Presents the physical and chemcial principles of the sol-gel process of ceramic preparation, at a level suitable for graduate students and practitioners in the field.

Sol-Gel Techniques for Glass Producers and Users provides technological information, descriptions and characterizations of prototypes, or products already on the market, and illustrates advantages and disadvantages of the sol-gel process in comparison to other methods. The first chapter entitled "Wet Chemical Technology" gives a summary of the basic principles of the sol-gel chemistry. The most promising applications are related to coatings. Chapter 2 describes the various "Wet Chemical Coating Technologies" from glass cleaning to many deposition and post-coating treatment techniques. These include patterning of coatings through direct or indirect techniques which have became very important and for which the sol-gel processing is particularly well adapted. Chapter 3 entitled "Bulk Glass Technologies" reports on the preparation of special glasses for different applications. Chapter 4 entitled "Coatings and Materials Properties" describes the properties of the different coatings and the sol-gel materials, fibers and powders. The chapter also includes a section dedicated to the characterization techniques especially applied to sol-gel coatings and products.

"They had just crossed the bridge into the United States. Their feet were now firmly planted on the soil that was their promised land. They had made it! Blessed be the Virgin of Guadalupe! Now they had no reason to fear the villistas, the carrancistas, the government, or the revolutionaries! Here they could find peace, work, wealth and happiness!" And so begins the story of the Garcia family, who like many of their compatriots, fled their homeland during the upheaval of the Mexican Revolution in search of a better life in the United States. Originally published in 1926 in San Antonio, Texas as El sol de Texas, the novel chronicles the struggles of two Mexican immigrant families: the Garcias and the Quijanos. Their initial hopes--of returning to their homeland with enough money to buy their own piece of land--are worn away by the reality of immigrant life. Unable to speak English, they find themselves at the mercy of unscrupulous work contractors and foremen: forced to work at backbreaking labor picking cotton in the fields, building the burgeoning Southwest railroad system, and working in Gulf Coast oil refineries. Considered the first novel of Mexican immigration, El sol de Texas / Under the Texas Sun depicts the diverse experiences of Mexican immigrants, from those that return to Mexico beaten down by the discrimination and hardship they encounter, to those who persist in their adopted land in spite of the racism they face. The original Spanish-language text is accompanied by the first-ever English translation by Ethriam Cash Brammer and an introduction by John Pluecker. Publication of this fascinating historical novel will provide unique insight into the long history of Mexicanimmigration to the United States and its implications for cultural, historical, and literary studies.

Sol-gel processing is a soft-chemistry method to obtain functional materials at low temperatures. This route can be used to produce very sophisticated nanomaterials and to tailor the materials to very specific applications. Adsorption and detection of pollutants, water purification and soil remediation represent challenging fields of application that can be exploited by sol-gel materials. In this volume several contributions from invited speakers and participants at the NATO advanced research workshop on "Sol-gel approaches to materials for pollution control, water purification and soil remediation", which has been held in Kiev, Ukraine on October 2007, are reported. The book offers a wide and updated overview of the most advanced sol-gel methods for materials processing and at the same time presents several case studies concerning possible solutions for environmental issues. General articles on sol-gel from the invited speakers and focused research articles allow getting inside sol-gel applications on this very important field.

Om den amerikanske kunstner Sol LeWitt, født 1928

A revelatory consideration of the wide-ranging practice of one of the most influential American artists of the 20th century A pioneer of minimalism and conceptual art, Sol LeWitt (1928–2007) is best known for his monumental wall drawings. LeWitt’s broad artistic practice, however, also included sculpture, printmaking, photography, artist’s books, drawings, gouaches, and folded and ripped paper works. From the familiar to the underappreciated aspects of LeWitt’s oeuvre, this book examines the ways that his art was multidisciplinary, humorous, philosophical, and even religious. Locating Sol LeWitt contains nine new essays that explore the artist’s work across media and address topics such as LeWitt’s formative friendships with colleagues at the Museum of Modern Art in the early 1960s; his photographs of Manhattan’s Lower East Side; his 1979 collaboration with Lucinda Childs and Philip Glass and its impact on his printmaking; and his commissions linked to Jewish history and the Holocaust. The essays offer insights into the role of parody, experimentation, and uncertainty in the artist’s practice, and investigate issues of site, space, and movement. Together, these studies reveal the full scope of LeWitt’s creativity and offer a multifaceted reassessment of this singular and influential artist.

This comprehensive three-volume handbook brings together a review of the current state together with the latest developments in sol-gel technology to put forward new ideas. The first volume, dedicated to synthesis and shaping, gives an in-depth overview of the wet-chemical processes that constitute the core of the sol-gel method and presents the various pathways for the successful synthesis of inorganic and hybrid organic-inorganic materials, bio- and bio-inspired materials, powders, particles and fibers as well as sol-gel derived thin films, coatings and surfaces. The second volume deals with the mechanical, optical, electrical and magnetic properties of sol-gel derived materials and the methods for their characterization such as diffraction methods and nuclear magnetic resonance, infrared and Raman spectroscopies. The third volume concentrates on the various applications in the fields of membrane science, catalysis, energy research, biomaterials science, biomedicine, photonics and electronics.
