Closing the Loop on Recycling: Can We Stop the oil-to-Landfill Treadmill?
James L. Hedrick, Robert W. Waymouth
Poly(ethylene terephthalate) (PET), a widely used engineering thermoplastic for carpet, clothing (fibers), tire cords, soda bottles and other containers, film, automotive, electronics, displays etc., will contribute several billion pounds of waste to landfills this year alone! According to the American Plastics Council, PET packaging was originally used for soft drinks, but packing applications today include other beverages such as water, juice, beer, in addition to other foods such as peanut butter and ketchup and a variety of other household products.

Polymer Surface Viscoelasticity Affects Organic Thin-Film Transistor Performance
Thin polymer films exhibit glass transition temperatures (Tgs) that are depressed from the bulk material Tg because of increased degrees of chain motion. Using such films as gate dielectrics in organic thin-film transistors provides a sensitive new probe of polymer surface motional characteristics at the buried semiconductor-dielectric interface.

Brownian Motion of an Ellipsoid
Han, Y., Alsayed, A.M., Nobili, M., Zhang, J., Lubensky, T.C., and Yodh, A.G.
Brownian motion, the tiny random movements of small objects suspended in a fluid, has served as a paradigm for concepts of randomness ranging from noise in light detectors to fluctuations in the stock market.

A new way to keep bacteria at bay
Penicillin, long used in medications, is now being studied as a coating, a novel weapon against bacteria that could protect medical implants and the surgical tools used to insert them. The development could potentially save thousands of lives, as many patients contract infections following surgery.
