Multiple-peak traveling waves of the Gray-Scott model

open access: yesMathematics 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 ...

Mechanisms of Autocatalysis

open access: yesAngewandte Chemie International Edition, 2013
AbstractSelf‐replication is a fundamental concept. The idea of an entity that can repeatedly create more of itself has captured the imagination of many thinkers from von Neumann to Vonnegut. Beyond the sciences and science fiction, autocatalysis has found currency in economics and language theory, and has raised ethical fears memorably summed up by the

Modelling Bacteria-Inspired Dynamics with Networks of Interacting Chemicals

open access: yesLife, 2019
One approach to understanding how life-like properties emerge involves building synthetic cellular systems that mimic certain dynamical features of living cells such as bacteria.

On the Emergence of Autonomous Chemical Systems through Dissipation Kinetics

open access: yesLife, 2023
This work addresses the kinetic requirements for compensating the entropic cost of self-organization and natural selection, thereby revealing a fundamental principle in biology.

Anion–π catalysis on carbon allotropes

open access: yesBeilstein 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

The Effect of Ingredients Mixing Sequence in Rubber Compounding upon Vulcanization Kinetics of Natural Rubber: An Autocatalytic Model Study

open access: yesIndonesian Journal of Chemistry, 2018
This study examined the effect of ingredients mixing sequence to the vulcanization kinetics of natural rubber. The effects of mixing temperature, vulcanization temperature, and the carbon black type upon the kinetics were also studied by using rheography

Chemical Ecosystem Selection on Mineral Surfaces Reveals Long-Term Dynamics Consistent with the Spontaneous Emergence of Mutual Catalysis

open access: yesLife, 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 ...

Platinum Group Metals: A Review of Resources, Production and Usage with a Focus on Catalysts

open access: yesResources, 2021
The major applications of PGMs are as catalysts in automotive industry, petroleum refining, environmental (gas remediation), industrial chemical production (e.g., ammonia production, fine chemicals), electronics, and medical fields.
