Abstract

fetched live from OpenAlex

In the present study, pressure waves generated by a metastable intermolecular composite (MIC) have been measured experimentally in an aqueous environment and correlated with flame speed measurements. Underwater experiments were performed in a 1.0 L high-pressure chamber mounted with high-resolution pressure transducers and designed with optical access. Samples consisting of a stoichiometric mixture of aluminium and copper(II)-oxide particles were evaluated. Two types of samples were synthesized; a mixture of micron-sized raw powders, and ball-milled powders with a fine-scale nano-structure. A planetary mill was used to refine reactant powders from micron- to nano-scale dimensions. The dynamics of the pressure wave and high-pressure gas bubble were monitored via pressure histories and high-speed Schlieren visualization. The effect of reactant particle size has been evaluated quantitatively. The dynamics of the pressure wave were correlated with the rate of expansion of the high-pressure gas bubble.

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.
