The diatomic molecules and ions, CO, N2, CN NO and O2, can bond to transition metals. Isoelectronic CO, N2 and CN, with ten valence-shell electrons, have triple bonds and no unpaired electrons in...doi:10.1007/978-3-642-93216-8_18R. D. Harcourt...
The 5 %BaCoO3-CeO2 sample remains NTN2 71.1 % at 800 °C in the presence of 1 vol% O2. In BaCoO3-CeO2 sample, BaCoO3 is proved as the primary active sites to adsorb NO, while CeO2 improves the reducibility, oxygen mobility and sintering resistance [20]. The morphology o...
However, these reactions invariably result in the generation of reactive oxygen species (ROS) compounds that are unstable by having final layer of electrons unpaired and that, in trying to stabilize itself sequester electrons from other biomolecules, making them also destabilizes and, therefore, is ...
is a major factor driving mortality risk1. Inhibitors of the renin-angiotensin system are first line therapies administered upon clinical presentation of DKD2. Although recent figures suggest a stabilisation in the prevalence of DKD3, current therapies only slow...

Moreover, Cu2+ was favorable for the CO adsorption, while the unpaired electrons in the CeO2-Al2O3 support were favorable for the adsorption of NO. 2.1.2. Bimetallic Catalysts Chen et al. [43] synthesized a series of CuCoOx/TiO2 catalysts and found that the CuCoOx/TiO2 catalyst able ...

Coordinately unsaturated iron(II) porphyrins form two sigma bonds with ·O2·(-ΔGBF = 1–6 kcal mol-1) via two of the four unpaired d-electrons of the iron center. The hydroxyl radical ${m H}^+_2 {m O}\\\cdot /{m HO}\\\cdot$ couples with an unpaired electron of the PM(II...
Calculations (B3PW91/6-311+G(3df)) show that the structural units in [O2SSSSO2]2– are joined by the interaction of electrons in two mutually perpendicular π* SOMOs of the triplet-state diradical S2 with unpaired electrons in the π*-antibonding orbitals of the two terminal [SO2]•–...
The nature of interactions and the bonding properties have been studied using a hybrid variational–peturbational scheme, natural bond orbital and atoms in molecule techniques. The hydrogen bonding in the complexes is of covalent nature and is only weakly influenced by the unpaired electrons of ...
