Researchers develop graphene-enabled single fiber actuator inspired by human muscles

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) and Pusan National University in South Korea recently developed a graphene-enhanced  actuator for robotics applications, that is inspired by mammalian skeletal and muscle structures. The new actuator is based on soft fibers with strong contractive actuation properties.

The team explained that they based their work on liquid crystal elastomer (LCE) actuators, promising soft actuator materials with unusually large reversible dimensional change (shrink/relaxation) upon actuation, which is rarely observed in other kinds of actuator materials but highly significant to ideally mimic natural skeletal muscle behavior. Many actuators developed in the past are based on LCE materials, a class of polymers that can rapidly change shape in response to environmental stimuli. Despite their shape-morphing advantages, LCE polymers are known to be associated with the relatively poor mechanical properties and weak actuation behavior. To overcome this limitation, the researchers incorporated graphene fillers within the LCE actuators. In addition to enhancing their mechanical properties, the team expected the graphene fillers to enable light-driven, rapid and remotely controllable actuation, owing to the photothermal conversion capability of graphene.

Researchers study the effects of defects on electron emission of Graphene electrodes

Researchers from the Chinese Academy of Sciences, the University of Science and Technology of China and North China University of Water Resources and Electric Power have studied the effects of irradiation defects on the work function of graphene electrodes in thermionic energy converters (TECs) and found that the generation of defects in graphene through irradiation would increase the work function and reduce the electron emission capacity.

Graphene has great potential as an electrode coating material for TECs of the microreactor, which can significantly improve the electron emission ability of electrode. Electrode materials will be exposed to irradiation by high-energy particles during TECs use. Previous studies have shown that the types of defects induced by irradiation in graphene are mainly Stone-Wales defects, doping defects, and carbon vacancies. The appearance of defects will affect the adsorption properties of alkali and alkaline earth metals on the graphene surface in the electrode gap, and then change the electron emission properties of the graphene coating.

Silca launches new bicycle chain lubricant, made with graphene by Versarien

Silca, producer of bicycle accessories, has launched a graphene-based chain lubricant, Hot Wax X. Silca claims it ‘runs roughly 0.5 watts faster’ than their original Secret Chain Blend hot-melt wax, and that it can extend the chain life to 30,000km. The new lubricant comes at quite a high price of £220 per 300g tin. 

Silca previously made waves with its Secret Blend Hot Chain Wax, which gained the reputation of 'the fastest lubricant in the world'. Now, Silca found Nanene (by Versarien, which owns the Nanene brand), a commercial type of graphene, to further improve its product.

Researchers achieve water-enabled electricity generation through highly oriented graphene oxide nanochannels

Researchers from China's Tsinghua University have constructed highly aligned graphene oxide (GO) nanochannels for sustainable energy production using a freeze-casting process. The new method could address an issue that impedes the generation of electricity from natural water flow through engineered nanochannels, which could become a viable way to cater to the fast-growing renewable power needs.

Large-scale nanochannel integration and the multi-parameter coupling restrictive influence on electric generation currently remain big challenges for macroscale applications, but this novel design encourages spontaneous absorption and directed transfer of water within the nanochannels to generate clean electricity.

Skoltech team patents method for defect-free graphene for flexible transparent electronics

Skoltech researchers have patented a method that enables producing arbitrarily shaped functional graphene components on a transparent substrate with 100-nanometer resolution, which could be especially suited for flexible and transparent electronics. The new approach reportedly helps avoid defects that arise during graphene transfer between substrates and strongly affect the material’s quality.

“Flexible and transparent electronics is typically associated with wearable biosensors that monitor vital signs, such as heart rate, breathing, and blood oxygenation, and relay them to a smartphone or fitness band,” Skoltech PhD student Aleksei Shiverskii, one of the inventors, said. “An affordable and efficient technology that at first may seem impractical soon becomes a ubiquitous and indispensable appliance, like a bluetooth electric kettle or a wifi vacuum cleaner. I believe that someday flexible and transparent electronics will become a fixture, too.”
