Membrane-Modified Metal Triazole Complexes for the Electrocatalytic Reduction of Oxygen and Carbon Dioxide

open access: yesFrontiers in Chemistry, 2018
In this manuscript, an electrochemical architecture is designed that controls the kinetics of proton transfer to metal triazole complexes for electrocatalytic O2 and CO2 reduction.

Potentials of mean force in acidic proton transfer reactions in constrained geometries [PDF]

open access: yes, 2016
Free energy barriers associated with the transfer of an excess proton in water and related to the potentials of mean force in proton transfer episodes have been computed in a wide range of thermodynamic states, from low-density amorphous ices to high ...

Parametrizing reaction probabilities for proton transfers in protic ionic liquids

open access: yesFrontiers in Chemistry
Protic ionic liquids are promising electrolytes for electrochemical applications owing to their intrinsic proton conductivity, but quantitative understanding of the underlying proton transfer processes remains limited.

Dynamics of Proton Transfer in Mesoscopic Clusters

open access: yes, 1996
Proton transfer rates and mechanisms are studied in mesoscopic, liquid-state, molecular clusters. The proton transfer occurs in a proton-ion complex solvated by polar molecules comprising the cluster environment.

Structures and proton-pumping strategies of mitochondrial respiratory enzymes [PDF]

open access: yes, 2001
Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the energy made available from electron transfer reactions to transport protons across the inner mitochondrial membrane and create an electrochemical gradient used for the ...

Coulomb effects in polarization transfer in elastic antiproton and proton electron scattering at low energies

open access: yes, 2007
The influence of Coulomb distortion on the polarization transfer in elastic proton and antiproton electron scattering at low energies is calculated in a distorted wave Born approximation.

Visualizing the protons in a metalloenzyme electron proton transfer pathway [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
In redox metalloenzymes, the process of electron transfer often involves the concerted movement of a proton. These processes are referred to as proton-coupled electron transfer, and they underpin a wide variety of biological processes, including respiration, energy conversion, photosynthesis, and metalloenzyme catalysis.
