In later PR-TRMC measurements, the after-pulse relaxation of the microwave conductivity itself in pure gases was monitored with nanosecond time-resolution and this provided a more detailed, quantitative method of monitoring electron thermalization. Of particular importance was a detailed study of thermalization in helium, which could be used to test the predictions of different theoretical treatments for this well-characterized gas. Detailed thermalization data were also obtained for oxygen, for which the concurrent three-body attachment process provides an interesting complication. The dramatic influence of small concentrations of water vapor on the thermalization process was also demonstrated for samples of dry and humid air. ° The (unexpectedly) high thermalization... 

Earlier TG/MS data for residual moisture in freeze-dried biological products were obtained by the continuous monitoring method of Chiu and Beattie using a DuPont 990 thermal analysis system interfaeed with a glass tee to a DuPont 21-104 mass spectrometer and the methodology... 

The performance of clay-based construction products, e.g., bricks and roofing tiles, can be monitored using thermal methods. The types of raw materials, viz., clay and accessory minerals, and their reactions that occur during the firing process and the durability of clay products can be examined through the application of DTA, TG, TMA, and dilatometric methods. This is particularly important for quality control as physical and chemical behaviors are dependent on the raw material characteristics, e.g., composition, particle size, and morphology.
