Nanoflower

From Wikipedia, the free encyclopedia

A nanoflower, in chemistry, refers to a compound of certain elements that results in formations which in microscopic view resemble flowers or, in some cases, trees that are called nanobouquets or nanotrees.[1] These formations are nanometers long and thick so they can only be observed using electron microscopy.[2]

Production[edit]

Several ways to produce nanoflowers are known:

Nanomeadow[edit]

In supercapacitors, energy is stored because the electrodes are coated with a porous material that soaks up ions like a sponge, usually activated carbon. Nanomeadow supercapacitors store ions in manganese oxide (MnO), a material with a much greater capacity for ions than activated carbon.[4]

Scientists at Research Institute of Chemical Defence (Beijing, China) and Peking University created a nanomeadow of microscopic structures, fuzzy flowers of MnO each about 100 nanometres across on a field of messy carbon nanotube grass grown on a tantalum metal foil. Nanomeadows perform 10 times better than MnO alone and can store twice as much charge as the carbon-based electrodes in existing ultracapacitors.[4]
