Transition metal-like carbocatalyst [PDF]
Nature Communications, 2020 AbstractCatalytic cleavage of strong bonds including hydrogen-hydrogen, carbon-oxygen, and carbon-hydrogen bonds is a highly desired yet challenging fundamental transformation for the production of chemicals and fuels. Transition metal-containing catalysts are employed, although accompanied with poor selectivity in hydrotreatment.

METAL-INSULATOR TRANSITIONS IN TRANSITION METAL OXIDES
Le Journal de Physique Colloques, 1971 There is a transition from band insulator to metal to Mott insulator with increasing number of d electrons in the transition metal oxides. In the (V1-xCrx)2O3 system a Mott transition occurs near x = 0.01. At high temperatures V2O3 and (V.99Cr.01)2 O3 are found to have similar resistivities and temperature coefficients of resistivity.

A P-type ATPase importer that discriminates between essential and toxic transition metals [PDF]
, 2009 Transition metals, although being essential cofactors in many physiological processes, are toxic at elevated concentrations. Among the membrane-embedded transport proteins that maintain appropriate intracellular levels of transition metals are ATP-driven
