De-icing aircraft with a carbon nanotube web

Image credit: Wikimedia Commons If you’ve ever had a flight delayed by a snow-covered runway, you’ll know that cold weather can be the enemy of air travel. But far from the ground, ice has even more serious implications. As an aircraft flies through clouds at sub-zero temperatures, super-cooled water droplets can form layers of ice on aerodynamic surfaces...


Turning sunlight into steam, thanks to graphene

Could a graphene aerogel get us a step close to efficient, solar-powered wastewater treatment? All over the world, solar photovoltaics are being used to transform sunlight into electricity. But, visible light isn’t the only energy source our sun offers. Solar thermal systems, widely used in cities such as Sao Paulo, make use of the sun’s heat. Dark panels...
