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...

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...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
