  • Publication number: 20150064113
    Abstract: Methods are described for preparing magnetic resonance imaging (MRI) and/or magnetic resonance spectroscopy contrast agents where the contrast agents are prepared from precursor molecules having at least four non-zero-spin nuclei that form two pairs of chemically equivalent or effectively equivalent nuclei, e.g., diphenylacetylene or diethyl oxalate. The precursor molecule is hyperpolarized and a sequence of one or more radiofrequency pulses is applied to transfer spin state population between the first and second pair of nuclei, thereby providing a non-equilibrium single state nuclear spin population. To detect the contrast agent, another sequence of one or more radiofrequency pulses is applied to transfer singlet order to polarization. No transformation of the molecular structure of the contrast agent is necessary for detection. Also described are methods of imaging targets using the contrast agents.

In one form, the lube base stock includes from 10 to 35 wt. % paraffins, 40 to 70 wt. % 1-ring naphthenes, and 0 to 40 wt. % combined 2-ring naphthenes and aromatics, and has a ratio of 1-ring naphthenes to paraffins from 1.8 to 5.0, and a Viscosity Index of from 100 to 160. The lube base stock has a 14C level ranging from 2 to 101% of the modern day 14C level in the atmosphere, and yields a CCS ratio (Cold Crank Simulator (CCS) viscosity to the predicted CCS viscosity by Walther equation) of less than or equal to 0.85 at ?35° C. The base stocks are useful as in formulated lubricant compositions requiring improved low temperature properties.
