The title centrosymmetric dinuclear dysprosium(III) complex, [Dy(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)] or [Dy(L)(3)phen](2), is comprised of six 3,4-dimethoxy-phenylacetate (L) anions, two 1,10-phenanthroline (phen) mol-ecules and two Dy(III) ions. The Dy(III) atom is nine-coordinated by seven O atoms from five L ligands and two N atoms from the phen mol-ecules. The L ligands are coordinated...

We utilize the Shell Model Monte Carlo (SMMC) method to study the structure of rare earth nuclei. This work demonstrates the first systematic " full oscillator shell plus intruder " calculations in such heavy nuclei. Exact solutions of a pairing plus quadrupole hamiltonian are compared with mean field and SPA approximations in several Dysprosium isotopes from A = 152 − 162, including the odd ma...

The design preciseness, the material used in productivity plus the time are coming the most important factors in motor manufacturing. Consequently, the use of interior permanent magnet synchronous machines (IPM) in hybrid vehicle seemed to be the best demands. However, and due to the earth magnet materials increasing prices such as Dysprosium and Neodymium, automobile manufacturers have looked ...

A new method for magnetic separation of cells is described. Based on cellular concentration of complexed paramagnetic cations from a carrier solution, the method achieves highly repeatable separations, at lower magnetization fields, than existing HGMS cell-separation methods. Feasibility has been shown for erbium and dysprosium, with whole blood as the sample. Single-pass magnetic separation ef...

The observed rate of reaction in the dysprosium triflate catalyzed aza-Piancatelli rearrangement is controlled by a key off-cycle binding between aniline and catalyst. Deconvoluting the role of these ancillary species greatly broadens our understanding of factors affecting the productive catalytic pathway. We demonstrate that the rate of reaction is controlled by initial competitive binding bet...
