Advancing nitrocellulose thermal stability through the incorporation of ion-exchanged ZSM-5 zeolite for enhanced performance

FirePhysChem
In this study, cellulose nitrate (NC), a highly energetic polymer, was supplemented with two distinct classes of stabilizing agents: the usual diphenylamine (DPA) and zeolite molecular sieves (ZSM-5) that were ion-exchanged with transition metal ions ...

A microscopic continuum model for defect dynamics in metallic glasses

, 2016
Motivated by results of the topological theory of glasses accounting for geometric frustration, we develop the simplest possible continuum mechanical model of defect dynamics in metallic glasses that accounts for topological, energetic, and kinetic ideas.

Study of the influence of the synthesis process on the sublimation of TATP and HMTD by thermal gravimetric analysis

Chemical Thermodynamics and Thermal Analysis, 2022
The influence of two important parameters in the synthesis of TATP (the type of catalyst and the presence or absence of stirring during the precipitation process) on its sublimation was studied by thermal gravimetric analysis. TATP synthesised with H2SO4
