The adsorption of oxygen on the W(001) surface has been studied by LEED, AES, and low energy alkali ion scattering in order to obtain a more detailed understanding of the short-range surface structure. Exposure at room temperature results in oxygen adsorption near bridge sites for all coverage...
1 obtained a value of 4.44 Bohr magnetons (B.M.) for its effective magnetic moment at room temperature in aqueous solution and showed that on oxygenation it became almost diamagnetic with the absorption of one oxygen molecule for two cobalt atoms. For three unpaired electrons the spin-only ...

Photosystem II (PS II) of thylakoid membrane of photosynthetic organisms has drawn attention of researchers over the years because it is the only system on Earth that provides us with oxygen that we breathe. In the recent past, structure of PS II has been the focus of research in plant scie...
Quantum chemical calculations and simulated kinetics were used to examine the structure sensitivity of the oxygen evolution reaction on several surface terminations of Co3O4. Active sites consisting of two adjacent Co(IV) cations connected by bridging oxos were identified on both the (001) and (31...
γ-Al2O3 is one of the most widely used catalysts or catalyst supports in numerous industrial catalytic processes. Understanding the structure of γ-Al2O3 is essential to tuning its physicochemical property, which still remains a great challenge. We repo
In this interactive, you can explore the structure of atoms as you add protons, neutrons, or electrons to a model and the name of the element you have created will appear. You can also see the net charge, the mass number, whether it is stable or unstable, and whether it is an ion ...
For most living beings, oxygen is an essential molecule for survival, being the basis of biological oxidations, which satisfy most of the energy needs of aerobic organisms. Oxygen can also behave as a toxic agent posing a threat to the existence of livin
