Hace 3 días · The Swedish chemist Jöns Jakob Berzelius is credited with isolating zirconium in 1824. Until the 20th century, the metal could not be obtained in pure form, but in 1925 (100 years after the first samples of the element were isolated!) scientists finally succeeded in obtaining zirconium free of all impurities.
Hace 4 días · In 1839, Justus von Liebig, Friedrich Wöhler and Jöns Jacob Berzelius stated that yeast was not an organism and was produced when air acted on plant juice. In 1855, Antoine Béchamp, Professor of Chemistry at the University of Montpellier, conducted experiments with sucrose solutions and concluded that water was the factor for ...
The theory has been round for over a hundred years. It can be traced back to the work of Jöns Jacob Berzelius, Hermann Richter and Svante Arrhenius from 1830s to 1900. It has been enhanced over the years. Sky at Night. Unlike other theory which are nearly universally agreed, Panspermia has many distractors.
