The water‐exchange mechanism of [UO2(OH2)5]2+ has been reinvestigated by using ab initio molecular orbital (MO) methods. The geometries and the vibrational frequencies were computed with CAS‐SCF(12/11)‐SCRF and CAS‐SCF(12/11)‐PCM methods, which take into a ...
The C2-sym. electron-poor ligand (R)-BINOP-F (4; (R)-2,2'-[bis(pentafluorophenyl)phosphinoxy]-1,1'-binaphthalene) was prepd. by reaction of (R)-BINOL ((R)-1,1'-binaphthalene-2,2'-diol) with bromobis(pentafluorophenyl)phosphine in the presence of NEt3. The ...
We present a model for the disorder of the heterointerfaces in GaAs quantum wells including long-range components like monolayer island formation induced by the surface diffusion during the epitaxial growth process. Taking into account both interfaces, a d ...
V groove GaAs/AlGaAs quantum wires are investigated by spatially resolved photoluminescence spectroscopy using a low-temperature scanning near- field optical microscope. The spectra along the wires feature several sharp emission lines, which are understood ...
The efficiency of dissocn. of macromol. ions during the capture of electrons in the ion trap of the ICR mass spectrometer is significantly enhanced by using an improved system of injection of low-energy electrons. The fragmentation time for an ion ensemble ...
We consider the problem of minimization of generalized Buchi automata. We show how to extend fair simulation and delayed simulation to the case where the Buchi automaton has multiple acceptance conditions. For fair simulation, we show how to efficiently co ...
Relaxor ferroelectric thin films exhibit a drastic reduction in the dielectric constant and associated properties in the thin film form, even for thicknesses in the micron range, which are essentially infinity for the size effects typically investigated in ...
The resonant Rayleigh scattering dynamics of excitons in single GaAs quantum wells is investigated. The deviation of the measured intensity from the ideal ensemble average is analyzed as a function of the speckle ensemble size. The influence of the amplitu ...
The dynamics of resonant Rayleigh scattering (RRS) from excitons localized in a disorder potential with large monolayer islands is investigated theoretically and experimentally. Experimentally, the coherent RRS dynamics from GaAs single quantum wells (SQWs ...
Patients with hemispatial neglect restricted to near (within reaching distance) or to far space (beyond reaching distance) have been described. This constitutes a double-dissociation considered by current neurocognitive thinking as compelling evidence for ...
