Gas-phase fragmentation chemistry of protonated peptide ions

Bythell, Benjamin James (2007-12-10)

The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway c ...
Graphite intercalation compounds containing fluoroanions

Katinonkul, Watcharee (2007-10-18)

New chemical synthesis strategies have been investigated for the preparation of acceptor-type graphite intercalation compounds (GIC's) with fluoroanions in order to obtain new materials and to develop a better understand ...
Growth and characterization of wide–gap semiconducting oxide and chalcogenide thin films by pulsed laser deposition

Newhouse, Paul F. (2008-09-26)

The preparation and characterization of thin film oxides and chalcogenides by pulsed laser deposition (PLD) is presented. An overview of fundamental PLD concepts are presented and are followed by a description implemen ...
Growth, optical and magnetic behavior of YMn0.35In0.65O3 thin film

Mangalam, R. V. K.; Smith, Andrew E.; Boudin, S.; McLoughlin, C.; Subramanian, M. A.; Prellier, W. (American Institute of Physics, 2012-06-25)

The growth of YMn₀.₃₅In₀.₆₅O₃ thin films and their optical and magnetic behavior are reported. The YMn₀.₃₅In₀.₆₅O₃ thin film grows along the (0001) orientation with hexagonal structure similar to YMnO₃ on c-plane sapphir ...
High quantum-yield phosphors via quantum splitting and upconversion

Jeong, Joayoung (2007-12-06)

The Gd3+ ion has been used to induce quantum splitting in luminescent materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum splitting results from a two-step CRET between Gd3+ and Nd3+, firs ...
