New model describes geometric features of carbon networks and their influence on the material's properties

Scientists at Tohoku University and colleagues in Japan have developed a mathematical model that abstracts the key effects of changes to the geometries of carbon material and predicts its unique properties.

Scientists generally use mathematical models to predict the properties that might emerge when a material is changed in certain ways. Changing the geometry of three-dimensional (3D) graphene, which is made of networks of carbon atoms, by adding chemicals or introducing topological defects, can improve its catalytic properties, for example. But it has been difficult for scientists to understand why this happens exactly.

Researchers develop a new method for quick and efficient synthesis of nanographenes

A research team at Nagoya University in Japan has developed a new technique for synthesizing nanographenes, remarkable materials with a vast number of potential structures that can even exhibit electric and magnetic characteristics beyond those of graphene.

Since each nanographene exhibits different physical characteristics, the key to applied nanographene study is to determine the relationship between the structure and characteristics of as many nanographenes as possible.

Researchers examine 'Kagome' graphene and report promising results

Researchers from the Department of Physics and the Swiss Nanoscience Institute at the University of Basel, working in collaboration with the University of Bern, have recently produced and studied a compound referred to as "kagome graphene", that consists of a regular pattern of hexagons and equilateral triangles that surround one another. The name kagome comes from the old Japanese art of kagome weaving, in which baskets are woven in the same pattern.

Two-dimensional (2D) materials have a huge potential for providing devices with much smaller size and extended functionalities with respect to what can be achieved with today's silicon technologies. But to exploit this potential, it is vital to be able to integrate 2D materials into semiconductor manufacturing lines - a notoriously difficult step. This new technique could be a step in the right direction as far as solving this problem is concerned.
