Superstrong materials for electric spaceplanes instead of space elevators

China has carbon nanotube bundles in the lab that are 20 times stronger than kevlar. They are trying to scale them up for mass production. If they succeed in mass producing tons of this material then what has been impossible become possible engineering. Superstrong materials were the key part of molecular nanotechnology speculation. Carbon nanotube …

CNT bundle material for flywheels 40 times better than batteries

In the lab, China has small quantities of carbon nanotube bundles 20 times stronger than Kevlar. These are ultralong (several centimeters) 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, …

NASA funds improvement of Miralon to double CNT composite strength

NASA awarded a potential $8.1 million dollar contract to Nanocomp Technologies, now part of Huntsman, for the “continued improvement of manufacturing high-strength CNT yarn/tape for use in developing CNT composites with strength properties at least double that of carbon fiber composites in use today. Successful improvement of this nanotechnology that could enable lighter spacecraft and …

CNT for optical-based quantum cryptography and quantum computing

Researchers at Los Alamos and partners in France and Germany are exploring the enhanced potential of carbon nanotubes as single-photon emitters for quantum information processing. Nanotubes integrated into electroluminescent devices can provide greater control over timing of light emission and they can be feasibly integrated into photonic structures. They are highlighting the development and photophysical …

25+ year journey to superstrong carbon nanotube bundles

In 1991, Sumio Iijima’s discovered multi-walled carbon nanotubes in the insoluble material of arc-burned graphite rods and Mintmire, Dunlap, and White’s independent prediction that if single-walled carbon nanotubes could be made, then they would exhibit remarkable conducting properties helped create the initial buzz that is now associated with carbon nanotubes. Nanotube research accelerated greatly following …

Breakthrough 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 strength of macroscale CNTBs is still 5–24 times that of any other types of engineering …

Superbridge 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 km, respectively). The Straits of Bab al Mandab bridge would be intercontinental bridges between the …

Carbon 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 activate systolic arrays of CNT cells it claims are relatively easy to sputter on to …

Carbon 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 scale, the material is stronger than steel, but because graphene is so thin, it is …

Cheap, 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 a way to make disperse carbon nanotubes at unprecedentedly high concentrations without the need for …
