Multiple-peak traveling waves of the Gray-Scott model
Mathematics in Applied Sciences and Engineering, 2023 We study a reaction-diffusion system which models the pre-mixed isothermal autocatalytic chemical reaction of order m (m > 1) between two chemical species, a reactant A and an auto-catalyst B, A + m B --> (m+1) B, and a linear decay B -->C, where C ...

Robust Adaptation and Homeostasis by Autocatalysis [PDF]
The Journal of Physical Chemistry B, 2012 Robust homeostatic mechanisms are essential for the protection and adaptation of organisms in a changing and challenging environment. Integral feedback is a control-engineering concept that leads to robust, i.e., perturbation-independent, adaptation and homeostatic behavior in the controlled variable. Addressing two-component negative feedback loops of

Anion–π catalysis on carbon allotropes
Beilstein Journal of Organic Chemistry, 2023 Anion–π catalysis, introduced in 2013, stands for the stabilization of anionic transition states on π-acidic aromatic surfaces. Anion–π catalysis on carbon allotropes is particularly attractive because high polarizability promises access to really strong

Life, 2019 How did chemicals first become organized into systems capable of self-propagation and adaptive evolution? One possibility is that the first evolvers were chemical ecosystems localized on mineral surfaces and composed of sets of molecular species that ...

Autocatalysis and organocatalysis with synthetic structures [PDF]
Proceedings of the National Academy of Sciences, 2009 The discovery of ribozymes led to the proposal of an RNA world, where a single type of molecule was supposedly capable of self-replication and chemical catalysis. We show here that both autocatalysis and organocatalysis can be engineered into a synthetic structure.
