carbon nanotubesBreakthrough Carbon nanotube bundles are over 20 times stronger than Kevlar

Finally ultralong (several centimeter) carbon nanotube fibers have been made into stronger bundles. The tensile strength of CNTBs (Carbon nanotube bundles) is at least 9–45 times that of other materials. If a more rigorous engineering definition is used, the tensile …

carbon nanotubesSuperbridge over Gibraltar

Carbon nanotube bundles are becoming a feasible and economically convenient solution for the realization in our time of super bridges, such as those required across the Straits of Bab al Mandab, Messina or Gibraltar (main spans ∼2.7, 3.3 or 3.5 …

carbon nanotubesCarbon nanotube NRAM computer memory will start to ship in 2019

Nantero is developing next-generation memory using carbon nanotubes. NRAM’s has DRAM-like speed, nonvolatility and low cost. Nantero and its partner Fujitsu aims to ship a DDR4 DRAM alternative using the technology in 2019. Nantero’s non-volatile NRAMs use electrostatic charge to …

carbon nanotubesCarbon nanotube reinforced graphene is twice as tear resistant

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 …

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

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

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

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

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

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

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) …
