Inverse spinel structures have a different cation distribution in that all of the A cations and half of the B cations occupy octahedral sites, while the other half of the B cations occupy tetrahedral sites. An example of an inverse spinel is Fe 3 O 4, if the Fe 2+ (A 2+) ions are d 6 high-spin and the Fe 3+ (B 3+) ions are d 5 high-spin.
Polyhedral representation of spinel MgAl 2 O 4. Spinel (/ s p ɪ ˈ n ɛ l, ˈ s p ɪ n əl / [7]) is the magnesium/aluminium member of the larger spinel group of minerals. It has the formula MgAl 2 O 4 in the cubic crystal system. Its name comes from the Latin word spinella, a diminutive form of spine, in reference to its pointed crystals. [5]
Maghemite (Fe 2 O 3, γ-Fe 2 O 3) is a member of the family of iron oxides.It has the same formula as hematite, but the same spinel ferrite structure as magnetite (Fe 3 O 4) and is also ferrimagnetic.
The definition of high-entropy oxide is debated. In oxide literature, the term is commonly used to refer to any oxide with at least five principal cations. [42] However, it has been suggested that this is a misnomer, as most reports neglect to calculate configurational entropy. [42]
The term Southern Cross can also refer to the blue saltire as used in various flags of the Confederate States of America in the American Civil War. [ 1 ] This list is an incomplete list and some of the flags in this list might not have official status.
TRPV is a family of transient receptor potential cation channels (TRP channels) in animals. All TRPVs are highly calcium selective. TRP channels are a large group of ion channels consisting of six protein families, located mostly on the plasma membrane of numerous human and animal cell types, and in some fungi. [2]
