Controlling active transport of water through membrane channels is essential for advanced nanofluidic devices. Despite advancements in water nanopump design using techniques like short-range invasion and subnanometer-level control, challenges remain facilely and remotely realizing massive waters active transport. Herein, using molecular dynamic simulations, we propose an ultrahigh-flux nanopump, powered by frequency-specific terahertz stimulation, capable of unidirectionally transporting massive water through asymmetric-wettability membrane channels at room temperature without any external pressure. The key physics behind this terahertz-powered water nanopump is revealed to be the energy flow resulting from the asymmetric optical absorption of water.

Hybrid TiO ₂ /ZIF-8 nanobeads have been prepared by decorating the surface of mesoporous TiO ₂ spheres with ZIF-8 nanoparticles and enhanced photocatalytic activity of Cr( vi ) reduction than pristine TiO ₂ beads due to their hybrid nanostructures.

Lithium–sulfur batteries face challenges such as the polysulfide shuttle effect and sluggish redox kinetics, leading to poor sulfur utilization and limited cyclic stability. Herein, an oxygen‐doped engineering approach is presented to achieve pillar‐free interlayer extension of MoS ₂ (E‐MoS ₂ ) for lithium polysulfide conversion. E‐MoS ₂ features expanded interlayer spacing (from 0.63 to 0.95 nm), improved conductivity, and an optimized Mo d band center, which collectively enhances polysulfide conversion efficiency. Consequently, cathodes with E‐MoS ₂ deliver a capacity of 638 mAh g ⁻¹ after 600 cycles at 2 C (0.046% decay/cycle) and an areal capacity of 12.0 mAh cm ⁻² under practical conditions (12 mg cm ⁻² S loading, E/S = 4 µL mg ⁻¹ ). This work highlights interlayer engineering as a key strategy for optimizing MoS ₂ catalysts in conversion‐type batteries.

With the advance of nanotechnology, the past couple of years have witnessed the fast development of quasi two-dimensional (2D) halide perovskites, which exhibit outstanding long-term stability against moisture and heat, compared with their three-dimensional (3D) counterparts. As one of the most common structures in 2D halide perovskites, quasi-2D Dion–Jacobson (DJ) perovskites show multiple-quantum-well structures with n layers of [BX₆]⁴⁻ octahedral inorganic sheets sandwiched by two layers of diammonium spacers, thus exhibiting superior structural stability due to the elimination of van der Waals gaps. Thanks to the achievement of high power conversion efficiency accompanied by impressive stability, quasi-2D DJ perovskite solar cells (PSCs) have recently drawn extensive attention in the field. This review first introduces the fundamental understanding of quasi-2D DJ halide perovskites, including their superior stability, high exciton binding energy, and compositional flexibility and tunable properties. We then summarize detailed strategies to prepare high-quality quasi-2D DJ perovskites for PSCs, encompassing compositional engineering, solvent engineering, additive addition, and annealing processes. Moreover, the surface/interface modification and 2D–3D hybrid perovskite heterojunction are also discussed, for providing strategies to optimize the fabrication of quasi-2D DJ PSCs. Lastly, current challenges and perspectives toward the future development of quasi-2D DJ perovskites for photovoltaics are outlined.
