High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

Advanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

Bio-coal as an alternative reducing agent in the blast furnace

, 2020
The steel industry is aiming to reduce CO2 emissions by different means; in the short-term, by replacing fossil coal with highly reactive carbonaceous material like bio-coal (pretreated biomass) and, in the longer term, by using hydrogen. The use of bio-coal as part of top charged briquettes also containing iron oxide has the potential to lower the ...

Synthesis of porous carbons for the fixing of cationic molecules in aqueous solution

Scientific African
In Africa, the calyxes of the Hibiscus sabdariffa are widely used to produce a fresh fruit juice, known in Benin as bissap. The stems from this production have no potential use and are therefore an environmental problem. The parietal composition of these

Thermal Stability of Aliphatic and Semiaromatic Polyamides: Tailoring the Choice of Isothermal Aging Temperature by Using Kinetic Models of Degradation

Journal of Applied Polymer Science, EarlyView.
Thermogravimetric analysis was performed to study the degradation of aliphatic and semiaromatic polyamides intended for the electrical insulation of future electric aircraft. Using the TGA results, the Flynn and Wall method and Toop's model, the activation energies for the degradation processes were calculated, and kinetic models of the degradation ...
