Tuning of the size of Dy2O3 nanoparticles for optimal performance as an MRI contrast agent.
J. Am. Chem. Soc. 130(15) , 5335-40, (2008) The transverse 1H relaxivities of aqueous colloidal solutions of dextran coated Dy2O3 nanoparticles of different sizes were investigated at magnetic field strengths (B) between 7 and 17.6 T. The particle size with the maximum relaxivity (r2) appears to vary b... |

Development and testing of passive tracking markers for different field strengths and tracking speeds.
Phys. Med. Biol. 51(6) , N127-37, (2006) Susceptibility markers for passive tracking need to be small in order to maintain the shape and mechanical properties of the endovascular device. Nevertheless, they also must have a high magnetic moment to induce an adequate artefact at a variety of scan tech... |

Sonochemical synthesis of Dy2(CO3)3nanoparticles, Dy(OH)3nanotubes and their conversion to Dy2O3nanoparticles
Ultrason. Sonochem. 17(5) , 870-7, (2010) Dysprosium carbonates nanoparticles were synthesized by the reaction of dysprosium acetate and NaHCO 3 by a sonochemical method. Dysprosium oxide nanoparticles with average size about 17 nm were prepared from calcination of Dy 2(CO 3) 3·1.7H 2O nanoparticles.... |

Homogeneous precipitation of Dy2O3 nanoparticles-effects of synthesis parameters.
J. Nanosci. Nanotechnol. 7(3) , 907-15, (2007) The experimental parameters that control the size and size distribution of dysprosium oxide nanoparticles synthesized by homogeneous precipitation technique have been systematically investigated. The particles were characterized with respect to their size, sh... |

Temperature-dependent assemblies from a 2-D triple-stranded meso-helical layer to a 3-D chain-layer metal-organic framework.
Dalton Trans. 41(47) , 14239-43, (2012) Two different crystal forms, namely {[Dy2(mpda)3(H2O)2]·H2O}n (1) and [Dy2(mpda)3(H2O)4]n (2), were obtained from the reaction of multidentate 2,6-dimethylpyridine-3,5-dicarboxylic acid (H2mpda) with Dy2O3 at different temperatures. Structural analysis reveal... |

Emission analysis of Dy(3+):Ca(4)GdO(BO(3))(3) powder phosphor.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 71(3) , 951-3, (2008) Emission spectrum of Dy(3+):Ca(4)GdO(BO(3))(3) powder phosphor has been analyzed. Two emission bands at 492 and 588 nm with lambda(exci)=311 nm ((6)H(15/2)-->(4)L(19/2)) have been measured from this phosphor. For the intense yellow emission at 588 nm ((4)F(9/... |

Hepatic contrast agents for computed tomography: high atomic number particulate material.
J. Comput. Assist. Tomogr. 5(3) , 370-4, (1981) We used a stepwise approach to identify, design, synthesize, and test new high atomic number particulate contrast agents that would be especially well suited for use with computed tomography (CT). Our goal was to produce extremely radiopaque compounds with hi... |

[Correction for the spectral interferences of rare-earth matrix to the determination of calcium by spectral fitting matrix projection-Kalman filter method].
Guang Pu Xue Yu Guang Pu Fen Xi 21(1) , 73-6, (2001) The spectral interferences of trace elements from high purity rare earth will seriously affect the analytical accuracy in the ICP-AES analysis. In this work, spectral fitting matrix projection-Kalman filter method was developed and applied to correction of sp... |
