Preparation of HMX@NPBAs microparticles by coating process with improved mechanical properties, thermal stability, and safety performance
Bibliographic record
Abstract
Polymer-bonded explosives (PBXs) played a critical role in lethality and destruction as a vital military explosive in the world. Unfortunately, the current PBXs exhibit poor properties in safety performance and reliability for the weak interfacial surface, which cannot meet requirements of the high security and high reliability of weapons and ammunition in the harsh environment of modern battlefields. Herein, the neutral polymeric bonding agents (NPBAs) were successfully coated on the surface of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX) and proved to enhance the mechanical performance and reliability of PBXs. The scanning electron microscopy images indicated a slight aggregation of NPBAs coated in the HMX surface, the XRD spectra of HMX@NPBAs had an analogous spectrum of HMX, and the X-ray photoelectron spectroscopy spectrum confirmed that the NPBAs played a role on the surface of HMX by coating. Furthermore, the HMX coated with NPBAs had more excellent safety performance, thermal stability, and mechanical properties. The strategy is helpful to strengthen the interaction between HMX and binder matrix, which provides a brilliant idea in modifying for the weak interfacial surface of energetic crystals.

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.
