Amine‐AlH3 Adducts as Energetic Materials for a New Generation of Solid Fuels
Chemistry – A European Journal, Volume 31, Issue 40, July 17, 2025.New amine‐AlH₃ adducts offer a more environmentally friendly, high‐energy alternative to conventional rocket propellants, and exhibit ultra‐fast ignition. They can be synthesized by mechanochemical method under hydrogen pressure starting from aluminum metal directly or by wet chemical processes with AlH3.

Moisture And Temperature Ageing On htpb Based Propellants Binder
Macromolecular Symposia, Volume 414, Issue 3, June 2025.Abstract This study reports the impact of temperature, oxygen, and humidity ageing on the mechanical properties of a crosslinked hydroxy‐terminated polybutadiene (HTPB) network. Its mechanical behavior is described using a classical Mooney‐Rivlin model and shows a slight crosslinking reaction possibly due to oxidation of HTPB.
