SYMPOSIUM H The sol-gel science has undergone a spectacular development in the last thirty years. The various stages of the sol-gel process have been scrutinized in considerable detail and a solid basis for technological development established. The studies, mainly centered on silica and silicate glasses in the beginning, were progressively extended to many ceramics, polymers and composites. A turning point was reached in the early of 1980's with the emergence of organic-inorganic nanocomposites. This opened the gateway to whole classes of new materials with tailored properties in any imaginable form (thin and thick films, fibers, membranes, nanopowders, bulk porous or dense ceramics), composition, morphology and structure. The present studies show a definite tendency towards very specialized high-tech applications in many diverse fields such as separation techniques, catalysis, smart coatings, sensors, photonics, biomedical implants, drug delivery, and electronic components. The average number of paper published in sol-gel by Brazilian groups (ISI indexation, key words: sol-gel, Brazil) has grown from 6 up to 82 paper/year between the 90's first years to today. This symposium will address both fundamental and applied aspects of design and construction of functional sol-gel materials. Properties and applications of functional sol gel materials as well as the development of advanced characterization methods will also be included. Topics of interest include:Dentre os tópicos de interesse do simpósio destacam-se:
