Abstract: Sheet-like graphene tends to stack with each other in thin films, resulting in relatively smooth microstructures with increased reflection as the thickness increases. In contrast, when the sheets are crumpled into a shape like paper… read more here.

DOI: 10.1364/ol.42.005234
Abstract: Based on chirped pulses, a wideband radio frequency (RF) channelized receiver that can easily support hundreds of channels is proposed. The mixing chirped pulses and its own delayed copy produces an equivalent RF local oscillation… read more here.
