... Phase Transformations As iron is heated from room-temperature to above its melting point, the following changes in phase occur: • α transforms to γ; • γ transforms to δ; • δ transforms to liquid ... generally required to significantly change phase equilibria for solid metals Under normal conditions, the phase diagram for a pure metal generally needs only a temperature axis The pure iron...

... cooperative metal- binding mech- anisms are possible in which the complete multiple metal- binding site forms in preference to partially filled binding sites. Metallothionein (MT) is a metalloprotein ... divalent metal ions for the a domain are larger than those for the b domain. Further interpretation of these data resulted in the proposal of positively cooperative metal binding as...

... because it was a mono -metal hydride rather than a bi -metal hydride. We felt that it would be easier to reduce a mono -metal hydroxide than to separate and reduce a multi -metal hydroxide. An additional ... An additional consideration is that many of the hydroxides form hydrates. Lithium hydroxide forms a mono-hydrate. Many of the bi -metal hydrides for multi-hydrates when reacted wit...

... the role for metal dyshomeostasis in all aspects is clear. In the AD affected brain, metal dyshomeostasis is evident in the form of a substantial increase in the levels of extracellular metals ... interaction between Ab and these metals can promote the formation of Ab oligo- mers, aggregates and fibrils [48,52–55]. Metal mediated oligomerization of Ab may therefore contribute to the po...
