July 2014The Graphene Council News
This latest publication of the Graphene Council Newsletter marks our second edition—an anniversary of sorts. This year also marks the tenth anniversary of the publication in the journal Science of Andre Geim and Kostya Novoselov describing their successful extraction of single-atom-thick crystallites from bulk graphite.
The March of 2-D Materials Across the Flatlands
We hope you enjoy being a part of The Graphene Council community as we continue to bring you original interviews and analysis from the global graphene community. More from the Editor . . .
Determining how toxic and dangerous nanomaterials are to our health and environment has been a hot topic for more than 10 years now.
In an original interview on nanomaterials and toxicity, we have a Q&A with Dr. Andrew Maynard, the National Science Foundation’s International Chair of Environmental Health Sciences and the Director for the University of Michigan’s Risk Science Center.

After a decade of characterizing graphene's properties, attention is turning towards manufacturing it cheaply and effectively
One of the hurdles facing nanomaterials to achieve their promised impact is manufacturing them at a cost that would make them competitive with the materials they are intended to replace.
Graphene is not the only 2-D material out there but they aren't all competitors, some are allies. The field of 2-D materials (sometimes referred to as the flatlands) has been growing with new materials being added to the mix fairly regularly.
The early work with these materials has indicated that they all have different strengths and weaknesses. Some look promising for logic and memory chips while others look best suited for computing with light. Others are best when combined with another 2-D material.

The optical properties of graphene come to it naturally and researchers don't need a band gap to exploit them.
Early research focus with graphene was aimed at applying it to electronics. However, many experts believe that the real opportunity for graphene may be in the area of photonics and optoelectronics.
Graphene's contribution to the advancement of supercapacitors may not be what people expected, but it still may be pretty significant.
Not too long after research labs around the world first started experimenting with graphene, one of the early ideas for an application was to see if it could replace the activated carbon used in the electrodes of supercapacitors.
Graphene Poised to Transform Li-ion Batteries
Meeting a need of high capacity and ease of manufacturing, decorated graphene may hold the key to the next generation of Li-ion batteries
For generations the lithium ion (Li-ion) battery anode was pretty much ignored as far as technological development. Its material makeup stayed the same during all that time, and graphite was the electrode material that was used.Read more . . . Filling a critical void in the value-chain for Graphene commercialisation
Producers and end-users alike require several key components in the value chain to be met before successful and sustainable trade in a material can occur. Read more . . .
