- Chemists make tiny molecular rings with big potential
11-02-2006 · EurekAlert!
Ohio State University chemists have devised a new way to create tiny molecular rings that could one day function as drug delivery devices or antibiotics. The rings are made from polymers -- large molecules that are made up of many smaller molecules -- and the chemical reaction that creates them is similar to others that create polymer chains. But this new reaction solely makes rings, ones tailored to perform specific functions.

- Rutgers scientists preserve and protect foods naturally
08-20-2007 · EurekAlert!
Chemists and food scientists at Rutgers joined forces to develop natural approaches to the prevention of food contamination and spoilage. They employed natural antimicrobial agents derived from sources such as cloves, oregano, thyme and paprika to create novel biodegradable polymers or plastics to potentially block the formation of bacterial biofilms on food surfaces and packaging. Biofilms may harbor multiple versions of infectious, disease-causing bacteria, such as Salmonella and E. coli.

- UD scientists discover new class of polymers
01-02-2007 · EurekAlert!
For years, polymer chemistry textbooks have stated that a whole class of little molecules called 1,2-disubstituted ethylenes could not be transformed into polymers -- the stuff of which plastics and other materials are made.However, UD scientists Chris Snively and Jochen Lauterbach were determined to prove the textbooks wrong. As a result of their persistence, the researchers have discovered a new class of ultra-thin polymer films with potential applications ranging from coating tiny microelectronic devices to plastic solar cells.
