Graphene

There’s plenty of ambient radiation just floating around in the air, and now MIT researchers have laid out the blueprints of a system that could tap into this wasted energy source and use it to charge electronic devices.

A research team at the University of Illinois at Urbana-Champaign has uncovered an exciting new possibility for crumpled graphene, finding it can serve as the basis of an ultra-sensitive biosensor for early cancer diagnosis.

If someone is suffering from a chronic wound, it's important for their doctor to continuously know the status of that injury. A new bandage is designed to keep physicians in the loop, via everyone's favorite wonder material – graphene.

Scientists at Rice University are reporting a big breakthrough in the area of graphene production, demonstrating a new processing technique that can convert a wide range of trash products into “flash graphene” in a cheap and efficient manner.

Graphene is already known for being incredibly strong, so how can it be made even stronger? By turning it into sheets of diamond, of course. Researchers in South Korea have developed a new method to convert graphene into ultrathin diamond films.

A new solar-powered catalyst made of graphene and titanium dioxide nanoparticles can pluck pollutants out of the air, much more efficiently than others. The catalyst could be coated onto building or street surfaces to improve air quality in cities.

Devices such as digital cameras electronically measure levels of high-energy light, and that's good enough for most of us. Now, however, scientists have developed a mechanical alternative that works with almost all types of light.

Researchers at Rice University have developed a new air filter made of graphene foam, which can kill captured microbes with small zaps of electricity.

Stanford University engineers have developed an ultra-thin heat shield for electronic devices that measures just 10 atoms thick.

Scientists are getting good results at repelling mosquitoes using graphene.

Since electronics are always shrinking, engineers need to find ways to make smaller components too. Now, scientists from the University of Leeds have managed to make the thinnest gold ever created, measuring just two atoms thick. That makes it functionally two-dimensional, joining graphene.

A team from Stanford has shown that graphene arranged in a specific way can generate a magnetic field. That’s surprising enough, but it turns out this particular form of magnetism has previously only been theorized.
