3D Acoustic Imaging Hitting the Diffraction Limit via Fully Parameter‐Optimized Meta‐Lens and Frequency‐Domain Reconstruction

open access: yesAdvanced Materials, EarlyView.
This article employs a binary genetic algorithm to design an ultra‐fine ultrasonic meta‐lens, achieving lateral super‐resolution imaging in the far field (>20λ₀). Building on this, longitudinal resolution is effectively restored through frequency domain reconstruction.

Recent Advances in Reactive Microdroplets for Clean Water and Energy

open access: yesAdvanced Materials, EarlyView.
Reactive microdroplets enable precise and sustainable chemistry at small scales. This review explores their role as confined reactors and dynamic interfaces for synthesizing functional materials, fuels, and microdevices. It offers a critical perspective on how droplet‐based platforms can drive next‐generation technologies in clean energy, environmental

Sound, Force and Light Induced Emissions from Er3+‐Mn2+ Doped ZnS/CaZnOS Heterostructure for Remote Temperature Monitoring via Photo‐ and Mechanoluminescence

open access: yesAdvanced Materials, EarlyView.
Er3⁺/Mn2⁺ co‐doped ZnS/CaZnOS heterostructures are developed for remote temperature and force/sound sensing. The material exhibits UV/NIR photoluminescence, with energy transfer influencing color. Mechanoluminescence intensity is measured against applied power. Temperature‐dependent photoluminescence enabled luminescence thermometry.
