The evaluation of the temperature effect on the competitiveness between the amine addition and the amidation reaction in a model cure acid-catalysed reaction between the epoxidized methyl oleate (EMO), obtained from high oleic sunflower oil, and aniline is reported. The study was carried out analysing the kinetic profiles of the chemical species involved in the system, which were obtained apply...

We define catalytic networks as chemical reaction networks with an essentially catalytic reaction pathway: one which is "on" in the presence of certain catalysts and "off" in their absence. We show that examples of catalytic networks include synthetic DNA molecular circuits that have been shown to perform signal amplification and molecular logic. Recall that a critical siphon is a subset of the...

Ethanol can initiate Pt nanoparticles to catalyze the chemiluminescent reaction of alkaline lucigenin solution, leading to a visible light emission with autocatalytic property.

Autocatalytic reactions may propagate as solitary waves, namely, at a constant front velocity and with a stationary concentration profile, resulting from a balance between molecular diffusion and chemical reaction. When the reaction is exothermic, a thermal wave is linked to the chemical front. As the thermal diffusivity is nearly two orders of magnitude larger than the molecular one, the tempe...

We model chemical reaction networks as directed hypergraphs that are generated in rule-based manner, using graph grammars as models of given sets of reaction mechanisms. Graphs serve as abstractions of molecules. This provide a level of chemical realism sufficient to ensure conservation of mass, atom type, and charge. Atom maps, for instance, are thus consistently defined within the model. The ...

We investigated a topology of the reaction network for polymerization of amino acids as the emergence and the continuous growth of autocatalytic sets. Reaction networks including transpeptidation reaction can yield newer and longer peptides with time having higher concentrations. Conditions necessary for the occurrence of transpeptidation can be met in actual amino acid/peptide systems.
