Two classes of quasi-steady-state model reductions for stochastic kinetics [PDF]

open access: yes, 2007
The quasi-steady-state approximation (QSSA) is a model reduction technique used to remove highly reactive species from deterministic models of reaction mechanisms.

Theoretical Study of Solvent Effects on the Platinum-Catalyzed Oxygen Reduction Reaction [PDF]

open access: yes, 2010
We report here density functional theory (DFT) studies (PBE) of the reaction intermediates and barriers involved in the oxygen reduction reaction (ORR) on a platinum fuel cell catalyst.

A Unified Approach to CO2–Amine Reaction Mechanisms

open access: yesACS Omega, 2020
A unified CO2–amine reaction mechanism applicable to absorption in aqueous or nonaqueous solutions and to adsorption on immobilized amines in the presence of both dry and humid conditions is proposed.

Role of direct and resonant (compound state) processes and of their interferences in the quantum dynamics of the collinear H + H2 exchange reaction [PDF]

open access: yes, 1973
The question of the relative importance of compound state (i.e., activated complex) and direct reaction mechanisms has been of central importance for the dynamical foundations of chemical kinetics [1,2].

Impact of receiver reaction mechanisms on the performance of molecular communication networks [PDF]

open access: yes, 2013
In a molecular communication network, transmitters and receivers communicate by using signalling molecules. At the receivers, the signalling molecules react, via a chain of chemical reactions, to produce output molecules.

A Minireview: The Mechanism of H2O2 Photoproduction by Graphitic Carbon Nitride

open access: yesAdvanced Energy & Sustainability Research, 2023
Hydrogen peroxide (H2O2) is extensively used in production and life, functioning as an ecofriendly oxidant. However, the dominant method currently employed, the anthraquinone method, is not conducive to sustainable development.

Free radicals, natural antioxidants, and their reaction mechanisms

open access: yes, 2015
The normal biochemical reactions in our body, increased exposure to the environment, and higher levels of dietary xenobiotic's result in the generation of reactive oxygen species (ROS) and reactive nitrogen species (RNS). The ROS and RNS create oxidative

Elucidating reaction mechanisms on quantum computers [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Our work addresses the question of compelling killer applications for quantum computers. Although quantum chemistry is a strong candidate, the lack of details of how quantum computers can be used for specific applications makes it difficult ...

Damage of polyesters by the atmospheric free radical oxidant NO3•: a product study involving model systems

open access: yesBeilstein Journal of Organic Chemistry, 2013
Manufactured polymer materials are used in increasingly demanding applications, but their lifetime is strongly influenced by environmental conditions. In particular, weathering and ageing leads to dramatic changes in the properties of the polymers, which
