The SIR dynamic model of infectious disease transmission and its analogy with chemical kinetics [PDF]

PeerJ Physical Chemistry, 2020
Mathematical models of the dynamics of infectious disease transmission are used to forecast epidemics and assess mitigation strategies. In this article, we highlight the analogy between the dynamics of disease transmission and chemical reaction kinetics ...

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

On RAF Sets and Autocatalytic Cycles in Random Reaction Networks

, 2014
The emergence of autocatalytic sets of molecules seems to have played an important role in the origin of life context. Although the possibility to reproduce this emergence in laboratory has received considerable attention, this is still far from being ...

Spatiotemporal pattern formation in a three-variable CO oxidation reaction model [PDF]

, 2018
The spatiotemporal pattern formation is studied in the catalytic carbon monoxide oxidation reaction that takes into account the diffusion processes over the Pt(110) surface, which may contain structurally different areas. These areas are formed during CO-

Kinetic analysis of ligand-induced autocatalytic reactions [PDF]

Biochemical Journal, 2004
Protein phosphorylation and limited proteolysis are two most common regulatory mechanisms involving the energy-dependent covalent modification of regulatory enzymes. In addition to modifying other proteins, many protein kinases and proteases catalyse automodification reactions (i.e. reactions in which the kinase or zymogen serves as its own substrate),

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

Advanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Complete homochirality induced by the nonlinear autocatalysis and recycling

, 2003
A nonlinear autocatalysis of a chiral substance is shown to achieve homochirality in a closed system, if the back-reaction is included. Asymmetry in the concentration of two enantiomers or the enantiometric excess increases due to the nonlinear ...

Non-Equilibrium Thermodynamics View on Kinetics of Autocatalytic Reactions—Two Illustrative Examples

Molecules, 2021
Autocatalytic reactions are in certain contrast with the linear algebra of reaction stoichiometry, on which rate equations respecting the permanence of atoms are constructed. These mathematical models of chemical reactions are called conservative.

The Electrochemical Peroxydisulfate-Oxalate Autocatalytic Reaction

Journal of the American Chemical Society
Aqueous solutions containing both the strong oxidant, peroxydisulfate (S2O82‒), and the strong reductant, oxalate (C2O42‒), are thermodynamically unstable due to the highly exothermic homogeneous redox reaction: S2O82‒ + C2O42‒ ® 2 SO42‒ + 2 CO2 (DG0 = −490 kJ/mol). However, at room temperature, this reaction does not occur to a significant extent over
