Dianium
Dianium was the proposed name for a new element found by the mineralogist and poet Wolfgang Franz von Kobell in 1860. The name derived from the Roman goddess Diana (mythology), Diana. During the analysis of the mineral tantalite and niobite he concluded that it does contain an element similar to niobium and tantalum. The symbol was Di. Following the rediscovery of niobium in 1846 by the German chemist Heinrich Rose, Friedrich Wöhler, Heinrich Rose, R. Hermann and Kobell analysed the minerals tantalite and columbite to better understand the chemistry of niobium and tantalum. The similar reactivity of niobium and tantalum hindered preparation of pure samples and therefore several new elements were proposed, which were later found to be mixtures of niobium and tantalum. Rose discovered pelopium in 1846, while Hermann announced the discovery of ilmenium in 1847. In 1860 Kobell published the results on the tantalite from a quarry near Kimito a village in Finland and columbite from Bod ...

Dénia
Dénia ( es, Denia) is a historical coastal city in the province of Alicante, Spain, on the Costa Blanca halfway between Alicante and Valencia, and the capital and judicial seat of the ''comarca'' of Marina Alta. Denia's historical heritage has been influenced by Iberian, Greek, Roman, Islamic, Napoleonic and Christian civilizations. , it had a population of 41,672, although this is more than doubled by tourism during the summer months. History There is evidence of human habitation in the area since prehistoric times and there are significant Iberian ruins on the hillsides nearby. In the 4th century BC it was a Greek colony of Marseille or Empúries, perhaps the one mentioned by Strabo as '' Hēmeroskopeion'' ( el, Ημεροσκοπείον) (meaning "watchtower"). It was an ally of Rome during the Punic Wars, and later was absorbed into the Roman Empire under the name of ''Dianium'' (after their goddess Diana). In the 1st century BC Quintus Sertorius established a Roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
