Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

InfoMat, Volume 8, Issue 10, October 2026.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

Stoichiometric and Fractionation‐Based Assessment for Substitution and Heterogeneity in Sodium Carboxymethylcellulose Produced by Solvent‐Free Reactive Extrusion

Macromolecular Materials and Engineering, Volume 311, Issue 10, October 2026.
Technical sodium carboxymethylcellulose (NaCMC) was synthesized by solvent‐free reactive extrusion, and its substitution level and heterogeneity were assessed through innovative, complementary approaches. Stoichiometric data reconciliation enabled indirect degree of substitution (DS) quantification, while centrifugation fractionation resolved distinct ...
