Energetics and thermodynamic stability of potential Fe(II)‐hexa‐aza‐active sites for O2 reduction in PEM fuel cells

SusMat, 2022
We present here a thermodynamic assessment of the stability behavior in acid environment at 298 and 353 K (80°C) of two iron (II) hexa‐aza‐macrocyclic complexes and of an hexa‐aza‐iron‐based site (FeIIN(4+2)/C) that should potentially be active for the ...

A model for transition of 5 '-nuclease domain of DNA polymerase I from inert to active modes [PDF]

, 2011
Bacteria contain DNA polymerase I (PolI), a single polypeptide chain consisting of similar to 930 residues, possessing DNA-dependent DNA polymerase, 3'-5' proofreading and 5'-3' exonuclease (also known as flap endonuclease) activities.

Achievements and challenges of copper‐based single‐atom catalysts for the reduction of carbon dioxide to C2+ products

Exploration, 2023
Copper is the only metal that can convert CO2 into C2 and C2+ in electrocatalytic carbon dioxide reduction (CO2RR). However, the Faraday efficiency of CO2 conversion to C2 and C2+ products at high current densities is still low, which cannot meet the ...
