Rate coefficients for the OD reaction were also determined over a range of temperatures (262−374 K) at 100 Torr (He). The OD rate coefficients were ∼15% greater than the OH values and showed similar temperature dependent behavior with k2(T) = (7.52 ± 0.44) × 10−13exp[−(476 ± 20)/T] and k2(296 K) = (1.53 ± 0.15) × 10−13 cm3 molecule−1 s−1. The rate coefficients for reaction 1 were also measured using a relative rate technique between 296 and 375 K with k1(296 K) measured to be (1.22 ± 0.1) × 10−13 cm3 molecule−1 s−1, in agreement with the PLP−LIF results. In addition, the 296 K rate coefficient for the O3 +( E)CF3CHCHCF3 reaction was determined to be <5.2 × 10−22 cm3 molecule−1 s−1. A theoretical computational analysis is presented to interpret the observed positive temperature dependence for the addition reaction and the significant decrease in OH reactivity compared to the (Z)-CF3CHCHCF3 stereoisomer reaction. The estimated atmospheric lifetime of (E)-CF3CH CHCF3, due to loss by reaction with OH, is estimated to be ∼90 days, while the actual lifetime will depend on the location and season of its emission. Infrared absorption spectra of (E)-CF3CHCHCF3 were measured and used to estimate the 100 year time horizon global warming potentials (GWP) of 32 (atmospherically well-mixed) and 14 (lifetime-adjusted).</p>Cooperative bi-exponential decay of dye emission coupled via plasmons2018-07-05T20:11:10-05:00https://digital.library.unt.edu/ark:/67531/metadc1212017/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1212017/"><img alt="Cooperative bi-exponential decay of dye emission coupled via plasmons" title="Cooperative bi-exponential decay of dye emission coupled via plasmons" src="https://digital.library.unt.edu/ark:/67531/metadc1212017/thumbnail/"/></a></p><p>This article demonstrates that the relaxation in the sub-radiant system leads to the population of the sub-radiant states by dephasing the super-radiant Dicke states giving rise to the bi-exponential decay in agreement with the experiments.</p>Quantum walks of two interacting particles on percolation graphs2018-03-29T22:10:46-05:00https://digital.library.unt.edu/ark:/67531/metadc1115859/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1115859/"><img alt="Quantum walks of two interacting particles on percolation graphs" title="Quantum walks of two interacting particles on percolation graphs" src="https://digital.library.unt.edu/ark:/67531/metadc1115859/thumbnail/"/></a></p><p>This paper addresses the dynamics of two indistinguishable interacting particles moving on a dynamical percolation graph.</p>Development and Use of a Switchgrass (Panicum Virgatum L.)
