Kansas U team takes an explosive approach to graphene manufacturing

Jan 26, 2017

A team of researchers at Kansas State University has discovered a way to mass-produce graphene with three ingredients: hydrocarbon gas, oxygen and a spark plug. The technique involves filling a chamber with acetylene or ethylene gas and oxygen and using a vehicle spark plug to create a contained detonation - all that's left then, according to the team, is collecting the graphene that forms afterward.

The researchers state that this is a viable process to make graphene; they explain that the process has many positive properties, like economic feasibility, the possibility for large-scale production and the lack of hazardous chemicals. What might be the best property of all is that the energy required to make a gram of graphene through this process is much lower than other processes.

Nanomedical Diagnostics starts shipping its graphene-based sensors, explains its technology and business to Graphene-Info

Dec 04, 2016

San Diego-based Nanomedical Diagnostics, established in late 2013 to develop cutting-edge diagnostics equipment, recently started shipping its graphene-based sensors and the AGILE R100 system which allows for real-time detection of small molecules - with no lower size limit. Nanomedical's graphene-based sensors enable faster sample processing, greater accuracy, portability and cost savings.

Huawei introduces new high-temperature Li-Ion batteries that use graphene to reduce operation temperature and increase the lifetime

Nov 30, 2016

Huawei unveiled a new Li-Ion battery that can remain functional at higher temperature (60° degrees as opposed to the existing 50° limit) and offers a longer operation time - double than what can be achieved with previous batteries.

To achieve this breakthrough, Huawei incorporated several new technologies - including an anti-decomposition additives in the electrolyte, chemically stabilized single crystal cathodes - and graphene to facilitate heat dissipation. Huawei says that the graphene reduces the battery's operating temperature by 5 degrees.

A visit to the NPL and recent research updates

Nov 28, 2016

A few weeks ago we visited the National Physical Laboratory (NPL) in Teddington, UK. We were given a tour of the facilities, the graphene labs and met with several key researchers and the business development team. The NPL is the UK's national measurement institute, and is a world-leading measurement standards institute - and certainly one of the leading institutes in the field of graphene metrology.

The NPL's facilities are very impressive, it's a beautiful campus set in the lovely town of Teddington - about half an hour by train from central London. The research facilities and laboratories were very well equipped and we pleasantly surprised to find out how nice and hospitable the researchers were. It was great to see so many graphene related activities at the NPL.
