A Smart Access to the Dinitramide Anion - The Use of Dinitraminic Acid for the Preparation of Nitrogen-Rich Energetic Copper(II) Complexes. [PDF]
Chemistry, 2021 The dinitramide anion was made accessible for complexation through the use of dinitraminic acid and basic copper(II) carbonate. The in situ prepared copper dinitramide was complexed by 13 different highly endothermic tri‐ and tetrazole ligands. By the choice of ligand, complexes were obtained that possess thermal stability exceeding 200 degrees Celsius,

Decreasing the hygroscopicity of ammonium dinitramide (ADN) through cocrystallization
Energetic Materials Frontiers, 2022 To decrease the hygroscopicity of ADN—a energetic oxidizer, this study developed a new cocrystal composed of ADN and 18C6 (18-crown-6) at a 1:1 M ratio through cocrystallization using the solvent evaporation method.

Implementing life cycle sustainability assessment for improved space mission design
Integrated Environmental Assessment and Management, Volume 19, Issue 4, Page 1002-1022, July 2023., 2023 Abstract Within the space sector, the application of Environmental Life Cycle Assessment (E‐LCA) is beginning to emerge as a credible and compelling method for scientifically quantifying environmental impacts of space missions. However, E‐LCA does not fully align with the concept of triple‐bottom‐line sustainability, while the combination of all three ...

Progress in Predicting Ionic Cocrystal Formation: The Case of Ammonium Nitrate
Chemistry – A European Journal, Volume 29, Issue 27, May 11, 2023., 2023 Cocrystal design strategies are rapidly evolving to enhance predictive capabilities and improve the efficiency of coformer screening. However, many of the molecular descriptors associated with successful cocrystallization are ambiguous for salts, complicating coformer selection when designing ionic cocrystals.

Combustion Wave Structure of the Ammonium Dinitramide‐Based Ionic Liquid Propellant
Propellants, Explosives, Pyrotechnics, Volume 48, Issue 2, February 2023., 2023 Abstract The ammonium dinitramide‐based ionic liquid propellant (ADN‐based ILP), which is a mixture of ADN, monomethylamine nitrate (MMAN), and urea, is a low toxic monopropellant with a higher performance than that of hydrazine. To clarify the combustion wave structure of ADN‐based ILP, which has low volatility, we focused on the relationship between ...

ADN Solid Propellants with High Burning Rates as Booster Material for Hypersonic Applications
Propellants, Explosives, Pyrotechnics, Volume 47, Issue 7, July 2022., 2022 Abstract RAM‐ and SCRAM‐Jet engines can not generate static thrust and only work at high speeds. This starting velocity of the motor v0 is usually generated by carrier rockets or boosters, which mostly use solid propellants based on ammonium perchlorate (AP) and hydroxyl‐terminated polybutadiene (HTPB).
