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.”

Researchers turn waste byproduct asphaltene into graphene

Researchers from Rice University, University of Calgary, South Dakota School of Mines and Technology and University of Washington have managed to turn a waste material called asphaltene (a byproduct of crude oil production) into graphene.

Rice University's Muhammad Rahman, an assistant research professor of materials science and nanoengineering, is employing Rice’s unique flash Joule heating process to convert asphaltenes instantly into turbostratic (loosely aligned) graphene and mix it into composites for thermal, anti-corrosion and 3D-printing applications. The process makes good use of material otherwise burned for reuse as fuel or discarded into tailing ponds and landfills. Using at least some of the world’s reserve of more than 1 trillion barrels of asphaltene as a feedstock for graphene would be good for the environment as well.

Nanotech Energy demonstrates durability of its graphene-enhanced batteries in new abuse test

Nanotech Energy recently reported a demonstration of its graphene-powered batteries' non-flammable qualities in a new abuse test. A Nanotech Graphene-Powered Lithium-Ion Battery 18650 cell was shot by a 4.5BRA bullet at a speed of 2,917 feet per second. Despite the considerable force of impact, the battery did not catch fire and even still held a charge.

In contrast, the company said that a rival commercial battery 18650 cell shot by a 4.5BRA bullet at a speed of 2,915 feet per second immediately burst into flames and no longer held a charge.
