Preparation of Cyclotrimethylenetrinitramine‐Copper Oxide Core‐Shell Particles and Their Thermal Decomposition Kinetics
Bibliographic record
Abstract
Abstract The effect of interfacial contact conditions between cyclotrimethylenetrinitramine (RDX) and copper oxide (CuO) on the thermal decomposition kinetics of RDX was investigated in this study. CuO was deposited onto the surface of superfine RDX particles to form RDX@CuO core‐shell structure through RF magnetron sputtering technology. The thermal decomposition characteristics of RDX, RDX@CuO and RDX‐CuO ultrasonic mixture were studied through thermo‐gravimetric method. Kissinger and Kissinger‐Akahira‐Sunose methods were used to obtain kinetic parameters of thermal decomposition processes. It was found that the temperature corresponding to maximum weight loss rate decreased in the order of RDX>RDX‐CuO>RDX@CuO. However, the apparent activation energy of RDX decomposition did not show apparent difference for the two kinds of CuO‐containing samples. The results indicate that the interfacial contact conditions between RDX and CuO have an effect on the thermal stability of RDX but do not alter the thermal decomposition paths of RDX.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
