Magneto-mechanical properties of micron Fe_3O_4/polyvinyl alcohol magnetic hydrogels prepared by freezing-thawing method
Bibliographic record
Abstract
Magnetic hydrogels based on PVA and magnetite Fe3O4 micron-particles are prepared by the repeated freezing-thawing(F-T) method.Elongation behaviors,magnetic field threshold and other magnetic properties of ferrogels with different Fe3O4 concentrations and freezing-thawing cycle times are systematically investigated,and scanning electron microscopy(SEM) and X-ray diffraction(XRD) technique are used to study the cross-sectional micro-morphology and crystal structures of the Fe3O4/PVA magnetic hydrogels,respectively.The results show that elongation behaviors and magneto-mechanical properties of the Fe3O4/PVA hydrogels are dependent on the Fe3O4 concentrations and freezing-thawing cycles.Magnetic particles are found to be dispersed in hydrogels homogeneously.The degree of crystallization of PVA hydrogels can be improved by increasing the number of freezing-thawing cycles.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
