Friedrich Stromeyer
Prof Friedrich Stromeyer FRS(For) FRSE (2 August 1776 – 18 August 1835) was a German chemist. He was the discoverer of cadmium. From 1982 a Friedrich Stromeyer Prize has been awarded for chemical achievement in Germany. Life He was born in Göttingen on 2 August 1776 the eldest son of Dr Ernerst Johann Friedrich Stromeyer, professor of medicine at Göttingen University, and his wife, Marie Magdalena Johanne von Blum. Stromeyer studied Chemistry and Medicine at Göttingen and Paris and received an MD degree from the University of Göttingen in 1800, studying under Johann Friedrich Gmelin and Louis Nicolas Vauquelin. He was then a professor at the university, and also served as an inspector of apothecaries. His students included Robert Bunsen. In 1817, whilst studying compounds of zinc carbonate, Stromeyer discovered the element cadmium . Cadmium is a common impurity of zinc compounds, though often found only in minute quantities. He was also the first to recommend starch as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General information The origins of Göttingen lay in a village called ''Gutingi, ''first mentioned in a document in 953 AD. The city was founded northwest of this village, between 1150 and 1200 AD, and adopted its name. In Middle Ages, medieval times the city was a member of the Hanseatic League and hence a wealthy town.

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light".

19th-century German Chemists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule.

François Sulpice Beudant
François Sulpice Beudant (5 September 1787 – 10 December 1850), was a French mineralogist and geologist. The mineral beudantite was named after him. Life He was born in Paris. He was educated at the Ecole Polytechnique and Ecole Normale, and in 1811 was appointed professor of mathematics at the lycée of Avignon. Thence he was called, in 1813, to the lycée of Marseilles to fill the post of professor of physics, where he carried out the first measurements of the speed of sound in seawater. In the following year the royal mineralogical cabinet was committed to his charge to be conveyed into England, and from that time his attention was directed principally towards geology and cognate sciences. In 1817 he published a paper on the phenomena of crystallization, treating especially of the variety of forms assumed by the same mineral substance. In 1818 he undertook, at the expense of the French government, a geological journey through Hungary, and the results of his researches ...

Edward Turner (chemist)
Edward Turner FRS FRSE FRCPE (24 June 1796 – 12 February 1837) was a Jamaican-born, British physician and chemist, known for his work on atomic weights, and as a populariser of the atomic theory of Dalton. He was the author of a popular chemistry textbook that was the first to incorporate chemical symbols and formulae as well as organic chemistry. Life He was born at Teak Pen in Clarendon, Jamaica, the eldest of nine children of Dutton Smith Turner (1755-1816) and Mary Gale Redwar (1776-1822), who were themselves children of Jamaican plantation owners. While he was young his parents relocated to Bath, where he received his early education at Bath Grammar School. Together with his younger brother, William Dutton Turner (28 June 1798 - June 1858), he attended the University of Edinburgh Medical School where they graduated M.D. in 1819 and 1820. William returned to Jamaica as a doctor in Spanish Town while Edward established a practice in Bath. After spending some time in ...

Royal Society Of Edinburgh
The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellows. The Society covers a broader selection of fields than the Royal Society of London, including literature and history. Fellowship includes people from a wide range of disciplines – science & technology, arts, humanities, medicine, social science, business, and public service. History At the start of the 18th century, Edinburgh's intellectual climate fostered many clubs and societies (see Scottish Enlightenment). Though there were several that treated the arts, sciences and medicine, the most prestigious was the Society for the Improvement of Medical Knowledge, commonly referred to as the Medical Society of Edinburgh, co-founded by the mathematician Colin Maclaurin in 1731.

Eudialyte
Eudialyte, whose name derives from the Greek phrase , , meaning "well decomposable", is a somewhat rare, nine member ring cyclosilicate mineral, which forms in alkaline igneous rocks, such as nepheline syenites. Its name alludes to its ready solubility in acid. Eudialyte was first described in 1819 for an occurrence in nepheline syenite of the Ilimaussaq intrusive complex of southwest Greenland. Uses of eudialyte Eudialyte is used as a minor ore of zirconium. Another use of eudialyte is as a minor gemstone, but this use is limited by its rarity, which is compounded by its poor crystal habit. These factors make eudialyte of primary interest as a collector's mineral. Eudialyte typically has a significant content of U, Pb, Nb, Ta, Zr, Hf, and rare earth elements (REE). Because of this, geoscientists use eudialyte as a geochronometer to date and investigate the genesis of the host rocks. Associated minerals Eudialyte is found associated with other alkalic igneous minerals, in addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bismuthate
Bismuthate is an ion. Its chemical formula is BiO3−. It has bismuth in its +5 oxidation state. It is a very strong oxidizing agent. It reacts with hot water to make bismuth(III) oxide and oxygen.
