Graphene Makes Novel OLEDs Display
Researchers at Stanford University have successfully developed a brand new concept of organic light-emitting diodes (OLEDs), using a few nanometers of graphene as a transparent conductor.
Metamaterials provide lenses with a broader vision
Researchers from Duke University, North Carolina have created a lens which has a field of view close to 180° and a zero f-number [Kundtz et al., Nat. Mater. (2009) doi: 10.1038/NMAT2610].
Using a silicon nanostructure cloak to render objects invisible
Researchers have made a breakthrough in the search for a cloaking device that can make objects appear invisible to the external observer, an area of enquiry that is attracting a lot of scientific interest.
