Abstract
Third-generation synchrotron light source technology has greatly improved the capabilities for materials analysis using tunable X-rays. Two such capabilities developed recently are reported herein - inverse partial fluorescence yield (IPFY) XANES (X-ray absorption near edge structure) and 2D XANES - XEOL (X-ray excited optical luminescence) in both the energy and time domain. These techniques take advantage of recent advances in soft X-ray solid state detector, optical spectrometer with a CCD detector and optical streak camera on a soft X-ray beamline as well as new data acquisition schemes. The studies of LiFePO4 materials for Li ion battery and solid solutions of GaN-ZnO nanostructures for water splitting are used to illustrate these capabilities. The prospects of these and related synchrotron photon-in photon-out techniques are also noted.

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
