Design a high-impact scientific journal cover focused on layered nickelates (Laₙ₊₁NiₙO₃ₙ₊₁). Central diagonal evolution from n=1 to n=∞ (La₂NiO₄ → La₃Ni₂O₇ → La₄Ni₃O₁₀ → LaNiO₃). Keep identical layered NiO₆ octahedral framework across all stages; only electron filling evolves (3d⁷ → 3d⁹). Show floating semi-transparent 3d orbitals and subtle energy-level splitting above the lattice, visualizing charge redistribution without structural change. Deep navy gradient background, soft cyan glow, slight magenta orbital accents, cinematic lighting, PBR, ultra-detailed 8K. No text, no labels, no QR code. Scientific, elegant, rational, non-sci-fi.
