New concept for the design of zero-hydrogen energetic materials with high energy and low sensitivity: achieving a good balance among parent compounds, nitro groups, and <i>N</i>-oxides
Bibliographic record
Abstract
A new powerful zero-hydrogen energetic compound DNDOBTT (2,7-dinitro-4N,9N-dioxide-bis[1,2,4]-triazolo)[1,5-b:1′,5′e][1,2,4,5] tetrazine) was produced by a new design concept of achieving a balance among the parent compound, nitro groups, and N-oxides. Its structure and properties was studied by the density functional theory. The breaking of N–N bond in the tetrazine ring is an initial decomposition step of DNDOBTT, and the energy barrier was predicted to be 175 kJ·mol −1 . DNDOBTT has comparable detonation performance with some CHNO energetic compounds, including the most powerful ONC (octanitrocubane), whereas its sensitivity and thermal stability are obviously lower and better than those of ONC, respectively, indicating that DNDOBTT has both the high energy and reduced sensitivity and may be a valuable candidate for experiments. Therefore, a new novel energetic material DNDOBTT with good overall performance has been obtained successfully by the new design concept, and it may be applied to design and develop other novel improved zero-hydrogen energetic materials.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
