World’s first graphene speaker already superior to Sennheiser MX400

By - April 15, 2014 4 Pictures
Graphene is frankly just showing off at this point. Not content with breezing in and smashing records in solar efficiency, kicking the butt of lithium-ion batteries, being the strongest known material in the Universe, being 1,000 times more light-sensitive than any known camera sensor and a thousand other achievements, now this smug supermaterial is having a crack at audio. How’s it going? Well, with basically zero acoustic development, a graphene loudspeaker is already boasting a better frequency response curve than a set of Sennheiser MX-400s. Read More

Graphene light detector could put heat vision tech in a contact lens

By - April 13, 2014 1 Picture
Thermal imaging has already found its way onto smartphones, but a team of researchers from the University of Michigan (U-M) have gone even further with the creation of an ultrathin graphene-based light detector. Being only slightly thicker than two sheets of graphene, the approach has the potential to put infrared heat detecting technology into a contact lens. Read More

Stanford scientists find a new way to turn graphite into diamond

By - April 3, 2014 3 Pictures
Pressure makes diamonds, but according to recent findings, there may also be a much quicker, hassle-free way. A team of researchers at Stanford University has stumbled upon a new way of turning graphite (the material used for pencil leads) into a diamond-like carbon structure simply by applying hydrogen over a platinum substrate, without the need to apply external pressure of any kind. The discovery could lead to easier and more flexible manufacturing of diamonds used in cutting tools and other industrial devices. Read More

Graphene-based nano-antennas may enable cooperating smart dust swarms

By - February 3, 2014 1 Picture
Smart dust. Utility fog. Programmable matter. Grey and blue goo. Cooperating swarms of micron-sized devices (motes) offer completely new solutions and capabilities that can hardly be imagined. However, cooperation requires communication, and conventional radio or optical networking simply isn't practical at this size. Now researchers at Georgia Tech have invented a plasmonic graphene nano-antenna that can be efficiently used at millimeter radio wavelengths, taking one more step toward smart dust. Read More

New materials mimic electronic properties of graphene in 3D

By - January 22, 2014 3 Pictures
Exciting times are ahead in the high-tech industries with the discovery by three independent groups that a new class of materials mimic the special electronic properties of graphene in 3D. Research into these superfast massless charge carriers opens up a wide range of potential applications in electronics, including smaller hard drives with more storage capacity, faster transistors and more efficient optical sensors.

Graphene-based solar cell hits record 15.6 percent efficiency

By - January 14, 2014 1 Picture
In 2012, researchers from the University of Florida reported a record efficiency of 8.6 percent for a prototype solar cell consisting of a wafer of silicon coated with a layer of graphene doped with trifluoromethanesulfonyl-amide (TFSA). Now another team is claiming a new record efficiency of 15.6 percent for a graphene-based solar cell by ditching the silicon all together. Read More
