Scientists at nasa 's jet propulsion laboratory in pasadena are aiming to develop an arm powered by bionic muscles made from these " electroactive polymers " that would be capable of winning an arm-wrestling contest .
Biobutanol can be used as a substitute for petroleum-based n-butanol , a chemical used in the production of polymers and plastics , and as a solvent in paint .
Peter shepard , novomer 's executive vice president of polymers explained , explained the company 's process to me .

Polymers can be used to coat a drug to prevent it being released in the stomach , or to produce a slow release of drug .
这种聚合物常用来涂于药物表面以保护药物不在胃中溶解或者使药物缓慢释放。
Lcd is liquid crystal diode , whereas the organic light emitting diode ( oled ) is made of a thin film of organic polymers .
lcd是液态晶体二极管的英文缩写,然而,有机发光二极管(即oled)是由有机聚合物薄膜制成。
Dr. david keith proposed that the abyssal plain be the site for huge bags made of polymers , about 600 feet ( 183 meters ) in diameter to serve as storage containers for liquid carbon dioxide .
In the second stage , lactic-acid molecules are linked into long chains , or polymers , in chemical-reaction vessels , to produce pla .
其次,乳酸分子于化学反应容器中连成长链或组成聚合物,然后产生聚乳酸纤维。
Among discoveries in the lab over recent years is that when a vesicle 's cargo of nucleic acid polymers fills up to the point it strains the cell 's wall , the membrane will greedily absorb any fatty acids floating by .
However , these channels are much shorter than the new nanotube channels ( the nanotubes are about 20000 times longer ) , so they only permit passage of large molecules such as dna or polymers - anything smaller would move too quickly to be detected .
