Reversible Metamorphosis of a Conjugated Polymer Induced by Photoexcitation

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
Photon absorption in conjugated polymers induces a persistent, reversible transformation in their optoelectronic and structural properties. At elevated temperatures, photoexcitation alters the molecular conformations and (re)organization of polymer molecules within low‐viscosity matrices, resulting in a persistent “photomemory” effect with blue‐shifted

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, Volume 16, Issue 10, 11 March 2026.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.
