Chiral 3D Perovskite Single Crystals Realized by Lattice Expansion

open access: yesAdvanced Science, EarlyView.
A novel chiral 3D perovskite [(R/S)‐3APr]2Pb4I12·2H2O single crystal is reported. This structure can accommodate large chiral diammonium cations while maintaining 3D skeletons by modulating the connectivity of [M2X10] dimers. The chiral 3D perovskite photodetectors exhibit notable circularly polarized light (CPL) detection performance.

Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts

open access: yesAdvanced Science, EarlyView.
An organogel interface with a large energy barrier for ice nucleation is proposed to enable a quasi‐homogeneous supercooling preservation for organs. This method does not rely on cryoprotectant agents or machine perfusion and can double the ex vivo storage time of mouse hearts.

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.

Helical Photonic Metamaterials for Encrypted Chiral Holograms

open access: yesAdvanced Science, EarlyView.
This article explores the untapped potential of 3D‐printed helical structures as chiral metamaterials and metaholograms by uncovering how specific geometric parameters govern their chiroptical behavior. Combining terahertz experiments and simulations, it reveals how tunable, stretchable helices enable broadband ellipticity and encrypted QR codes ...
