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.

Exploiting limited valence patchy particles to understand autocatalytic kinetics [PDF]
, 2018 Autocatalysis, i.e., the speeding up of a reaction through the very same molecule which is produced, is common in chemistry, biophysics, and material science. Rate-equation-based approaches are often used to model the time dependence of products, but the

Reducing Iron Oxide with Ammonia: A Sustainable Path to Green Steel
Advanced Science, 2023 Iron making is the biggest single cause of global warming. The reduction of iron ores with carbon generates about 7% of the global carbon dioxide emissions to produce ≈1.85 billion tons of steel per year. This dramatic scenario fuels efforts to re‐invent

Continual reproduction of self-assembling oligotriazole peptide nanomaterials. [PDF]
, 2017 Autocatalytic chemical reactions, whereby a molecule is able to catalyze its own formation from a set of precursors, mimic nature's ability to generate identical copies of relevant biomolecules, and are thought to have been crucial for the origin of life.

Switching Dynamics in Reaction Networks Induced by Molecular Discreteness [PDF]
, 2006 To study the fluctuations and dynamics in chemical reaction processes, stochastic differential equations based on the rate equation involving chemical concentrations are often adopted. When the number of molecules is very small, however, the discreteness
