Graphene and other carbon nanomaterials can replace scarce metals

Graphene and other carbon nanomaterials can replace scarce metals

Press Releases   •   Sep 19, 2017 07:00 BST

Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become “conflict minerals”. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.

By combining graphene with another two-dimensional material, researchers at Chalmers University of Technology have created a prototype of a transistor-like device for future computers, based on what is known as spintronics. The discovery is published in the scientific journal Nature Communications.

Heat dissipation in electronics and optoelectronics is a severe bottleneck in the further development of systems in these fields. To come to grips with this serious issue, researchers at Chalmers University of Technology have developed an efficient way of cooling electronics by using functionalized graphene nanoflakes. The results are published today in Nature Communications.

​Researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film has a thermal conductivity capacity that is four times that of copper. Moreover, the graphene film is attachable to electronic components made of silicon.
