This book was released on 2013 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc oxide is an n-type transparent conducting oxide (TCO), which is used in solar cells and optoelectronics devices. ZnO has the potential to become the future choice for a wide range of TCO commercial applications replacing the current, more expensive, and toxic indium-based materials. The isothermal grain growth of ZnO nano-powders with two different initial grain sizes and the effect of forming gas reduction on their electrical properties were studied at 900 °C. The particle size was determined using synchrotron x-ray diffraction data and scanning electron micrographs. The grain size, shape, trace impurities, and synthesis methods had an effect on the electrical performance of crystallites smaller than 300 nm. For grains larger than 300 nm, similar conductivity values were achieved regardless of the initial grain size and impurities. While grain growth modestly increased the electrical performance of ZnO, the exposure to reduction gases dramatically improved the conductivity by five orders of magnitude. Synchrotron x-ray diffraction data collected in situ at 500 °C also showed that reducing gases enhanced the grain growth of nanoparticles.

Download or read book Multifunctional Oxide Based Materials From Synthesis to Application written by Teofil Jesionowski and published by MDPI. This book was released on 2019-09-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.
