Molecular simulation study of the stabilization process of NEPE propellant
Defence Technology, 2023 In this reported study, the density functional theory (DFT) was used at the (U)B3LYP/6-311G(d,p) level to investigate the stabilization process of the nitrate ester plasticized polyether propellant (NEPE).

Self-Reproduction and Darwinian Evolution in Autocatalytic Chemical Reaction Systems
Life, 2021 Understanding the emergence of life from (primitive) abiotic components has arguably been one of the deepest and yet one of the most elusive scientific questions.

Scientific Reports, 2023 Autocatalysis is a crucial process of nonequilibrium self-organization in nature and is assumed to play a role in the origin of life. The essential dynamical phenomena of an autocatalytic reaction network are bistability and the development of ...

Nature Communications, 2021 So far, only a few chemical oscillators based on organic reactions have been developed. Here, the authors report both autocatalytic and oscillatory reaction networks that form substituted guanidines from thiouronium salts; when coupled to cascade ...

Convective fingering of an autocatalytic reaction front [PDF]
Physical Review E, 1996 We report experimental observations of the convection-driven fingering instability of an iodate-arsenous acid chemical reaction front. The front propagated upward in a vertical slab; the thickness of the slab was varied to control the degree of instability. We observed the onset and subsequent nonlinear evolution of the fingers, which were made visible

Cure Kinetics of Epoxy-Novolac Resin Containing Tetrabromo-bisphenol-A as a Flame Retardant by Isothermal Calorimetry Method [PDF]
علوم و تکنولوژی پلیمر, 2014 Cure kinetics of an epoxy-novolac resin with tetrabromo-bisphenol-A, as a flame retardant, was investigated in the presence of nadic methyl anhydride as a curing agent. Different amounts of benzyl dimethyl amine were used as accelerator.

A Crank-Nicolson Method of Autocatalytic Reaction-Diffusion Systems [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2006 In this paper we used two numerical methods to investigate propagating heat solutions of PDEs. The explicit and Crank-Nicolson methods and the results show that Crank-Nicolson method is more accurate than the explicit method.
