Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Omni‐Directional Assembly of 2D Single‐Crystalline Metal Nanosheets
A versatile assembly method is developed to uniformly assemble 2D single‐crystal copper nanosheets (Cu NS) onto substrates with complex shapes via ultrasonication process. This technique leverages cavitation effects to deposit monolayer Cu NS films with minimal overlap.

The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...

Measurements of interactions between acoustic fields and nonuniform mean flow [PDF]
Two problems crucial to the stability of longitudinal acoustic waves in solid rocket motors are examined experimentally. The first is the dissipation of energy associated with an average flow inward at the lateral boundary.

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...
