The present review showed the importance of using the differential scanning calorimetry (DSC) in the evaluation of the hair damage. Many hair-straightening treatments necessarily involve a heating process, which even at low temperatures can cause dam

In the search for alternatives to traditional paint systems solvent-based, the curing process of polymer coatings by ultraviolet light (UV) has been widely studied and discussed, especially because of their high content of solids and null emission of

The mathematical evaluation of the activation energy, E, of non-isothermal degradation reactions is usually made using the Ozawa/Flynn–Wall isoconversion principle and involves the numerical resolution of a set of integrals without closed form solu
