Light bulb set to be graphene's first commercial consumer application

By - March 31, 2015 1 Picture
In two claimed firsts, researchers at the University of Manchester have produced both the first commercial application of graphene and the world's first graphene light-bulb. It is expected that this new device will have lower energy emissions, cheaper manufacturing costs, and a longer running life than even LED lights. And this isn't just a pie-in-the-sky prototype, either. The team who developed it believes that the graphene light-bulb will be available for retail sale within months. Read More

Robobug: Scientists clad bacterium with graphene to make a working cytobot

By - March 25, 2015 1 Picture
By cladding a living cell with graphene quantum dots, researchers at the University of Illinois at Chicago (UIC) claim to have created a nanoscale biomicrorobot (or cytobot) that responds electrically to changes in its environment. This work promises to lay the foundations for future generations of bio-derived nanobots, biomicrorobotic-mechanisms, and micromechanical actuation for a wide range of applications. Read More

Imperfect graphene may be perfect for use in better fuel cells

By - March 19, 2015 1 Picture
We already knew that graphene was a highly useful material, but just how useful is it? Well, it turns out that even defective graphene may be valuable. According to a team of mostly-American scientists, improperly-formed graphene could find use in next-generation fuel cells. Among other things, those cells might allow electric cars to be recharged in the amount of time that it currently takes to refuel a gas-burning vehicle. Read More

Graphene derivative interferes with seemingly invincible cancer stem cells

By - February 25, 2015 2 Pictures
While well known for its unique electromechanical properties, graphene may also prove key in preventing cancer tumor recurrence. A drawback of traditional cancer treatment with radiation and chemotherapy is that the primary developmental source of future tumors is not eradicated. Cancer stem cells, or CSCs, can survive treatment and give rise to recurring tumors, metatasis, and drug resistance after repeated treatments. Researchers from the University of Manchester and the University of Calabria have discovered that graphene oxides targets and neutralize CSCs in a manner that is not yet fully understood. Read More

Flexible graphene-based LED clears the way for flexible displays

By - February 2, 2015 2 Pictures
Researchers from the University of Manchester and University of Sheffield have developed a new prototype semi-transparent, graphene-based LED device that could form the basis of flexible screens for use in the next-generation of mobile phones, tablets and televisions. The incredibly thin display was created using sandwiched "heterostructures", is only 10-40 atoms thick and emits a sheet of light across its entire surface. Read More

Graphene could find use in lightweight ballistic body armor

By - December 1, 2014 2 Pictures
While graphene is already known for being the world's strongest material, most studies have focused on its tensile strength – that's the maximum stress that it can withstand while being pulled or stretched, before failing. According to studies conducted at Houston's Rice University, however, its ability to absorb sudden impacts hadn't previously been thoroughly explored. As it turns out, the material is 10 times better than steel at dissipating kinetic energy. That could make it an excellent choice for lightweight ballistic body armor. Read More

Zap&Go portable charger fuels up in just 5 minutes

By - October 14, 2014 4 Pictures
An Oxford-based startup has turned to crowdfunding to help develop Zap&Go, a phone charger with an emphasis on speed and portability. Thanks to a graphene supercapacitor and an ad-hoc power supply, the device will reportedly charge to its 1,500-mAh capacity – enough to fully charge an iPhone 5s – in only five minutes and promises to be a much more practical solution than current alternatives, particularly when traveling.

"Nanograss" boosts the efficiency of organic solar cells

By - October 13, 2014 4 Pictures
Researchers at the University of Massachusetts Amherst, Stanford University and the Dresden University of Technology have developed a long sought-after nanostructure that can significantly increase the efficiency of organic solar cells. Their "nanograss," a dense array of vertical nanopillars, can capture photons at a very high efficiency and could also lead to cheaper and more advanced 3D transistors, photodetectors and charge storage devices.
