Graphene Flagship researchers reviewed the current research into the safety of graphene and related materials looking at both human health and environmental impact.

New printing technique and materials could be used to develop intelligent materials and self-adaptive infrastructures and transducers.

Experimental proof of a decades-old prediction opens a pathway to recreate possible conditions of the early universe here on earth.

A new wave of semiconductors that can be painted on is on the horizon. It bears the promise of revolutionizing lighting all over again and of transforming solar energy. Ornate quantum particle action, revealed here, that drives the new material's properties defies the workings of established semiconductors.

The absorption of light in semiconductor crystals without inversion symmetry can generate electric currents. Researchers at the Max-Born-Institute have now generated directed currents at terahertz (THz) frequencies, much higher than the clock rates of current electronics. They show that electronic charge transfer between neighboring atoms in the crystal lattice represents the underlying mechanism.

Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just some of the technologies that could benefit from their new discovery, which deals with 'double-doped' polymers.

In a paper published today in Nature Communications, Vardeny, along with Jingying Wang, Dali Sun (now at North Carolina State University) and colleagues present two devices built using perovskite to demonstrate the material's potential in spintronic systems. Its properties, Vardeny says, bring the dream of a spintronic transistor one step closer to reality.

For the first time, researchers used benzene -- a common hydrocarbon -- to create a novel kind of molecular nanotube, which could lead to new nanocarbon-based semiconductor applications.

UNSW scientists have shown that their pioneering single atom technology can be adapted to building 3D silicon quantum chips -- with precise interlayer alignment and highly accurate measurement of spin states. The 3D architecture is considered a major step in the development of a blueprint to build a large-scale quantum computer.
