شکل گریزان پلاس-4 تربیوم در شرایط آزمایشگاهی معمولی پدیدار می شود و امکانی را برای فلزات کمیاب خاکی ایجاد می کند.

Terbium's elusive plus-4 form emerges under ordinary lab conditions, opening possibilities for rare-earth metals

Chemists in a new study led by the University of Iowa report they have isolated and described in detail an atypical state of the rare-earth metal terbium, an advance that could expand its use in quantum technologies, including computing and advanced sensors. The study, "Structural and spectroscopic characterization of a Tb(IV) polyoxometalate," is published in the journal Nature Communications.
