Earth’s surface environment is largely influenced by its budget of major volatile elements: carbon (C), nitrogen (N), and hydrogen (H). Although the volatiles on Earth are thought to have been delivered by chondritic materials, the elemental composition of the bulk silicate Earth (BSE) shows...
reducedtitaniteIon adsorption rare earth element (REE) deposits in southern China are the exclusive source of heavy REEs (HREEs) in the world, and this HREE-enriched character of the deposits is inherited from the REE compositions of the underlying granitic rocks. Such HREE-enriched rocks form ...
- loses electrons and is oxidized, and the oxidant or oxidizing agent gains electrons and is reduced. The pair of an oxidizing and reducing agent that...- Oxidization may refer to: Oxidation, a chemical reaction in which electrons are lost Beta oxidation, the process by which fatty acids ...
The reduced nature of aqueous fluids released from subducting ultramafic rocks affects the recycling capacity of redox-sensitive elements to arc magmas and the convecting mantle. The interaction of seawater with peridotites leads to an enrichment of U in serpentinites42. Recent findings on the trace...
An additional difference is observed in the secondary structure elements that include the ligand histidine residues. In the arthropod Hcs, both CuA and CuB are coordinated by the histidines belonging to a two α-helices motive. In contrast, in the Hcs from molluscs, only the CuB is coordinated...

The properties of epitaxial silicene monolayers on Ag(111) at various levels of oxidation are determined through complementary density functional theory calculations and soft X-ray spectroscopy experiments. Our calculations indicate that moderate levels of oxidation do not cause a significant bandgap opening...
(b) The average values of the functional parameters: core height (Sk), reduced peak height (Spk), and reduced valley depth (Svk) for uncoated and coated specimens. (c) The calculated surface texture direction values showed mixed structure for all modified specimens. (d) Surface topographies ...
