Book Description
Volume 29 of Reviews in Mineralogy provides an updated silica review which focuses on the most recent developments. This book describes the crystal structures and phase transitions of silica and its stuffed derivatives; bridges the relationship between the microstructural character of real silica minerals and the behavior of silica in the geological environment; covers Quantum mechanical considerations of the Si-O bond; shows how calculations based upon first-principles theory can explain and predict silica transitions at high temperatures and pressures; covers spectroscopic analyses of silica and how they reveal vibrational behaviors in response to variations in temperature, pressure, and composition and finally details the uses of silica for industrial purposes.

Book Description
Written by a leading practitioner and teacher in the field of ceramic science and engineering, this outstanding text provides advanced undergraduate- and graduate-level students with a comprehensive, up-to-date Introduction to Phase Equilibria in Ceramic Systems. Building upon a concise definition of the phase rule, the book logically proceeds from one- and two-component systems through increasingly complex systems, enabling students to utilize the phase rule in real applications. Unique because of its emphasis on phase diagrams, timely because of the rising importance of ceramic applications, practical because of its pedagogical approach, Introduction to Phase Equilibria in Ceramic Systems offers end-of-chapter review problems, extensive reading lists, a solid thermodynamic foundation and clear perspectives on the special properties of ceramics as compared to metals.This authoritative volume fills a broad gap in the literature, helping undergraduate- and graduate-level students of ceramic engineering and materials science to approach this demanding subject in a rational, confident fashion. In addition, Introduction to Phase Equilibria in Ceramic Systems serves as a valuable supplement to undergraduate-level metallurgy programs.

Book Description
In addition to the stable silica polymorph quartz, several metastable silica phases are present in Yucca Mountain. The conversion of these phases to quartz is accompanied by volume reduction and a decrease in the aqueous silica activity, which may destabilize clinoptilolite and mordenite. The primary reaction sequence for the silica phases is from opal or glass to disordered opal-CT, followed by ordering of the opal-CT and finally by the crystallization of quartz. The ordering of opal-CT takes place in the solid state, whereas the conversion of opal-CT takes place through dissolution-reprecipitation involving the aqueous phase. It is proposed that the rate of conversion of opal-CT to quartz is controlled by diffusion of defects out of a disordered surface layer formed on the crystallizing quartz. The reaction rates are observed to be dependent on temperature, pressure, degree of supersaturation, and pH. Rate equations selected from the literature appear to be consistent with observations at Yucca Mountain.

Book Description
This book is a comprehensive compilation of modern and cutting-edge chromatographic techniques written by pharmaceutical industry experts, academics, and vendors in the field. This book is an inclusive guide to developing all chromatographic methods (such as liquid chromatography and gas chromatography). It covers modern techniques for developing methods using chromatographic development software, requirements for validations, discussion on orthogonality, and how to transfer methods from HPLC to UHPLC. The text introduces some newer techniques that are heavily employed by chemists analyzing proteins and RNAi, as well as novel techniques such as counter current chromatography. This book is valuable for both the novice starting out in undergraduate labs and those who are new to the pharmaceutical industry and is a useful reference for seasoned analysts.
