Stacking on the graphene

14-Feb-2018

Researchers in Japan have found a way to form two materials, each made of three layers of graphene. Each material's graphene is stacked differently and has unique electrical properties. Their work has implications for the development of novel electronic devices, such as photo sensors that convert ...

Water-Soluble Warped Nanographene

Synthesis of a water-soluble warped nanographene and its application for photo-induced cell death

13-Feb-2018

Graphene and its nano-sized little sibling, nanographene, are well known for their remarkable photoelectronic properties. However, biomedical applications are hampered by the insolubility of the materials, especially in water. A Japanese team of scientists has now introduced substituted “warped ...

Moving beyond graphene

Getting closer to optimize 2D materials

07-Feb-2018

Chemists are working to synthesize the next generation of super materials for high-performance electronics, solar cells, photodetectors and quantum computers. While they have made progress with compound materials, they have not yet succeeded in developing unaltered or "freestanding" materials for ...

Smaller laser - more power

25-Jan-2018

An international team of scientists has produced the first high-powered, randomly polarised laser beam with a "Q switch" laser, which typically emits pulses of light so brief that they're measured in nanoseconds. Lasers are a critical part of modern technology--they're used in everything from our ...
