Reactive MALDI Mass Spectrometry of Saturated Hydrocarbons: A Theoretical Study

May 1, 2010
Author(s)
William E. Wallace, Lewandowski Hans, Meier J. Robert
Recently it has been shown that the cobaltocenium cation, prepared by the laser ablation of a CoCp(CO)2/fullerene matrix, may react with alkanes and polyethylenes in the gas phase via a dehydrogenation reaction to produce [Co(Cp)2(alkadiene)]+ ions without

X-Ray and Neutron Powder Diffraction Studies of (Ba 1-x Sr x )Y 2 CuO 5

May 18, 2006
Author(s)
Zhi Yang, Winnie K. Wong-Ng, James A. Kaduk, Qingzhen Huang, Lawrence P. Cook
This paper reports the results of the crystallography and crystal chemistry investigation of the (Ba1-xSrx)Y2 CuO5 ( green phase ) solid solution series by x-ray powder diffraction (XPD) and neutron powder diffraction (NPD) methods. The single phase region

Synthesis of Bioconjugated Magnetic Nanoparticles for Magneto-Raman Study

February 1, 2004
Author(s)
Guangjun Cheng, D B. Romero, D Dunmire, Angela R. Hight Walker
We are investigating the effects of an externally applied magnetic field on the structure and magnetic properties of biomolecules (DNA and proteins). A newly constructed, magneto-Raman confocal microscope system couples a cryo-magnet to a triple grating

Structural Study of an Unusual Cubic Pyrochlore Bi 1.5 Zn o.92 Nb 1.5 O 6.92

October 1, 2002
Author(s)
Igor Levin, T G. Amos, J Nino, Terrell A. Vanderah, C A. Randall, M T. Lanagan
Single-phase pyrochlore specimens of Bi 1.5Zn 0.92Nb 1.5O 6.92 were studied using combined electron, X-ray and neutron powder diffraction techniques. Rietveld refinements using neutron powder diffraction data confirmed an average pyrochlore structure A 2B

Sorptivity-Based Service Life Predictions for Concrete Pavements

September 1, 2001
Author(s)
Dale P. Bentz, M A. Ehlen, Chiara F. Ferraris, Edward J. Garboczi
The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze/thaw) into the concrete. With this in mind, a three-year research project, funded by the Federal

Electron Collision Data for Plasma-Processing Gases

October 1, 2000
Author(s)
Loucas G. Christophorou, James K. Olthoff
Low-temperature plasma applications require detailed understanding of the physical and chemical processes occurring in the plasmas themselves. For instance, as the push for smaller feature sizes and higher quality devices in the semiconductor industry has

Barium Hollandite-Type Compounds Ba x Fe 2x Ti 8-2x O 16 with x= 1.143 and 1.333

February 23, 1999
Author(s)
J. M. Loezos, Terrell A. Vanderah, A R. Drews
Experimental X-ray powder diffraction patterns and refined unit cell parameters for two barium hollandite-type compounds. Ba xFe 2xTi 8-2xO 16, with x = 1.143 and 1.333, are reported here. Compared to the tetragonal parent structure, both compounds exhibit
