 | Scarpulla, Michael | Air shear driven flow of thin perfluoropolyether polymer films | We have studied the wind driven movement of thin perfluoropolyether (PFPE) polymer films on silicon wafers and CNx overcoats using the blow-off technique. The ease with which a liquid polymer film moves across a surface when sheared is described by a shear mobility xS , which can be interpreted both... | Perfluoropolyether; Polymer films; Air shear; Shear mobility | 2003 |

 | Vardeny, Zeev Valentine | Excitons, polarons, and laser action in poly(p-phenylene vinylene) films | We have used a multitude of linear and nonlinear cw optical spectroscopies to study the optical properties of water precursor poly(p-phenylene vinylene) (PPV) thin films. These spectroscopies include absorption, photoluminescence, photoinduced absorption and their respective optically detected magne... | PPV films; Excitons; Laser action; Poly(p-phenylene vinylene) | 2003 |

 | Armentrout, Peter B. | Guided ion beam studies of the reactions of Nin+ (n=2-18) with O2: nickel cluster oxide and dioxide bond energies | The kinetic energy dependences of the reactions of Nin + (n=2 - 18) with O2 are studied in a guided ion beam tandem mass spectrometer. A variety of NimO2+, NimO+, and Nim+ product ions, where m<n, are observed, with the dioxide cluster ions dominating the products for all larger reactant cluster io... | Metal clusters; Nickel oxide; Nickel dioxide; Bond energies; Collision-induced dissociation; Exothermic reactions | 2003 |

 | Armentrout, Peter B. | Kinetic energy dependence of association reactions. A new thermokinetic method for large systems | The reactions of bare alkali metal ions (M+5Li+, Na+, or K+) with dimethoxyethane (CH3OCH2CH2OCH3 , (DXE) are studied using guided ion beam tandem mass spectrometry. The bimolecular reaction forms an associative M1(DXE) complex that is long-lived and dissociates back to the reactants. The kinetic en... | Collision-induced dissociation; Association reactions; Bond energies; Dimethoxyethane; Alkali metal ions | 2003 |

 | Bedrov, Dmitro; Smith, Grant D. | Molecular dynamics simulation study of elastic properties of HMX | Atomistic simulations were used to calculate the isothermal elastic properties for b-, a-, and d-octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX). The room-temperature isotherm for each polymorph was computed in the pressure interval 0≤p≤10.6 GPa and was used to extract the initial isot... | HMX; Elastic tensors; Isotropic moduli; Polymorphs; Isothermal compression; Lattice parameters | 2003 |

 | Armentrout, Peter B. | Thermodynamics of ammonia activation by iron cluster cations: guided ion beam studies of the reactions of Fen+ (n=2-10,14) with ND3 | The kinetic energy dependences of the reactions of Fen 1 (n52 - 10,14) with ND3 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. Dehydrogenation of ammonia to form FenND1 is found to be efficient and exothermic for n54 in agreement with previous FT-ICR stu... | 2003 |
