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...
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...
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...
Selected Studies in Geotechnics, Geo-informatics and Remote Sensing
This book contains the best papers accepted for presentation at the 3rd Springer Conference of the Arabian Journal of Geosciences (CAJG-3). The book is divided into three parts to distinguish research studies from the fields of (1) geological and geotechnical engineering, (2) geomechanical studies based on numerical and analytical methods, and (3) geo-informatics and remote sensing. The content of these papers provides new scientific knowledge for further understanding on landslides, new stabilization techniques, importance of geophysics for engineering geology investigations as well as new empirical approaches for easily predicting some physical and hydrogeomechanical properties of geomater...
Mother Tongue
A probing and poetic examination of language, food, faith, and family attachment in Italian life through the eyes of an American who moved to Parma with her husband and family. In the 1980s, the American writer Wallis Wilde-Menozzi moved permanently with her Italian husband and her daughter to Parma, a sophisticated city in northern Italy, where he became a professor of biology. Her search for rootedness in the city that was to be her home introduced her to complexities in her identity as she migrated into another language and looked for links beyond the joys of Verdi, Correggio, and Parmesan cheese, which visitors have rightly extolled for centuries. The local resistance to change perceived...

In Amreeka Zoned Out
This book is catharsis for me, and therapy for you. Sometimes this book hurt me to write, sometimes it may hurt to read. It is about broken souls, empty rooms, and the property of turning your miserable cracks into colorful mosaics. This book as about being foreign, both away and at home, about being Arab and Muslim. It is about faith and how sometimes you need to lose it to find it again. Channel all your old sads and hopefully we together can make new happies out of them, an alchemy of emotion. This book, above all, is about humility. Poetry is about realizing you are vulnerable, man or woman, rich or poor. Learn to embrace and love that. That is what living this book and writing it taught me. That the I should always be lowercase.
Who's who in the United Nations and Related Agencies
This directory contains information on key officials of the secretariat, agency and mission personnel, as well as leaders of related organizations. Also included is a descriptive overview of the United Nations System: organizational structure; member states; permanent missions in New York, Geneva, and Vienna; previous presidents of the General Assembly; principal officers; and depository libraries. All 3,000 entries include the following biographical information: full name, position/title, business address, nationality, languages spoken, date and place of birth, marital status, career positions, education, professional interests, publications, awards or honors, avocational interests, and residence address. Two biographical indexes -by organization and nationality -- provide easy access to all entries.
