1 Armentrout, Peter B.Alkali metal cation interactions with 12-crown-4 in the gas phase: revisitedQuantitative interactions of alkali metal cations with the cyclic 12-crown-4 polyether ligand (12C4) are studied. Experimentally, Rb+(12C4) and Cs+(12C4) complexes are formed using electrospray ionization and their bond dissociation energies (BDEs) determined using threshold collision-induced dissoc...2012-01-01
2 Minteer, Shelley D.Bio-solar cells incorporating catalase for stabilization of thylakoid bioelectrodes during direct photoelectrocatalysisThylakoid membranes have been proposed for electrochemical solar energy conversion, but they have been plagued with short term instability. In this paper, thylakoid membranes extracted from Spinacia oleracea were physically adsorbed onto Toray paper electrodes with and without catalase, followed by ...2012-01-01

4 Armentrout, Peter B.Fragmentation reactions of thiourea- and urea-compounds examined by tandem MS-, energy-resolved CID experiments, and theoryFragmentation reactions of thiourea- and urea-compounds, which are promising reagents for chemical crosslinking (XL), are investigated in detail by collision-induced dissociation (CID) experiments in a quadrupole ion trap (QIT), energy-resolved CID experiments, and computational modeling. For this s...2012-01-01
5 Minteer, Shelley D.High performance glucose/O2 biofuel cell: effect of utilizing purified laccase with anthracene-modified multi-walled carbon nanotubesLaccase, a blue multicopper oxidoreductase enzyme, is a robust enzyme that catalyzes the reduction of oxygen to water and has been shown previously to perform improved direct electron transfer in a biocathode when mixed with anthracene-modified multi-walled carbon nanotubes. Previous cathode constru...2012-01-01
6 Armentrout, Peter B.Infrared multiple photon dissociation spectroscopy of protonated histidine and 4-phenyl imidazoleThe gas-phase structures of protonated histidine (His) and the side-chain model, protonated 4-phenyl imidazole (PhIm), are examined by infrared multiple photon dissociation (IRMPD) action spectroscopy utilizing light generated by the free electron laser FELIX. To identify the structures present in t...2012-01-01
7 Voth, Gregory AlanNanostructural organization in acetonitrile/ionic liquid mixtures: molecular dynamics simulations and optical Kerr effect spectroscopyIn this paper, the nanostructural organization and subpicosecond intermolecular dynamics in mixtures of acetonitrile and the ionic liquid (IL) 1-pentyl-3-methylimidazolium bis{(trifluoromethane)sulfonyl}amide ([C5mim][NTf2]) were studied as a function of concentration using molecular dynamics (MD) s...2012-01-01
8 Armentrout, Peter B.Role of methylation on the thermochemistry of alkali metal cation complexes of amino acids: N-methyl prolineQuantitative thermodynamic information is obtained from the study of the gasphase interactions of the alkali metal cation complexes of N-methyl proline (NMP) with Xe using a guided ion beam tandem mass spectrometer (GIBMS). Absolute bond dissociation energies (BDEs) of M+ = Li+, Na+, K+, and Rb+ to ...2012-01-01
9 Armentrout, Peter B.The simplest b 2 + ion: determining its structure from its energetics by a direct comparison of the threshold collision-induced dissociation of protonated oxazolone and diketopiperazineEnergy-resolved collision-induced dissociation of b2 + ions derived from protonated GGG and GAG are compared with that of protonated diketopiperazine (H+DKP).

11 Armentrout, Peter B.Thermodynamics and mechanisms of protonated diglycine decomposition: a guided ion beam studyWe present a full molecular description of fragmentation reactions of protonated diglycine (H+GG) by studying their collision-induced dissociation (CID) with Xe using a guided ion beam tandem mass spectrometer (GIBMS). Analysis of the kinetic energy-dependent CID cross sections provides the 0 K barr...2012-01-01
12 Armentrout, Peter B.Thermodynamics and mechanisms of protonated diglycine decomposition: a computational studyWe present a full computational description of the fragmentation reactions of protonated diglycine (H+GG). Relaxed potential energy surface scans performed at B3LYP/6-31G(d) or B3LYP/6-311+G(d,p) levels are used to map the reaction coordinate surfaces and identify the transition states (TSs) and int...2012-01-01
