Updated Insights Into the Mechanism of Salt‐Induced Aggregation‐Based Single‐Molecule Surface‐Enhanced Raman Spectroscopy

open access: yesAdvanced Science, EarlyView.
A salt‐gradient model is proposed to investigate the physical nature and update insights into the single molecule surface‐enhanced Raman spectroscopy (SM‐SERS). The release of Ag+ ions from the Ag NPs and the final formation of precipitate of AgCl with Cl‐ on the surface of the aggregated Ag NPs plays as the active and packaging shell to improve the SM‐

Surface‐Engineered Cenospheres Encapsulating Phase Change Materials for Functional Cementitious Composites

open access: yesAdvanced Science, EarlyView.
The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using

Achieving High Damping Capacity in Oxygen‐Enhanced BCC Zr‐Hf‐Ti‐Nb Multi‐Principal‐Element Alloys with Low Young's Modulus

open access: yesAdvanced Science, EarlyView.
A series of oxygen‐enhanced Zr‐Hf‐Ti‐Nb MPEAs with high strength and outstanding damping capacity are developed through tailoring the BCC structural stability by an elaborate composition regulation. Strengthening mechanism for high strength and damping mechanism related to various Snoek‐type relaxations reveals that the existence of multiple separate O‐

Lattice‐Distortion‐Driven Reduced Lattice Thermal Conductivity in High‐Entropy Ceramics

open access: yesAdvanced Science, EarlyView.
Long‐believed potential mechanisms of lattice distortion and mass fluctuation for the reduced lattice thermal conductivity are explored by designing two groups of high‐entropy diborides based on machine‐learning‐potential‐based molecular dynamics simulations.

Multi‐Dimensional Multiplexed Metasurface for Multifunctional Near‐Field Modulation by Physics‐Driven Intelligent Design

open access: yesAdvanced Science, EarlyView.
The expansive design space of advanced metasurfaces, particularly those with multiple degrees of freedom (MDOF), renders traditional design methods less effective. A physics‐driven intelligent design is proposed for MDOF metasurfaces, which integrates physical knowledge into neural networks, enhancing interpretability and computational efficiency. This
