Abstract

fetched live from OpenAlex

Silica gel films prepared from mixtures of triethoxysilane (TH) and Fe nitrate Fe(NO)3·9H2O were irradiated with various fluences of 3 MeV Au ions. Silicon 2p x-ray absorption (XAS) and L2,3 x-ray emission spectra of irradiated TH:Fe films are found to be very similar to those of SiO2, providing direct evidence of the formation of a glassy matrix. Fe L2,3 XAS shows the reduction of Fe3+ ions at low fluence, initially attributed to the formation of Fe metallic nanoparticles. Mössbauer spectra of films irradiated with higher ion fluences are well fitted by a singlet associated with superparamagnetic Fe particles and a doublet associated with Fe2+ ions in Fe–Si–O complexes.

Full frame distilled prediction

Teacher imitation

Not 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.
