We develop a novel membrane electrolyte comprising h-BN-doped PEO modified PVDF-HFP-nanofibers with high ionic conductivity (3.3 × 10⁻⁴ S cm⁻¹) and Li⁺ transference number (0.74), endowing solid LiFePO₄//Li batteries with excellent cyclability.

A photo-redox stereodivergent atom transfer radical addition of α-functionalized alkyl iodides to alkynes allows the selective and efficient synthesis of both E- and Z-iodoalkenes.

The synergetic effect between abrupt spin crossover and fluorescence is observed for the first time in an iron(III) complex.

This work introduces a rare example of CO₂R-to-CO coupled with 2e⁻WOR-to-H₂O₂, giving a total energy efficiency of 34%.

Mo₂C/MoS₂ heterostructure catalysts with hydrophilicity/aerophobicity are rapidly synthesized via carbothermal shock, demonstrating the accelerating alkaline HER kinetics.

Efficient indolocarbazole based blue thermally activated delayed fluorescence emitters with aggregation-induced emission are presented, affording OLEDs with a high external quantum efficiency of 29.9%.

An ultrathin polymer electrolyte with superior ionic conductivity and stable electrolyte/electrode interfaces enables a high-loading Li/NCM811 cell with a capacity retention of up to 71% after 400 cycles at a high cut-off voltage of 4.5 V.

A molecule-based ferroelectric [(CH₃)₃NCH₂CH₂Br][GaBr₄] (1), with a d₃₃ value of 331 pC N⁻¹, was synthesized. The power density of the 1@S-PDMS piezoelectric sensor, featuring optimized microstructures, is up to 490 μW cm⁻².

An unexpected finding of organic afterglow triggered by a paper (cellulose)-matrixed strategy was reported, which offers a novel host–guest afterglow system attributed to the Förster resonance energy transfer mechanism.

Eco-friendly chiral Mn complexes with Binapo ligands show red CPL (g_lum = 5.1 × 10⁻³) and efficient (EQE > 4% and g_EL = −8.5 × 10⁻³), outperforming many Pt and Ir-based devices, paving the way for sustainable materials.

The optical activity levels of metal centers govern the multi-mode emissions by manipulating the band alignments in hybrid metal halides.

Chain elongation and halogen substitution strategies are employed to synthesize low-melting-point bisphosphonium cation based metal halides, which can be used to fabricate highly stable glass scintillators.

A molecule-based ferroelectric, possessing the highest d₃₃ × g₃₃ values recorded to date, achieves a record power density of 120 μW cm⁻² in ferroelectric@PDMS PEGs, offering a viable method to enhance the electromechanical conversion coefficient.

A compact chemically driven [2]catenane rotary motor was designed for precise 360° unidirectional rotation utilizing a molecular pumping system. It operates in two phases: pumping induces a 180° rotation and discharging resets the motor.

A BODIPY-based silver cyclic trinuclear complex can be used as a photocatalyst for producing H₂O₂ either from pure water or from sea water with high photocatalytic activities in the absence of any additives.
