Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1365-1374, August 2026.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Strength criterion of composite solid propellants under dynamic loading

Defence Technology, 2018
Based on the dynamic loading (1-100 s−1) experiments under different temperatures (223–298 K) and stress states, uniaxial and biaxial strength criterion of a Hydroxyl-terminated polybutadiene (HTPB) based composite solid propellant were further ...

Controllable Energy Release of Boron@Tannic Acid@Ammonium Perchlorate Energetic Microunits Governed by Cu Single Atoms

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Controllable energy release in solid propellants has always been a challenging technology, and extensive efforts have been devoted to the synthesis and application of catalysts to achieve its controllable release. In this study, tannic acid (TA) and its complexes (TA‐Cu) were introduced into boron@ammonium perchlorate (B@AP) composites using ...

Hydroxyl‐Terminated Polybutadiene‐Based Molding Powders as an Alternative Route for Manufacturing Pressed Polymer‐Bonded Explosives

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 6, Page 955-965, June 2026.
This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.
