Oxygen has an oxidation state of −2 in most of its compounds. It forms a large range of covalently bonded compounds, among which are oxides of nonmetals, such as water (H2O), sulfur dioxide (SO2), and carbon dioxide (CO2); organic compounds such as alcohols, aldehydes, and carboxylic...

The application of NO increases the turnover time of the oxygen evolving centers, i.e., it delays the process of the electron donation or Si states turnover, which could be the result of structural reorganizations, which affect the interactions between PSII and its antenna complexes after NO ...
its extent precludes motility, an additional source of oxidative stress. Sessile life form and the lack of neuronal systems, however, limit options for mate recognition and adult sexual selection, resulting in inefficient mate-searching systems. Hence, sessility requires that all individuals can produc...
2A), implying that the proportion of individual brGDGT compounds, along with brGDGT-based proxies, remained largely consistent irrespective of whether the values were from the surface, bottom, or averaged across the core.

(OVs) refers to the vacancy formed by the separation of oxygen atoms (oxygen ions) in the lattice inmetal oxidesor other compounds containing oxygen. In simple terms, it refers to the defect left by the oxygen ion escaping from its lattice, and the defect equation can be expressed by Eq....
Lignocellulosic biomass, the most abundant and inexpensive renewable feedstock on the planet, has a great potential for sustainable production of fuels, chemicals, and carbon-based materials. Fast pyrolysis integrated with hydrotreating, one of the simplest, most cost-effective, and most efficient ...
