Modular Fabrication of Quantum‐Dot–Plasmonic Metasurfaces for Tailored Optical Modes

Small Structures, Volume 7, Issue 5, May 2026.
Our modular photonic architecture is illustrated using color‐coded building blocks representing colloidal quantum dots, gold nanoparticles, and thin films. This visual metaphor highlights our bottom‐up and top‐down fabrication approach, enabling the creation of tailored optical modes for optoelectronic applications.

Brillouin Scattering Observations of Elastic Behavior Across the Post‐Stishovite Transition Under Deviatoric Stress in Polycrystalline Al‐Bearing Stishovite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stishovite (SiO2), a key phase in subducted mid‐ocean ridge basalt (MORB), undergoes a ferroelastic transition to a CaCl2‐type structure, potentially explaining localized shear wave velocity (VS) anomalies in the shallow to mid‐lower mantle. However, the phase boundary determining this transition remains debated.

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).

Strain Development During Cure of Partially Pre‐Cured Thermosetting Composites Measured With Distributed Fiber Optic Sensors

Polymer Composites, Volume 47, Issue 8, Page 7155-7169, 20 April 2026.
Schematic representation of the beneficial effect of ply pre‐curing on temperature overshoot, internal strain and warpage during cure of thin and thick thermosetting composites. ABSTRACT Detection of manufacturing‐induced defects in thermosetting composites is crucial to guarantee part quality, safety, and improve manufacturing efficiency.
