Review: Graphene could revolutionize photonic and opto-electronic devices

Optical Properties of Graphene, a book solely devoted to the optical properties of graphene, reviews the unique properties of graphene that hold great promise to revolutionize many photonic and opto-electronic devices.

Miniscule amounts of impurities in vacuum greatly affecting OLED lifetime

Reproducibility is a necessity for science but has often eluded researchers studying the lifetime of organic light-emitting diodes (OLEDs). Recent research sheds new light on why: impurities present in the vacuum chamber during fabrication but in amounts so small that they are easily overlooked.
