A new blue
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with a possible new source of blue pigmentation. More particularly it focuses on pigmentation that seems more durable and less harmful than its predecessors. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of matter processing.
The manufacture of blue pigmentation has held great challenges to producers. In the past blue pigments have often been "expensive", "poisonous" or "apt to fade". Blue pigmentation was derived from different basic materials. These included lapis lazuli, a gemstone; cobalt blue, possibly toxic; Prussian blue, a possible source of cyanide; or organic materials that could not withstand heat and acidity. (Chang, Kenneth, "By Happy Accident, Chemists Produce a New Blue", New York Times, November 24, 2009, D6)
At Oregon State University, researchers have now come across a possible source of blue pigmentation that promises to be far more affordable, non-toxic and permanent.
The interesting feature of this development is
  • Serendipity
  • Creative association
Dr. Mas Subramanian headed a research team that heated materials to seek novel electronic properties. They looked at manganese oxide (a black substance), combined with yttrium oxide (white), and indium oxide (yellow). The material exhibited an intense blue color that remained stable when cooled. Although coloring was unrelated to the primary research goal, Dr. Subramanian recognized the potential for innovation in pigmentation.
According to the NASA definition of nine technology readiness levels (TRLs), this technology is now at TRL 3. At present the cost is still too high to ensure commercial success. We expect focused initiatives to drive this cost down.
