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.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
