Bitumen microstructure by modulated differential scanning calorimetry

Theory and Practice of Modulated Temperature Differential Scanning Calorimetry

Differential scanning calorimetry of bacteria.

Thermograms obtained by differential scanning calorimetry of a range of bacteria of different heat resistances were compared. Equations were derived to calculate the rate at which the numbers of viable organisms in a calorimeter decline as the temperature is raised at a constant rate. Vegetative bacteria scanned at 10 degrees C min-1 showed multi-peaked thermograms with four major peaks (denote...

Differential Scanning Calorimetry of Whole

Cereal Chem. 66(4):317-320 The thermal properties of whole grain milled rice and milled rice flour samples. Gelatinization enthalpies were about 40% greater in whole grain were investigated by differential scanning calorimetry. Thermal curves rice compared to rice flour for each variety. Heating rate studies conducted were obtained on representative long, medium, short, and very low amylose on ...

Practical approach for measuring heat capacity of pharmaceutical crystals/glasses by modulated-temperature differential scanning calorimetry.

A practical protocol to obtain accurate heat capacity values of pharmaceutical compounds using modulated-temperature differential scanning calorimetry was established. Three pharmaceutical compounds, acetaminophen, indomethacin, and tri-O-methyl-β-cyclodextrin were used as model compounds. Powder samples did not produce reproducible results, presumably due to inclusion of gas in gap of powders ...

Separation of glass transition and crystallization in metallic glasses by temperature-modulated differential scanning calorimetry

The glass transition behaviour of the four metallic glasses La55Al25Ni20 , Zn65Mg35, and Nd60Fe30Al10 and Zr30Y30Al15Ni25 has been studied by temperature-modulated di€ erential scanning calorimetry (MDSC). It is clearly demonstrated that the glass transition can be separated from crystallization by MDSC. Two glass transitions have been observed for Zn65Mg35, Nd60Fe30Al10 and Zr30Y30Al15Ni25. Ow...
