Using electrospun high-strength carbon nanofibers as the aerogel scaffold, high loading of polyaniline in the aerogel was achieved through seed polymerization, forming the core–shell structure fibers and simultaneously connecting the fibers as a stable conductive network.

Combining carbon-based materials with conductive polymers like polyaniline significantly improves shielding performance, achieving electromagnetic interference shielding efficiency of up to 84.5 dB and SE d⁻¹ values greater than 791.2 dB cm³ g⁻¹. Flame retardancy reduces PHRR by 65.8%, and thermal insulation with low thermal conductivity of 0.104 W m⁻¹ K⁻¹.

As-prepared CPS-Ni||Zn batteries exhibit simultaneously ultrahigh energy and power densities.

The innovative synthesis of pure green FAPbBr₃ nanocrystals at room temperature was exploited by employing aromatic amine ligands to refine the perovskite nanocrystals with high quality and excellent optoelectronic properties.

The proposed ligand engineering strategy firstly realized the suppression of emission thermal quenching effect in the organic-inorganic hybrid FAPbBr₃ nanocrystals.

It was demonstrated that the FAPbBr₃ based light-emitting diodes achieved a room temperature external quantum efficiency (EQE) of 21.9% at the luminance of 1580 cd m^-2, and only presented less than 10% loss in EQE at a higher temperature of 343 K.

This review highlights the gradient variations in the structural composition of musculoskeletal tissues and comprehensively examines recent progress in the fabrication and application of biomimetic gradient scaffolds for musculoskeletal repair.

By modulating the crystalline properties of the active layer with dual donors, the efficiency of organic solar cells reaches 19.23%.

The introduction of PTzBI-dF suppresses the accumulation of traps and charge recombination, allowing ternary devices to maintain 82% of their initial power conversion efficiency (PCE) after illumination for 800 h.

Demonstrate that the key factor to determine the activity of reconstructed surfaces is the surface chemistry, instead of reconstruction degree using the popular perovskite LaNi_1-xFe_xO₃ oxides as model materials.

Fe content can influence both the surface reconstruction degree, the activation degree, and the activity of reconstructed surfaces.

The oxygen evolution reaction activity of reconstructed catalysts is primarily governed by the chemistry of the reconstructed surface species.
