Graphene oxide enables a material that is both hard and self-healing
Researchers from the Chinese Harbin Institute of Technology have developed an intriguing material that combines a soft, self-healing polymer with a tough layer of graphene oxide and could one day form the basis of ultra-tough scratch resistant coatings.
Graphene enables new radiation detector
Researchers at Chalmers University of Technology and the Beijing University of Technology have exploited graphene’s thermoelectric properties to create a new kind of radiation detector. Classified as a bolometer, the new device has a fast response time and, unlike most other bolometers, works over a wide range of temperatures. With a simple design and relatively […]
Clemson team uses graphene to pave the way towards wireless energy generation
Researchers from Clemson’s Nanomaterials Institute (CNI) have made progress towards their goal to produce wireless power using triboelectricity – a green energy source invented by the CNI In March 2017. The simple triboelectric nanogenerator, or U-TENG, is a small device made simply of plastic and tape that generates electricity from motion and vibrations. When the […]
Researchers demonstrate graphene as a source of high-speed light pulses
One of the key requirements of future optical communications technologies is a nanoscale light source capable of emitting ultrafast light pulses. In a new study, researchers have shown that graphene may be an ideal candidate for such a light source, by demonstrating graphene-based devices that emit light pulses with a bandwidth of up to 10 […]
Live Imaging of Label-Free Graphene Oxide Reveals Critical Factors Causing Oxidative-Stress-Mediated Cellular Responses
The interest in graphene and its translation into commercial products has been expanding at a high pace. Based on previously described pulmonary safety concerns for carbon nanomaterials, there is a great need to define parameters guiding interactions between graphene-based materials and the pulmonary system.
ICL team combines graphene and silk to create improved armor
Imperial College London researchers aim to reduce the weight of body armor by combining silk with graphene. The team hypothesized that by improving on the Kevlar layer, they could reduce the size of the ceramic outer layer, making the vest much more wearable. They initially looked at spider silk (as it is known to be […]
Skin-inspired graphene oxide based coating that’s as hard as teeth and can heal itself
Self-healing smart coatings could someday make scratches on cell phones a thing of the past. But researchers often have to compromise between strength and the ability to self-repair when developing these materials.
Keeping us charged and on the road: addressing energy storage
In the run-up to a national conference focusing on how new materials can help drive the e-car revolution entitled Automotive Advanced Materials: 2D or not 2D? Richard Fields, a Research Associate at the National Graphene Institute, a world-leading facility that supports Royce’s 2D materials research, discusses the challenges for the future of electric transportation and […]
Scientists found that zero gravity graphene promises success in space
In a progression of examinations directed a month ago, Cambridge analysts experiencedweightlessness testing graphene’s application in space. Acting as a major aspect of a joint effort between the Graphene Flagship and the European Space Agency, scientists from the Cambridge Graphene Center tried graphene in microgravity conditions out of the blue while on board an illustrative flight […]
