Nanofoams are a class of nanostructured, porous materials, foams, containing a significant population of pores with diameters less than 100 nm. Aerogels are one example of nanofoam.
In 2006, Dr. Bryce Tappan, Dr. Steven F. Son and coworkers at Los Alamos National Laboratory discovered a technique for producing metal nanofoams by igniting pellets of energetic metal bis(tetrazolato)amine complexes. Nanofoams of iron, cobalt, nickel, copper, silver, and palladium have been prepared through this technique. These materials exhibit densities as low as 11 mg/cm3, and surface areas as high as 258 m2/g. These foams are effective catalysts and are being investigated for other applications.

The Army's research and development arm has funded a three-year research program at University of California, San Diego investigating nanofoam for protection -- the first foam armor endeavor ever, the college said. "We're developing nanofoams that help ...

Most people do not consider foam to be a structural compound. They associate it with uses like packing peanuts for safely shipping fragile objects or cheap floatation devices. However, that may soon change with the development of a new nanostructured ...

The team discovered that the foam with the smallest pores -- the 10 nm pore-size nanofoam -- absorbed impacts the best. Larger foams suffered so-called "damage localization" when exposed to trauma. The energy absorbed was poorly distributed, leading to ...

Engineers at the University of California, San Diego (UCSD) are developing a type of nanofoam that may one day provide better structural integrity for buildings compare to current conventional foam material. The nanofoams are made of porous, ...

It's the bane of cyclists around the world, but now the hassle of a puncture could be about to become history. A bike tyre that never gets a puncture because it is devoid of air is to go on sale. The solid tyres, which weigh the same as a normal tyre ...

Tiny particles of carbon that look like sooty foam and attract magnets have been made by Australian scientists. This new form of carbon nanoparticle, called nanofoam, surprised the researchers as it was the first type of carbon to have magnetic properties.
