Proton transport through nanoscale corrugations in two-dimensional crystals. [PDF]

Nature, 2023
Defect-free graphene is impermeable to all atoms1,2,3,4,5 and ions6,7 under ambient conditions. Experiments that can resolve gas flows of a few atoms per hour through micrometre-sized membranes found that monocrystalline graphene is completely ...

Proton- versus Cation-Selective Transport of Saccharide Rim-Appended Pillar[5]arene Artificial Water Channels

, 2023
Transport of water across cell membranes is a fundamental process for important biological functions. Herein, we focused our research on a new type of symmetrical saccharide rim-functionalized pillar[5]arene (PA-S) artificial water channels with variable

Interplay of Hydration and Protonation Dynamics in the K-Channel of Cytochrome c Oxidase

Biomolecules, 2022
Cytochrome c oxidase is a membrane protein of the respiratory chain that consumes protons and molecular oxygen to produce water and uses the resulting energy to pump protons across the membrane.

Fatty Acid-Activated Proton Transport by Bisaryl Anion Transporters Depolarises Mitochondria and Reduces the Viability of MDA-MB-231 Breast Cancer Cells

Biomolecules, 2023
In respiring mitochondria, the proton gradient across the inner mitochondrial membrane is used to drive ATP production. Mitochondrial uncouplers, which are typically weak acid protonophores, can disrupt this process to induce mitochondrial dysfunction ...

QM/MM study of proton transport process in [FeFe] hydrogenase enzyme [PDF]

, 2021
Di-iron hydrogenases are a class of enzymes that are capable of reducing protons to form molecular hydrogen with high efficiency. In addition to the catalytic site, these enzymes have evolved dedicated pathways to transport protons and electrons to the ...

Deep-Learning Potentials for Proton Transport in Double-Sided Graphanol [PDF]

, 2023
There is a need to develop new materials for proton exchange mem- branes that can operate at higher temperatures and low humidities. Designing and evaluating novel membrane materials using density func- tional theory (DFT) is infeasible because of length

Enhancement of Proton Transport in an Oriented Polypeptide Thin Film [PDF]

, 2013
Proton transport properties of a partially protonated poly(aspartic acid)/sodium polyaspartate (P-Asp) were investigated. A remarkable enhancement of proton conductivity has been achieved in the thin film. Proton conductivity of 60-nm-thick thin film
