Kinetic Energy Dose as a Unified Metric for Comparing Ball Mills in the Mechanocatalytic Depolymerization of Lignocellulose

Ball mill design in comparison to experimental parameters are among the most common characteristics in mechanochemical synthetic protocols. We used kinematic modeling to two ball mills operating under separate design principles to determine the energy dose as a mathematical function of the experimental parameters in this quest. We found linear correlations between yields of water-soluble products and energy dose for both ball mills by investigating the effect of energy dose on the extent of the mechanocatalytic depolymerization of lignocellulosic biomass. Interestingly, when a substrate layer is added to the grinding jar wall and/or grinding medium, a weak non-linear correlation between water-soluble products yield and energy dose is found. The new report focuses on the effectiveness of the energy dose as a unified metric in mechanochemistry in order to increase the understanding of reaction results obtained from various ball mills operating under different experimental conditions.

Catalytic Hydrothermal Depolymerization of DGEBA/EDA Epoxy Resin

In a stainless autoclave at temperatures of 270°C to 350°C in H2O medium, Hydrothermal depolymerization of DGEBA/EDA epoxy resin was carried out. SEM measured the epoxy resin composite made from glass fiber and the solid residue after reaction using catalytic hydrothermal depolymerization techniques.

Harnessing autocatalytic reactions in polymerization and depolymerization

A study of autocatalytic activity in polymeric systems, as well as kinetic control of polymeric compounds, synthesis of self-healing and self-immolative polymers, is among the next generation of materials for a sustainable circular economy, according to some.
