Molecularly Engineered Dual‐Crosslinked Polymer Dielectrics for 200 °C Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work establishes a molecular engineering strategy that constructs a robust dual‐crosslinked network in polymer nanocomposites, achieving a record‐high energy density of 5.17 J cm−3 with >90% efficiency at 200 °C. The multiscale‐validated design simultaneously enhances dielectric polarization and introduces deep electron traps, resulting in ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

New Biobased Polyester Polyols With Tunable Tg Values From 4‐Vinylguaiacol‐Derived Monomers

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Biobased low‐molecular‐weight polyesters were obtained by ROCOP of guaiacol‐derived epoxides with cyclic anhydrides. Varying the length of the acyl moieties on the epoxides and the cyclic anhydride structures, it is possible to tune the Tg's within an 80 ºC wide temperature range.

Active and Versatile ROP Aluminum Catalysts for the Controlled Limonene Oxide Polymerization and Copolymerization With Anhydrides

ChemCatChem, Volume 18, Issue 13, 14 July 2026.
Highly active aluminum catalysts for the ring‐opening copolymerization of LO and PA able to produce syndiotactic alternating copolyester within 3 h are presented. The role of DMAP as cocatalysts for the copolymerization is key and is involved in the opening of the anhydride, however, it blocks the catalytic activity for the LO ROP.
