Advanced Science, EarlyView.Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

Structural Colors from Modulated Topological Defects in Molecular Smectic Liquid Crystals
Advanced Science, EarlyView.Rather than using dyes and pigments, nature produces the colors of some butterflies and beetles through optical interference phenomena. This study describes an original biomimetic strategy exploiting the spontaneous formation of modulated linear defects in thin films of 8CB, a common molecular liquid crystal.

Advanced Science, EarlyView.The concept of high‐dimensional EM modulation using the STMA for physical layer secure communication is illustrated in figure. The STMA consists of a series of programmable unit cells, with 1‐bit reconfigurable phase states (0/π). The STMA is excited by a monochromatic continuous wave (CW) at frequency fc and controlled by a field‐programmable gate ...

Efficient Polarization‐Entangled Photon‐Pair Generation by a Fiber‐In‐Line van der Waals Material
Advanced Science, EarlyView.Telecom‐wavelength polarization‐entangled photon pairs are generated in a van der Waals‐material‐integrated all‐fiber device via spontaneous parametric down‐conversion. The demonstrated fiberized quantum light source bridges emerging 2D nonlinear materials and practical quantum photonic systems, opening new opportunities for scalable fiber‐based ...

Advanced Science, EarlyView.Inspired by the intricate microstructure of cicada wings, researchers developed a novel in situ skeleton‐graphene membrane architecture within lightweight foams. This bioinspired design dramatically enhances multifunctional performance: vibration attenuation time decreases by ∼83.3%, damping capacity increases by ∼179.3%, and compressive modulus rises ...
