Graphene electronic paper developed in China

The world’s first graphene-based electronic paper for use in both hard and flexible displays for electronic devices has been developed in China.

Electronic paper display company Guangzhou OED Technologies announced it has developed the graphene-based e-paper, which it described as being more pliable and having higher light transmittance than existing types of e-paper.

As a result, graphene-based displays would be brighter but also cheaper, as graphene is based on the abundant element carbon, the firm said. Conventional e-paper is made of the rather costly rare metal indium.

This Bendable Smartphone Has A Screen Made of Graphene

A video of a fully bendable smartphone with a graphene touch display debuts at a Chinese trade show.

A Chinese company just showed off a fully bendable smartphone with a graphene screen during a trade show at Nanping International Conventional Center in Chongqing. Videos of the incredibly flexible phone are making the rounds, and no wonder, as it looks rather impressive.

It isn’t yet known which company developed the bendable smartphone, and very few details have emerged about it. What we do know is that it weighs 200g, the smartphone can be worn around the wrist, and the screen is fully touch enabled.

Scientists have finally made a substance that’s even stronger than graphene

Much like in comic books, scientists are on an endless quest to discover or create the strongest, most durable substance possible. Theories about how to go about that have long circulated, but nobody has been able to overcome the challenge—until now. A team of Austrian researchers has finally worked out a way to stabilize what they are calling the strongest of all known materials, an exotic form of carbon called carbyne.

Graphene is both transparent and opaque to radiation

A microchip that filters out unwanted radiation with the help of graphene has been developed by scientists from the EPFL and tested by researchers of the University of Geneva (UNIGE). The invention could be used in future devices to transmit wireless data ten times faster.

EPFL and UNIGE scientists have developed a using graphene that could help wireless telecommunications share data at a rate that is ten times faster than currently possible. The results are published today in Nature Communications.

“Our graphene based microchip is an essential building block for faster wireless telecommunications in frequency bands that current mobile devices cannot access,” says EPFL scientist Michele Tamagnone.
