Trade-offs between number fluctuations and response in nonequilibrium chemical reaction networks [PDF]
, 2023 We study the response of chemical reaction networks driven far from equilibrium to logarithmic perturbations of reaction rates. The response of the mean number of a chemical species is observed to be quantitively limited by number fluctuations as well as the maximum thermodynamic driving force.

Stirring Speeds Up Chemical Reaction [PDF]
, 2021 We consider absorbing chemical reactions in a fluid flow modeled by the coupled advection-reaction-diffusion equations. In these systems, the interplay between chemical diffusion and fluid transportation causes the enhanced dissipation phenomenon. We show that the enhanced dissipation time scale, together with the reaction coupling strength, determines

The Competition between 4-Nitrophenol Reduction and BH4− Hydrolysis on Metal Nanoparticle Catalysts
Molecules, 2023 Assessing competitive environmental catalytic reduction processes via NaBH4 is essential, as BH4− is both an energy carrier (as H2) and a reducing agent. A comprehensive catalytic study of the competition between the borohydride hydrolysis reaction (BHR,

Uncertainty-aware First-principles Exploration of Chemical Reaction Networks [PDF]
J. Phys. Chem. A 2024, 128, 4532-4547, 2023 Exploring large chemical reaction networks with automated exploration approaches and accurate quantum chemical methods can require prohibitively large computational resources. Here, we present an automated exploration approach that focuses on the kinetically relevant part of the reaction network by interweaving (i) large-scale exploration of chemical ...

Chemical reaction planar fronts with a viscoelastic reaction product [PDF]
, 2021 A stress-affected chemical reaction front propagation is considered utilizing the concept of a chemical affinity tensor. A reaction between an elastic solid and diffusing constituents, localized at the reaction front, is considered. As a result of the reaction, the elastic constituent transforms into viscoelastic one.

A generative model for molecule generation based on chemical reaction trees [PDF]
, 2021 Deep generative models have been shown powerful in generating novel molecules with desired chemical properties via their representations such as strings, trees or graphs. However, these models are limited in recommending synthetic routes for the generated molecules in practice. We propose a generative model to generate molecules via multi-step chemical
