This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this initial stage of the research on glasses with high water content, the hydrothermal units have been constructed and several water-bearing sodium silicate glasses have been prepared. Preliminary measurements were also made on thermal, mechanical, and electrical properties of these glasses. Several unique features have been revealed. For example, the electrical resistivity increases substantially with water content suggesting a possibility of preparing chemically durable glasses with large amounts of water.

Book excerpt: Silicate-based glasses are one of the most versatile materials in terms of technological perspective with a wide range of industrial applications. In most cases, glass products are exposed to various aqueous environments (either humid air or liquid water) and subject to physical contact with foreign objects, which leads to deterioration of chemical and mechanical properties of glass surfaces. Therefore, understanding their interactions with adsorbed interfacial water molecules is critical as it can provide physical insights needed for rational design of more durable glasses. Experimental characterization approaches have been applied to tackle difficult problems associated with the complex nature of glass surfaces but they are often limited by the time-scale resolution. As a result, they have failed to offer important structural characteristics and chemical reaction mechanisms under dynamic processes happening at the glass surface. To complement the challenges that experimental endeavors are encountering, this dissertation aims to provide a comprehensive understanding of water interactions of silicate glass surfaces using atomistic-scale simulations techniques. In particular, ReaxFF reactive force field-based molecular dynamics (MD) simulations are employed to study two distinct surface phenomena, i) surface water reaction and ii) surface mechanochemical wear process. These studies represent the surface damage process of silicate glass in the absence and presence of mechanical actions, respectively. The first part of this dissertation describes the water interactions of a silicate glass with readily leachable alkali (sodium) ions. In this study, highly complex surface chemistry, including proton/water exchange with the sodium ions, formation of relatively long-living sodium-hydroxide ionic complexes at the glass surface and eventual dissolution of those ion pairs into the water phase are described. Also, surface mapping of water binding energy to the glass surface is evaluated at different stages of the glass-water reaction, which would be relevant to assess the chemical durability of the glass materials based on the glass network topology. After the transport behavior and glass-water reaction mechanism at the surface has been identified, the mechanochemical wear process of sodium silicate glass rubbed with amorphous silica in the absence and presence of interfacial water molecules is covered in the second part of this dissertation. The effect of water molecules on the shear-induced chemical reaction at the sliding interface was investigated and the dependence of wear on the number of interfacial water molecules in ReaxFF-MD simulations was found to be qualitatively in reasonable agreement with the experimental data. The large-scale atomistic simulation approaches with ReaxFF reactive force field presented in this dissertation alleviates the limitations of DFT calculations and experiments, providing new and meaningful insights on the chemical dynamics associated within the glass-water interface.
Book Synopsis Mass Transport in Magmatic Systems by : Bjorn Mysen
Download or read book Mass Transport in Magmatic Systems written by Bjorn Mysen and published by Elsevier. This book was released on 2022-10-09 with total page 908 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass Transport in Magmatic Systems describes the properties and processes of these natural occurrences, including a description and discussions of how properties can be used for quantitative description of mass and energy transport on, and in, Earth and terrestrial planets. As the experimentally obtained chemical and physical properties of magma is scattered across literature, this book provides a comprehensive volume on the topic. Moreover, links between properties and processes are rarely appreciated. This makes it challenging for a non-experimentalist to access, evaluate, and apply such data. - Incorporates information from a range of subdisciplines, from materials science to geology, geophysics and geochemistry - Highlights links between properties and processes of magmatic systems - Presents chapters that can stand on their own, with practical applications and a section for non-expert readers

Book Synopsis Defects and Disorder in Crystalline and Amorphous Solids by : Richard Catlow
Download or read book Defects and Disorder in Crystalline and Amorphous Solids written by Richard Catlow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of defects and disorder in solids remains a central topic in solid state science. Developments in the field continue to be promoted by new experimental and theoretical techniques, while further impetus for the study of disorder in solids is provided by the growing range of applications of solid state materials in which disorder at the atomic level plays a crucial rOle. In this book we attempt to present a survey of fundamental and applied aspects of the field. We consider the basic aspects of defective crystalline and amorphous solids. We discuss recent studies of structural, electronic, transport, thermodynamic and spectroscopic properties of such materials. Experimental and theoretical methodologies are reviewed, and detailed consideration is given to materials such as fast ion conductors and amorphous semiconductors that are of importance in an applied context. Any survey of this large field is necessarily selective. We have chosen to emphasise insulating (especially oxidic) and semi-conducting materials. But many of the approaches and techniques we describe apply generally across the entire field of solid state science. This volume is based on a NATO ASI held at the Residencia Santa Teresa de Jesus, Madrid in September 1991. The Editor is grateful to the NATO Scientific Affairs Division for their sponsorship of this School. Thanks are also due to all who participated in and lectured at the school, but especially to the organising committee of A. V. Chadwick, G. N. Greaves, M. Grigorkiewicz, J. H. Harding and S. Kalbitzer. C. R. A.

Download or read book Effects of Composition, Pressure, and Temperature on the Elastic, Thermal, and Ultrasonic Attenuation Properties of Sodium Silicate Glasses written by and published by . This book was released on 1974 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic moduli of sodium silicate glasses have been measured by ultrasonic interferometry to 5 kbar (at 298K) and in the temperature range 80 to 498K. The values of pressure and temperature derivatives of the moduli become systematically less anomalous (i.e., more positive and more negative, respectively) with increasing Na2O content. Similarly, the mode Gruneisen parameters derived from the pressure dependence of elastic wave velocities, and the thermal Gruneisen parameters calculated from thermal expansivity data increase with increasing Na2O content. At low temperatures, the attenuation- temperature curves for these glasses show reversals. The attenuation peak at approximately 47K, found in fused silica, shifts to a higher temperature in these glasses as the Na2O is increased. Implications are discussed in terms of a network model.
