Mixed valency in rare-earth fullerides.
Mixed-valence phenomena associated with the highly correlated narrow-band behaviour of the 4f electrons in rare earths are well documented for a variety of rare-earth chalcogenides, borides and intermetallics (Kondo insulators and heavy fermions). The family of rare-earth fullerides with stoichiometry RE2.75C60 (RE=Sm, Yb, Eu) also displays an analogous phenomenology and a remarkable sensitivit...
متن کاملLeaching and Kinetic Modelling of Molybdenite Concentrate Using Hydrogen Peroxide in Sulfuric Acid Solution
Leaching of molybdenite concentrate with hydrogen peroxide in sulfuric acid solution was investigated to determine the effects of reaction time, reaction temperature, H2O2 concentration, H2SO4 concentration, pulp density and rotation speed on molybdenum extraction and molybdenite dissolution kinetics, using the Taguchi method. From analysis of var...
متن کاملKINETIC STUDIES FOR GOLD LEACHING OF A REFRACTORY SULFIDE CONCENTRATE BY CHLORIDE–HYPOCHLORITE SOLUTION
In this paper, gold leaching of a refractory sulfide concentrate by chloride–hypochlorite solution was investigated and effects of stirring speed, temperature and particle size on the leaching rate were reported. Experimental data for leaching rate of gold were analyzed with the shrinking–core model. Results were consistent with chemical reaction control mechanism in the first 1 h of leachin...
متن کاملAmido-stabilized rare-earth metal mixed methyl methylidene complexes.
Donor(thf)-induced tetramethylaluminate cleavage of Ln(AlMe(4))(2)(NSiMe(3)Ar(iPr)) as well as the reaction of (LnMe(3))(n) (Ln = Y, Ho, Lu) with HNSiMe(3)Ar(iPr) in tetrahydrofuran affords unprecedented trinuclear rare-earth metal tetramethyl methylidene complexes which act as Schrock-type nucleophilic carbenes and methyl transfer agents.
متن کاملSome physical properties of rare-earth chlorides in aqueous solution
The aqueous solution behavior of some rare-earth chlorides has been investigated at 25° C. in the concentration range between 0.02 molal and saturation. Density measurements on solutions of lanthanum, neodymium, samarium, gadolinium, dysprosium, erbium, and ytterbium chlorides were carried out by a pycnometric method with an estimated accuracy of 1 x 10-5 gm.per ml. From the density data the ap...
