182Hf-182W age dating of a 26Al-poor inclusion and implications for the origin of short-lived radioisotopes in the early Solar System.
Proc. Natl. Acad. Sci. U. S. A. 110(22) , 8819-23, (2013) Refractory inclusions [calcium-aluminum-rich inclusions, (CAIs)] represent the oldest Solar System solids and provide information regarding the formation of the Sun and its protoplanetary disk. CAIs contain evidence of now extinct short-lived radioisotopes (e... |

Dispersion engineering of thick high-Q silicon nitride ring-resonators via atomic layer deposition.
Opt. Express 20(25) , 27661-9, (2012) We demonstrate dispersion engineering of integrated silicon nitride based ring resonators through conformal coating with hafnium dioxide deposited on top of the structures via atomic layer deposition. Both, magnitude and bandwidth of anomalous dispersion can ... |

Concentration dependence in kinetic arrest of the first-order magnetic transition in Ta doped HfFe2.
J. Phys. Condens. Matter 25(6) , 066011, (2013) Magnetic behavior of the pseudo-binary alloy Hf(1-x)Ta(x)Fe(2) has been studied, for which the zero-field ferromagnetic (FM) to antiferromagnetic (AFM) transition temperature is tuned near to T = 0 K. Our studies show that such composition lies around x = 0.2... |

Infrared spectroscopic and theoretical studies of the OTiF2, OZrF2 and OHfF2 molecules with terminal oxo ligands.
Dalton Trans. 41(38) , 11706-15, (2012) The isolated group 4 metal oxydifluoride molecules OMF(2) (M = Ti, Zr, Hf) with terminal oxo groups are produced specifically on the spontaneous reactions of metal atoms with OF(2) through annealing in solid argon. The product structures and vibrational spect... |

Ni ion release, osteoblast-material interactions, and hemocompatibility of hafnium-implanted NiTi alloy.
J. Biomed. Mater. Res. B. Appl. Biomater. 100(3) , 646-59, (2012) Hafnium ion implantation was applied to NiTi alloy to suppress Ni ion release and enhance osteoblast-material interactions and hemocompatibility. The auger electron spectroscopy, x-ray photoelectron spectroscopy, and atomic force microscope results showed tha... |

Immobilization mechanisms of deoxyribonucleic acid (DNA) to hafnium dioxide (HfO2) surfaces for biosensing applications.
ACS Appl. Mater. Interfaces 4(10) , 5360-8, (2012) Immobilization of biomolecular probes to the sensing substrate is a critical step for biosensor fabrication. In this work we investigated the phosphate-dependent, oriented immobilization of DNA to hafnium dioxide surfaces for biosensing applications. Phosphat... |

Hydrothermal chemistry, structures, and luminescence studies of alkali hafnium fluorides.
Inorg. Chem. 52(1) , 237-44, (2013) This paper describes the hydrothermal chemistry of alkali hafnium fluorides, including the synthesis and structural characterization of five new alkali hafnium fluorides. Two ternary alkali hafnium fluorides are described: Li(2)HfF(6) in space group P31m with... |

Transparent nanoscale floating gate memory using self-assembled bismuth nanocrystals in Bi(2) Mg(2/3) Nb(4/3) O(7) (BMN) pyrochlore thin films grown at room temperature.
Adv. Mater. 24(25) , 3396-400, (2012) Bismuth nanocrystals for a nanoscale floating gate memory device are self-assembled in Bi(2) Mg(2/3) Nb(4/3) O(7) (BMN) dielectric films grown at room temperature by radio-frequency sputtering. The TEM cross-sectional image shows the "real" structure grown on... |

Intensifying weathering and land use in Iron Age Central Africa.
Science 335(6073) , 1219-22, (2012) About 3000 years ago, a major vegetation change occurred in Central Africa, when rainforest trees were abruptly replaced by savannas. Up to this point, the consensus of the scientific community has been that the forest disturbance was caused by climate change... |

Laser conditioning on HfO2 film monitored by calorimeter.
Opt. Express 20(1) , 698-705, (2012) Conditioning effect on HfO2 single-layer film by quasi-cw laser was investigated. The conditioning process was monitored with laser calorimeter. Experimental results revealed that the HfO2 film absorption decreased as a function of the irradiation dose. Highe... |
