Synopsis: Materials: Classes of materials: Aerogel:

Volman suggests the material would make a compelling competitor to recently touted nanotube-based aerogels for deicing airplanes in the winter. e have the technology;

Previous success in the field of ultra-lightweight"aerogel monoliths"has relied largely on the use of precious gold and silver nanowires.

"Aerogel monoliths are like kitchen sponges but ours are made of ultra fine copper nanowires, using a fabrication process called freeze drying,

"The copper aerogel monoliths are conductive and could be embedded further into polymeric elastomers extremely flexible,

"Despite its conductivity, copper's tendency to oxidation and the poor mechanical stability of copper nanowire aerogel monoliths mean its potential has been unexplored largely.

The researchers found that adding a trace amount of poly (vinyl alcohol)( PVA) to their aerogels substantially improved their mechanical strength

the aerogels could be used to make electrically conductive rubber materials without the need for any prewiring.

the researchers noted that devices using their copper-based aerogels were not quite as sensitive as those using gold nanowires,

"We found that for a material as light and sparse as aerogel a kind of glass foam,

"However, because of its microarchitected layout, it performs with four orders of magnitude higher stiffness than unstructured materials, like aerogels, at a comparable density."

This catalyst is a stable carbon aerogel, or foam, with pores ranging from 2 to 50 nanometers in diameter, providing enormous surface area and room for the battery electrolyte to diffuse.

They polymerized molecules of the organic compound aniline into long chains in a phytic acid solution, then freeze-dried the three-dimensional hydrogel into an aerogel."

To do that, the researchers heated the aerogel to 1, 000 degrees Celsius in the absence of oxygen.

The foam-like batteries and supercapacitors were made using an aerogel material taken from tree fibres,

and release power much faster than batteries-were made out of a wood-based aerogel. To create this aerogel, the team first broke down cellulose,

the fibre found in trees, making it around one million times thinner. They then dissolved this nanocellulose and freeze-dried it,

"This aerogel is coated then with a special ink that conducts electricity within the aerogel, giving it the electronic properties that a battery requires.
