Rheological Characterization of Low and High‐Solids‐Loaded Suspensions Using Capillary Rheometry

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 144-156, January 2026.
ABSTRACT Controlled extrusion of viscous liquids with suspended solids depends critically on rheology. The rheology of a binder (9:1 mass ratio of cellulose acetate butyrate (CAB) to triacetin with a 55 wt.% diethyl ketone balance) loaded with dilute (0–15 wt.%) and concentrated (≥50 wt.%) granulated sugar loadings from three particle size ...

Chemorheological Kinetic Modeling of Uncatalyzed Hydroxyl‐Terminated Polybutadiene and Isophorone Diisocyanate

Macromolecular Materials and Engineering
Catalysts are often employed to enable nonisothermal reaction kinetic studies when tracking cure progression of polyurethane reactions. However, when quickly reacting, catalyzed materials are prepared through mixing followed by the addition of fillers or

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

, 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

Macromolecular 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

Propellants, 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]).
