Dubnium – Wikipedia
After extraction experiments of dubnium from hydrogen bromide into diisobutyl carbinol (2,6-dimethylheptan-4-ol), a specific extractant for protactinium, with subsequent elutions with the hydrogen chloride/hydrogen fluoride mix as well as hydrogen chloride, dubnium was found to be less prone to extraction than either protactinium or niobium. This was explained as an increasing tendency to form …

Le dubnium (d’après la ville de Doubna, en Russie) fut synthétisé pour la première fois en 1967 par l’ Institut unifié de recherches nucléaires (JINR), par l’équipe de Georgi Nikolaievitch Flerow, à Doubna 4. Fin avril 1970, une équipe de chercheurs dirigée par Albert Ghiorso de l’ université de Californie à Berkeley a confirmé cette découverte.

dubnium (Db), an artificially produced radioactive transuranium element in Group Vb of the periodic table, atomic number 105. The discovery of dubnium (element 105), like that of rutherfordium (element 104), has been a matter of dispute between Soviet and American scientists. The Soviets may have synthesized a few atoms of element 105 in 1967 at the Joint Institute for Nuclear Research in Dubna, Russia, U.S.S.R., by bombarding americium-243 with neon-22 ions, producing isotopes of element …

Dubnium Element | Uses, Facts, Physical & Chemical Characteristics
The LBL team bombarded a californium-249 target with nitrogen-145 ions and produced element 105 [1]. International Union of Pure and Applied Chemistry (IUPAC) confirmed the name dubnium in 1997 after the town Dubna where Joint Institute for Nuclear Research (JINR) was located [2]. The symbol of dubnium is Db.

Dubnium (Db) – Discovery, Occurrence, Production, Properties and …
Dubnium was first discovered in 1967 by scientists at the Joint Institute for Nuclear Research in Dubna while bombarding americium atoms with neon ions. In the same year, a team from the University of California bombarded californium atoms with nitrogen ions and obtained dubnium-260. However, the IUPAC assessed the claims of two groups in 1992 and concluded that the credit for the discovery of the element Dubnium should be shared by both the teams.

Dubnium is named for the town in Russia where it was first made, Dubna. It may only be produced in a nuclear facility. Dubnium does not exist naturally on Earth. The element dubnium was the subject of a naming controversy. The Russian discovery team (1969) proposed the name nielsbohrium (Ns) in honor of the Danish nuclear physicist Niels Bohr.
