Darryl Smith knows how to make organic light-emitting diodes (OLED) more energy efficient than those available today. Current OLEDs have a transparent layer of electrically conductive material deposited on a substrate. Another layer of organic polymer, the one from which light is emitted, is deposited on the transparent layer. The third and final conducting layer is then deposited. Smith, a Los Alamos National Laboratory researcher, proved a method by which an intermediate chemical layer is applied between a conducting layer and the polymer layer of OLEDs, increasing the efficiency of current flow. He describes the single-molecule layer as a self-assembled polymer. The self-assembling layer has rows that line up in the same direction. Adding atoms at each end of the mono-molecule layer, the molecules "anchor" themselves to the conducting layer while maintaining polarity. The molecules' charged ends resemble the poles of a bar magnet. The thin layer shuttles electric charges between OLED's conducting and polymer layers. For more information, go to www.lanl.gov.
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
