The electronic structure of ZnO is also affected by the charge transfer between the VB or CB of ZnO and the 4f or 5d electrons of RE metals. Although RE doping provides some advantages, this technique is limited by the low doping saturation of RE ions in the ZnO crystal lattice because ...
The iShares Transition-Enabling Metals ETF (the “Fund”) seeks to track the investment results of an index that provides exposure to metals that are essential to a wide range of clean energy technologies supporting the transition to a low-carbon economy
Anode materials for SIBs have undergone comprehensive research, in which specific types include: i) carbon-based and titanium-based materials utilising intercalation reaction mechanisms; ii) main group metals such as Sn, Sb and Bi based on alloy reaction mechanisms; and iii) transition metal compound...
