Nano-sponges on graphene make efficient filters of industrial wastewater

Engineers at the University of Vienna have developed a new composite material that makes an efficient filter for removing organic pollutants from water. The system uses super-porous “nano-sponges” embedded on a sheet of graphene.Continue ReadingCategor… Continue reading Nano-sponges on graphene make efficient filters of industrial wastewater

Graphene electronic-tattoo monitors blood pressure over time

Scientists have developed a new electronic “tattoo” that can monitor a patient’s blood pressure continuously. The e-tattoo is made of graphene and can be worn for long periods without getting in the way, allowing for better health data.Continue Reading… Continue reading Graphene electronic-tattoo monitors blood pressure over time

Waste plastics from old cars “flashed” into graphene to go in new cars

If humanity is ever going to curb our waste problem, we’ll need to get creative with recycling and reusing materials. In a new study, researchers at Rice University and Ford’s Research and Innovation Center have demonstrated how waste plastic from old … Continue reading Waste plastics from old cars “flashed” into graphene to go in new cars

“Catalytic condenser” lets cheap metals act like rare, expensive ones

It’s an unfortunate truth that many important chemical reactions require rare and expensive metals as catalysts. But now, scientists have developed a device that actively tweaks plain old aluminum to make it behave like other metals on the fly.Continue… Continue reading “Catalytic condenser” lets cheap metals act like rare, expensive ones

Recycled soot coating captures solar heat better than graphene

Tackling climate change doesn’t just require efforts like renewable energy – we need to clean up existing processes too. Now, engineers have developed a way to use soot from emissions to improve solar thermal devices, making them not only cheaper to pr… Continue reading Recycled soot coating captures solar heat better than graphene

Touchscreen tech swaps rare metal for graphene, with no performance drop

Indium is one of the rarest metals on Earth, but it’s a key ingredient in ubiquitous electronic devices. Engineers have now demonstrated a way to swap indium for graphene, to make devices with the exact same electronic properties.Continue ReadingCatego… Continue reading Touchscreen tech swaps rare metal for graphene, with no performance drop

Graphene used to create “world’s thinnest Christmas tree”

A couple of years ago, Canadian scientists celebrated the Christmas season by creating a microscopic gingerbread house. In that same spirit, Danish researchers have now produced what they claim is the world’s thinnest Christmas tree – and it’s made of … Continue reading Graphene used to create “world’s thinnest Christmas tree”
