"One thing we want to do is figure out how to expand the polymers even more," says Boyden.
"Another priority for us is to build stronger polymers, or find a way of reinforcing them in the expanded state, and we're now screening lots of chemicals to find ones that retain their strength after expansion".
The Koch brothers, whose wide-ranging corporation extends into oil refineries, fertilizer production and polymers, paper and minerals, avidly inject cash into both political causes and cultural ones and do not always shy from the spotlight.
Professor Richard Thompson, the marine scientist from Plymouth University who coined the term "microplastics" and has traced how plastics degrade in the ocean, has consistently pointed out that nine different polymers consistent with water bottle production are routinely found in marine samples.
Still not tallying Pretty polymers Relegation ahead The golden spigot Taxing the poor to pay the poor ReprintsIn another concession, Sir David Tweedie, the chairman of the IASB, promised to establish a working group to look at ways of simplifying and improving IAS 39.
In the late 1980s, a team at the University of Cambridge developed a whole new family of OLEDs that used polymers instead of small organic molecules as the display's emitter.
He has set ambitious targets: the chemicals division is to achieve a return on sales of at least 12%, polymers 15% and agrochemicals 20%, by 2005 at the latest.Bayer is already doing deals to boost its chances.
Though Hoechst, once the local chemical giant, was absorbed into sanofi-aventis of France in 1999, its Frankfurt site still churns out polymers, pigments and pharmaceuticals.
The printing materials, mostly polymers such as acrylonitrile butadiene styrene or polylactic acid, lack the mechanical strength needed for making parts sturdy enough to do a useful job.
The problem in the past was that, because the diodes were made from costly semiconductors such as gallium arsenide and gallium nitride, they were not only tricky but also expensive to bunch up into high-resolution displays.By contrast, OLED displays use new kinds of semiconducting compounds called "conjugated polymers".
One option is to use sequentially triggered vertebrae made of electroactive polymers, whose shape is modified by applying a voltage.All this makes the robotic tuna's new incarnation ever more reminiscent of the real thing.
