A new way to make sheets of graphene

Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations to wider ...

Sweet solutions for detecting disease

Based at the Institute of Chemistry in the Slovak Academy of Sciences, Ján Tkáč's research combines glycomics – the study of sugars in organisms – with biochip sensors based on nanoparticles and nanotubes. The complexity ...

Unique nanostructure produces novel 'plasmonic halos'

Using the geometric and material properties of a unique nanostructure, Boston College researchers have uncovered a novel photonic effect where surface plasmons interact with light to form "plasmonic halos" of selectable output ...

New LED packaging technology improves performance

(Phys.org)—Many researchers have reported improvements in LED technology by enhancing the properties of the LED itself. But the packaging that secures and protects the LED also impacts its overall performance. In a new ...

'Dark plasmons' transmit energy

Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.
