Dynamics of the Galvanic Replacement Reaction of Silver by Gold: Phenomenological Models for Open Circuit Potential‐Time Responsive Indicator

ChemElectroChem, EarlyView.
This article explores the dynamics of replacing three silver atoms by one gold atom (galvanic replacement reaction [GRR]) within silver nanoparticles. The reaction is tracked experimentally using open circuit potential and then mathematically fitted to a sigmoidal kinetic function inspired by autocatalytic and enzymatic cascade reaction functions to ...

Experimental studies on multi‐scale data‐driven methods within the framework of structural health monitoring

Civil Engineering Design, EarlyView.
Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

On Reverse Derivations in d-algebras

European Journal of Pure and Applied Mathematics
In the present paper, we apply the concept of reverse derivation in rings on the concept of d − algebra to obtain the concept called a left-right (resp. right-left) reverse derivations of d−algebra X (briefly, (l, r) resp.

Approximate ternary quadratic derivations on ternary Banach algebras and C*-ternary rings

, 2012
In the current article, we use a fixed point alternative theorem to establish the Hyers-Ulam stability and also the superstability of a ternary quadratic derivation on ternary Banach algebras and C*-ternary rings which is introduced in Shagholi et al ...

Local sensitivity analysis of a supercritical extraction model

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

Estimating strongly wetting to non‐wetting contact angles for pure and mixed liquids on solids by considering film pressure

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In solid–liquid–vapour systems, the effect of film pressure (πe$$ {\pi}_e $$) by vapour adsorbate molecules becomes significant when the solid surface energy is similar to or larger than that of the liquid. We extend Young equation applicability to estimate contact angles of pure and mixed liquids on smooth solids by including πe$$ {\pi}_e $$,

Learning hydrocracking reaction dynamics via neural ODEs: A data‐driven, gradient‐interpretable lumped modelling framework

The Canadian Journal of Chemical Engineering, EarlyView.
This work demonstrates the application of neural ordinary differential equations (neural ODEs) for learning hydrocracking reaction kinetics directly from data, achieving robust predictions under noise and sparsity while preserving mechanistic interpretability through gradient‐based analysis of temperature‐ and concentration‐dependent reaction rates ...
