A Proton-coupled electron transfer (PCET) is a chemical reaction that involves the transfer of electrons and protons from one atom to another. The term was originally coined for single proton, single electron processes that are concerted, [1] but the definition has relaxed to include many related processes.
The other area in which Nocera is considered a pioneer is proton-coupled electron transfer (PCET). While he did not originate the idea that electron transfer and proton transfer could be studied as coupled processes, he published one of the foundational papers demonstrating a model for such study in 1992.
This chemical reaction is promoted by 1-electron oxidation of indole-3-acetate through a proton-coupled electron transfer (PCET), which requires the transfer of the indolic-NH proton to a suitably positioned base, producing an indoleacetate anion radical intermediate.
Hammes-Schiffer's work delves primarily into three separate areas of chemistry: Proton-coupled electron transfer (PCET), Enzymatic Processes, and the Nuclear-Electronic Orbital method. [17] A part of this research engages in the study of the Kinetic isotope effect, a difference in the reaction rate of a chemical based on what isotope is present.
Elementary steps like proton coupled electron transfer and the movement of electrons between an electrode and substrate are special to electrochemical processes. . Electrochemical mechanisms are important to all redox chemistry including corrosion, redox active photochemistry including photosynthesis, other biological systems often involving electron transport chains and other forms of ...

Collins (born 1965) United States "for pioneering work on synthetic gene circuits, which launched the field of synthetic biology."
• For breakthrough research on proton-coupled electron transfer (PCET) reactions and enzymatic processes that have provided new strategies for designing light-harvesting assemblies for solar energy conversion.
In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor).
