Development of Reactive Force Field for DNTF and Molecular Dynamics Simulation of Reaction Mechanism under Shock Loading
3,4-Dinitrofurazanfuroxan (DNTF) is a typical hydrogen-free
furazan
compound with good casting performance. A rapid chemical reaction
under shock loading causes the high impact sensitivity of DNTF. However,
the details of the reaction remain unclear. Currently, there is no
suitable reactive force field (ReaxFF) for simulating the reaction
under shock loading because the existing ReaxFF parameters cannot
accurately reproduce the structure of furazan during relaxation at
room temperature. Therefore, the ReaxFF parameters are reoptimized
using a program designed by ourselves based on the training set that
takes into account the structure and decomposition products of DNTF.
The obtained ReaxFF accurately describes the structure of the DNTF
molecule. A method is proposed to number molecules, groups, and atoms
and track the reaction path of each atom to obtain the cleavage and
formation of bond. The furoxan N–O bond breaks first, which
is the trigger bond. Subsequently, the C-NO2 group dissociates,
and the N–O bonds in the furazan break. Cleavage of the furoxan
trigger bond, furazan opening, and C-NO2 dissociation are
the main initial decomposition mechanisms of the reaction, and the
order of reaction activation energy was C-NO2 ≈
furazan ring > furoxan ring. The rapid formation of N–N
and
C–O bonds after the ring opening and C-NO2 dissociation
is the main reason for the rapid increase in temperature

Table1_Establishment of an efficient regeneration and Agrobacterium transformation system in mature embryos of calla lily (Zantedeschia spp.).XLSX
Calla lily (Zantedeschia spp.) have great aesthetic value due to their spathe-like appearance and richness of coloration. However, embryonic callus regeneration is absent from its current regeneration mechanism. As a result, constructing an adequate and stable genetic transformation system is hampered, severely hindering breeding efforts. In this research, the callus induction effectiveness of calla lily seed embryos of various maturities was evaluated. The findings indicated that mature seed embryos were more suitable for in vitro regeneration. Using orthogonal design experiments, the primary elements influencing in vitro regeneration, such as plant growth regulators, genotypes, and nanoscale materials, which was emergent uses for in vitro regeneration, were investigated. The findings indicated that MS supplemented with 6-BA 2Â mg/L and NAA 0.1Â mg/L was the optimal medium for callus induction (CIM); the germination medium (GM) was MS supplemented with 6-BA 2Â mg/L NAA 0.2Â mg/L and 1Â mg/L CNTs, and the rooting medium (RM) was MS supplemented with 6-BA 2Â mg/L NAA 0.7Â mg/L and 2Â mg/L CNTs. This allowed us to verify, in principle, that the Agrobacterium tumefaciens-mediated genetic transformation system operates under optimal circumstances using the GUS reporter gene. Here, we developed a seed embryo-based genetic transformation regeneration system, which set the stage for future attempts to create new calla lily varieties.</p
