Characterisation and thrust measurements from electrolytic decomposition of Ammonium Dinitramide (ADN) based liquid monopropellant FLP-103 in MEMS thrusters [PDF]
, 2017 Although Ammonium Dinitramide (ADN) has been targeted as a potential green monopropellant in future space vehicles, its application potential in Micro-electrical-Mechanical System (MEMS) thrusters or microthrusters have seldom reported in open literature.

An Optimized & Scaled‐Up Synthetic Procedure for Trinitroethyl Formate TNEF
Propellants, Explosives, Pyrotechnics, Volume 46, Issue 6, Page 895-898, June 2021., 2021 Abstract Previous reports showed, that tris(2,2,2‐trinitroethoxy)methane, also known as tris(2,2,2‐trinitroethyl) orthoformate or trinitroethyl formate (TNEF), exhibits a very high potential for application due to its excellent energetic properties and compatibility with state of the art binder systems for composite propellants. However, TNEF was never

Propellants, Explosives, Pyrotechnics, Volume 46, Issue 2, Page 233-244, February 2021., 2021 Abstract Ammonium dinitramide (ADN) may serve as a ‘green’ oxidizer for rocket propellants since it provides chlorine free and minimum signature exhaust gases. However, stability issues and an erratic decomposition behaviour limit its non‐questionable general usability. Nitric acid (HNO3) is a decomposition product of ADN and is known to accelerate the

Thermal Behavior and Micro Structure of TKX‐50
Propellants, Explosives, Pyrotechnics, Volume 46, Issue 2, Page 262-266, February 2021., 2021 Abstract The thermal behaviour of TKX‐50 was reinvestigated in an extended temperature range by means of temperature resolved X‐ray diffraction. TKX‐50, synthesized at the Fraunhofer ICT, was identified using Rietveld‐analysis and reference data from the CCDC.
