Free and zeolite-supported hexarhodium clusters with light impurity atoms
Article Abstract:
The effect of hydrogen, carbon, and oxygen impurity atoms on the structure of gas-phase and zeolite supported Rh6 clusters is discussed computationally with a gradient-corrected density functional method. Analyzation of the charge distribution of neutral and ionic clusters found that the C and O impurity atoms effect the electron density distribution on the Rh framework in different ways.

Molecular mobility in supercooled trehalose
Article Abstract:
The molecular mobility of amorphous anhydrous trehalose (C12H22O11) was investigated by means of temperature-modulated differential scanning calorimetry (TMDSC) and dielectric analysis (DEA).Several peculiar dynamic features of anhydrous supercooled trehalose, regarding both the main and secondary relaxation processes is revealed.
