Cambridge spin-out starts producing graphene at commercial scale • University of Cambridge
<p>Graphene’s remarkable properties – stronger than steel, more conductive than copper, highly flexible and transparent – make it ideal for a range of applications. However, its widespread commercial application in electronic devices has been held back by the difficulties associated with producing it at high quality and at high volume. The conventional way of making large-area graphene involves using copper as a catalyst which contaminates the graphene, making it unsuitable for electronic applications.

Professor Sir Colin Humphreys from the Centre for Gallium Nitride in Cambridge’s Department of Materials Science and Metallurgy, along with his former postdoctoral researchers Dr Simon Thomas and Dr Ivor Guiney, developed a new way to make large-area graphene in 2015.

Using their method, the researchers were able form high-quality graphene wafers up to eight inches in diameter, beating not only other university research groups worldwide, but also companies like IBM, Intel and Samsung.

The three researchers spun out Paragraf in early 2018. Thomas is currently the company’s CEO and Guiney is its Chief Technology Officer, while Humphreys, who has recently moved to Queen Mary University of London, serves as Chair.

Paragraf has received £2.9m in funding to support the development of its first commercial products and moved into premises in February 2018.</p>

Graphene – An Open Source Blockchain | OCI
Blockchains are useful in the way databases are, storing data and allowing its manipulation, but with a twist. Data is stored in a blockchain as an immutable record of transactions. Integrity of the chain is maintained through the use of an algorithm, which verifiably links each new block to the history of blocks that precede it back to the origin of the chain.

Graphene, an Open Source, mostly C++, blockchain implementation was originally developed as the foundation of Bitshares, a cryptocurrency exchange marketplace.

The Graphene source is available in numerous variations, as it has been forked and adapted many times. The original release is managed by an organization known as Cryptonomex.
