Quantum-state-resolved CO2 scattering dynamics at the gas-liquid interface: Incident collision energy and liquid dependence

Article Abstract:

Quantum-state-resolved dynamics at the gas-liquid interface are determined by collided supersonically cooled molecular beams of CO2 with freshly liquid surfaces in a vacuum and translational, rotational and vibrational state distributions of both incident and scattered fluxes are measured by high-resolution direct infrared absorption spectroscopy. The major result is the clear presence of nonequilibrium distributions for the scattered CO2 over a wide range of collision energies and gas-liquid surfaces.

Comparative examination of the stability of semiconductor quantum dots in various biochemical buffers

Article Abstract:

Buffers used for the indirect immunofluorescence labeling of cells were tested with several fractions of the size-selective precipitation of thioglyconic acid (TGA) and mercaptopropionic acid (MPA)- stabilized particles were mixed with different buffers that had defined concentration. The results show the possibility of the use of water-soluble, thiol-capped QDs for immunofluorescence labeling using the commonly used buffers.

Comparison pf photophysical properties of the hemicyanine dyes in ionic and nonionic solvents

Article Abstract:

Steady -state and time-resolved fluorescence behaviors of hemicyanine dye molecules are examined using ionic and nonionic solvents. The results show that the fluorescence quantum yield increases with increase in solvent viscosity and in ionic liquid the fluorescence peak of the hemicyanine dye shifted with change in excitation wavelength.
