Calorimetric study of a halogen-bridged MMX chain complex having alkyl chains, Pt2(n-PrCS2)(sub 4)I(n-Pr=propyl group)
Article Abstract:
The heat capacity of Pt2(n-PrCS2)(sub 4)I was measured with adiabatic calorimetry to characterize the phase transitions detected in the transport and the magnetic studies. The magnitude of entropies of transitions show that the model of structural disorder constructed for Pt2(n-BuCS2)(sub 4)I(super 22) works quite well for Pt2(n-PrCS2)(sub 4)I, though the appearance of the disordering process such as the order of phase transition is largely different in two compounds.

Oxygen reduction kinetics in low and medium temperature acid environment: correlation of water activation and surface properties in supported Pt and Pt alloy electrocatalysts
Article Abstract:
Kinetics of oxygen reduction reaction on supported Pt and several Pt alloy electrocatalysts (PtCo/C and PtFe/C) are investigated in terms of the effect of alloying on the initiation and extent of surface oxide formation. The results are discussed in the context of a PEM fuel cell operating in the low to medium temperature range (70-120 degree C) and humidity variation (100 to10 percent).

Alkyl group as entropy reservoir in an MMX chain complex, Pt2(n-PenCs2)4I
Article Abstract:
Heat capacity of halogen-bridged one-dimensional binuclear metal complex having four n-pentyl groups, Pt2(n-PenCS2)4I, is measured by adiabatic calorimetry. A first-order phase transition is observed at 207.4 K when measurement is made after cooling from room temperature.
