Korea-based ETRI develops OLED display with graphene transparent electrodes

Apr 11, 2017

Researchers from the Korea-based ETRI (Electronics and Telecommunications Research Institute) have used graphene transparent electrodes to create an OLED display, 370mm x 470mm in size.

The ETRI team designed a process that can pattern a graphene-made transparent electrode in accurate size on a glass substrate. The researchers replaced indium tin oxide used for current commercial applications, that is a rare metal known for being brittle.

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.
