Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, Volume 38, Issue 59, 22 October 2026.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3

Advanced Materials, Volume 38, Issue 57, 13 October 2026.
Through precise epitaxial engineering, the cubic and paraelectric KTaO3${\rm KTaO}_3$ is transformed into a robust ferroelectric. By leveraging lattice‐mismatched substrates to apply controlled epitaxial strain, a stable ferroelectric ground‐state is achieved with a transition temperature as high as 475 K, establishing KTaO3${\rm KTaO}_3$ as a highly ...

Freeform Light Routing in Nearly‐Hyperuniform Slabs: Toward a General‐Purpose Design Platform for Integrated Photonics

Advanced Optical Materials, Volume 14, Issue 37, 9 October 2026.
Nearly hyperuniform disordered photonic slabs guide light along prescribed freeform pathways without relying on lattice symmetry. A pathway‐first design embeds curved channels within a photonic bandgap hyperuniform network, maintaining high transmission through freeform bends.

Donor‐Strength‐Driven Evolution From Charge‐Transfer to Polymethine Excited States in CurcBF2 Derivatives

Advanced Optical Materials, Volume 14, Issue 39, 23 October 2026.
Donor strength governs the excited‐state character and TADF behavior of donor‐acceptor‐donor borondifluoride curcuminoid derivatives. Increasing donor strength drives a transition from charge‐transfer TADF to a zwitterionic polymethine structure with predominantly local excited‐state emission and suppressed TADF.

Linear and Nonlinear Optical Tuning With Sb2S3‐Based Metasurfaces

Advanced Optical Materials, Volume 14, Issue 40, 27 October 2026.
Sb2S3${\rm Sb}_2{\rm S}_3$ resonant metasurfaces provide large, reconfigurable optical modulation and tunable enhanced nonlinear emission across telecommunication wavelengths. Monolithic structures achieve 92% transmission modulation and 150 nm resonance tuning, while hybridization with silicon enables strong modulation at nearly half the switching ...

Structural Colors from Modulated Topological Defects in Molecular Smectic Liquid Crystals

Advanced Science, Volume 13, Issue 58, 19 October 2026.
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.
