Differential scanning calorimetry temperature modulation

Also, literature reports new biodegradable poly(ethylene oxide)/cellulose, poly(ethylene oxide)/cellulose acetate, poly(ethylene oxide)/carboxymethyl cellulose, and poly(ethylene oxide)/cellulose ether blends obtained by solution casting and investigated by differential scanning calorimetry, temperature-modulated differential scanning calorimetry, and infrared spectroscopy techniques [134]. These studies indicate... 

Many publications present research that has been done on biodiesel from production to properties, such as oxidative stability, cold flow properties, and thermal decomposition, etc. [2, 11, 32, 39, 46]. Differential Scanning Calorimetry (DSC), Modulated Temperature-DSC and Pressure-DSC are among the techniques used to characterize biodiesel. Some of these techniques will be discussed in the following chapter.

Differential scanning calorimetry (DSC) was used in investigating the curing kinetics of the unsaturated polyester resin. For the study, we used a DuPont 1090 Thermal Analyzer, equipped with a 910 DSC Module. Indium was used for temperature and calorimetric calibrations, following the procedure described in the operating meinual of the instrximent. The experimental procedure employed is very similar to that described in the literature (8-13) cind we have discussed it elsewhere (14).

Dielectric relaxation, temperature-modulated differential scanning calorimetry (TMDSC), and H NMR spectroscopy (see Section 4.05.3.2.1) have been used to perform the dynamic characterization of fananserine 35. The use of these three different techniques gives a coherent set of information and allowed the authors to describe the dynamic properties over a wide range of frequencies and temperatures <2006MI798>.

Differential Scanning Calorimetry. DSC scans were made at 20°C min"1 on a Mettler TA300O system equipped with a DSC-30 low temperature module. Temperature calibration was done with a multiple Indium-lead-nickel standard. An indium standard was used for heat flow calibration. Thin shavings (ca. 0.5 mm thick) were cut with a razor blade from the cross-sectional edge of a plaque. These sections contained both surface and center portions.
