2D Peptide Crystals
A dodecapeptide and its two mutants self‐organize to form 2D molecular crystals with oblique symmetries on an atomically flat graphite lattice, each exhibiting an exclusive crystallographic chiral relationship, resulting in a coherent bio/nano hybrid soft interface with the potential to serve as a foundation for future bio/nanodevices. More in article number 2400653, Ayhan Yurtsever,...
Sonodynamic therapy (SDT) as a promising non‐invasive anti‐tumor means features the preferable penetration depth, which nevertheless, usually can't work without sonosensitizers. Sonosensitizers produce reactive oxygen species (ROS) in the presence of ultrasound to directly kill tumor cells, and concurrently activate anti‐tumor immunity especially after integration with tumor microenvironment (TME)‐engineered...
Hybrid ion capacitors (HIC) are receiving a lot of attention due to their potential to achieve high energy and power densities, but they remain insufficient. It is imperative to explore outstanding and environmentally benign electrode materials to achieve high‐performing HIC systems. Here, a unique boron carbon nitride (BCN)‐based HIC system that comprises a microporous BCN structure and Fe1−xS nanoparticle...
Passivating the electronic defects of metal halide perovskite is regarded as an effective way to improve the power conversion efficiency (PCE) of perovskite solar cells (PVSCs). Here, a series of dipeptide molecules with abundant ─C═O, ─O─ and ─NH functional groups as defects passivators for perovskite films are employed. These dipeptide molecules are utilized to treat the surface of prototype methyl...
The development of ultraviolet circularly polarized light (UVCPL) sources has the potential to benefit plenty of practical applications but remains a challenge due to limitations in available material systems and a limited understanding of the excited state chirality transfer. Herein, by constructing hybrid structures of the chiral perovskite CsPbBr3 nanoplatelets and organic molecules, excited state...

2D Selectors
In article number 2310158, Yanpeng Liu, Wanlin Guo, and co‐workers devise a 2D graphene/hBN/WSe2 selector that exhibits outstanding bipolar nonlinearity at room‐temperature. Profiting from well‐designed band alignment and proper tunneling barrier, the selector undergoes direct tunneling at low bias, and Fowler‐Nordheim tunneling at high bias. This proof‐of‐concept demonstration opens...
Shape memory hydrogels provide a worldwide scope for functional soft materials. However, most shape memory hydrogels exhibit poor mechanical properties, leading to low actuation strength, which severely limits their applications in smart biomimetic devices.

The evolution of porous membranes has revitalized their potential application in sustainable osmotic‐energy conversion. However, the performance of multiporous membranes deviates significantly from the linear extrapolation of single‐pore membranes, primarily due to the occurrence of ion‐concentration polarization (ICP). This study proposes a robust strategy to overcome this challenge by incorporating...
Adhesive materials have played an essential role in the history of humanity. Natural adhesives composed of low‐molecular‐weight monomers have been overshadowed by modern petroleum‐based glues.
