Materials science Aerogel

Debra R. Rolison is head of Advanced Electrochemical Materials at the Naval Research Laboratory (NRL). She received a B.S. in chemistry from Florida Atlantic University in 1975 and a Ph.D. in chemistry from the University of North Carolina at Chapel Hill in 1980 under the direction of Royce W. Murray. Dr. Rolison joined the Naval Research Laboratory as a research chemist in 1980. Her research at NRL focuses on the influence of nanoscale domains on electron- and charge-transfer reactions, with special emphasis on the surface and materials science of aerogels, electrocatalysts, and zeolites. Her program creates new nano structured materials and composites for catalytic chemistries, energy storage and conversion (fuel cells, supercapacitors, batteries, thermoelectric devices), and sensors.

Bloor, D. and R. W. Khan. 1994. Encyclopedia of Advanced Materials. (4 vols.) Oxford, UK./ Tarrytown, NY Pergamon Press. Advanced materials are artificially produced to meet the requirements of particular applications. The rapid developments in this field are covered in more depth than was possible in the standard Encyclopedia of Materials Science and Engineering (1986) and its supplements. Examples of topics covered include aerogel catalysts, bicmiedical polymers, color in ceramics, fast ion conduction in ceramics, hydrogels, metal matrix composites, and oligomers. There is an excellent subject index and a wealth of illustrations.

The recent developments in science and technology require a more exact control of structure/ nanotexture and properties of various materials, including carbon materials. In order to meet the requirements for carbon materials, various novel carbonization processes have been proposed. In relation to electrochemistry, the following processes have to be mentioned template method, polymer blend method, defluorination of fluorinated hydrocarbons, and carbonization of organic aerogels [99],... 

The term Carbon Filter Process (CFP) has been proposed and accepted widely. Selected carbonaceous materials, e.g., activated carbons (ACs), carbon aerogels, and carbon fibers, act as filter materials, which deliver a high affinity (and, hence, high capacity) to CO2 but not to its balance gas. This, in turn, leads to a high selectivity of C02/balance gas (in most case, N2). Most importantly, along with the improvement in science and technology, it has been possible to synthesize carbon materials with...
