Using interferometric imaging, we observe a different behavior for a levitated hydrogel sphere. Curvature inversion appears briefly after deposition, but the continuous vaporization process removes this feature, leading first to an oscillatory regime and eventually to a steady state without curvature inversion. We demonstrate the essential role of vaporization in shaping the hydrogel underbelly, where direct mass loss has a stronger influence than the balance between vapor pressure and elastic forces.","lang":"eng"}],"publication_identifier":{"issn":["2663-337X"]},"doi":"10.15479/AT-ISTA-23005","citation":{"ama":"Diaz Melian VL.
