Google logo's Birthday Robert Bunsen

Google always uses different logos depending on the day of the moments that happen on certain days, such as Independence Day or other important day. Today, Google re-appear with the logo fit the observed moments of Robert Bunsen's 200th Birthday.

Who is Robert Bunsen? His full name is Robert Wilhelm Eberhard Bunsen (30 March 1811-16 August 1899) was a chemist Germany. He investigated emission spectra of heated elements, and with Gustav Kirchhoff discovered cesium (in 1860) and rubidium (in 1861). Bunsen developed installments of gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organoarsenic chemistry. With his laboratory assistant, Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use.
The Bunsen-Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.

Yes .. among the practitioners who deals in Chemistry Robert Bunsen definitely not a foreign name because every day in laboratoriu, when will heat up something, then we will use a device called the discovery of Robert Bunsen Bunsen burner or Bunsen Burner.




However, the contribution of Robert Wilhelm Eberhard Bunsen to expand knowledge rather than just the discovery that, he developed a number of common laboratory instruments, as well as new tools and processes to analyze the chemical elements, called Spectroscopy. His discovery of this one was developed with Gustav Kirchhoff, who is the most important legacy to science.

Bunsen received his doctorate in 1830 from the University of Göttingen, in his hometown. Because his performance with high value he received a grant from the Hanoverian government and with the funds that he wandered to Berlin, Bonn, Paris and Vienna for three years.

Profile of Robert Bunsen

Born in Göttingen, Germany, the youngest of four brothers, chief librarian, University of Göttingen and professor of modern philology, Christian Bunsen (1770-1837)

After finishing school in Holzminden, Bunsen in 1828 was accepted as a student at Göttingen and studied chemistry with Friedrich Stromeyer, and received his Ph.D. in 1831.

In 1832 and 1833 he traveled in Germany, France, and Austria, where he met Friedrich Runge (who discovered aniline and 1819 found the isolation of caffeine), Justus von Liebig at Giessen, and Eilhard Mitscherlich in Bonn.

In 1833, Bunsen became a lecturer at Göttingen and began experimental studies arsenous acid solubility of metal salts as would the discovery of iron oxide hydrate as an antidote against arsenic poisoning.

In 1836, Bunsen succeeded in cooperation with Friedrich Wöhler at Kassel Polytechnic School. Bunsen taught there for three years, as well as a lecturer at the University of Marburg, then continued his studies at cacodyl until promoted to full professor in 1841.

Bunsen almost died during the trial in cacodyl arsenic poisoning, and explosion hurt his right eye in the same year he found the Bunsen cell batteries, which use carbon electrodes rather than expensive platinum electrodes used in electrochemical cells William Robert Grove.

At the end of 1852 Bunsen became the successor of Leopold Gmelin at the University of Heidelberg. There he used electrolysis to produce pure metals such as chromium, magnesium, aluminum, manganese, sodium, calcium, barium, and lithium. Long collaboration with Henry Enfield Roscoe began in 1852, where they study the photochemical formation of hydrogen chloride from hydrogen and chlorine.

Bunsen decided to stop working with Roscoe in 1859 and joined Gustav Kirchhoff to study emission spectra of the elements is heated, the area of ​​research called spectrum analysis. For this work, Bunsen and laboratory assistant, Peter Desaga, has perfected a special gas burner by 1855, influenced by previous models. Newer design of Bunsen Desaga, which gives a very hot fire and clean his invention called the "Bunsen Burner"

In the summer of 1859, Bunsen Kirchhoff suggested to try to form a prismatic spectrum of colors. In October in the same year the two scientists have found an appropriate instrument, spectrometer prototype.

His invention is able to identify the characteristic spectrum of sodium, lithium, and potassium. Bunsen prove that any pure samples provide a unique spectrum. In this work, Bunsen succeeded in detecting the spectral emission of blue color in mineral water samples from Duerkheim, Germany. He suspected that these lines indicate the presence of a chemical element that has not been found. After distills forty tons of water, in the spring of 1860 he managed to isolate 17 grams of new elements. The so-called "cesium"

In 1860, he was elected as new members of the Royal Swedish Academy of Sciences. When Bunsen aged 78, retired from the field of geology and mineralogy, but the chase until the final verse. He died at Heidelberg at the age of 88
