Thermal Degradation an overview ScienceDirect Topics

The thermal degradation behavior of PHB has been discussed in many reports. Random chain scission by β-elimination has been considered the dominant mechanism based on the presence of crotonic acid and oligomers with a crotonate end-group at almost all chain ends of the pyrolysis products [23–26].Kawalec et al. [27] proposed an E1cB mechanism proceeding via α-deprotonation by a

Thermal coal exposure Sustainable investing

Thermal coal exposure measures the proportion of a company’s operations that is linked to the mining, processing or sale of this common but increasingly environmentally unacceptable fossil fuel. Thermal coal, also known as ‘steaming coal’ or just ‘coal’, is widely used as the principle means of generating electricity in much of the world.
