Crystal Structures of Al–Nd Codoped Zirconolite Derived from Glass Matrix and Powder Sintering

23.07.2015 | Chang-Zhong Liao; Kaimin Shih; William E. Lee, Inorganic Chemistry, 2015

Zirconolite is a candidate host for immobilizing long-lived radionuclides. Zirconolite-based glass-ceramics in the CaO-SiO2-Al2O3-TiO2-ZrO2-Nd2O3-Na2O matrix are a potential waste form for immobilizing actinide radionuclides and can offer double barriers to immobilize radioactive elements. ...

Singlet–Triplet Gaps of Cobalt Nitrosyls: Insights from Tropocoronand Complexes

23.07.2015 | Kathrin H. Hopmann; Jeanet Conradie; Espen Tangen; Zachary J. Tonzetich; Stephen J. Lippard; Abhik Ghosh, Inorganic Chemistry, 2015

A density functional theory (DFT) study of {CoNO}8 cobalt nitrosyl complexes containing the [n,n]tropocoronand ligand (TC-n,n) has revealed a sharp reduction of singlet–triplet gaps as the structures change from near-square-pyramidal (for n = 3) to trigonal-bipyramidal with an equatorial NO (for ...
