Renewable Energy, 2019
CO2 hydrogenation was carried out over a series of Cu/ZnO/Al2O3 catalysts, which were prepared by different synthesis methods (co-precipitation, ultrasound-assisted, sol-gel and solid-state).

Electronic states in oxide superconductors
Physical Review B, 1991Electronic states near the metal-insulator transition in oxide superconductors are studied in the p-d mixing model by use of the Green's-function method. Due to spin and charge fluctuations induced in the p-d hopping, electronic states near the Fermi level are strongly renormalized and show anomalous behavior in the insulator-to-metal transition; that ...

High-Oxidation-State 3d Metal (Ti-Cu) Complexes with N-Heterocyclic Carbene Ligation.
Chemical Reviews, 2018High-oxidation-state 3d metal species have found a wide range of applications in modern synthetic chemistry and materials science. They are also implicated as key reactive species in biological reactions.

Oxide – Oxide Reactions in the Solid State
Current Inorganic Chemistry, 2013The work overviews the reactivity between solid oxides from the fundamental thermodynamic aspects to the diffusion controlled growth of the reaction product, to the reactions at interfaces and the role of surface energy. The final part reports some recent mechanistic achievements concerning the nucleation at the very early stage of a solid-solid ...

Oxidation states of glutathione peroxidase
1984Publisher Summary This chapter discusses a method that has been developed for the reproducible isolation of different oxidized forms of glutathione peroxidase, which can be differentiated by their relative stability and by their reactivity with cyanide.

The oxidation state of sulfur in lunar apatite
American Mineralogist, 2019Lunar apatites contain hundreds to thousands of parts per million of sulfur. This is puzzling because lunar basalts are thought to form in low oxygen fugacity (fO2) conditions where sulfur can only exist in its reduced form (S2–), a substitution not ...

Oxidative state in equine neonates: Anti‐ and pro‐oxidants
Equine Veterinary Journal, 2020Abstract Background In newborns, exposure to the extrauterine environment with high oxygen tension and sudden pulmonary adaptation leads to an increase in reactive oxygen species (ROS). ROS have several physiological roles, which are essential for neonatal development, however, when unbalanced,

1969
It might be argued that the nine first chapters of this book are an expression of an extreme opinion in the inorganic coordination chemist, viz. that most chemical bonds are intrinsically heteropolar and always, at least as a Gedankenexperiment, can be split heterolytically in a coordinating part containing at least one lone-pair; and an electron-pair ...

Analytical chemistry
The analytical utility of chemically modified microelectrodes for oxidation-state speciation of redox couples by cyclic voltammetry has been explored. [Re(I)(DMPE)3]+/[Re(II)(DMPE)3]2+, where DMPE = 1,2-bis(dimethylphosphino)ethane, was studied at carbon-fiber microelectrodes of approximately 5 microm in radius coated with Nafion-entrapped solgel ...
