A new type of carbon nanotube (CNT) sponge that contains sulfur and iron has been developed and is proving to be more effective at soaking up water contaminants, such as oil, fertilizers, pesticides and pharmaceuticals, than previously seen. The magnetic properties of these nanosponges also make them easier to retrieve from the environment once the clean-up job is done.  Read More

Your furniture could kill you. According to the US National Fire Protection Association, nearly 20 percent of home fire deaths between 2006 and 2010 occurred in fires where upholstered furniture was the first item to ignite. It's actually not so much the exterior fabric that burns, as it is the foam beneath it. With that in mind, scientists at the National Institute of Standards and Technology (NIST) have used carbon nanotubes to create a coating for that foam, that reduces its flammability by 35 percent.  Read More

The scene at Ontario's Rod and Gun Club, where Garrison Bespoke's new bulletproof three-pi...

In a scene only dreamt of by most people, the employees of Garrison Bespoke, an upscale Toronto tailor, lined up and waited their turn to stab their boss, Michael Nguyen, with a hunting knife. Mr. Nguyen emerged from the experience unscathed, thanks to a remarkable bulletproof business suit that has just been revealed to the public.  Read More

Scientists at the New Jersey Institute of Technology have joined the ranks of those from the Korea Advanced Institute of Science and Technology, Stanford University and LG, by creating prototype flexible batteries. Designed for use in electronic devices with flexible displays, they could conceivably be manufactured in any size or shape, or even made at home.  Read More

Rice University researchers say that carbyne, an elusive allotrope of carbon, could be twi...

Researchers at Rice University have used a computer simulation to calculate that carbyne, a monodimensional chain of carbon atoms, is twice as strong as carbon nanotubes and three times stiffer than diamond. If their findings are correct and the challenges posed by manufacturing it can be overcome, then carbyne could prove an incredibly useful material for a wide range of applications.  Read More

Plastic bags like these may one day be a common source of carbon nanotubes

Discarded plastic bags are if nothing else, certainly one of the most visible forms of litter out there. While it's possible to recycle some of them into other plastic products, scientists at Australia's University of Adelaide have found another use for them – they can be used in the production of high-value carbon nanotubes.  Read More

In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity.  Read More

Principal Investigator John Hagopian and his team have developed a new technique to apply ...

Super-black nanotechnology might sound like something ripped from the pages of a comic book, but instead of being in the hands of a super-villain, it's a NASA-researched technology that is set to make spacecraft instruments more sensitive without increasing their size. John Hagopian, an optics engineer at NASA's Goddard Space Flight Center, and his team have demonstrated the ability to grow a uniform layer of carbon nanotubes on oddly shaped platforms, which will extend the potential of the technology by allowing nanotubes to be grown on 3D components.  Read More

Columbia University researchers have come up with a way to produce large joined sheets of ...

A study conducted at Columbia University has revealed that even when stitched together from much smaller fragments, large sheets of graphene still retain much of their mechanical properties. The discovery may be a crucial step forward in the mass-production of carbon nanotubes that could be used to manufacture flexible electronics, ultra-light and strong materials, and perhaps even the first space elevator.  Read More

Researchers at University of Texas at Arlington have developed a novel means of creating m...

Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel.  Read More
