Abbreviation for New Brunswick, a Canadian province; nota bene (Latin “note well”), used in references and citations.

ETYM New Lat., from Latin and Eng. Niobe.
A soft gray ductile metallic element used in alloys; occurs in niobite; formerly called columbium; SYN. Nb, atomic number 41.
Soft, gray-white, somewhat ductile and malleable, metallic element, symbol Nb, atomic number 41, atomic weight 92.906. It occurs in nature with tantalum, which it resembles in chemical properties. It is used in making stainless steel and other alloys for jet engines and rockets and for making superconductor magnets.
Niobium was discovered in 1801 by English chemist Charles Hatchett (1765–1847), who named it columbium (symbol Cb), a name that is still used in metallurgy. In 1844 it was renamed after Niobe by German chemist Heinrich Rose (1795–1864) because of its similarity to tantalum (Niobe is the daughter of Tantalus in Greek mythology). + prikaži više
