Nd-Zn (Neodymium-Zinc)

Two nd-zn and sm-zn isonicotinic/nicotinic Acid complexes.

The 4f-3d heterometallic complexes [Nd(L)3(H2O)2]2(ZnCl4)3n • 4nH2O (1) (L = isonicotinic acid) and [Sm(L')3(H2O)2]2(ZnCl4)n • 2nH2O (2) (L' = nicotinic acid) have been obtained by hydrothermal reactions and structurally characterized by X-ray single-crystal diffractions. Both complexes feature an infinite 1-D polycationic chain-like structure. Photoluminescent investigations reveal that both c...

Experimental lifetime determination in neutral praseodymium (Pr I) and neodymium (Nd I)

Radiative lifetime measurements have been performed, with a time-resolved laser-induced fluorescence technique, for 18 even-parity levels of Pr I and 15 odd-parity levels of Nd I. The new results are compared with the few experimental data available in the literature and good agreement is found. However, fragmentary knowledge of the spectra prevents reliable calculation of branching fractions a...

Influence of neodymium concentration on excitation and emission properties of Nd doped gallium oxide nanocrystalline films

In vitro Evaluation of Dentin Surface Irradiated by Neodymium-doped: Yttrium Aluminum Garnet Laser (Nd: YAG) Using Scanning Electron Microscopy

Introdouction: Dentinal hypersensitivity (DH) is one of the most painful chronic problems reported in dental offices. Various methods have been applied for the treatment of DH. However, majority of them are either ineffective or last for a short period of time. It has been reported that lasers, particularly Neodymium- doped: Yttrium Aluminum Garnet laser (Nd: YAG), can be helpful in the treatme...

Organocatalytic photoreduction of Zn(II) to zinc metal.

The photoreduction of Zn(II) to Zn metal catalyzed by 8-hydroxyquinoline derivatives is reported. Structure-activity relationships, ideal reaction conditions, and the reaction kinetics are described and a mechanism involving an in situ formed quinolate complex is portrayed.
