UK researchers demonstrate a viable graphene-based OLED encapsulation solution

OLED displays are very sensitive to oxygen and moisture, and the need to protect the displays is one of the major challenges of this next-generation display technology. First generation OLED displays were protected with a glass barrier, but glass is not easily flexible and so cannot be used in flexible OLEDs. Flexible OLEDs are today encapsulation with a thin-film encapsulation layer made from both organic and in-organic materials, and companies are searching for better OLED encapsulation technologies.

Physicists have breakthrough on brittle smartphone screens

Scientists at the University of Sussex may have found a solution to the long-standing problem of brittle smartphone screens.

Professor Alan Dalton and his team have developed a new way to make smartphone touch screens that are cheaper, less brittle, and more environmentally friendly. On top of that, the new approach also promises devices that use less energy, are more responsive, and do not tarnish in the air.

New Graphene Sensor is Less Noisy, More Sensitive

Graphene’s ability to detect a variety of chemical and biological molecules would seem to make it a perfect match for sensors. But because graphene is a conductor and lacks an inherent band gap, it’s hard to fashion the material into a transistor that can be turned on and off.

In order to make a sensor out of graphene, you need to use multiple layers of the material, which leads to high levels of electronic noise and reduces its effectiveness.

FLAG-ERA Recommends new Graphene Projects

FLAG-ERA has announced the outcome of its second Joint Transnational Call for projects in synergy with the Graphene Flagship and the Human Brain Project (FLAG-ERA JTC 2017). Relating to the Graphene Flagship, in total 17 basic and applied research projects have been recommended for funding to the national research funding organisations by the FLAG-ERA JTC 2017 Call Steering Committee. The actual funding of the projects depends on the successful completion of the final funding decisions and contract negotiations at the national level.

Graphene and liquid salt to double the energy storage of supercapacitors

Researchers at the University of Waterloo managed to significantly improve supercapacitors, by combining graphene with an oily liquid salt in the supercapacitors’ electrodes.

The researchers explained that the liquid salt serves as a spacer to separate the thin graphene sheets, preventing them from stacking. That dramatically increases their exposed surface area, a key to maximizing energy-storage capacity. At the same time, the liquid salt doubles as the electrolyte needed to actually store electrical charge, minimizing the size and weight of the supercapacitor.

Different Faces of Graphene: How New Research Can Vary So Much

Graphene, known worldwide as a potential wonder material, is asserting its dominance across nanotechnology, materials science, chemistry and physics fields. New research is being published all the time, be it in small open-access journals or high impact paywall journals. Industry is advancing at a fast pace and is being governed by organizations such as the National Graphene Association (NGA, Mississippi, USA) and the National Graphene Institute (NGI, Manchester, UK).

UAE’s Masdar funds UK centre to investigate ‘wonder material’

A new research centre at the University of Manchester in England aimed at marketing products and technologies made from a “wonder material” known as graphene will be called The Masdar Building.

Abu Dhabi Future Energy Company, better known as Masdar, is the principal funder of the purpose-built Graphene Engineering Innovation Centre (GEIC), which held its formal topping out ceremony.
