Aerogels are remarkable materials with unprecedented physical properties that fascinate researchers and space engineers. They have incredible insulating properties with regard to thermal, electrical and acoustic energy transfers. After  being used by NASA in various space experiments to capture cosmic dust, aerogels became, for the first time, the object of sculptural research. Dr. Iannis MICHALOU(di)S, Research Affiliate at the Center for Advanced Visual Studies at MIT tells us the story.

Toward molecular design of oxide precursors for advanced materials
by Liliane G. Hubert-Pfalzgraf

Chemical routes to materials are based on transformations in solution such as sol-gel processing, hydro or solvo thermal syntheses, Metal Organic Decomposition (MOD), or in the vapour phase chemical vapor deposition (CVD). Most chemical routes rely on the availability of appropriate “metal-organic” molecules as precursors. Among the various precursors of metal oxides namely metal
b-diketonates and metal carboxylates, metal alkoxides are the most versatile. They are available for nearly all elements and cost-effective synthesis from cheap feedstoks have been developed for some.
Professor Liliane G. Hubert-Pfalzgraf make the point.
Polyoxometalate-based organic-inorganic hybrid materials
The paper summarizes and reviews the current developments in the area of polyoxometalate (POM)-based organic-inorganic hybrid materials including POM-based organic- or organometallic-derived hybrid materials, charge transfer (CT) salts and organic-inorganic composite films. This review also provides insight into the rational synthesis and potential applications of these hybrid materials.
Smart Optical Materials by Sol-Gel Method
Professor Renata Reisfeld  and his research team from the Hebrew University of Jerusalem have investigated for more than a decade sol-gel derived optical materials. She give us today an overview of a broad palette of such materials, investigated by her group, and  potentially useful for sensors, lasers, solar energy concentrators, variable transmission windows, and light amplifiers.
Glass from Aerogels... 25 years ago
by Michel Prassas
25 years ago, glass scientists were intensively looking for low temperature processing routes for making glass. The discovery that monolithic gels can be transformed in glassy materials at half the conventional melting temperature, became a useless reality with extraordinary implications. The topic drained a great number of researchers from a variety of disciplines and open the window of what commonly call today the sol-gel process.  An open and versatile chemical processing route to  a variety of inorganic and organic-inorganic materials with nanotailored structures and properties. 
What are hybrids ?
by Prof. Clement Sanchez
An incredible amount of research investigations have appeared the last 10 years in the field of hybrids materials indicating the growing interest of chemists, physicists and materials researchers to fully exploit this technical opportunity for creating materials and device with benefits of the best of the two worlds namely inorganic and organic...
Wet Coating Technologies for Glass 
by H. Schmidt and  M. Mennig
One advantage of wet coating techniques is, that molecular structures developed by chemical synthesis can be used to develop new properties, or to develop new desired molecular structures by heat-treatment and subsequent chemical reaction on the surface. After introducing the advantages of wet coating technologies the authors describe the different wet coating techniques including, dip, spin silk screen, roll coating, laminar flow...
