A highly conserved G-quadruplex in STING promoter region has been verified and precisely targeted by CRISPR-mediated specificity, which can restrain STING expression and restore Aβ phagocytic capacity of microglia for treatment of Alzheimer's disease.

The doping of rare-earth element into NiFe-MOFs regulated the electronic property of active sites and optimized the adsorption energy of reaction intermediates, leading to superior performance for both alkaline freshwater and seawater splitting.

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.
