Ionic liquids as solvents for rare-earth metals: a combined XAS and Molecular Dynamics study
Full text linkIn this work a detailed investigation of the structural organization of ILs, both monocationic and dicationic, and their water mixtures has been carried out by combining XAS spectroscopy and Classical MD simulations. The same joint XAS-MD approach has been also applied to the study of the solvation properties of Ln(III) salts dissolved in ILs. The original application of EXAFS and MD simulations paves the route for the systematic use of an integrated approach, with increased reliability, in the structural investigation of ILs. All together these issues are expected to be of great help in the systematic design of IL systems to meet the requirements of key applications

Electrodeposition of stoichiometric polycrystalline ZnTe on n+-GaAs and Ni-P
No full textAn acid aqueous sulphate electrolyte is proposed for the low temperature direct electrochemical growth of single-phase polycrystalline ZnTe. Single-crystal n+-GaAs and amorphous electroless Ni-P were used as substrates. The relationship between electrochemical growth conditions and the crystalline structure of as-deposited ZnTe were disclosed and correlated to the cathode chemistry during the growth process. Under suitable plating conditions the removal of tellurium (Te) excess from the deposit can be achieved, resulting in stoichiometric ZnTe. The nucleation of ZnTe was assessed through morphology observations by scanning electron microscopy: an instantaneous type prevails on GaAs and a progressive one on amorphous Ni-P. Chemical depth profiles of Zn and Te were investigated by X-ray photoelectron spectrometry measurements
