Sol−Gel Capillary Microextraction
Analytical Chemistry, 2002Sol-gel capillary microextraction (sol-gel CME) is introduced as a viable solventless extraction technique for the preconcentration of trace analytes. To our knowledge, this is the first report on the use of sol-gel-coated capillaries in analytical microextraction.

Journal of Sol-Gel Science and Technology, 1997
Sol-gel processes show many promises for the development of low-loss, high-performance glass integrated optical circuits. Special attention is being paid to the preparation of composite glass films, where the properties of organic or inorganic dopant compounds included in the glass matrix are fully exploited.

Sol-gel chemistry involves nucleophilic reactions. The chemical reactivity of metal alkoxides toward hydrolysis, condensation and complexation mainly depends on the electronegativity of the metal atom, its coordination number and the steric hindrance of alkoxide groups. Silicon alkoxides are poorly reactive. Hydrolysis and condensation rates have to be

Solid State Ionics, 1992
Abstract The sol-gel synthesis of metal oxides offers new possibilities in the field of solid state ionics. The chemical design of molecular precursors allows a better control of the polymerization process so that taylor-made materials could be obtained.

The sol–gel-based modification of wood introduces chemical substances into wood in order to improve its characteristics and impart new properties. It stabilizes dimensions of wood (timber) components, increases its strength and resistance to water, and reduces cracking. Many sol–gel-based impregnations aim to protect against wood rot and fire.

Current Opinion in Solid State and Materials Science, 1997
Abstract Sol-gel processes have long been used for the powderless processing of glasses and ceramics. Novel materials have appeared during the past few years with the synthesis of hybrid organic—inorganic compounds. Intermediate between glasses and polymers, these nanocomposites open up new possibilities in the field of materials science.

The use of sol-gel chemistry has afforded the development of a diverse range of chemical sensors, due to the ease with which the process can be modified to tailor properties of the material such as porosity and hydrophobicity. Furthermore, sol-gel films can be deposited on a variety of substrates, thus allowing flexibility in sensor configuration. This
