Recovery of aluminum from composite propellants [PDF]

open access: yes, 1980
Aluminum was recovered from solid rocket propellant containing a small amount of oxidizer by depolymerizing and dissolving propellant binders (containing functional or hydrolyzable groups in a solution of sodium methoxide) in an alcohol solvent ...

Elucidation of the dynamics for hot-spot initiation at nonuniform interfaces of highly shocked materials [PDF]

open access: yes, 2011
The fundamental processes in shock-induced instabilities of materials remain obscure, particularly for detonation of energetic materials. We simulated these processes at the atomic scale on a realistic model of a polymer-bonded explosive (3,695,375 atoms/

Synthesis and Characterization of Methacrylamide‐Based Block Random Copolymers via Amine Functionalization of Polystyrene‐Block‐Poly(Pentafluorophenyl Methacrylate) Toward Enhanced Amenability to Manufacturing Criteria in Nanolithography

open access: yesMacromolecular Chemistry and Physics, Volume 226, Issue 23, December 5, 2025.
Polystyrene‐block‐poly(pentafluorophenyl methacrylate) (PS‐b‐PPFMA) is functionalized with primary amines to develop A‐block‐(B‐random‐C) block copolymers (BCPs). These BCPs exhibit high thermal stability and circumvent sources of undesired side reactions upon heating on account of its methacrylamide functionality.

Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).

Trifluoromethylation of carbonyl groups in aromatic poly(ether ketone)s: formation of strongly polar yet surface-hydrophobic poly(arylenenecarbinol)s [PDF]

open access: yes, 2018
Fluoride-catalyzed reactions of trimethyl(trifluoromethyl)silane with a range of aromatic poly(ether ketone)s, both amorphous and semi-crystalline, proceed quantitatively in THF to yield soluble, amorphous polymers in which the carbon-silicon bond of ...

Thermo‐Mechanical Evaluation of Novel Composite Propellant Formulations Based on Styrene‐Ethylene/Butylene‐Styrene Block Copolymer

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 117-126, December 2025.
ABSTRACT Two novel composite propellant formulations have previously been produced from a binder consisting of the thermoplastic elastomer styrene‐ethylene/butylene‐styrene (SEBS) and a solid filler, either ammonium perchlorate (AP) or 1,3,5‐trinitro‐1,3,5‐triazinane (RDX).
