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.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
