Kirchhoff and Bunsen discovered caesium and rubidium in 1861. In 1866, Christomanos brought the spectroscope to Greece and used the instrument on the island of Santorini to research the volcanic eruption of the Santorini caldera in 1866. [4] [5] Christomanos continued to restructure the chemistry department at the University. He brought ...
1860 was a leap year starting on Sunday of the Gregorian calendar and a leap year starting on Friday of the Julian calendar, the 1860th year of the Common Era (CE) and Anno Domini (AD) designations, the 860th year of the 2nd millennium, the 60th year of the 19th century, and the 1st year of the 1860s decade. As of the start of 1860, the ...
Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11] The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.

Spectroscope of Kirchhoff and Bunsen. The systematic attribution of spectra to chemical elements began in the 1860s with the work of German physicists Robert Bunsen and Gustav Kirchhoff, [30] who found that Fraunhofer lines correspond to emission spectral lines observed in laboratory light sources. This laid way for spectrochemical analysis in ...
UN maps are, in principle, open source material and you can use them in your work or for making your own map. UN requests however that you delete the UN name, logo and reference number upon any modification to the map. Content of your map will be your responsibility. You can state in your publication, if you wish, something like: based on UN ...
