Pouring Saltwater Over Graphene Generates Electricity

A team of Chinese scientists did an impossible-sounding thing. They created electricity simply by dragging a droplet of saltwater across a layer of graphene. No big fires, no greenhouse gases, no fuss. They created energy with just a miracle material and one of the most plentiful substances on Earth. » 4/15/14 11:15am Yesterday 11:15am

Someday You Could Save Your Files With Nothing But a Sticky Note

Today's slim, svelte computers look great. You, on the other hand, look like a total yutz fumbling around to plug a thumb drive into a USB port that's somehow perpetually upside down. What if saving your data was as easy as slapping a sticky note on your screen? That's what a design team proposes with this highly… » 3/11/14 7:00pm 3/11/14 7:00pm

The World's Thinnest LED Is Only 3 Atoms Thick

LEDs have come a long ways. From the early 70s when a bulky LED watch cost thousands of dollars to LG's announcement last month that it had created an OLED TV as thin as a magazine, these glowing little bits of magic have become wonderfully cheap and impossibly small. But guess what: they're about to get much smaller. » 3/10/14 3:20pm 3/10/14 3:20pm

Graphene's Newest Trick Is Fighting Deadly Blood Clots

Man, graphene is shaping up to be a real wonder-material (if it can make it out of the lab and into the real world). Chalk up another future use: a coating that eliminates blood clotting in medical devices by kickstarting the body's natural clot-fighting mechanism that lasts way longer than anti-clotting drugs.

New Form of Graphene Should Finally Make Graphene Electronics Possible

F0r years, scientists have struggled to build graphene-based electronics that could do the same thing as silicon superconductor chips. A new breakthrough from an international team of scientists might just change all that. These geniuses just invented a new form of graphene that's ten times more conductive. » 2/06/14 5:40pm 2/06/14 5:40pm

Scientists Develop 3D Quantum Matter That Performs Like Graphene

As two-dimensional graphene has become one of the most lusted-after materials in science, many have wondered if there might be a 3D counterpart that we could actually build things with. A team of scientists at the Berkeley Lab just offered an affirmative answer. Well, almost. » 1/17/14 2:40pm 1/17/14 2:40pm

Move Over Graphene: The Wonder Conductor of the Future May Be Stanene

When it comes to super materials, graphene seems to get all the attention. But a team of researchers has developed Stanene: a single layer of tin atoms that could just be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computers work at. » 11/25/13 8:00am 11/25/13 8:00am

These New Graphene Supercapacitors Could Finally Power An Electric Car

A team of South Korean scientists has developed a new graphene supercapacitor that can store almost as much energy as a lithium-ion battery, but charge in only 16 seconds. This makes it an ideal material to store braking energy and could be exactly what the electric car industry needs. » 11/12/13 6:00pm 11/12/13 6:00pm

This Graphene-Coated Silicon Power Cell Signals a Battery-Free Future

Imagine a future without batteries. But in the same future, your cell phone charges in minutes and stays charged for weeks. Thanks to the world's first silicon power cell, this future might not be so far away—and graphene is helping us get there. » 10/25/13 3:21pm 10/25/13 3:21pm

Dentists May Start Covering Teeth in Growth-Stimulating Diamond Dust

Looks like there's a new candidate for most awesome supermaterial in town. Dentists may soon start fighting bone loss by covering our teeth in itty bitty nanodiamonds, making repairing teeth quicker, cheaper, and much less painful. » 9/23/13 10:23am 9/23/13 10:23am

Graphene Computer Chips Run on Light Instead of Electricity

Thanks to improvements in fiber optics, most of the information that you consume on any given day is transported by light. Quite inefficiently, however, most computer chips need electricity to operate, and scientists haven't quite figured out how to make the leap to more futuristic materials. At least not until… » 9/16/13 11:39am 9/16/13 11:39am

Whoa, Graphene Can Make Other Metals 500 Times Stronger

We've heard about plenty of promising electronic applications for miracle material graphene from headphones, to super-fast transistors, to crazy camera sensors, and even solar-powered paint. But now scientists have found a way to leverage its raw strength, by using it to make metal up to 500 times stronger. » 8/28/13 11:00am 8/28/13 11:00am

We Can Now Print Ultrafast Graphene Chips for Flexible Electronics

Futurists are always talking about how flexible electronics will change our lives in amazing ways, but we've yet to see anything mind-blowing come to market. A team of scientists from the University of Texas in Austin, however, think they've found the key to changing that: ultrafast graphene transistors printed on… » 8/22/13 5:45pm 8/22/13 5:45pm
