Curing kinetics of commercial polycarbosilane have been measured using differential scanning calorimetry in air between 140 and 220 degrees C. It was found that the total heat of curing increases linearly with temperature. At constant temperature, the rate ...
In addn. to online detection of events in biotechnol., calorimetry could be used to control processes. In the latter case, a correct and instantaneous heat signal must be available. This would be possible only if a correct evaluation of baseline evolution ...
Chemostat cultures of an aerobic fermenting yeast (Saccharomyces cerevisiae) and an aerobic respiring yeast (Kluyveromyces fragilis) were grown under dual C + N limitation in an isothermal reaction calorimeter. The dual limitations resulted in uncoupled ox ...
High-temperature calorimetry experiments show that the isobaric heat capacity (C(p)) of minerals increases in an anomalously rapid way when the melting point is approached. These premelting effects can begin a few hundred degrees below the melting point, a ...
A simple definition of the energetic growth efficiency both in terms of enthalpy and free energy is given and discussed. In cultures growing by respiratory catabolism, these efficiencies may conveniently be obsd. online by isothermal reaction calorimetry. ...
A review with 75 refs. of calorimetric techniques used and results obtained in calorimetric expts. aimed at developing quant. relation between heat release and other important process parameters for potential use in monitoring and controlling tech. bioproc ...
Isothermal reaction calorimetry was employed on the bench scale to measure the enthalpy efficiency and O2 efficiency of growth of several microbial strains cultured on a range of substrates with varying degrees of redn. The obsd. values of these energetic ...
