Fracture-resistant “rebar graphene” is more than twice as tough as pristine graphene. Rebar graphene, developed by the Rice lab of chemist James Tour in 2014, uses carbon nanotubes for reinforcement. Graphene is a one-atom-thick sheet of carbon. On the two-dimensional …

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 …

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 …

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 …

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) …

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 …

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 …
