Abstract
Liquid metal systems are increasingly important due to their versatility in applications, including catalysis, flexible electronics, and synthesis processes. The ultra-thin native oxide skin that forms at the liquid metal-air interface can influence these applications positively or negatively, depending on whether a dynamic or static interface is required. We hypothesise that a deeper understanding of the oxide layer's behaviour and interaction forces could enable advancements in liquid metal applications. We developed a method to create liquid metal micro-islands—hemi-spherical regions of liquid metal adhered to solid substrates with a fluidic nature and an outer native oxide layer. Using atomic force microscopy (AFM), including surface-normal and lateral force spectroscopy, we investigated the forces between the oxide layer and the underlying liquid metal. Our AFM measurements reveal that the scalar force needed to delaminate the oxide layer from the liquid metal interior is ∼1 µN, with a force per unit area of ∼69 nN/nm². Moreover, this work suggests that the developed protocol for creating liquid metal micro-islands could serve as a platform technology for in-situ analysis of liquid metal systems, facilitating further research in this area.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
