exothermic peak
At absorpbed dose of 5 MGy the first exothermic peak is shifted by 15-20°C; in this case, both exothermic peaks coalesce and the oxidation can be considered as single-stage process starting at 110°C.
      
DSC thermograms for the curing of C1P and C2P with benzoyl peroxide (BPO) and NMA/MTHPA showed two distinct exothermic peak positions, Tp and T1p, due to the curing of esterified fraction and epoxy groups, respectively.
      
The results show that the supported Pd catalysts have two exothermic peaks at around 312 °C and 435 °C in the DSC thermograms, respectively, while the supported Pt catalysts have one exothermic peak at approximately 345 °C.
      
Using DSC, the exothermic peak due to precipitation from the supersaturated α-Al matrix was observed in the range of 200-250°C during continuous heating of atomized powder, and the size of the peaks increased with decreasing powder size.
      
Metastable phase with structure type of sigma phase (e.g., in Fe-Cr alloys) was observed in melt spun ribbons by rapid heating or annealing at temperatures below the first exothermic peak of DTA curve.
      
It is found that the phase transition occurs from the transparent-solution state of strong viscosity to a white solid state with exothermic peak.
      
Finally the DTA exothermic peak of kaolinite is interpreted in the light of the proposed general model.
      
An extra exothermic peak, which has not previously been reported, was observed at heating rates slower than 2.5K/min.
      
There was an exothermic peak at 252.89?°C referring to the thermal decomposition of azido group in differential scanning calorimetry (DSC) plot of EO03-3 and the glass transition temperature (Tg) was found at -47.13?°C.
      
On cooling, these gels exhibit an exothermic peak in micro-DSC and a depression in G'' and tan δ traces, evidencing a volume phase transition centered at ~20?°C.
      
Trans-polynorbornene isolated without 2,6-di-tert-butyl-4-methyl-phenol exhibited an exothermic peak accompanied by an slight increase in weight (1-2%), while samples treated with 2,6-di-tert-butyl-4-methyl-phenol do not show these features.
      
In the differential thermal analysis curve for polyethylene in a stream of oxygen an exothermic peak was obtained in the 180 °C region.
      
It was confirmed by infrared method that the exothermic peak is due to oxidation of vinyl type double bond in the polymer molecule.
      
All of them showed a sharp exothermic peak indicating crystallization temperature (Tc) followed by a sharp endothermic peak giving the value of melting temperature (Tm).
      
They exhibited a sharp exothermic peak indicating crystallization temperature (Tc) around 520 °C.
      
An exothermic peak appeared at about 30 °C in heating DSC thermograms for these gels.
      
The exothermic peak in the DSC curves was observed clearly for the specimen drawn up to λ=4 in the hot water bath at 80?°C, while the peak did not appear for the specimen drawn up to λ=4 at 62?°C.
      
An exothermic peak at -40 to -45°C and an endotherm at -25 to -15°C indicated that the majority of lipids were triacylglycerols (TAG).
      
Decomposition of this intermetallic phase during heating in the calorimeter gave rise to an exothermic peak at 680°C and led to precipitation of hcp Co, which converted to an fcc Co1 - xAlx solid solution on heating to 1000°C.
      
The kinetics of curing of the resins was studied by DSC analysis based on the exothermic peak due to the double bonds breaking to give crosslinked macromolecules.
