Journal ArticleDOI
An improved potential energy surface and multi-temperature quasiclassical trajectory calculations of N2 + N2 dissociation reactions
Jason D. Bender,Paolo Valentini,Ioannis Nompelis,Yuliya Paukku,Zoltan Varga,Donald G. Truhlar,Thomas E. Schwartzentruber,Graham V. Candler +7 more
TL;DR: As T(v) decreases, rotational energy appears to compensate for the decline in average vibrational energy in promoting dissociation, and the dissociation probability's dependence on v weakens.
Journal ArticleDOI
Direct molecular simulation of nitrogen dissociation based on an ab initio potential energy surface
Paolo Valentini,Thomas E. Schwartzentruber,Jason D. Bender,Ioannis Nompelis,Graham V. Candler +4 more
TL;DR: In this article, a direct molecular simulation (DMS) approach is used to predict the internal energy relaxation and dissociation dynamics of high-temperature nitrogen molecules by providing forces between the four atoms.
Journal ArticleDOI
Phase-transition plasticity response in uniaxially compressed silicon nanospheres
TL;DR: In this article, a microscopic description of the response of crystalline Si nanospheres up to 10 nm in radius for various uniaxial compression levels is presented, where the behavior at low compressions closely resembles the Hertzian predictions at higher compressions.
Journal ArticleDOI
Dynamics of nitrogen dissociation from direct molecular simulation
TL;DR: In this paper, the coupling between vibrational excitation and dissociation is quantified leading to several new insights, such as the potential energy surface of the vibrational potential energy.

Phase Transition Plasticity Response in Uniaxially Compressed Silicon Nanospheres
TL;DR: A microscopic description for the response of crystalline Si nanospheres up to 10 nm in radius for various uniaxial compression levels challenges the current exclusive view of a dislocation plasticity response in somewhat larger nanoparticles.
