Two samples of the same product, frozen in two different ways, were subsequently freeze-dried in the same manner (Figure 1). The first sample (Figure lA) was subjected to slow freezing with no surfusion phenomenon. The thermal recording curve shows a plateau at the temperature of 0°C, corresponding to deepfreezing of the sample, then a steady decrease in temperature. 

In this study, it has been shown that (i) the brightness of a synchrotron beam is necessary for the study of dispersed systems and (ii) only the coupling of time-resolved XRD at both small and wide angles with DSC allows the interpretation of complex structural and thermal recordings observed during milk-fat globules crystallization. 

Dextrin is extensively used in the manufacture of photosensitive materials (developers, thermal recording materials, optical information recording media, and photohardenable printing and transfers). Among other uses, dextrin diminishes the absorptivity and flabbiness of diazo copying...

Phthalide derivatives are of major importance in the dye industry, particularly in the area of recording material color formers. Pressure-sensitive carbonless copy paper and thermal recording paper are typical applications. Five principal structural classes have been developed extensively the xanthene dyes (fluorans (208)), 3,3-diarylphthalides (209), spirofluorenes (210), 3,3-bis(di-arylethylene)phthalides (211), and 3-substituted phthalides <84Mi 208-03>. Some of these structures are common to many familiar acid/base indicators, dyes, biological stains, or laser dyes such as fluorescein (212) and phenolphthalein (213) ,...

Denature the samples by placing each slide on the heat block for 3 min, slide-side down. The heat block temperature and time for this denaturation step were determined by performing mock denaturations with slides to which were affixed thermal recording strips. Under these conditions the sample reaches a temperature of approximately 91°C.
