Semiconducting, mesoporous, glassy SiOC shows potential as sensor material

By Eileen De Guire / August 30, 2013

Glassy SiOC sensors responded well to NO2 below 400°C. Above 400°C, sensitivity to NO2 disappears, and they become responsive to H2, but the concentration is much higher—5 ppm for NO2 compared to 2,000 ppm for H2.

Transformed aerogels: From amorphous carbon to nanocrystalline diamond

By Eileen De Guire / June 1, 2011

Laser-heated diamond anvil cell allows very large hydrostatic pressure to be applied to amorphous carbon aerogels. Cavity dimensions are approximately 100–170 μm wide by 35 μm thick. Credit: LLNL. While there has been considerable interest in capturing the properties of diamond in a low-density form, converting an amorphous carbon aerogel to a crystalline phase without…

Carbon nanotubes as super sponges

By / November 12, 2009

Chinese scientists say they have figured out a way to turn carbon nanotubes into a superabsorbing and reusable sponge for organic materials. They predict their CNT sponge material may be particularly valuable in applications such as oil spills on ocean, lake and river surfaces because the material won’t absorb water. Their work is reported in…

Aerogels

By / April 9, 2009

Aerogel is wispy, translucent, highly insulating material often described as “solid smoke.” It’s worth noting that aerogel is not a new material and may date back to the 1930s.

Birdair to show aerogel membrane roofing systems

By / March 24, 2009

Although there is a tendency to associate aerogel with more exotic applications, one of the frustrations has been finding ways to incorporate the temperamental material into common large-scale manufacturing and applications, such as insulation. Some enterprises, however, are plugging away at the problems and are succeeding in making greater use of aerogel. One example is…
