Abstract: Methods for producing regioregular poly(aryl ethynyl)-poly(aryl vinyl) and monomers for preparing the regioregular poly(aryl ethynyl)-poly(aryl vinyl) polymers are described herein. Regioregular poly(aryl ethynyl)-poly(aryl vinyl) are useful for electronics, among other things.
Abstract: Techniques and systems for reclaiming metals from articles having one or more components containing or coated with copper are provided. An example technique may include providing an article having one or more components containing or coated with copper, providing a barrel disposed in a container, the container containing an electrolytic solution and a copper starting pole component, positioning a plurality of electrically conductive particles and the article within the barrel, and separating one or more copper ions from at least a portion of the article by electrolysis.
Abstract: Techniques are generally described for touch-sensitive devices with biometric information determination capabilities. The touch-sensitive device may include one or more of a transmitter, a receiver, and a processor. The transmitter may be configured to emit light towards a surface of the touch-sensitive device and the receiver may be configured to receive reflected light from a touch to the touch-sensitive device. The processor may be arranged to receive signals from the receiver and determines biometric information, and in some examples location of touch, based on the signals.
