Conventional calorimetry has always the difficulty of choosing between near to equilibrium working conditions and high thermal
ramp rates. Thus, either the transport phenomena and sample homogeneities are good but the signals become weak due to thermal
losses, or the signals are sharp, but strong gradients across the sample lead to chemical and thermal heterogeneities. The
described pulsed fluidized bed technique, by strongly stirring the sample, allows good sample homogeneities even at high ramp
rates. Moreover, the permanently regenerated cover gas allows as well a good heat transfer towards the thermocouples as a
constant atmosphere composition leading to very precise onset temperatures.
1 Introduction Since the advent of the laser over sixty years ago, there has been intense interest in the quest to generate ultra-short laser pulses in the picosecond and femtosecond time scale. Nowadays great efforts have been devoted to generate
Aim of this study is to investigate, by use of the pulse radiolysis technique, the mechanism of oxidation of trypthophan by OH and secondary inorganic radicals. Parallel pulse radiolysis studies were, performed on tryptophan and 1-formyltryptophan. The results seem to indicate that the most important attack on tryptophan residues is an one-electron oxidation. These results are compared with other data from the literature and a general discussion is made.
