Novel nanotube structure strengthens thin films for flexible electronics

25-Apr-2017

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher ...

New method for 3-D printing extraterrestrial materials

18-Apr-2017

When humans begin to colonize the moon and Mars, they will need to be able to make everything from small tools to large buildings using the limited surrounding resources. Northwestern University's Ramille Shah and her Tissue Engineering and Additive Manufacturing (TEAM) Laboratory have ...

Carbon nanotubes self-assemble into tiny transistors

06-Apr-2017

Carbon nanotubes can be used to make very small electronic devices, but they are difficult to handle. University of Groningen scientists, together with colleagues from the University of Wuppertal and IBM Zurich, have developed a method to select semiconducting nanotubes from a solution and make ...

'Fuzzy' fibers can take rockets' heat

04-Apr-2017

To stand up to the heat and pressure of next-generation rocket engines, the composite fibers used to make them should be fuzzy. The Rice University laboratory of materials scientist Pulickel Ajayan, in collaboration with NASA, has developed "fuzzy fibers" of silicon carbide that act like Velcro ...

Reusable carbon nanotubes could be the water filter of the future

31-Mar-2017

A new class of carbon nanotubes could be the next-generation clean-up crew for toxic sludge and contaminated water, say researchers at Rochester Institute of Technology. Enhanced single-walled carbon nanotubes offer a more effective and sustainable approach to water treatment and remediation than ...

Reducing platinum need for electrocatalysts

Promising results obtained with a new electrocatalyst

27-Mar-2017

Platinum is a very expensive metal and it is therefore one of the bottlenecks hindering the growth of renewable energy. Platinum is used as the catalyst in electrolysers that store electric energy as chemical compounds, and it also plays an important role in fuel cells, catalytic converters and ...

Nanotube film may resolve longevity problem of challenger solar cells

21-Mar-2017

Five years ago, the world started to talk about third-generation solar cells that challenged the traditional silicon cells with a cheaper and simpler manufacturing process that used less energy. Methylammonium lead iodide is a metal-organic material in the perovskite crystal structure that ...

Graphene foam gets big and tough

16-Feb-2017

A chunk of conductive graphene foam reinforced by carbon nanotubes can support more than 3,000 times its own weight and easily bounce back to its original height, according to Rice University scientists. Better yet, it can be made in just about any shape and size, they reported, demonstrating a ...

Cell-tracking agents get a boost

31-Jan-2017

Rice University researchers have synthesized a new and greatly improved generation of contrast agents for tagging and real-time tracking of stem cells in the body. The agent combines ultrashort carbon nanotubes and bismuth clusters that show up on X-rays taken with computed tomography (CT) ...

3-D printing and nanotechnology, a mighty alliance to detect toxic liquids

12-Jan-2017

Carbon nanotubes have made headlines in scientific journals for a long time, as has 3D printing. But when both combine with the right polymer, in this case a thermoplastic, something special occurs: electrical conductivity increases and makes it possible to monitor liquids in real time. This is a ...
