Molecule-specific adsorption offers an efficient approach for target molecule purification from complex mixtures that demand a series of energy-intensive separation units. However, existing separation mechanisms that discriminate molecular sizes or functional groups are generally unable to achieve molecule-specific adsorption due to insufficiently identified molecular information. We reveal the complementary adsorption mechanism that discriminates molecules through surface electrostatic potential and molecular shape, covering more comprehensive physical and chemical molecular properties, and realizing precise molecular recognition. The constructed novel porous material ZU-501, which exhibits electrostatic potential and shape complementarity toward ethylene, first realizes ethylene-specific adsorption from typical ethylene mixtures, including C1–C4 paraffins and olefins, and carbon dioxide. The practical use potential of ZU-501 for one-step ethylene recovery from a refinery dry gas is validated by scale-up breakthrough experiments and pressure swing adsorption modeling. This work paves an important avenue for the efficient utilization of low-concentration ethylene resources from diverse scenarios.

Achieving stable and efficient alkaline water electrolysis (AWE) under fluctuating renewable energy inputs is essential for large-scale green hydrogen production. However, frequent shutdown-induced reverse current (RC) effects pose significant challenges to electrode durability. Here, we introduce a gradient interlayer engineering strategy to develop robust AWE electrodes that intrinsically resist both electrochemical reconstruction and mechanical fatigue. By constructing a dense interlayer with Ni(112̅)/Ni3S2(1̅20) heterointerfaces, the electrode demonstrates high catalytic activity (1.79 V @1000 mA cm–2─meeting the U.S. DOE 2026 target), excellent operational stability (>1500 h at 1000 mA cm–2 in 30 wt % KOH at 80 °C), and exceptional RC resistance for 3600 accelerated startup/shutdown cycles. Mechanistic studies through cross-sectional characterizations and theoretical calculations reveal that the seamless interlayer at the catalyst–substrate interface enhances interfacial adhesion, mitigates lattice mismatch, and facilitates charge redistribution, ensuring robust stability and integrity even under operational strains and potential reversals. This work establishes interface crystallography as a design paradigm for durable electrodes, potentially overcoming the stability–activity dilemma toward industrially relevant electrolyzers coupled with fluctuating renewable energy sources.

Multi-Color Near-Infrared Object Recognition

Jiahong Wang and co-workers synthesized a vanadium carbide/oxide heterostructure via topochemical conversion, combines the NIR responsivity of V2C with the vacancy-driven volatile resistance switching of V2O5−x. The resulting memristor exhibits a linear correlation with light power and wavelength modulation, allowing for robust multi-color object detection in complex scenarios. More details can be found in the Research Article (DOI: 10.1002/adma.202512238).

Protonic Ceramic Electrochemical Cells

In their Research Article (10.1002/adfm.202513396), Fanglin Chen, Dong Ding, and co-workers present a symmetry-engineered double-sided electrolyte design that enables large-area, curvature-free protonic ceramic electrochemical cells (PCECs). By balancing shrinkage dynamics on both sides of the cell, this strategy effectively suppresses thermally induced warping and delivers ultra-flat, stack-ready devices. Such dimensionally stable PCECs provide a robust platform for efficient stack integration, opening new avenues for scalable hydrogen production and advanced chemical conversion technologies at intermediate temperatures.
