carbon nanotubesCheap, mass produced solvent can scalably make Carbon nanotube-based dough

No Comments
Northwestern University’s Jiaxing Huang is ready to reignite carbon nanotube research. And he’s doing so with a common chemical that was once used in household cleaners. By using an inexpensive, already mass produced, simple solvent called cresol, Huang has discovered …

carbon nanotubesProto-molecular nanotechnology – Programmable Molecular Fabrication of trillions of functionalized carbon nanotubes

No Comments
New York-based Mattershift has managed to create large-scale carbon nanotube (CNT) membranes that are able to combine and separate individual molecules. Mattershift designs and manufactures nanotube membranes for carbon-zero fuels, health and performance optimized air and water, and precision medicine. …

carbon nanotubesMass production of new class of carbon nanotube semiconductors is close

No Comments
University of Waterloo chemists have found a way to simultaneously control the orientation and select the size of single-walled carbon nanotubes deposited on a surface. That means the developers of semiconductors can use carbon as opposed to silicon, which will …

carbon nanotubesTwisted carbon nanotubes can harvest energy and store 250 watts per kilogram

No Comments
An international research team led by scientists at The University of Texas at Dallas and Hanyang University in South Korea has developed high-tech yarns that generate electricity when they are stretched or twisted. Researchers describe “twistron” yarns and their possible …

carbon nanotubesSpiders exposed to water with graphene make triple strength spider silk

No Comments
A research team, led by Professor Nicola Pugno at the University of Trento, Italy, succeeded in having their spiders produce silk with up to three times the strength and ten times the toughness of the regular material. This could pave …

carbon nanotubesCarbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

No Comments
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers Light-matter quasi-partic­les can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University (Germany) and the University of St Andrews (Scotland) …

3dNew 3-D carbon nanotube chip combines computing and data storage

No Comments
Instead of relying on silicon-based devices, a new 3D chip uses carbon nanotubes, which are sheets of 2-D graphene formed into nanocylinders, and resistive random-access memory (RRAM) cells, a type of nonvolatile memory that operates by changing the resistance of …

carbon nanotubesCarbon nanotube reinforce Composites can reduce space vehicle mass by 30%

No Comments
NASA’s Space Technology Mission Directorate (STMD) is keenly interested in nanotechnology – an approach that can reduce the mass and improve the performance of aerospace systems. NASA computer modeling analysis has shown that composites using carbon nanotube reinforcements could lead …

carbon nanotubesIBM has made Carbon nanotubes transistors smaller and faster than silicon

No Comments
IBM scientists have made carbon nanotube transistors smaller and faster silicon transistors. Carbon nanotube transistors have long had the potential to be better than silicon, but this is the first time when that promise has been realized. Now IBM and …
