Robert Wilhelm Eberhard Bunsen (German: [ˈʁoːbɛʁt ˈbʊnzn̩]; 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 ]
Earth Day is on April 22, but really, it should be every day—saving the planet should be a daily occurrence! From conservation to wildlife to politics, test your environmental and historical ...
Robert Bunsen invented the now-famous Bunsen burner in 1855, which was useful in flame tests due to its non-luminous flame that did not disrupt the colors emitted by the test materials. [ 4 ] [ 1 ] The Bunsen burner , combined with a prism (filtering the color interference of contaminants ), led to the creation of the spectroscope , capable of ...
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 ...
The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", [1] and has since been awarded 140 times. [1] The medal is awarded annually and, unlike other Royal Society medals (such as the Hughes ), has been awarded without interruption since its inception.
There are plenty of reasons to look forward to spring. I, for one, am especially excited to celebrate warm-weather holidays like Easter, Mother’s Day and Cinco de Mayo (street-style tacos, FTW!).
The Bunsen–Kirchhoff Award is a prize for "outstanding achievements" in the field of analytical spectroscopy. It has been awarded since 1990 by the German Working Group for Applied Spectroscopy, and is endowed with €2500 by PerkinElmer, Germany. [1] [2] The prize is named in honor of chemist Robert Bunsen and physicist Gustav Kirchhoff.
