Transforming greenhouse gas CO2 into carbon nanotubes

Mar 21 6:41am Nanowerk Nanotechnology Spotlight
In two new studies, researchers show that cement plants can have their carbon dioxide exhaust eliminated while co-producing carbon nanotubes. They demonstrate that with their C2CNT (carbon dioxide into carbon nanotubes) process, a wide portfolio of tailored carbon nanotubes, such as those with special shapes or conductivity can be made. C2CNT is a straightforward process that transforms CO2 to carbon nanotubes by molten electrolysis with inexpensive (nickel and steel) electrodes and low voltage. This synthesis consumes only CO2 and electricity, and is constrained only by the cost of electricity.

Researchers discover that chaos makes carbon materials lighter and stronger

Mar 20 6:42am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
In the quest for more efficient vehicles, engineers are using harder and lower-density carbon materials, such as carbon fibers, which can be manufactured sustainably by baking naturally occurring soft hydrocarbons in the absence of oxygen. However, the optimal baking temperature for these hardened, charcoal-like carbon materials remained a mystery since the 1950s when British scientist Rosalind Franklin, who is perhaps better known for providing critical evidence of DNA's double helix structure, discovered how the carbon atoms in sugar, coal, and similar hydrocarbons, react to temperatures approaching 3,000 degrees Celsius (5,432 degrees Fahrenheit) in oxygen-free processing. Confusion over whether disorder makes these graphite-like materials stronger, or weaker, prevented identifying the ideal baking temperature for more than 40 years.
