This chapter focuses on transition metals. All transition metal cations are toxic—those that are essential for Escherichia coli and belong to the first transition period of the periodic system of the element and also the "toxic-only" metals with higher atomic numbers.

Metal to semiconductor transition in metallic transition metal dichalcogenides
Journal of Applied Physics, 2013We report on tuning the electronic and magnetic properties of metallic transition metal dichalcogenides (mTMDCs) by 2D to 1D size confinement. The stability of the mTMDC monolayers and nanoribbons is demonstrated by the larger binding energy compared to the experimentally available semiconducting TMDCs. The 2D MX2 (M = Nb, Ta; X = S, Se) monolayers are

Metal-insulator transition in transition metal oxides
Journal of Physics C: Solid State Physics, 1971Electronic band structure calculations for TiO, VO, MnO, FeO, CoO, and NiO suggest that the 4s band becomes degenerate with the 3d band at VO and thus helps to destroy the Mott insulator state. The large difference in lattice constant between the metallic and insulating oxides is well accounted for in terms of the Mott transition.

Metal-insulator Transition in Transition Metal Oxides
IBM Journal of Research and Development, 1970The metal-insulator transition in the V2O3 system is discussed. A recent series of experiments on V2O3 and (V1-xCrx)2O3 is reviewed. The phase diagram fort he system is described. The Cr-doped mixed oxides are insulating at room temperature for x ≥ 0.009 and transform to a metal with the application of pressure. This phase transition is identified as a
