Ameise und Elefant: Neuartige mikrofluidische Glas‐Chips mit integriertem Nanospray‐Emitter wurden mit einem massenspektrometrischen Detektor gekoppelt. Eine elektrophoretische Variante des Systems ermöglicht die Trennung und Analyse z. B. von Pharmazeutika und bietet Perspektiven für die Detektion kleinster Probenmengen im Hochdurchsatzverfahren.
A series of nickel(II) b-ketoimine complexes, {Ni[CH 3 -C(O)CHC(CH 3 )NR] 2 , R CH 3 , C 4 H 9 }, and ketoiminates, {Ni[CH 3 C(O)CH(CH 3 )C(-N(CH 2 ) n N-)C(CH 3 )CHC(O)CH 3 ], n 2, 6, 8, 9}, and their adducts with 2,2 H -bipyridine (bipy) and 1,10-phenanthroline (phen) have been synthesized and characterized using elemental analyses, magnetic susceptibility, conductivity, infrared and electronic spectral measurements. The ketoimine ligands coordinate to the nickel atom in a bidentate fashion using the N 2 O 2 chromophore. A range of stereochemistries was observed for the nickel(II) ketoiminates from four-coordinate tetrahedral and square-planar geometry to six-coordinate octahedral geometry. Conductivity
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
