Manipulating droplets on surfaces: using the electrocapillary effect for control and applications
Bibliographic record
Abstract
The electrocapillary force offers a promising approach to manipulate droplets on surfaces by inducing deformations that create regions of varying surface tension. This abstract explores the hypothesis and provides two examples to illustrate its potential. Droplet manipulation on surfaces encompasses the interplay of surface wettability, external forces, and engineered interfaces. Surface wettability, influenced by interfacial tension and surface energy, governs droplet behavior and can be controlled through surface treatments. The mechanism ternal forces, including electrocapillary forces like electrowetting, electrostatic actuation, and dielectrophoretic, enable precise manipulation of droplets, while other forces like magnetic or acoustic forces can also be employed. In the wrinkled surfaces and slippery surfaces, reduce or increase adhesion facilitate controlled droplet movement. Integrating these aspects allows for the development of diverse applications in the fields where droplet manipulation is essential. The implications and applications of the hypothesis are explored, ranging from microfluidics to surface coatings and biomedical engineering. The conclusion outlines future research directions, identifies challenges, and summarizes the main findings of the paper. It also reflects on the broader significance of the research and suggests approaches to overcome challenges in future studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
