Reactivity of the dinuclear fulvalene cyclopentadienyl zirconium cationic species [{Zr(
The dinuclear cationic zirconium compound [{Zr( -C5H5)}2( -CH2)( -Cl)( -C5H4-C5H4)][BMe(C6F5)3] 1 reacts in dichloromethane at −78 °C with three equivalents of RNC (R= Bu, 2,6-Me2C6H3) via insertion into the Zr-methylene bond to give the new zirconium cationic species [{Zr( -C5H5)}2(Cl)(CNBu){ -[ -CN(Bu)-CH2-CN(Bu)}( -C5H4-C5H4)][BMe(C6F5)3] 2 and [{Zr( -C5H5)}2(Cl){CN(2,6-Me2C6H3)}[ -{CN(2,6-M...
متن کاملSynthesis of zirconia sol stabilized by trivalent cations (yttrium and neodymium or americium): a precursor for Am-bearing cubic stabilized zirconia.
Recent concepts for nuclear fuel and targets for transmuting long-lived radionuclides (minor actinides) and for the development of innovative Gen-IV nuclear fuel cycles imply fabricating host phases for actinide or mixed actinide compounds. Cubic stabilized zirconia (Zr, Y, Am)O(2-x) is one of the mixed phases tested in transmutation experiments. Wet chemical routes as an alternative to the pow...
متن کاملSynthesis and characterisation of zirconium complexes for cell tracking with Zr-89 by positron emission tomography.
The increasing availability of the long half-life positron emitter Zr-89 (half life 78.4 h) suggests that it is a strong candidate for cell labelling and hence cell tracking using positron emission tomography. The aim was to produce a range of neutral ZrL4 lipophilic complexes for cell labelling which could be prepared under radiopharmaceutical conditions. This was achieved when the ligand was ...
متن کاملNew Zr II oscillator strengths and the zirconium conflict in the HgMn star χ Lupi
Lifetimes on the sub-nanosecond scale for the levels vD3/2, vF3/2 and vF5/2 in the 4d5s5p configuration in Zr II have been measured, using the method of laser-induced fluorescence. Combined with branching fractions obtained with the Lund Ultraviolet (UV) Fourier Transform Spectrometer (FTS), experimental oscillator strengths have been derived. From Hubble Space Telescope/Goddard High-Resolution...
متن کاملFunctionalizing porous zirconium terephthalate UiO-66(Zr) for natural gas upgrading: a computational exploration.
The ligand functionalization effect on the CO(2)/CH(4) separation performance of the MOF type UiO-66(Zr) was explored computationally. The -SO(3)H and -CO(2)H functionalized forms show the highest selectivity, good working capacity and medium ranged CO(2) adsorption enthalpy that make these materials very promising for physisorption-based processes.
