Berkeley Lab nuclear physicists and materials scientists contribute to a remarkable advance in NMRNuclear magnetic resonance (NMR), a scientific technique associated with outsized, very low-temperature, superconducting magnets, is one of the principal tools in the chemist's arsenal, used to study everything from alcohols to proteins to such frontiers as quantum computing. In hospitals the machinery of NMR's cousin, magnetic resonance imaging (MRI), is as loud as it is big, but nevertheless a...

COLUMBUS, Ohio, Dec. 29 /PRNewswire/ -- CAS, a division of the American Chemical Society, announced today that scientists worldwide can now access more than 23.8 million predicted proton Nuclear Magnetic Resonance (NMR) spectra in SciFinder. SciFinder is the leading research and discovery tool and the authoritative source of information on more than 41 million chemical substances. These proton NMR spectra augment the 1.9 billion predicted and experimental properties and data tags already...

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...
