Engineering Metastability in Atomic Layer Deposition: Polymorph and Valence Control

Small, EarlyView.
This work presents strategies for stabilizing two types of metastable phases: structural polymorphs and multivalence states via ALD. These approaches focus on lowering the energy barriers required for metastable phase formation, enabling access to metastable states beyond the thermodynamic limits imposed by the low‐temperature conditions of ALD.

A Novel Supercapacitor with Integrated Photosensitive Electrode to Enhance Its Capacitance Under Solar Light

Small, EarlyView.
In this research we demonstrated that the energy density of supercapacitors can be enhanced at about 50% by generating extra charge through the use of a photosensitive cell coupled to the supercapacitor estructure. ABSTRACT This research reports a supercapacitor (SC) made with a photosensitive electrode (composed of LaFe0.94V0.01Mn0.05O3 (V‐LFO ...

Encapsulating Zinc Powder in MXene/Silk Scaffolds with Zincophilic‐Hydrophobic Polymer for Flexible Zinc‐Ion Batteries

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
This work develops flexible zinc‐ion batteries (FZIBs) using a zincophilic/hydrophobic polymer (thermoplastic polycarbonate‐based polyurethane, TPCU) to protect Zn powder anodes and MXene/Silk (MXS) as flexible current collectors. The designed TPCU‐ZnP@MXS structure enables uniform Zn deposition, yielding dendrite‐free anodes with stable cycling ...
