Mechanism and Kinetics for Ammonium Dinitramide (ADN) Sublimation: A First-Principles Study

The Journal of Physical Chemistry A, 2012
The mechanism for sublimation of NH(4)N(NO(2))(2) (ADN) has been investigated quantum-mechanically with generalized gradient approximation plane-wave density functional theory calculations; the solid surface is represented by a slab model and the periodic boundary conditions are applied.

Melamine-Modified Gold Nanoparticle–Based Direct Colorimetric Sensing of the Solid Rocket Propellant Ammonium Dinitramide (ADN) at Sub-Picomolar Levels

Analytical Letters
Ammonium dinitramide (ADN) is an environmentally friendly solid rocket propellant. In this work, a spectroscopic sensor based on gold nanoparticles (AuNPs) was developed to directly determine ADN at sub-picomolar level, involving the aggregation of ...

Study on the State Change of Ir/Al₂O₃ Catalyst by Decomposition of Ammonium Dinitramide (ADN) Based Low-Toxicity Monopropellant.

Journal of Nanoscience and Nanotechnology, 2020
The change of the Ir/Al₂O₃ catalyst before and after the reaction with ADN based low-toxicity monopropellant was confirmed. The catalyst were recovered after decomposition reaction with propellant in a monopropellant thruster at 350 °C preheating ...

Ammonium Dinitramide (ADN) Decomposition as Green Propellant

Thermal decomposition of eco-friendly propellants such us ammonium dinitramide (ADN) aims to replace hydrazine in satellite systems. ADN, with formula [NH4]+[N(NO2)2]−, is a promising high-performance rocket propellant. It decomposes cleanly, producing gases such as NH3, H2O, NO, N2O, NO2, HONO, and HNO3, making it an attractive alternative to ammonium

Modeling the Reactions Between Ammonia and Dinitrogen Pentoxide to Synthesize Ammonium Dinitramide (ADN)

Chemical Engineering & Technology, 2002
Only three references about the reactions of ammonia (NH 3 ) with dinitrogen pentoxide (N 2 O 5 ) have been published in the course of the last 150 years. None of them describes the reactions referring to the products in dependence on the reaction conditions.

Study of the thermal initiation of ammonium dinitramide (ADN) crystals and prills

Journal of Energetic Materials, 2000
Abstract The thermal initiation by electron beam heating (and calibrated hot stage), of single crystals and prills of ADN, has been filmed / recorded in an Environmental Scanning Electron Microscope, from the formation of microscopic “reaction sites” (0.01 μm in diameter) to full crystal consumption.

Degradation of ammonium dinitramide (ADN) in digested sewage sludge under strict anaerobic conditions

Toxicological & Environmental Chemistry, 2000
The biodegradation of one popular nitramine energetics, ammonium dinitramide (ADN) by mixture of denitrifying bacterial species was investigated. ADN was observed to be effectively mineralized in the anaerobic mixed culture. The initial ADN concentration of 250 mg/L was reduced to non‐detectable levels (> 99% removal efficiency) in 5 days of incubation

Analysis of anionic impurities in ammonium dinitramide (ADN), Part I: Ion chromatographic analysis

Journal of Energetic Materials, 1996
Abstract A method has been developed to analyze ammonium dinitrimide, a new energetic material, as well as other anionic impurities in it. This method employs ion chromatography with UV detection. Analysis of ADN samples could be done in under 20 minutes employing this method. Analysis of pure samples as well as aged samples was accomplished.
