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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
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 ...

Harmonized Protocol for Segmentation of the Hippocampal Tail on High‐Resolution In Vivo MRI From the Hippocampal Subfields Group (HSG)

open access: yesHippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT The hippocampus is a heterogeneous structure with cytoarchitectonically distinct subfields that exhibit heterogeneous lifespan trajectories and are differentially susceptible to diseases. Advances in high‐resolution imaging have accelerated research on these structures, yet variability in segmentation protocols limits cross‐study comparability.

3D Cellular Automata of Polymer Structural Response to Solvent Quality

open access: yesMacromolecular Theory and Simulations, Volume 35, Issue 6, November 2026.
A minimal three‐dimensional cellular automaton captures solvent‐dependent polymer collapse, θ‐like scaling, swelling, and aggregation through simple local interaction rules. Radius‐of‐gyration scaling identifies the θ regime, while multichain simulations reveal that free chain ends and periodic self‐connection strongly govern structural reorganization,
