The use of graphene in the growing field known as plasmonics—in which the waves of electrons known as surface plasmons that are generated when photons strike a metallic structure—has been transforming the world of photonics and optoelectronics, enabling the possibility of much smaller devices operated by photons rather than electrons.
Scientists at Rutgers University-New Brunswick have found a way to control the electrons in graphene, paving the way for the ultra-fast transport of electrons with low loss of energy in novel systems. “This shows we can electrically control the electrons in graphene,” said a professor in Rutgers’ Department of Physics and Astronomy. “In the past, we couldn’t do it. This is the reason people thought that one could not make devices like transistors that require switching with graphene, because their electrons run wild.”
Adding a specialized form of graphene to gas sensors can imbue these machines with significantly heightened sensitivity compared to traditional counterparts.
Engineers from the University of Nebraska-Lincoln, University of Illinois at Urbana-Champaign, and Russia’s Saratov State Technical University created a new of type of nano-ribbon derived from the 2D honeycomb of carbon atoms, which stand vertically rather than lying flat on a surface.
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.
