Application of Differential Scanning Calorimetry to the Characterization of Biopolymers

چکیده
Generally, polymers can be classified according to their thermal and mechanical properties into thermoplastics, thermosets and elastomers. Thermoplastics are amorphous or semicrystalline polymers that soft or melt during heating and solidify during cooling. The heating/cooling/heating process can be repeated without perceptible changes in thermal and mechanical properties of thermoplastics. Thermosets during heating undergo chemical changes and this process is irreversible. Elastomers can be vulcanized (cross-linked under assistance of heat, light, or special chemicals like sulfur, peroxides) that makes them reversibly stretchable for small deformations but vulcanization is the irreversible process.

Evaluation and Characterization of Free and Immobilized Acethylcholinesterase with Fluorescent Probe, Differential Scanning Calorimetry and Docking
Acetylcholinesterase (AChE) enzyme which catalyses the hydrolysis of choline esters, such as acetylcholine, is very important in nerve function. Previous structural studies showed the possible amyloid fibril formation on the AChE. Therefore it is important to understand interaction of ligands to prevent the formation of amyloid fibrils. The purpose of the present study was to char...
متن کاملApplication of the Avrami Theory for Wax Crystallisation of Synthetic Crude Oil
Wax crystallisation and deposition from offshore reservoirs have been causing serious problems such as plugged pipelines and reduced production flow rates. This issue is receiving more attention from the researchers and for commercial applications due to the shift in trend from using offshore production facilities to pipelines utilization. The aim of this study is the implementation of the Avra...
متن کاملSurveying the effects of silver nanoparticle on thermal properties of some calyx [4]arene compounds by Differential Scanning Calorimetry (DSC)
One of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. In this paper, the authors have studied thermal behaviour for Schiff base ligand and their synthesized Cobalt, Nickel complexes. In this method, the sample is opposed to a controlled temperature change and its physical properties. Here we studied melting point and Tg...
