Versarien launches graphene-based superparamagnetic material

Versarien has announced the launch of a new hybrid nanomaterial that has superparamagnetic properties, which can be used across a range of applications, like defense and healthcare. The new material combines graphene with both iron oxide and manganese oxide nanoparticles and its development was led by Versarien's 62% owned subsidiary, Gnanomat.

The superparamagnetic material combines graphene with both iron oxide and manganese oxide nanoparticles that provide the material with magnetic properties. In return, graphene provides electrical conductivity to these electrically insulating metal oxides. Magnetic nanocomposites can readily respond to external magnetic fields which allow them to be manipulated. Potential applications of the material include the treatment of wastewater whereby pollutants are adsorbed onto the graphene surface. The material could also lends be used in biomedical and biotechnology applications, or defense applications requiring the shielding of electromagnetic fields. Magnetic manipulation could allow the recovery and recycling of the graphene, something that could not be done with normal graphene compounds.

Researchers succeed in synthesizing graphyne

Researchers at the University of Colorado Boulder and Qingdao University of Science and Technology have managed to synthesize an illusive form of carbon called graphyne. Graphyne has long been of interest to scientists because of its similarities to graphene. However, despite decades of work and theorizing, only a few fragments have ever been created before now.

Japan launches a $8.5 million project to study 2.5D materials

Japan's Ministry of Education, Culture, Sports, Science and Technology has launched a collaborative project to develop 2.5D materials. The project, titled "Science of 2.5 Dimensional Materials: Paradigm Shift of Materials Science Toward Future Social Innovation" includes 40 researchers in Japan, led by Prof. Ago Hiroki at Kyushu University.

2.5D materials are made by stacking different 2D materials artificially by using advanced transfer techniques. These new materials are not limited by lattice constant or composition, and it is possible to control the material layers, and their stacking angle. These new materials could unlock new breakthroughs in materials science.

Researchers succeed in synthesizing single layers of hexagonal boron nitride on graphene

A research team led by the University of Michigan has developed a reliable, scalable method for growing single layers of hexagonal boron nitride on graphene.

Graphene-hBN structures can power LEDs that generate deep-UV light, which is impossible in today's LEDs, said Zetian Mi, U-M professor of electrical engineering and computer science and a corresponding author of the study. Deep-UV LEDs could drive smaller size and greater efficiency in a variety of devices including lasers and air purifiers.
