Dual-functioning displays, which can simultaneously transmit and receive information and energy through visible light, would enable enhanced user interfaces and device-to-device interactivity. We demonstrate that double heterojunctions designed into colloidal semiconductor nanorods allow both efficient photocurrent generation through a photovoltaic response and electroluminescence within a single device. These dual-functioning, all-solution-processed double-heterojunction nanorod light-responsive light-emitting diodes open feasible routes to a variety of advanced applications, from touchless interactive screens to energy harvesting and scavenging displays and massively parallel display-to-display data communication.

The incidence of orbital hemorrhage associated with cosmetic eyelid surgery is 0.055% (1:2,000), and orbital hemorrhage with permanent visual loss is 0.0045% (1:22,000) [corrected] Development of orbital hemorrhage is most common within the first 24 hours after surgery, especially within the first 0 to 3 hours, but can occur as late as several days after surgery.
