Book Description :

The scopes of this research work are divided into four main parts. The work scope in this research begins with the design of the Interdigitated electrode (IDE). The mask will be designed by using AutoCAD software and the size of the mask must be in 100 nm. In the second scope, the fabrication and optimization of the Zinc Oxide nanowire based sensor is conducted though deposition of zinc oxide by using spin coating on the IDE electrode and etching method with suitable parameters. Intially, the zinc oxide wire is deposited and the nano wires are then grown vertically on the ZnO wire surface simultaneously. Next, the third scope, morphological characterize of the Zinc Oxide nanowire is conducted by using scanning electron microscopy (SEM), atomic force microscopy (AFM), and high power microscopy (HPM) to ensure that the nanowire is grown is in correct orientation. Electrical characterization on the fabricated zinc oxide nanowire biosensor is conducted by current-voltage test, and resistivity test. This is to validate the electrical performances of the zinc oxide nanowire biosensor. Finally, validation of the fabricated zinc oxide nanowire biosensor performances on DNA binding is conducted via electrical measurement by using Semiconductor parametric analyzer (SPA) and IV-CV method. The selectivity and sensitivity of the biosensor device is also examined.

Book Description :

Nanostructured Anodic Metal Oxides: Synthesis and Applications reviews the current status of fabrication strategies that have been successfully developed to generate nanoporous, nanotubular and nanofibrous anodic oxides on a range of metals. The most recent achievements and innovative strategies for the synthesis of nanoporous aluminum oxide and nanotubular titanium oxide are discussed. However, a special emphasis is placed on the possibility of fabrication of nanostructured oxide layers with different morphologies on other metals, including aluminum titanium, tantalum, tin, zinc, zirconium and copper. In addition, emerging biomedical applications of synthesized materials are discussed in detail. During the past decade, great progress has been made both in the preparation and characterization of various nanomaterials and their functional applications. The anodization of metals has proven to be reliable for the synthesis of nanoporous, nanotubular and nanofibrous metal oxides to produce a desired diameter, density, aspect ratio (length to diameter) of pores/tubes, and internal pore/tube structure.

Book Description :

The main objective of this communication is to report the synthesis and characterization of zinc oxide (ZnO) based nanostructures and composites for energy related applications using a simple and cost-effective chemical bath deposition (CBD) technique. Highly crystalline zinc oxide (ZnO) nanowires (NWs) were synthesized through CBD method using a simple seeding technique. This seeding process includes dispersion of commercially available ZnO nanoparticles through spraying on a desired substrate prior to the CBD growth. A typical growth period of 16 h produced ZnO NW assemblies with an average diameter of ~45 nm and lengths of 1–1.3 μm, with an optical band gap of ~3.61 eV. The NWs growth was successfully achieved on various substrates (e.g silicon dioxide, plastic sheets, copper grid, and carbon nanotube buckypaper). The as-prepared ZnO NWs were found to be photoactive under ultra violet (UV) illumination. UV photosensor devices fabricated using these NW assemblies demonstrated a high photodetection abilities at room temperature under moderate UV illumination power of ~ 250 μW/cm2. These findings indicate the possibility of using ZnO NWs, grown using the same seeding method, for various opto-electronic applications. The same seeding technique was also used to grow ZnO NWs onto aligned multi-wall carbon nanotubes (MWCNTs), which were synthesized by using air assisted chemical vapor deposition (CVD) onto a SiO2/Si substrate. This ZnO NW/MWCNT hybrid structure was characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and Raman spectroscopy. The fabricated structure was used as an electrode for supercapacitor (SC) measurements. Good electrochemical performance was accomplished with a specific capacitance of ~192 F/g along with a maximum energy density of ~3.8Wh/kg and a high power density of ~ 28 kW/kg. The fabricated device showed high stability and it retained over 99% of its initial specific capacitance value after 2000 cycles. In addition, we report on the synthesis & electrochemical characterization of two-dimensional Zinc-Aluminum (ZnAl) layered double hydroxides (LDHs) directly grown on Al substrate by using CBD method. After details structural characterization by SEM, Raman spectroscopy, EDS elemental mapping, and X-ray powder diffraction (XRD), the electrochemical performances of an electrode fabricated based on this material were evaluated via cyclic voltammetry and galvanostatic charge-discharge using various electrolytes. The ionic electrolyte device showed a maximum specific capacitance of 120 F/g along with a maximum energy density of 5.17 Wh/Kg and a high power density of 8.4 kW/h. Additionally, we found that a high specific capacitance value of 358 F/g was achieved using an aqueous electrolyte.

ABSTRACT: Composites based on polyaniline and nanostructured zinc oxide were synthesized by mechanical mixing and the method of in situ polymerization and their physicochemical properties were studied. The electrical conductivity, surface structure and morphology of composites have been investigated. It is shown that the method of synthesis and quantity of filler affects the morphology and physicochemical properties of composite materials. An addition of various quantities of mineral filler to composite allows controlling conductivity of obtained materials. XRD-analysis of composite materials synthesized by in situ polymerization confirms the interaction of the components of the composite.
