Mesostructured Fe Oxide Synthesized by Ligand-Assisted Templating with a Chelating Triol Surfactant
Bibliographic record
Abstract
The synthesis and properties of sulfate- and phosphate-free mesostructured iron oxide prepared using a chelating triol surfactant are reported. Materials synthesized using metal−surfactant ratios of 1:1, 2:1, 3:1, and 4:1 all showed a broad single reflection in the XRD at low angle corresponding to a wormhole mesostructure, as well as small higher angle peaks consistent with the presence of a small amount of maghemite and hemitite. TEM images confirmed the wormhole structure of the mesophase, while also revealing rodlike crystals corresponding to one or both of the two known phases of iron oxide observed in the XRD. Attempts to remove the surfactant by washing or chemical treatment were unsuccessful. Calcination led to a complete collapse of the structure and crystallization of the mesophase into maghemite. Magnetic studies provided evidence for the formation of superparamagnetic iron oxide particles within the walls of the mesostructure in addition to a small magnetic contribution arising from the presence of larger maghemite crystallites, while the calcined materials behaved more like a soft ferromagnet.

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.
