Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated. Here we discuss the processes that distributed th
inner coreThe stable phase of iron ( Fe) in the Earth's core has been the subject of extensive studies, yet still remains controversial. Hexagonal close-packed structure (hcp) is the accepted stable form of pure Fe; however, it has been recently proposed that a body-centered-cubic (bcc)...
Moreover, it is generally supposed that the wave velocities observed in seismic data from the core imply an inner core density lower than that of pure iron25,26,27. This suggests the existence of ‘light’ elements as the major alloying candidates within it, such as H, C, O, S and Si...
Rare earth element geochemistry in the inner shelf of the East China Sea and its implication to sediment provenances Gravity core EC2005, located in the mud wedge off the Zhejiang-Fujian coast in the inner shelf of the East China Sea (ECS), was analyzed for its lithology,... Fangjian XU...
Heavy metals,OM,TN,C/N and TP were investigated from the TE core sediments of Talahong sub-lake in Lianhuan Lake,which represented the concentration history of heavy metals and nutrient elements,and the possible influencing factors were analyzed.Furthermore,cluster analysis was applied to find out...
All of the electrons of the noble gases are considered to be core electrons because all of the electron shells are filled. It is for this reason that... Learn more about this topic: Electron Configurations in the s, p & d Orbitals ...
The inner core of the business should implement the basic elements of training, integrity, teamwork, leadership, and ethics. If the entire business contains these key essentials, it is likely that the customers will be extremely pleased with the products and services that the business offers. ...
Constraining the core's composition is essential for understanding Earth accretion, core formation and the sustainment of Earth's magnetic field. Earth's outer and inner core exhibit a density deficit relative to pure iron, attributed to the presence of substantial amounts of low atomic number 'li...
