The reaction of Pd(cod)Cl-2 (cod = cycloocta-1,5-diene) with 1 and 2 equiv. of rac-diphenyl[2.2]paracyclophanylphosphine, rac-PPh2(C16H15), affords the dimer Pd{PPh2(C16H15)}Cl-2 (1) and the square-planar complex trans-Pd{PPh2(C16H15)}(2)Cl-2 (2), res ...
HMT-C11 belongs to the family of adducts formed by the cocrystallization of N-4(CH2)(6) molecules ( hexamethylenetetramine or HMT) and aliphatic dicarboxylic acids HOOC(CH2)(n-2)COOH with 5 less than or equal to n less than or equal to 13 (Cn). The adducts ...
In this paper we give an overview of our work on an asynchronous BCI (where the subject makes self-paced decisions on when to switch from a mental task to the next) that responds every 1/2 second. A local neural classifier tries to recognize three differen ...
We present the results of a study of the dynamics of trions and excitons in a CdTe modulationdoped quantum well as a function of temperature in the low-density regime. Using three-pulse four-wave mixing technique, we show that, at low temperature, these qu ...
With specially designed micromechanical cantilevers we have measured the magnetization of two-dimensional electron systems formed in an integrated single-layered AlGaAs/GaAs heterojunction. In samples of different mobility we have observed sawtooth-like de ...
Synthesis of Pd nanoparticles with controlled size (d(Pd) = 1-3.6 nm) was carried out within the pores of the mesoporous HMS and SBA-15 silicas. Pd was ion-exchanged on non-calcined silicas, prepared by solvent extraction of the templates. A high concentra ...
The spectral autocorrelation for a set of over 400 near-field photoluminescence spectra of a narrow quantum well has been evaluated. It is compared with a microscopic model of an exciton in a disorder potential. The analysis provides strong evidence for qu ...
A neutron-scattering study of nonsuperconducting La2-xSrxCaCu2O6 (x=0 and 0.2), a bilayer copper oxide without CuO chains, has revealed an unexpected tetragonal-to-orthorhombic transition with a doping dependent transition temperature. The predominant stru ...
Near-field photoluminescence spectra of a single quantum well dominated by emission from localized excitons are subjected to a statistical analysis of the two-energy autocorrelation function, This analysis is compared to a theoretical model of the exciton ...
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 ...
