Record Index–Bandgap Trade‐Off: CdPS3 as a High‐Index van der Waals Platform for Ultraviolet–Visible Nanophotonics

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
The fundamental index–bandgap trade‐off strictly limits materials for short‐wavelength nanophotonics. The van der Waals crystal CdPS3 emerges as a compelling alternative platform challenging this paradigm. Combining an exceptionally high refractive index approaching 3 with a broad mid‐infrared‐to‐ultraviolet transparency window, CdPS3 unlocks new ...

Simultaneous Type‐0 and Type‐I Optical Parametric Oscillation in Submicron Poled Thin‐Film Lithium Niobate

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Backward optical parametric oscillation is realized in a submicron‐poled thin‐film lithium niobate microring. By engineering the quasi‐phase‐matching condition, both type‐0 and type‐I degenerate oscillation emerge in the same device and are selectively accessed through temperature tuning, providing a versatile on‐chip platform for polarization‐diverse ...

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Synchronizing the Osteochondral Regeneration Process through Spatial Patterning of Stable and Hypertrophic Cartilage Organoids

Advanced Materials, Volume 38, Issue 33, 12 June 2026.
Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.
