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] The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen ...
Rubidium chloride (RbCl) is probably the most used rubidium compound: among several other chlorides, it is used to induce living cells to take up DNA; it is also used as a biomarker, because in nature, it is found only in small quantities in living organisms and when present, replaces potassium.
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
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 ...

The first instrumental analysis was flame emissive spectrometry developed by Robert Bunsen and Gustav Kirchhoff who discovered rubidium (Rb) and caesium (Cs) in 1860. [4] Most of the major developments in analytical chemistry took place after 1900. During this period, instrumental analysis became progressively dominant in the field.
In Sanskrit, this plant is known by the name Manjishtha. It was used by hermits to dye their clothes saffron. It was used by hermits to dye their clothes saffron. Dioscorides and Pliny the Elder (De Re Natura) mention the plant (which the Romans called rubia passiva).
Boerhavia diffusa is a species of flowering plant in the four o'clock family which is commonly known as punarnava (meaning that which rejuvenates or renews the body in Ayurveda), [2] red spiderling, [1] spreading hogweed, [1] or tarvine. [1] It is taken in herbal medicine for pain relief and other uses.
