Silica aerogel is the only material with a refractive index in that range. Our first attempts to produce aerogel were made at the Chemical Centre in Lund, where we used a small two litre autoclave.

Martin Hevia,Eduardo Rivera-Lópezed by extracting the liquid phase from a gel using supercritical drying (SCD). In this process, the portion of the gel originally occupied by liquid (normally alcohol) is replaced by a non-condensed gas with little or no associated shrinkage. Aerogel density therefore generally scales with the volum

In order to realize this potential a number of measures are being tested or applied in building construction, e.g. improvement of heating and control techniques, better heat insulation, active use of regenerative energy sources, and finally,

Radiation-Induced Optic Neuropathyuctivities can be implemented with evacuated highly porous powder, fiber or gel spacers. As these materials are load bearing, the thick pressure supporting steel or aluminum walls, generally employed in cryogenic storage tanks, can be substituted by thin and flat steel and plastic envelopes.

Praveen Jeyaseelan,Amanda D. Hendersoncellent superinsulating system for passive solar energy usage. For a 20 mm layer the thermal loss coefficient at ambient temperatures is in the order of k ≈ 0.5 W/(m. ·K) and thus extremely low compared to conventional translucent thermal insulations. Aerogel could be employed in modified house or T
