One‐Step Solvothermal Synthesis of VS4@PC/rGO for High‐Performance Symmetric Supercapacitors

MetalMat, EarlyView.
VS4@PC/rGO ternary composites featuring a 3D skewer‐like structure have been synthesized via a facile one‐step in situ solvothermal approach. The assembled SSC device has a 1.4 V voltage window, achieves 46.1 Wh·kg−1 energy density at 374.8 W·kg−1, and demonstrates excellent long‐cycle stability.

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 ...

Synthetic Access to Alkali Metal Selenides via Ball Milling

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
We report the synthesis of alkali metal selenides through reactive ball milling under an argon atmosphere. This mechanochemical pathway is solvent‐free and can be performed at room temperature within minutes to hours. The synthesis of several sodium polyselenides (Na2Sen) and alkali metal selenides (A2Se, A = K, Rb, Cs) is investigated and the received

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 ...
