Researchers from the MOE Key Laboratory of Macromolecular Synthesis and Functionalization, Department of Polymer Science and Engineering, Zhejiang University, China, have expanded the range of monomer pairs used in their established metal-free click polymerization of aroylacetylene"“azides to propiolate"“azides. They efficiently prepared functional poly(aroxycarbonyltriazole) compounds with aggregation-induced emission characteristics. This study was reported in Volume 54 (Number...

Using a small block of aluminum with a tiny groove carved in it, a team of researchers from the National Institute of Standards and Technology (NIST) and the Polytechnic Institute of New York University is developing an improved "green chemistry" method for making biodegradable polymers. Their recently published work* is a prime example of the value of microfluidics, a technology more commonly associated with inkjet printers and medical diagnostics, to process modeling and development for...

New method allows for more precise control over ATRP, a popular technique used for creating specialized plastics Scientists led by Carnegie Mellon University chemist Krzysztof Matyjaszewski are using electricity from a battery to drive atom transfer radical polymerization (ATRP), a widely used method of creating industrial plastics. The environmentally friendly approach, reported in the April 1 issue of Science, represents a breakthrough in the level of control scientists can achieve over the...

ST. LOUIS, March 11 /PRNewswire-FirstCall/ -- Sigma-Aldrich (Nasdaq: SIAL) announced today that it has entered into a worldwide licensing agreement with Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO) to manufacture and sell Reversible Addition-Fragmentation chain Transfer (RAFT) agents - organic molecules that can be added to polymerization reactions to precisely control molecular weights and structures of polymers. Under the terms of the agreement,...

By Lawrie, Kirsten J Meredith, Paul; McGeary, Ross P ABSTRACT The isolation, structure determination and chemical characterization of eumelanins has been plagued by their very low solubility in organic solvents. To gain insights into the structure and reactivity of these unusual and important biologic macromolecules and to pave the way for their use in electronics, we have prepared soluble melanins via the synthesis of monomeric precursors containing lipophilic substituents. Two such...

By Rao, T Prasada Prasad, K; Kala, R; Gladis, J Mary Toxic pesticides and heavy metals constitute an important class of pollutants that degrade the environment due to their persistent nature and their unavoidable use in increasing the agricultural output and industrial importance respectively. The design and development of portable devices such as sensors rather than laboratory based instruments in monitoring the above species at trace levels in real samples is prime challenge to analytical...

By Gupta, Neal S; Briggs, Derek E G; Pancost, Richard D Graptolites are important fossils in Early Palaeozoic assemblages. Preserved graptolite periderm consists dominantly of an aliphatic polymer, immune to base hydrolysis. It contains no protein even though its structure, and chemical analyses of the periderm of the living relative Rhabdopleura, indicate that it was originally collagen. This anomaly was previously interpreted as the result of replacement by macromolecular material from...

BERKELEY, CA "“ Microtubules are active protein polymers critical to the structure and function of cells and the process of cell division. In a living cell their growing ends constantly elongate and retreat in a thrashing frenzy of polymerization and depolymerization, like the writhing snakes of Medusa's hair. Known prosaically as "dynamic instability," this ongoing rapid growth and shrinkage is key to the diverse workings of microtubules in the cell.  For the first time,...
