Toward the Optimization of Low-temperature Solution-based Synthesis of ZnO Nanostructures for Device Applications

One-dimensional (1D) nanostructures (NSs) of Zinc Oxide (ZnO) such as nanorods (NRs) have recently attracted considerable research attention due to their potential for the development of optoelectronic devices such as ultraviolet (UV) photodetectors and light-emitting diodes (LEDs). The potential of ZnO NRs in all these applications, however, would require synthesis of high crystal quality ZnO NRs with precise control over the optical and electronic properties. It is known that the optical and electronic properties of ZnO NRs are mostly influenced by the presence of native (intrinsic) and impurities (extrinsic) defects. Therefore, understanding the nature of these intrinsic and extrinsic def...

Chemically Modified Metal Oxide Nanostructures Electrodes for Sensing and Energy Conversion

The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules. The second aspect is to fabricate a photo-electrochemical (PEC) cell. The biocompatibility, excellent electro-catalytic activities and fast electron transfer kinetics accompanied with a high surface area to volume ratio; are properties of so...

Synthesis and Characterization of Some Nanostructured Materials for Visible Light-driven Photo Processes

Nanostructured materials for visible light driven photo-processes such as photodegradation of organic pollutants and photoelectrochemical (PEC) water oxidation for hydrogen production are very attractive because of the positive impact on the environment. Metal oxides-based nanostructures are widely used in these photoprocesses due to their unique properties. But single nanostructured metal oxide material might suffer from low efficiency and instability in aqueous solutions under visible light. These facts make it important to have an efficient and reliable nanocomposite for the photo-processes. The combination of different nanomaterials to form a composite configuration can produce a materia...

Synthesis and Characterization of ZnO/Graphene Nanostructures for Electronics and Photocatalysis

Recent rapid development of electronics and electro-optical devices demands affordable and reliable materials with enhanced performance. Forming nanocomposites of already well-known materials is one possible route towards novel functional materials with desirable synergistic enhanced properties. Incompatible chemical properties, mismatched crystal structures and weak bonding interactions between the substances, however, often limit the number of possible nanocomposites. Moreover, using an inexpensive, facile, large-area and flexible fabrication technique is crucial to employ the new composites in industrially viable applications. This thesis focuses on the synthesis and characterization of d...

The central focus of this book is a small but vitally important group of movements that constitute a distinct 'fifth wave' of modern terrorism, here called the "New Tribalism". Terrorist Groups and the New Tribalism examines a collection of terrorist or insurgent movements whose similarity in tactics, strategic vision and desire to radically reshape their worlds to conform with a ‘Golden Age’ dream of perfection which is to be achieved through a genocidal or ethnic cleansing process to make way for the emergence of a new, radically perfected tribal utopia in a single generation. These shared strategic and tactical factors allow them to be examined through a comparative lens as a distinct...

The Failure of Grassroots Pan-Africanism

A work of masterful scholarship and powerful feeling, The Failure of Grassroots Pan-Africanism traces the history of a Pan-Africanist inspired non-aligned trade union federation, the All-African Trade Union Federation (AATUF) set up in 1961. This thoroughly researched analysis establishes the multiple causes of the tragic failure of the AATUF to fulfill its mission
