WebAboutTranscript. Atomic and ionic radii are found by measuring the distances between atoms and ions in chemical compounds. On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron ... http://www.elch.chem.msu.ru/rus/spec/Vvedenie_v_spetsialnost_3/Hydrated_ions.pdf
Web19 mrt. 2024 · Rare earth nickel-based perovskite oxides (RENiO3) have been widely studied over recent decades because of their unique properties. In the synthesis of RENiO3 thin films, a lattice mismatch frequently exists between the substrates and the thin films, which may affect the optical properties of RENiO3. In this paper, the first-principles … Web1 okt. 2024 · Thus dopants La and Sm with larger ionic radii enhance the resistivity of the system compared to dopants Gd and Ho with smaller ionic radii. However, for Pr there is a sudden decrease in resistivity, likely because of the coexistence of the dual valence state of Pr ions (Pr 3+ and Pr 4+ ), as previously confirmed in the Rietveld analysis of the XRD …
