1.   The microvalves use air to inflate a polymer coating into Braille dots.

2.   A new polymer coating holds the promise of guarding against infections commonly spread by bacteria lurking on things like telephones and door knobs, researchers say.

3.   A polymer seed coating can help prevent early germination, though results in some cases have been mixed during recent abnormal winters.

4.   Some of the methods include low-protein latex, adequate post-leaching, chlorination and polymer coating.

5.   The polymer coating deceives the platelets that trigger the re-narrowing process, said William Wagner, a bioengineer at Pitt.
