Abstract
The abundance of non-linear phenomena in physical chemistry was so large that in 1926, a review article with the telling title “The Problem of Physico-Chemical Periodicity” was published. This chapter illustrates the breadth of non-linear dynamics for just one surface reaction, carbon monoxide (CO) oxidation on various types of platinum (Pt) surfaces by using examples mostly from authors' own work based on the observation of self-sustained patterns and the external forcing of patterns. Many catalytic reactions, both solid/gas and liquid/solid have demonstrated novel nonlinear phenomena, in particular in the field of electrochemistry. The chapter dwells on the pattern formation aspects of nonlinear chemical systems. After a brief introduction to the experimental methods utilized for investigating surface reactions, the chapter illustrates the depth of the current understanding and the many forms to control patterns during the CO oxidation on Pt surfaces.

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
