Abstract

fetched live from OpenAlex

A synthetic protocol was developed to create a unique nitrogen-rich (71.58% N) energetic material, namely, 2,3,5,6-tetra(1 H -tetrazol-5-yl)pyrazine (H 4 TTP). This compound was prepared using a convenient and straightforward method of synthesis and shows useful energetic properties such as detonation velocity ( V C-J = 8655 m s –1 ), detonation pressure ( p C-J = 28.0 GPa), and high temperature of decomposition ( T dec = 260 °C). H 4 TTP was isolated and characterized using mass spectrometry, multinuclear ( 1 H, 13 C) NMR spectroscopy, and vibrational spectroscopy (IR, Raman). The molecular structure was determined via single-crystal X-ray diffraction. High nitrogen content and relative planarity of the molecule, along with the attained properties such as hydrolytic stability, high thermal stability, density, detonation velocity, and its facile synthesis, make H 4 TTP a highly interesting energetic material.

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.
