Geräte- und transducerunabhängige 3D-Sonographie im Mund-Kiefer-Gesichtsbereich*

Autor: Nuber B, R. Sader, H. Deppe, Hans-Florian Zeilhofer, H H Horch, B Hornung

Publikováno v: Ultraschall in der Medizin. 16:269-274

Aim The use of a new 3D ultrasound system should reduce the drawbacks of former 3D workstations (long image generation time, limited use due to the need for special 3D transducers), so that it is now applicable in daily clinical routine. Method An ul

Die dreidimensionale Ultraschalldiagnostik in Gynäkologie und Geburtshilfe

Autor: Hornung B, W. Stolz, Hesse A, Nuber B, Ch. Sohn

Publikováno v: Geburtshilfe und Frauenheilkunde. 51:335-340

Three-dimensional reconstruction of an organ requires a coordinated sequence of cross-sectional scans. In ultrasound this can be solved by rotating the scan plane horizontally or vertically. Two scan heads have been built, one to rotate the plane aro

Von Cp+2Nb(η2-S2)H zu CP+3Nb3S12: Reaktivitätsstudien an Niobocensulfiden ( = FROM CP+2NB(ETA-2-S2)H TO CP+3NB3S12 - REACTIVITY STUDIES ON NIOBOCENE SULFIDES)

Autor: Brunner, H., Gehart, G., Meier, W., Wachter, Joachim, Nuber, B.

The reaction of Cp+2bBH4 with sulfur gives two isomers of composition Cp+2NbS2H (3, 4) and Cp+2NbS3H (5). The structures of 3-5 have been investigated by IR and H-1 NMR spectroscopic means. X-Ray diffraction analyses have been performed on 3 and 4. T

Publikováno v: Journal of Organometallic Chemistry, 435(3), 275-289. Elsevier Science

The dielectricity constant and the dipole moment of the 1:1 adducts of the tris(cyclopentadienyl)compounds of the trivalent lanthanoids La to Lu (with exception of the Pm compound) and of the lighter actinoids Th, U, Np, and Pu with tetrahydrofuran,

Präparative, 11B-, 93Nb-NMR-spektroskopische und strukturelle Untersuchungen an Cp2NbBH4- und [CpNb(B2H6)]2-Komplexen (= PREPARATORY ANALYSIS, B-11 NMR-SPECTROSCOPY, NB-93 NMR-SPECTROSCOPY AND STRUCTURAL-ANALYSIS OF CP2NBBH4 COMPLEXES AND [CPNB(B2H6)] COMPLEXES)

Autor: Brunner, Henri, Gehart, G., Meier, W., Wachter, Joachim, Wrackmeyer, B., Nuber, B., Ziegler, M. L.

NbCl5 reacts with NaBH4 and LiCp+ (Cp+ = EtMe4C5) dependent on the stoichiometry and temperature to give Cp+2NbCl2 (1), CP+2Nb2Cl2(B2H6)(2), CP+2NbBH4(3a) and Cp+ 2Nb2(B2H6)2 (4a). With a large excess of NaBH4, Cp+ 2NbCl2 gives 2 at 25-degrees-C, whi

Synthese und strukturelle Charakterisierung von Bis(pentamethylcyclopentadienylmolybdän-μ-sulfido)-Komplexen mit μ,η1-SSR-Liganden(= SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF BIS(PENTAMETHYLCYCLOPENTADIENYLMOLYBDENUM-MU-SULFIDO) COMPLEXES WITH MU,ETA-1-SSR LIGANDS)

Autor: Brunner, Henri, Grassl, R., Wachter, Joachim, Nuber, B., Ziegler, M. L.

The reaction of Cp2*Mo2S4I2(Cp* = eta(5)-C5Me5) with two equivalents of NaSR (R = Me, (i)Pr, (t)Bu, Ph) gives the complexes Cp2*Mo2(mu,eta(1)-SSR)2(mu-S)2 (2a-d) in nearly quantitative yields. The compounds have been investigated spectroscopically an
