2D-EPL offers a chance to test graphene-based sensors on large scale

The 2D Experimental Pilot Line (2D-EPL), that originated from the Graphene Flagship, recently launched its first customizable wafer run.

As one of five multi-project wafer (MPW) runs, this first phase is targeting sensor applications. Companies, universities and research institutes can include their designs as dies on joint wafers, to test their ideas for devices on a larger scale at relatively low costs. The first 2D-EPL MPW run opened in February and the call closes on 30 June 2022. The manufacturing stage of the MPW run will take place between 1 September and 31 October 2022.

Researchers wrapped droplets in graphene for better sensors, microchips and batteries

Researchers from the University of Sussex, the University of Brighton and CNRS have developed a way to wrap emulsion droplets with graphene and other 2D materials by reducing the coatings down to atomically-thin nanosheet layers. The team said this could ‘significantly advance’ the new technology area of liquid electronics, enhancing the functionality and sustainability of potential applications in printed electronics, wearable health monitors and even batteries.

The scientists were able to create electrically-conducting liquid emulsions that are the lowest-loading graphene networks ever reported – just 0.001 vol%. This means that the subsequent liquid electronic technology will be both cheaper and more sustainable because it will require less graphene or other 2D nanosheets coating the droplets.

UK-based Paragraf raises $60 million in its latest financing round

UK-based graphene developer Paragraf has raised $60 million from the UK's Future Fund, the CIA-backed In-Q-Tel and other investors. The funds will be used to accelerate the company's device development, production and market launch.

Paragraf's newly launched Hall Effect sensors based on graphene image

Paragraf produces its own CVD graphene materials, which it then uses to create devices for the sensor, energy and semiconductor markets. The company introduced its first product, a graphene-based hall-effect sensor back in 2020, and it has recently concluded a study to test the deployment of graphene as an OLED electrode material.

Graphene assists in observing the elusive Schwinger effect

Researchers at The University of Manchester, MIT and other international collaborators have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team - based at the National Graphene Institute - succeeded in producing particle-antiparticle pairs from a vacuum.

A vacuum is assumed to be completely empty space, without any matter or elementary particles. However, it was predicted by Nobel laureate Julian Schwinger 70 years ago that intense electric or magnetic fields can break down the vacuum and spontaneously create elementary particles.
