Desirable properties including increased electrical conductivity, improved mechanical properties, or magnetism for memory storage or information processing may be possible because of a theoretical method to control grain boundaries in two-dimensional materials, according to Penn State materials scientists.
Pinning DNA-sized ribbons of carbon to a gas sensor can boost its sensitivity far better than any other known carbon material, says a new study from the University of Nebraska-Lincoln.
The Greece-based IntelenAn has announced that a working model of a graphene-enhanced lithium ion “smart” battery for households will be ready in February 2018.
The company’s CEO mentioned that two Greek firms are currently collaborating to develop the first model of a lithium ion ‘smart’ battery for commercial use. He noted his team is working with researchers at the Demokritos research center, who have set up a specialized company and developed a new lithium ion electrode enriched with graphene.
An effective synthesis strategy via a flash-freezing and freeze-dry approach is presented, to synthesis 3D GO structures that exhibit fully accessible hierarchical porous networks for supercapacitor applications.
Researchers at Clemson University in the U.S have shown that replacing lithium with aluminum and graphene may be key for next-gen batteries.
Researchers from Italy’s University of Florence have found that graphene oxide could significantly improve the efficiency of perovskite solar cells. The researchers have shown how the introduction of graphene and graphene oxide doped with lithium atoms (GO-Li) into a perovskite-based cell may increase its conversion efficiency, as both the carrier recombination dynamics and the defect density of the perovskite are considerably improved.
Mimos, the Malaysian R&D center under the Ministry of Science, Technology and Innovation (MOSTI), recently signed a collaborative research and development agreement with Universiti Pendidikan Sultan Idris (UPSI) to develop graphene electronic technology to enhance both their competitive advantage in the technology and applications, especially in advanced materials for electronic devices.
The China-based Shanghai Kyorene New Material Technology recently unveiled a graphene-based flame-retardant fabric during the Textile & Yarn Expo in Shanghai. The fabric seems to be extremely resistant to flames, and no damage appears even when it is directly touched with a burning lighter. It is also said to posses anti ultra-violet and anti-static properties. It can be used for firefighting purposes as well as furniture and other domestic uses.
The world’s first ISO (International Organisation for Standardization) graphene standard has been published. The standard will provide consistency across the emerging world-wide graphene industry and accelerate the 2D material’s commercial exploitation.
The new international standard, led by the National Physical Laboratory (NPL), defines the terminology used to describe the many different forms of graphene and related 2D materials, supporting companies in the testing and validation of the ‘wonder material’. This will provide clarity among manufacturers, suppliers, NGOs and academia, helping to unlock new applications, drive down manufacturing costs and open up industrial-scale use of graphene for applications from next-generation computer chips to smart sensors in clothing.
An international research team at Swansea University in the UK recently received an international award for developing a graphene biosensor-based diagnostic test for ovarian cancer that is said to offer quicker and more accurate results in a less expensive, as well as portable way.
The team received the i3S-Hovione Capital Health Innovation Prize, an international award aimed at distinguishing innovative ideas in the health sector, for developing a device — called ‘MagCyte’ — that can diagnose ovarian cancer in a couple of minutes using only a single drop of blood. The portable technology is different from the tests currently used in hospitals and allows for increased flexibility when monitoring patients, even if they have already been diagnosed with ovarian cancer. According to the development team, the innovative technology allows for the diagnosis of ovarian cancer up to four years before it can be diagnosed through the technology currently available.
