Graphene 'smart surfaces' now tunable for visible spectrum

Researchers at The University of Manchester's National Graphene Institute have created optical devices with a unique range of tunability, covering the entire electromagnetic spectrum, including visible light.

Graphene layer enables advance in super-resolution microscopy

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows ...

Dense yet transparent materials offer new way to control light

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to novel ...

Silicon-based metamaterials could bring photonic circuits

New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance.

Scientists discovering new uses for tiny carbon nanotubes

Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how to incorporate ...

Researchers develop photostimulated transparent glass ceramic

Magnetic data storage has been gradually replaced by optical data storage (ODS) with higher efficiency, lower energy consumption, larger capacity, and longer service lifetime. As a classical kind of ODS medium, photostimulated ...

Nanopaper as an optical sensing platform

An international team led by the ICREA Prof Arben Merkoçi has just developed new sensing platforms based on bacterial cellulose nanopaper. These novel platforms are simple, low cost and easy to produce and present outstanding ...
