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.
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.
They consist of several to many flowers, found at both the ends of branches and in the leaf axils. The flowers appear from August to September, followed by small (4–6 mm diameter) red to black berries from October to November. [2] The roots can be over 1 m long, up to 12 mm thick. It prefers loamy soils with a constant level of moisture.
Various folk cultures and traditions assign symbolic meanings to plants. Although these are no longer commonly understood by populations that are increasingly divorced from their rural traditions, some meanings survive. In addition, these meanings are alluded to in older pictures, songs and writings.
Knowing what plants are poisonous to rabbits is key to keeping them safe and healthy. Rabbits are herbivores, meaning they only eat plants so it can be easy to think that anything green is safe ...
Adina cordifolia, synonym Haldina cordifolia, is a flowering plant in the family Rubiaceae. It is native to southern Asia, from India east to China and Vietnam and south to Peninsular Malaysia. [1] Adina cordifolia is a deciduous tree that can grow well over 20 metres high.
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).
