Do We Really Know Why Carbon Nanotubes Grow?

Small, EarlyView.
The CNT growth mechanism is still debated. We propose a heterogeneous (2D) classical nucleation framework comparing pathways for graphenic patches, caps, and full CNTs. Despite its simplicity, it rationalizes key trends, including the correlation between catalyst particle size and CNT diameter.

Experimental and ReaxFF‐MD Insights Into the Suppression Mechanism of Melamine Cyanurate on Aluminum Dust Explosion

Safety Science and Technology, EarlyView.
This study experimentally determined that the critical suppression concentration of MCA for 30 μm aluminum dust is 750–800 g/m3. An atomic‐scale Al/suppressants combustion suppression model was established, revealing the microscopic mechanism that hinders oxidation and combustion of cAl atoms, and elucidating the synergistic physical–chemical ...
