Synthesis and Characterization of Bio‐based Polybenzoxazine Hybrids From Vanillin, Thymol, and Carvacrol

Chemistry – An Asian Journal, EarlyView.
In this study, we synthesized hybrid benzoxazines from the bio‐phenolic compounds—vanillin, thymol, and carvacrol— Jeffamine D‐230, and paraformaldehyde through a Mannich reaction. The thermal polymerizations of the hybrid benzoxazines were analyzed using differential scanning calorimetry (DSC).

Understanding and Enhancing the Cycling Stability of Layered Double Hydroxides with Intercalated Ferrocene Anions for Energy Storage Application

Batteries &Supercaps, EarlyView.
In this work, mono‐ and divalent ferrocene carboxylates are successfully intercalated in the layered structure of Mg2Al(OH)6 to form the redox active materials MgAl‐FcMono and MgAl‐FcDi. Initial limitations concerning the cycling stability of electrodes based on these materials in aqueous electrolyte are overcome by the utilization of ionic liquid ...

The Value Chain of Sustainable Dual Carbon Sodium Ion Capacitors

Batteries &Supercaps, EarlyView.
Sodium‐ion capacitors (SICs) bridge the energy‐power gap between batteries and supercapacitors, offering sustainable and scalable energy storage solutions. This review provides a 360‐degree perspective on SIC technology, covering material choices, presodiation strategies, manufacturing challenges, applications and life cycle assessment to ensure ...
