Summary : Advanced materials and nanotechnology is a promising, emerging field involving the use of nanoparticles to facilitate the detection of various physical and chemical parameters, including temperature, humidity, pH, metal ion, anion, small organic or inorganic molecules, gases, and biomolecules responsible for environmental issues that can lead to diseases like cancer, diabetes, osteoarthritis, bacterial infections, and brain, retinal, and cardiovascular diseases. By monitoring environmental samples and detecting these environmental issues, advanced nanotechnology in this type of sensory technology is able to improve daily quality of life. Although these sensors are commercially available for the detection of monovalent cations, anions, gases, volatile organic molecules, heavy metal ions, and toxic metal ions, many existing models require significant power and lack advanced technology for more quality selectivity and sensitivity. There is room in these sensors to optimize their selectivity, reversibility, on/off ratio, response time, and their environmental stability in real-world operating conditions. This book explores the methods for the development and design of environmentally-friendly, simple, reliable, and cost effective electrochemical nanosensors using powerful nanostructured materials. More specifically, it highlights the use of various electrochemical-based biosensor sensors involved in the detection of monovalent cations, anions, gases, volatile organic molecules, heavy metal ions, and toxic metal ions, with the ultimate goal of seeing these technologies reach market.

Summary : This significantly extended second edition addresses the important physical phenomenon of Surface Plasmon Resonance (SPR) or Surface Plasmon Polaritons (SPP) in thin metal films, a phenomenon which is exploited in the design of a large variety of physico-chemical optical sensors. In this treatment, crucial materials aspects for design and optimization of SPR sensors are investigated and described in detail. The text covers a selection of nanometer thin metal films, ranging from free-electron to the platinum-type conductors, along with their combination with a large variety of dielectric substrate materials, and associated individual layer and opto-geometric arrangements. Whereas the first edition treated solely the metal-liquid interface, the SP-resonance conditions considered here are expanded to cover the metal-gas interface in the angular and wavelength interrogation modes, localized and long-range SP's and the influence of native oxidic ad-layers in the case of non-noble metals. Furthermore, a selection of metal grating structures that allow SP excitation is presented, as are features of radiative SP's. Finally, this treatise includes as-yet hardly explored SPR features of selected metal–metal and metal–dielectric superlattices. An in-depth multilayer Fresnel evaluation provides the mathematical tool for this optical analysis, which otherwise relies solely on experimentally determined electro-optical materials parameters.

Summary : The goal of this thesis is to produce NiO- and Ni(OH)2-carbon based nanocomposites and explore their possible adoption as active electrode materials in supercapacitor and gas sensing applications. Field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, thermal gravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and gas adsorption analyses were utilized to evaluate the structure and morphology of all samples in this study. The major aim of integrating carbon-based nanomaterials (graphene foam, graphene oxide and activated carbon) into Ni-based oxides and hydroxides in this study is to take advantage of their outstanding characteristics. These include good electrical conductivity, high corrosion resistance, large SSA, low-cost, good cyclic and temperature stability, as well as the capability to serve as a substrate for growth of other materials to form a suitable composite. The electrochemical evaluation as a potential supercapacitor electrode was employed in a three (3)-electrode configuration for the as-prepared Ni(OH)2/carbon based electrodes (NiOH)2/graphene foam and Ni(OH)2/graphene oxide electrodes) while the gas sensing characteristics of NiO/carbon-based electrodes were investigated using NCSM-CSIR gas sensing station controlled by a KEITHLEY pico-ammeter system. The electrochemical results of Ni(OH)2/carbon-based electrodes have demonstrated a superior electrochemical performance as compared to the pristine Ni(OH)2 electrodes with the results comparable and even better than some earlier related studies available in the literature. Similarly, NiO/carbonbased electrodes in the form of NiO/graphene foam and NiO/activated carbon electrodes both exhibited enhanced gas sensing properties in comparison to the pristine NiO electrode due to the increased specific surface area and electrical conductivity that are linked to its sensing response, response time and recovery time. Thus, the results obtained from these studies have clearly established the viability of these carbon-based nanomaterial composites as promising candidates for electrochemical supercapacitor and gas sensing applications.
