“…Carbon nanostructures in the reaction zone were obtained. Filamentary structures found in conserved detonation products 43,44 can be the remnants of fractal structures formed at condensation in the region of chemical peak. Hence, we can suppose that long carbon filaments of the diameter of 10-40 nm exist in the detonation wave.…”

Based on the analysis of the data on the behavior of electric conductivity at the detonation of condensed high explosives (HEs) with the composition CHNO and the carbon mass fraction higher than 0.1, the conclusion was made of the presence of long carbon nanostructures. These structures penetrate all the space of reacting HE. The structures are formed already in the chemical peak region, and they evolve along the detonation wave.

“…1-10 km/s), which drive the sample to high T and p; the transient nature of these experiments precludes measurement of properties as fundamental as system temperature. Simulating soot formation from carbon rich materials is also difficult, owing to spatial and temporal domains that can exceed 10 nm and ns, respectively 6,7 . Consequently, relatively little is understood about how these particulates form at short times 1,[8][9][10] .…”

<p>We have developed a transferable reactive force field for C/O systems under extreme temperature and pressure conditions based on the many-body Chebyshev Interaction Model for Efficient Simulation (ChIMES). The resulting model is shown to recover much of the accuracy of DFT for prediction of structure, dynamics and chemistry when applied to dissociative systems at 1:1 and 1:2 C:O ratios, as well as molten carbon. Our C/O modeling approach exhibits a 10<sup>4</sup> increase in efficiency and linear system size scalability over standard quantum molecular dynamics methods, allowing simulation of significantly larger systems than previously possible. Furthermore, we show that system sizes of at least 500 atoms are required to observe the formation of experimentally predicted molten carbon condensates under oxygen-deficient conditions, indicative of possible system size effects in quantum simulations of these types of systems. Overall, we find the present ChIMES model to be well suited for modeling chemical processes and cluster formation at pressures and temperatures typical of shock waves. We expect that the present C/O modeling paradigm can serve as a template for the development of a high pressure --high temperature organic chemistry force-field. </p>
