An effective and facile injection strategy based on iodine redox chemistry is proposed to restore lost lithium component in spent LiFePO₄ battery.

In-situ spectroscopic characterization is conducted to unveil the underlying redox mechanism of iodine-mediated lithium reactivation, elucidating its impact on both the cathode and anode.

Regenerated LiFePO₄ cells exhibit ~ 7% capacity recovery, fast charge transfer behavior, and extended cycle life beyond 300 cycles at 1C, outperforming conventional direct recycling methods while maintaining superior cyclic stability.

Structure–property relationship of self-assembled monolayers (SAMs) is thoroughly elucidated, including chain length, anchoring groups, linker groups, terminal functional groups, and packing density—and their resulting physical and electrochemical properties (e.g., wettability, adhesion, and electronic characteristics).

The mechanism of SAMs on promoting the performance of inverted perovskite solar cells is discussed from the perspective of energy-level alignment, defect passivation, carrier transfer dynamics, and inhibition of ion migration.

Perspectives and challenges of SAMs are proposed, highlighting promising directions in developing new in situ characterizations, advanced molecular designs, and optimized deposition strategies for large-scalable fabrication.

A bioinspired design mimicking the cooperative vascular–neural networks in biological tissues was proposed to guide the development of conductive hydrogels.

Solvent- and thermally induced structural reorganization enhances poly(vinyl alcohol) crystallinity and poly(3,4-ethylenedioxythiophene) chain alignment, yielding a synergistic combination of high tensile strength (10.72 MPa) and ultrahigh conductivity (452.75 S m⁻¹).

The hydrogel ensures stable electrical conduction and reliable multimodal sensing, enabling accurate and electromyographic/electrocardiographic monitoring and 99.54% gesture recognition accuracy.

A ligand reshaped strategy is proposed to optimize the surface state of silver indiumgallium sulfide (AIGS) quantum dots (QDs) via a polyfunctional ligand,mercaptosuccinic acid.

Both donor–acceptor pair and non radiative recombination pathways are decreased afterpassivation, which leads to a notable narrowing full width at half maximum to 31 nm andan enhancement of photoluminescence quantum yield up to 89%.

The efficient and pure QD based light emitting diodes (QLEDs) exhibit a maximumpeak external quantum efficiency of 8.4%, representing the record performance of AIGS QLEDs.

Insightful discussion of the unique properties of perovskite materials in terms of optical, electrical, and ion migration properties, along with extensively analysis of different categories of perovskite materials for biomimetic synapses.

Comprehensive exploration of the structures and working mechanisms of perovskite synapses, emphasizing their transformative opportunities in neuromorphic vision computing.

Prospective outlook on the approach to the performance optimization methods of synaptic devices, covering material optimization, device structure design, and external physical signal regulation.

4-Fluoro-3-nitrophenylboronic acid, as an additive, has contributed to uniform N-/F-rich interphase layers at both electrodes of the lithium metal batteries.

Uniform interphase layers inhibited Li dendrite growth at Li-metal anode, and alleviated uncontrolled electrolyte decomposition and active species loss at the LiFePO₄ (LFP) cathode.

Li ||Li cells demonstrate enhanced plating/stripping reversibility of >700 h at 1 mA cm⁻² and 0.5 mAh cm⁻², while Li ||LFP cells can be stably cycled for over 500 cycles at 3C rate with a capacity retention of 99.9%, simultaneously maintaining >99.9% coulombic efficiencies.

High-performance semitransparent organic photovoltaics (STOPVs) with decreased electrical loss were fabricated via introducing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) to electron transport layer (ETL).

LiTFSI interacts with ETL material PDINN and enhanced π-delocalization in PDINN, which is beneficial to conductivity and thereby electron collection range.

LiTFSI-doped PDINN-based STOPVs show an improved power conversion efficiency of 14.3%, average visible transmittance of 29.0%, and light utilization energy of 4.15%, which is among the highest values of optical structure-free STOPVs.
