Ultrafast above-threshold dynamics of the radical anion of a prototypical quinone electron-acceptor.
Quinones feature prominently as electron acceptors in nature. Their electron-transfer reactions are often highly exergonic, for which Marcus theory predicts reduced electron-transfer rates because of a free-energy barrier that occurs in the inverted region. However, the electron-transfer kinetics that involve quinones can appear barrierless. Here, we consider the intrinsic properties of the par...
متن کاملChannel-closing-induced resonances in the above-threshold ionization plateau
Multiphoton resonances with ponderomotively upshifted Rydberg states are believed to have dramatic effects on the plateau of high-order above-threshold ionization. For short pulses and intense laser fields, individual Rydberg states lose their physical significance. Under these conditions, on the basis of experimental and theoretical investigation of the dependence of the photoelectron spectra ...
متن کاملDynamics of a random laser above threshold.
We have performed enhanced backscattering experiments in a high gain random laser, under circumstances where a stationary theory predicts the laser intensity to diverge. Above the laser threshold the observed backscatter cone changes only gradually, not showing any signs of the divergence. We present measurements and theory-generalized laser equations with a diffusive transport term for pump an...
متن کاملImmunochemical Identification of Coenzyme Q0-Dihydrolipoamide Adducts in the E2 Components of the -Ketoglutarate and Pyruvate Dehydrogenase Complexes Partially Explains the Cellular Toxicity of Coenzyme Q0*
Coenzyme Q0 (Q0), a strong electrophile, is toxic to insulin-producing cells. Q0 was incubated with rat and human pancreatic islets and INS-1 insulinoma cells, and its attachment to cellular proteins was studied with Western analysis using antiserum raised against the benzoquinone ring structure of ubiquinone (anti-Q). Q0 covalently bonded to two proteins, one of 50 kDa and another of 70 kDa. B...
متن کاملCavity Solitons in Driven VCSELs above Threshold
CSs have been theoretically predicted and recently experimentally demonstrated in broad area, vertical cavity driven semiconductor lasers (VCSELs) slightly below the lasing threshold. Above threshold, the simple adiabatic elimination of the polarization variable is not correct, leading to oscillatory instabilities with a spuriously high critical wave-number. To achieve real insight on the compl...
