The most commonly-used water filtration media are silicon gels and activated carbon. These can only be used once, however. By contrast, not only can filters made with carbon nanotubes be reused, but they're also reportedly more effective at removing organic pollutants.

Graphene spends most of its time in a 2D form, but now a team at Rice University have used carbon nanotubes to reinforce graphene foam. The resulting 3D material can be molded into any shape, supports 3,000 times its own weight before springing back to its original height.

Researchers at MIT have invented a printing process that could turn a lot of potential breakthroughs, such as electricity-generating clothing and smart sutures, into an inexpensive reality.

ScienceWater normally freezes at 0° C (32° F) and boils at 100° C (212° F) at sea level. But MIT researchers have found that when contained inside carbon nanotubes, water can freeze solid at temperatures well above its usual boiling point, which could allow the creation of proton-conducting “ice wires”.

ScienceThe strength of spinach isn't only in its nutrients, but also in its ability to be hacked to function as a sensor able to detect things like explosives, according to researchers at the Massachusetts Institute of Technology.

China-based scientists have discovered that by feeding graphene and carbon nanotubes to silkworms, the silk they produced was much stronger and could take on the ability to conduct electricity.
-
They're not the first transistors created using carbon nanotubes (CNTs), but researchers at the University of Wisconsin-Madison (UW-Madison) claim their new carbon nanotube transistors are the first to outperform the best silicon transistors available today.
-
Scientists at LLNL have developed a material that begins to bridge the gap between breathable and protective military clothing, using carbon nanotubes to actively block contaminants while still allowing water vapor to escape.
-
ScienceManipulating carbon nanotubes can be tricky, considering that their diameter is about 50,000 times smaller than a human hair. Researchers have just come up with a way to force carbon nanotubes to get in line – literally – by using electrical pulses and a vortex created by laser light.
-
Using a phenomenon dubbed "Teslaphoresis," researchers have made carbon nanotubes self-assemble to form a circuit linking two LEDs and then used the energy from that same field to power them
-
ScienceResearchers at MIT have developed a new method for detecting elusive molecules, using an array or “forest” of carbon nanotubes. The technique can be finely tuned, allowing it to be used for the capture of very small particles, including those of certain viruses.

A new light-capturing antenna created by researchers at Georgia Tech is able to convert visible light into usable direct current – an innovation that may help double the efficiency of solar energy harvesting.
