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. |url=http://nanotechweb.org/cws/article/tech/19739 |title=Silicon carbide nanoflowers bloom - nanotechweb.org |publisher=nanotechweb.org |accessdate=2008-06-18 |last= |first= These formations are nanometers long and thick so they can only be observed using electron microscopy.{{cite web |url = http://www.sciencentral.com/articles/view.php3?type=article&article_id=218392630 |title = Nanoflowers: Science Videos - Science News - ScienCentral |publisher = www.sciencentral.com |accessdate = 2008-06-18 |last = Kalaugher |first = Liz |url-status = dead |archiveurl = https://web.archive.org/web/20080803080335/http://www.sciencentral.com/articles/view.php3?type=article&article_id=218392630 |archivedate = 2008-08-03

Production

Several ways to produce nanoflowers are known:

• A process similar to the making of a carbon nanotube using a hydrocarbon gas.
• Heating gallium (Ga) and then flowing methane (CH4) over, under specific pressure and heat. This forms flower-shaped silicon carbide (SiC) structures.
• Heating a molybdenum dioxide (MoO2) thin film on a piece of molybdenum foil surrounded by sulfur vapour.{{cite web |url=http://nanotechweb.org/cws/article/tech/17264 |title=Nanoflowers blossom in place of nanotubes - nanotechweb.org |publisher=nanotechweb.org |last=Kalaugher |first=Liz |accessdate=2008-06-18 |archive-url=https://web.archive.org/web/20160303231033/http://nanotechweb.org/cws/article/tech/17264 |archive-date=2016-03-03 |url-status=dead

Nanomeadow

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.

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.
