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.

"The whole audience, the whole field, is really excited that this long-standing problem, or this imaginary material, is finally getting realized," said Yiming Hu, lead author on the paper.

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.

Researchers detect evidence of strong electron correlation in a trilayer graphene/hBN moiré superlattice

Researchers from MIT, Harvard University, University of California at Berkeley, Lawrence Berkeley National Laboratory, China's Shanghai Jiao Tong and Fudan Universities and Japan's National Institute for Materials Science have taken a significant step toward understanding electron correlations.

In their new study, the researchers revealed direct evidence of electron correlations in a two-dimensional material called ABC trilayer graphene. This material has previously been shown to switch from a metal to an insulator to a superconductor.

MIT researchers manage to create a 2D polymer material for the first time

Researchers from MIT created a new 2D material, called 2DPA-1, which is the world's first 2D polymer. Until now, it was actually believed to be impossible to induce polymers into a 2D sheet.

To create the material, the researchers used a novel polymerization process, that was used to generate a two-dimensional sheet called a polyaramide. For the monomer building blocks of the material, they use a compound called melamine, which contains a ring of carbon and nitrogen atoms. Under the right conditions, these monomers can grow in two dimensions, forming disks. These disks stack on top of each other, held together by hydrogen bonds between the layers, which make the structure very stable and strong.
