Scientists Find Stronger 3-D Material that Behaves Like Graphene

The next revolution in electronics industry may begin earlier than expected. Despite that the Graphene is a great material, begin a 2D material makes it difficult to be used in industry, so having cadmium arsenide may overcome this obstacle and we might see them sooner than expected.

Scientists have discovered a material that has the same extraordinary electronic properties as 2-D graphene, but in a sturdy 3-D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes.

The material, cadmium arsenide, is being explored independently by three groups, one of which includes researchers at the University of Oxford, SLAC, Stanford and Lawrence Berkeley National Laboratory who described their results in a paper published May 25 in Nature Materials.

PaperFold: Foldable Smartphone Shows Shape

PaperFold is a shape-changing smartphone allows users to fold open up to three flexible electrophoretic displays to provide extra screen real estate when needed. Displays are detachable such that users can fold the device into various shapes that can range from an ultra notebook shape to a foldout map.

“In PaperFold, each display tile can act independently or as part of a single system,” says Dr. Vertegaal, a professor in the School of Computing and Director of the Human Media Lab at Queen’s. “It allows multiple device form factors, providing support for mobile tasks that require large screen real estate or keyboards on demand, while retaining an ultra-compact, ultra-thin and lightweight form factor.”
