Unsupervised Particle Image Velocimetry Network Based on Improved LiteFlowNet3 with Embedded Cross-correlation and H-RAMi Attention Mechanism [PDF]

Journal of Applied Fluid Mechanics
Unsupervised particle image velocimetry (PIV) methods eliminate the need for extensive labeled datasets, yet their performance in complex flow regions, such as those with particle occlusion or out-of-boundary motion, remains limited.

Science‐Towards‐Technology Breakthrough in CO2 Electroreduction: Multiphysics, Multiscale, and Artificial Intelligence Insights

Advanced Materials, EarlyView.
Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion

Advanced Science, EarlyView.
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.

X-Ray imaging method for in-situ study of particle-laden flows

e-Journal of Nondestructive Testing
 The accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However,
