Abstract

fetched live from OpenAlex

Soft X-ray spectromicroscopy is emerging as a powerful method for the chemical and structural analysis of nanostructured organic materials. X-ray spectromicroscopy combines the chemical and structural sensitivity of Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy with the high spatial resolution of X-ray microscopy. Linear Dichroism (LD), the anisotropic absorption of linearly polarised radiation by an oriented molecule, is observed in NEXAFS spectra. LD-NEXAFS offers excellent sensitivity to molecular orientation, and can be used to characterise molecular order in materials at high spatial resolution. Technical developments in X-ray microscopy and synchrotron undulator sources have enhanced X-ray Linear Dichroism Microscopy (XLDM) studies of organic materials. This paper will review the state of XLDM for studies of oriented organic materials, its relationship to other techniques, and the prospects for the study of nanoscale organic materials with new spectromicroscopy facilities, such as those at the Canadian Light Source.

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.
