Analysis of Variance for the orthogonal arrays of Taguchi identified that the most affecting parameter on the microhardness of the coating was the anodizing temperature. The results show that the hardness of the anodized coating was decreased with the anodizing temperature, where maximum hardness, with smaller grain size, were produced at lower anodizing temperatures.

“…One-dimensional nanowires (NWs) have attracted considerable attention in recent years [5][6][7][8][9] because of their novel physical properties and potential applications as interconnects in nanometrescale electronics. The progress in this field has been accelerated by advances in both synthetic methods of preparing the nanoporous templates, and development of techniques capable of filling the pores of such membranes.…”

One-dimensional nanowires (NWs) have attracted considerable attention in recent years because of their novel physical properties and potential applications as interconnects in nanometre-scale electronics. NWs have potential applications in nanoscale electronics, optoelectronics, photonics, sensors, and solar cells due to their unique electrical, chemical, and optical properties. Several chemical and physical methods are commonly used to produce NWs. Among them, electrochemical synthesis and vapour-liquid-solid (VLS) methods to produce NWs have become popular among scientific workers due to a number of advantages. Synthesis of NWs using anodic alumina and polymer templates in an electrochemical cell has been described in detail as investigated in our laboratory. Characterization of metal and semiconductor NWs has been accomplished using scanning electron microscope (SEM), field emission scanning electron microscope (FESEM), high resolution transmission microscope (HRTEM), X-ray diffraction (XRD), and energy dispersive X-ray analysis (EDAX). Morphology of NWs has been revealed by SEM, structure by TEM, crystallinity by XRD and chemical composition by EDAX. I-V characteristics of copper and semiconductor NWs were recorded in-situ, as grown in pores of anodic alumina template, using Dual Source Meter (Keithley Model 4200 SCS) with platinum probes for contacts. Resonating tunneling diode (RTD) characteristics of fabricated NWs have been investigated. Bulk production of Copper NWs has been described by seed growth technique. Applications of NWs are not covered in any detail under this review. Table of Contents
