Solvation of 1-butyl-3-methylimidazolium hexafluorophosphate in aqueous ethanol--a green solution for dissolving 'hydrophobic' ionic liquids.

Chemical communications (Cambridge, England)

Swatloski RP, Visser AE, Reichert WM, Broker GA, Farina LM, Holbrey JD, Rogers RD.
PMID: 12240168
Chem Commun (Camb). 2001 Oct 21;(20):2070-1. doi: 10.1039/b106601n.

The relatively hydrophobic ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate has been found to be totally miscible with aqueous ethanol between 0.5 and 0.9 mol fraction ethanol, whereas the ionic liquid is only partially miscible with either pure water or absolute ethanol;...

Identification of spores in the polycentric anaerobic gut fungi which enhance their ability to survive.

FEMS microbiology ecology

Brookman JL, Ozkose E, Rogers S, Trinci AP, Theodorou MK.
PMID: 10719208
FEMS Microbiol Ecol. 2000 Mar 01;31(3):261-267. doi: 10.1111/j.1574-6941.2000.tb00692.x.

Two new isolates of the gut fungi were obtained from the rumen digesta and faeces of a cow. These isolates, designated Anaeromyces following rDNA typing, displayed a polycentric growth habit but differed from all other gut fungi in that...

1,3-dimethylimidazolium-2-carboxylate: the unexpected synthesis of an ionic liquid precursor and carbene-CO2 adduct.

Chemical communications (Cambridge, England)

Holbrey JD, Reichert WM, Tkatchenko I, Bouajila E, Walter O, Tommasi I, Rogers RD.
PMID: 12610949
Chem Commun (Camb). 2003 Jan 07;(1):28-9. doi: 10.1039/b211519k.

1,3-Dimethylimidazolium-2-carboxylate is formed in good yield, rather than the anticipated organic salt, 1,3-dimethylimidazolium methyl carbonate, as the reaction product resulting from both N-alkylation and C-carboxylation of 1-methylimidazole with dimethyl carbonate; the crystal structure of the zwitterion exhibits pi-stacked rings...

Associations of Vertebrate Skeletal Concentrations and Discontinuity Surfaces in Terrestrial and Shallow Marine Records: A Test in the Cretaceous of Montana.

The Journal of geology

Rogers RR, Kidwell SM.
PMID: 10736266
J Geol. 2000 Mar;108(2):131-154. doi: 10.1086/314399.

Although lags of bones and teeth are commonly cited criteria for marine unconformities, the consistency of the association of vertebrate fossils and discontinuity surfaces, as well as the taphonomic (postmortem) controls on this relationship, are poorly understood. A field...

Aqueous biphasic systems. Partitioning of organic molecules: a QSPR treatment.

Journal of chemical information and computer sciences

Katritzky AR, Tämm K, Kuanar M, Fara DC, Oliferenko A, Oliferenko P, Huddleston JG, Rogers RD.
PMID: 14741019
J Chem Inf Comput Sci. 2004 Jan-Feb;44(1):136-42. doi: 10.1021/ci034194o.

The partitioning of 29 small organic probes in a PEG-2000/(NH4)2SO4 biphasic system was investigated using a quantitative structure-property relationship (QSPR) approach. A three-descriptor equation with the squared correlation coefficient (R2) of 0.97 for the partition coefficient (log D) was...

Clinical utility of PET-FDG imaging in differentiation of benign from malignant adrenal masses in lung cancer.

Clinical lung cancer

Gupta NC, Graeber GM, Tamim WJ, Rogers JS, Irisari L, Bishop HA.
PMID: 14656394
Clin Lung Cancer. 2001 Aug;3(1):59-64. doi: 10.3816/clc.2001.n.019.

This study was designed to evaluate the sensitivity, specificity, and predictive accuracy of PET-FDG imaging in detecting metastatic disease involvement of adrenal glands in patients with lung cancer. We wanted to compare efficacy of positron emission tomography (PET)-fluorodeoxyglucose (FDG)...

Identical extraction behavior and coordination of trivalent or hexavalent f-element cations using ionic liquid and molecular solvents.

Dalton transactions (Cambridge, England : 2003)

Cocalia VA, Jensen MP, Holbrey JD, Spear SK, Stepinski DC, Rogers RD.
PMID: 15909044
Dalton Trans. 2005 Jun 07;(11):1966-71. doi: 10.1039/b502016f. Epub 2005 May 03.

The extraction of both UO2(2+) and trivalent lanthanide and actinide ions (Am3+, Nd3+, Eu3+) by dialkylphosphoric or dialkylphosphinic acids from aqueous solutions into the ionic liquid, 1-decyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide has been studied and compared to extractions into dodecane. Radiotracer partitioning...
