in the present work, the interaction of three water soluble porphyrins, tetra (p-trimethyle) ammoniumphenyl porphyrin iodide (tapp) as a cationic porphyrin, tetra sodium meso-tetrakis (p-sulphonatophenyle) porphyrin (tspp) as an anionic porphyrin and manganese tetrakis (p-sulphonato phenyl)porphinato acetate (mntspp) as a metal porphyrin, with dna have been studied by isothermaltitration microc...

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...

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 ...

This booklet provides an introduction to the concepts of Differential Scanning Calorimetry (DSC). It is written for the materials scientist unfamiliar with DSC. The differential scanning calorimeter (DSC) is a fundamental tool in thermal analysis. It can be used in many industries – from pharmaceuticals and polymers, to nanomaterials and food products. The information these instruments generate...
