Modeling and simulating chemical reactions [PDF]

open access: yesSIAM Review, 2008
Many students are familiar with the idea of modeling chemical reactions in terms of ordinary differential equations. However, these deterministic reaction rate equations are really a certain large-scale limit of a sequence of finer-scale probabilistic ...

The Interaction Pathway in the Mechano-Ultrasonically Assisted and Carbon-Nanotubes Augmented Nickel–Aluminum System

open access: yesMetals, 2022
The influence of mechano-ultrasonic activation (MUA) and nano-additives (carbon nanotubes-CNT) on the interaction pathway of nickel–aluminum powder mixture at high heating rates was investigated.

Chemical master equation and Langevin regimes for a gene transcription model [PDF]

open access: yes, 2007
Gene transcription models must take account of intrinsic stochasticity. The Chemical Master Equation framework is based on modelling assumptions that are highly appropriate for this context, and the Stochastic Simulation Algorithm (also known as ...

Chemical master versus chemical langevin for first-order reaction networks [PDF]

open access: yes, 2008
Markov jump processes are widely used to model interacting species in circumstances where discreteness and stochasticity are relevant. Such models have been particularly successful in computational cell biology, and in this case, the interactions are ...

The Competition between 4-Nitrophenol Reduction and BH4 Hydrolysis on Metal Nanoparticle Catalysts

open access: yesMolecules, 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,

A millifluidic calorimeter with InfraRed thermography for the measurement of chemical reaction enthalpy and kinetics [PDF]

open access: yes, 2008
The aim of this work is to present an infrared calorimeter for the measurement of the kinetics and the enthalpy of high exothermic chemical reactions. The main idea is to use a millifluidic chip where the channel acts as a chemical reactor.
