Oxyhydroxides, and Related Materials
This symposium will provide a highly interdisciplinary forum for scientists and engineers to present recent work related to the synthesis, processing, and application of oxides and related materials in aqueous environments. The symposium will focus on solution chemistry, modeling, new and traditional characterization techniques, and applications where aqueous synthesis and processing routes provide a potential advantage over other methods and where the water/solid interface chemistry is exploited directly. The underlying science of these topics is generic to studies being carried out in a broad spectrum of disciplines including geochemistry, colloid chemistry, materials science, ceramic engineering, chemical engineering, and corrosion engineering. It is the intent of the symposium to emphasize the fundamental aspects of these topics through the different, and often complementary, perspectives of the various disciplines.
Original papers are solicited in the following and related areas:
*Experimental and computer modeling aimed at providing detailed molecular models for reactions that occur at the water/solid interface
* Leaching, corrosion, and recrystallization mechanisms by which oxides, glasses, ceramics, and metals are altered or dissolved in aqueous media
* Metal ion hydrolysis and coordination chemistry including the properties and application of polynuclear metal cations
* Formation of powders and thin films under ambient and hydrothermal conditions including kinetics and modeling nucleation and growth
* Phenomena related to colloidal processing including dispersion, flocculation, flotation, and consolidation, such as classical phenomena (electrostatic, steric, and electrosteric stabilization), as well as frontier areas such as short-range forces
* New applications of traditional characterization techniques, as well as newer techniques including AFM and synchrotron radiation
* Material and chemical aspects of applications where aqueous synthesis and processing offer advantages over other routes (protective coatings, etc.) and where the aqueous/solid interface is exploited directly (sensors, etc.)
* Structural and thermodynamic aspects of oxides, oxyhydroxides, clays, and related materials that impact their response to aqueous environments such as pillaring and swelling of clays, growth in solution, etc.
* Acid-base and adsorption reactions at specific surface sites as probed by solution chemistry and surface science techniques - applications where materials design is desired to optimize adsorption (or desorption) or ion exchange
