Graphene is extremely strong for its weight, it's electrically and thermally conductive, and it's chemically stable ... but it isn't magnetic. Now, however, a team from the University of California, Riverside has succeeded in making it so. The resulting magnetized graphene could have a wide range of applications, including use in "spintronic" computer chips. Read More
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
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.

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.

With its incredible strength, chemical stability, high thermal conductivity and low electrical resistance, it's no wonder that graphene is finding more and more uses. Soon, however, it may be facing some competition from molybdenum di-sulphide – a thin metallic film that can emit light. Read More
Flexible displays are the new must-have element in the race for the next generation of high-tech electronic devices. A new prototype display created with graphene promises to provide a more efficient, printable alternative to current construction methods with the added benefit of perhaps one day creating a true, fully-folding display.

A new prototype light detector uses graphene's light-absorbing properties to see in a broad band of light wavelengths that includes terahertz waves. These fall between the microwave and infrared bands, thereby making it possible to look just beneath the surface of opaque objects such as skin and plastic. Read More
Graphene is a cutting-edge wonder material, used in applications ranging from solar cells to supercapacitors. Rubber bands, on the other hand ... well, they're not so high-tech. By combining the one with the other, however, scientists have created ultra-cheap body motion sensors that could make a big difference in the field of health care. Read More
Using waste hemp fibers as the starting material, researchers at the University of Alberta in Canada have developed a high-performance electrode material for supercapacitors at one thousandth the cost of the more commonly used graphene. The advance could lead to supercapacitors that are both cheaper and able to operate under harsh environmental conditions. Read More
For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.
