S-state cycle for water oxidation and oxygen evolution. In the latest and highest-resolution structure113 the central unit for the oxidation of water is a Mn4CaO5 cluster on the lumenal side of the membrane containing four manganese ions, a calcium ion and two chloride ions (Figure 12). ...

Adsorption of nitrogen, oxygen, and argon on cobalt(II)-exchanged zeolite X at 288.2 and 303.0 K was studied. The nitrogen and oxygen adsorption capacities increase upon cobalt ion exchange up to 71%, beyond which it shows a decreasing trend because of the partial degradation of the zeolite ...
We study the nature of the electron pairing at the most important critical points of the singlet potential energy surface of the 2O2 ⇆ O4 reaction and its evolution along the reaction coordinate using the electron pair localization function (EPLF) [Scemama, A.; Chaquin, P.; Caffarel, M....

Knowledge of the exact nature of the iron-oxygen bond in oxyhaemoglobin (oxyHb) is essential for the understanding of cooperative oxygen binding to haemoglobin (Hb). However, X-ray studies of oxyHb have previously been hindered by the tendency of oxyHb crystals to autoxidize. Here we report...
Taking a hydrogen and oxygen reaction in a PEM fuel cell producing liquid water as an example (as in Eq. 1.1) to calculate the standard molar reaction enthalpy of 1 mol hydrogen: (1.8)dHr0=Hf,H2O(l)0−Hf,H20−12Hf,O20=−285.85kJmol−1where dHr0 is the standard molar ...
