While some EVs may have a decent range in warm locales, they're not so impressive in cold places. That's because their battery is powering not only the motor, but also the heating system. Now, however, engineers are developing technology that could keep drivers warm, without leaving them stranded.

By wrapping a rubber core in carbon nanotube sheets while stretched, scientists have been able to create a conducting fiber that stretches like an accordion. It could find application in exoskeleton limbs, morphing aircraft, and more.

Battelle has recently tested its carbon nanotube-base HeatCoat technology that it claims is lighter and less power hungry than conventional aircraft anti-icing systems. It also has no moving parts and could easily be retrofitted to existing aircraft.

A team at the University of Leeds has discovered that shaping gold nanoparticles in the form of minuscule tubes sees them take on a number of new properties, including the ability to be heated up to destroy cancer cells.

In an effort to improve the performance of lithium-ion batteries, scientists have turned to techniques used by snails to control the growth of their shells. Combining the method with a peptide that binds with materials used in cathodes promises to make batteries smaller and have longer lifetimes.

Stanford engineers have pioneered a new scalable 3D computer chip that tightly interconnects logic and memory, with the potential for giant leaps in performance and energy efficiency.

ScienceGiven that the sterotypical image of the world's northern regions involves howling winds, why don't we see more wind turbines in such places? Well, it's largely because those turbines' blades would ice up a lot. The Windheat Project is aiming to change that, with a wind turbine de-icing system.

ScienceAs electronic devices continue to get smaller, one question becomes increasingly pertinent – how will we power them? With that in mind, researchers have created a tiny battery that incorporates even smaller structures, known as nanopores.
-
ScienceA team of researchers at the University of Utah has integrated carbon nanotubes into a prototype explosives sensor. It can also detect illegal drugs and toxic chemicals such as nerve gas, reportedly doing so better than currently-used technologies.
-
A new low-cost flat panel light source with extremely low power consumption could pioneer a new generation of brighter, cheaper and greener lighting devices to rival the dominance of LEDs.
-
A nanotube-based anode for lithium-ion batteries can charge cells to 70 percent of their capacity in only two minutes and has a very long lifespan of ten thousand charge/discharge cycles.

ScienceA newly produced material is believed to be the "blackest" ever created. Vantablack is a pure carbon coating and absorbs 99.96 percent of incident radiation (solar energy as it hits the material's surface). Manufacturer Surrey NanoSystems believes that is the highest such figure ever recorded.
