Praseodymium(III) sulfate hydroxide, Pr(SO4)(OH)
The title compound, Pr(SO(4))(OH), obtained under hydro-thermal conditions, consists of Pr(III) ions coordinated by nine O atoms from six sulfate groups and three hydroxide anions. The bridging mode of the O atoms results in the formation of a three-dimensional framework, stabilized by two O-H⋯O hydrogen-bonding inter-actions.
متن کاملAtomic Layer Deposition of Praseodymium Aluminum Oxide for Electrical Applications
Praseodymium aluminum oxide (PAO) thin films were grown by atomic layer deposition (ALD) from a new precursor, tris(N,N′-diisopropylacetamidinato) praseodymium, (Pr(amd)3), trimethylaluminum (TMA), and water. Smooth, amorphous films having varying compositions of the general formula PrxAl2–xO3 were deposited on HF-last silicon and analyzed for physical and electrical characteristics. The films ...
متن کاملPrecipitation evolution in Al–Zr and Al–Zr–Ti alloys during aging at 450–600 C
The transformation of Al3Zr (L12) and Al3(Zr1 xTix) (L12) precipitates to their respective equilibrium D023 structures is investigated in conventionally solidified Al–0.1Zr and Al–0.1Zr–0.1Ti (at.%) alloys aged isothermally at 500 C or aged isochronally in the range 300– 600 C. Titanium additions delay neither coarsening of the metastable L12 precipitates nor their transformation to the D023 st...
متن کاملReactivity 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 کاملCatalytic Oxidation of CO and Soot over Ce-Zr-Pr Mixed Oxides Synthesized in a Multi-Inlet Vortex Reactor: Effect of Structural Defects on the Catalytic Activity
In the present work, ceria, ceria-zirconia (Ce = 80 at.%, Zr = 20 at.%), ceria praseodymia (Ce = 80 at.%, Pr = 20 at.%) and ceria-zirconia-praseodymia catalysts (Ce = 80 at.%, Zr = 10 at.% and Pr = 10 at.%) have been prepared by the multi-inlet vortex reactor (MIVR). For each set of samples, two inlet flow rates have been used during the synthesis (namely, 2 ml min-1, and 20 ml min-1) in order ...
