Hmx Polymorphism: Virtual Melting Growth Mechanism, Cluster-to-cluster Nucleation Mechanism and Physically Based Kinetics

Coupled phase transformation, chemical decomposition, and deformation in plastic-bonded explosive: Models

A continuum thermomechanochemical model of the behavior of a plastic-bonded explosive PBX 9501 formulation consisting of the energetic crystal octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine HMX embedded in a polymeric binder is developed. Our main focus is on the study of the ↔ phase transformations PTs in crystalline HMX under a complex pressure-temperature path. To reproduce the pressure-te...

Solid-solid phase transformation via internal stress-induced virtual melting, significantly below the melting temperature. Application to HMX energetic crystal.

We theoretically predict a new phenomenon, namely, that a solid-solid phase transformation (PT) with a large transformation strain can occur via internal stress-induced virtual melting along the interface at temperatures significantly (more than 100 K) below the melting temperature. We show that the energy of elastic stresses, induced by transformation strain, increases the driving force for me...

A Cluster-Based Hybrid broadcasting mechanism for Quantum Systems with Power Management and delay Constraint in the MAC sub-layer

An empirical technique for prediction of nucleation mechanism and interfacial tension of potassium chloride nanoparticles

Prediction of the nucleation mechanism is one of the most critical factors in the design of a crystallization system. Information about the nucleation mechanism helps to control the size, shape, size distribution, and purity of the produced crystals. When the crystallization method is used for producing nanoparticles, the nucleation mechanism should be predicted. In this study, an empirical cor...

Modeling particle formation during low-pressure silane oxidation: Detailed chemical kinetics and aerosol dynamics

A detailed chemical kinetic model is presented for silicon oxide clustering that leads to particle nucleation during low-pressure silane oxidation. Quantum Rice–Ramsperger–Kassel theory was applied to an existing high-pressure silane oxidation mechanism to obtain estimates for the pressure dependence of rate parameters. Four classes of clustering pathways were considered based on current knowle...
