Inside Back Cover: Activation of Ultrathin Films of Hematite for Photoelectrochemical Water Splitting via H<sub>2</sub> Treatment (ChemSusChem 9/2015)
Bibliographic record
Abstract
The Inside Back cover picture shows ultrathin films of α-Fe2O3 before and after treatment in 5 % H2 in Ar at 450 °C. The hydrogen treatment creates oxygen vacancies in the iron oxide lattice, resulting in a non-stoichiometric hematite phase that is active for photoelectrochemical water oxidation. Electrochemical impedance spectroscopy reveals the buildup of a surface state capacitance that is only present for the hydrogen treated films when under illumination, at the point of photocurrent onset. A concomitant decrease in charge trapping resistance suggests that this is due to a build-up of photogenerated holes at the surface of the H2-treated films, which allows the water oxidation reaction to proceed. More details can be found in the Full Paper by Moir et al. on page 1557 (DOI: 10.1002/cssc.201402945).

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; both teacher heads agree on what is shown here.
