Reaction of (CpiPr4)2UI with NaN3 resulted in formation of tetrameric uranium(iii) azide-bridged 'molecular square' [(CpiPr4)2U(μ-η1:η1-N3)]4 (1). Addition of B(C6F5)3 to 1 induced loss of N2 at room temperature, yielding the uranium(v) borane-capped nitrido (CpiPr4)2U(μ-N)B(C6F5)3 (2).

Despite their importance as mechanistic models for heterogeneous Haber Bosch ammonia synthesis from dinitrogen and dihydrogen, homogeneous molecular terminal metal-nitrides are notoriously unreactive ...
Uranium compounds are used as fissile materials in nuclear reactors. In present day reactors the most used nuclear fuel is uranium dioxide, but in generation-IV reactors other compounds are also being...
Synthetic studies of bimetallic uranium nitride complexes with the N(SiMe3)2 ligand have generated a new nitride complex of U(III), which is highly reactive toward C-H bonds and H2. Treatment of the p...
A considerable amount of uranium (U(VI))-containing industrial wastewater is generated from both uranium mining and processing, and nuclear electrical power generation. Discharge of U(VI) containing w...
Reduction of the uranium(III) metallocene [(η 5 -C 5 i Pr 5 ) 2 UI] ( 1 ) with potassium graphite produces the 'second-generation' uranocene [(η 5 -C 5 i Pr 5 ) 2 U] ( 2 ), which contains uranium in...
The purpose of this study is to evaluate the response of human dental pulp to capping with MTA and NEC by histology and immunohistochemistry, using fibronectin and tenascin as markers, fol...

Management of deep carious lesions in permanent mature molars with reversible pulpitis represents a challenge for clinicians. Vital pulp therapy includes indirect and direct pulp capping, ...
Inorganic compounds that contain uranium as an integral part of the molecule.
Uranium. A radioactive element of the actinide series of metals. It has an atomic symbol U, atomic number 92, and atomic weight 238.03. U-235 is used as the fissionable fuel in nuclear weapons and as fuel in nuclear power reactors.
Radium. A radioactive element of the alkaline earth series of metals. It has the atomic symbol Ra, atomic number 88, and atomic weight 226. Radium is the product of the disintegration of uranium and is present in pitchblende and all ores containing uranium. It is used clinically as a source of beta and gamma-rays in radiotherapy, particularly BRACHYTHERAPY.
Nuclear reaction in which the nucleus of a heavy atom such as uranium or plutonium is split into two approximately equal parts by a neutron, charged particle, or photon.
Any chemical species which acts as an electron-pair donor in a chemical bonding reaction with a LEWIS ACID.
