Tuesday publication post! 📖 In this newest study, the #FusionAX system was used to investigate phase-change behavior in a liquid metal colloidal system. By examining dissolution and recrystallisation in a Ga–Cu system, the group at @RMIT with Edwin Mayes reveal how solute transport and crystallisation occur inside liquid metals, an area that remains underexplored despite its relevance to catalysis, phase change materials, and additive manufacturing.
Key highlights:
🔥 Direct observation of Ga2Cu crystals dissolving layer-by-layer into liquid gallium during heating
💠 Complete dissolution followed by rapid recrystallisation under supercooled liquid metal conditions
🔬 In-situ TEM enabled nanoscale tracking of crystallisation and dissolution dynamics in real time
📈 A simplified diffusion model, supported by computational analysis, provides insight into solute flux and mass transport in liquid metals
This work highlights how nanoscale in-situ microscopy can uncover fundamental processes governing liquid metal systems. This knowledge is crucial for applications in catalysis, synthesis, phase change materials, and energy storage.
