Assemblies of CdS quantum particles studied by the attenuated low energy photoelectron spectroscopy

Article Abstract:

The direct observation of collective electronic properties in assembled CdS quantum particles (QPs) arranged in periodic layers in reported. The attenuated low energy photoelectron spectroscopy (A-LEPS) method is used to study the electronic properties of the QPs and the results indicate that A-LEPS method provides information about the populated electronic states of the QPs, and also provides a clear signature for the interactions between CdS QPs in the film.

A liquid water model: Density variation from supercooled to superheated states, prediction of H-bonds, and temperature limits

Article Abstract:

The expressions for density and fraction of hydrogen-bonding and hydrogen atoms are derived and applied from supercooled to superheated states of liquid water. The anomalous density variation (around 4 degree Celsius) with temperature is explained solely on the basis of hydrogen-bonding and non-hydrogen-bonding hydrogen atoms in the liquid.
