Percy F. Frankland
Percy Faraday Frankland CBE FRS (3 October 1858 – 28 October 1946) was a British chemist. He was the second son and youngest child of Edward Frankland, chemist, and Sophie Fick, sister of Adolf Eugen Fick. He was born at 42 Park Road, Haverstock Hill, Hampstead, on 3 October 1858. Michael Faraday was his godfather. Frankland attended University College School from 1869-1874. The following year he was admitted to the Royal School of Mines, where he was taught by his father, Frederick Guthrie, T H Huxley, Judd and Warington Smyth Although he gained a Brackenbury scholarship to St Bartholomew's Hospital in 1878, and graduated with a BSc three years later, he was steered away from medicine to chemistry by his father. He studied for a PhD under Johannes Wislicenus at the University of Würzburg. Frankland returned to London in 1880, and became a demonstrator of practical chemistry at the Normal School of Science, South Kensington. Frankland left London in 1888 to become ...

Johannes Wislicenus
Johannes Wislicenus (; 24 June 18355 December 1902) was a German chemist, most famous for his work in early stereochemistry. Biography The son of the radical Protestant theologian Gustav Wislicenus, Johannes was born on 24 June 1835 in Kleineichstedt (now part of Querfurt, Saxony-Anhalt) in Prussian Saxony, and entered University of Halle-Wittenberg in 1853. In October 1853 he immigrated to the United States with his family. For a brief time he acted as assistant to Harvard chemist Eben Horsford, and in 1855 was appointed lecturer at the Mechanics' Institute in New York.

Chemical Society
The Chemical Society was a scientific society formed in 1841 (then named the Chemical Society of London) by 77 scientists as a result of increased interest in scientific matters. Chemist Robert Warington was the driving force behind its creation. The London Chemical Society 1824 The early days of the 1824 Chemical Society came with a rough start. Among the artisan class, the magazine ''The Chemist'', written by John Knight and Henry Lacey, had started to get some traction. Some argue that they falsely mentioned that the 1824 Chemical Society was attempting to gather an educated upper and middle-class group of chemists and philosophers. Because of this, the writers of ''The Chemist'' maintained a very practical and anti-theoretical bias, as they had lashed out at the time wasted by academic chemists researching atomic weight distributions. To find a means of how this society should be better set up and run, correspondents and proponents of ''The Chemist'' advised that membership i ...

Nitrification
''Nitrification'' is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms or entirely within one organism, as in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an aerobic process performed by small groups of autotrophic bacteria and archaea. Microbiology Ammonia oxidation The process of nitrification begins with the first stage of ammonia oxidation, where ammonia (NH3) or ammonium (NH4+) get converted into nitrite (NO2−). This first stage is sometimes known as nitritation. It is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). Ammonia-Oxidizing Bacteria Ammonia-Oxidizing Bacteria (AOB) are typically Gram-negative bacteria and belong to Betaproteobacteria and Gammaproteob ...

Grace Frankland
Grace Coleridge Frankland known as Mrs Percy Frankland ''née'' Grace Toynbee (4 December 1858 – 5 October 1946) was an English microbiologist. She was one of the nineteen female scientists who wrote the 1904 petition to the Chemical Society to request that they should create some female fellows of the society. Life She was the youngest of nine children; her parents were Harriet and Joseph Toynbee, a noted otologist. Two of her brothers were the economic historian Arnold Toynbee and the Dante scholar Paget Toynbee. She was home schooled and spent one year at Bedford College, She married Percy Frankland in 1882, and with him developed an interest in the emerging science of bacteriology. She worked with both Percy and his father Edward Frankland and was described at the time as having "worthily aided and seconded ercy. She co-authored papers with her husband on bacteria and other microorganisms found in the air and water. Colleagues of her husband noted that although their ...

Bacilli
Bacilli is a Taxonomy (biology), taxonomic Class (biology), class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as ''Bacillus anthracis'' (the cause of anthrax). ''Bacilli'' are almost exclusively gram-positive bacteria. The name ''Bacillus'', capitalized and Italics, italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. Ambiguity Several related concepts make use of similar words, and the ambiguity can create considerable confusion. The term "''Bacillus''" (capitalized and italicized) is also the name of a genus (''Bacillus anthracis'') that, among many other genera, falls within the cl ...

Stereochemistry
Stereochemistry, a subdiscipline of chemistry, studies the spatial arrangement of atoms that form the structure of molecules and their manipulation. The study of stereochemistry focuses on the relationships between stereoisomers, which are defined as having the same molecular formula and sequence of bonded atoms (constitution) but differing in the geometric positioning of the atoms in space. For this reason, it is also known as Three-dimensional space, 3D chemistry—the prefix "stereo-" means "three-dimensionality". Stereochemistry applies to all kinds of compounds and ions, Organic chemistry, organic and Inorganic chemistry, inorganic species alike. Stereochemistry affects Biochemistry, biological, Physical chemistry, physical, and supramolecular chemistry. Stereochemistry reactivity (chemistry), reactivity of the molecules in question (dynamic stereochemistry). History In 1815, Jean-Baptiste Biot's observation of optical activity marked the beginning of organic stereochemistr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Dundee
The University of Dundee is a public research university based in Dundee, Scotland. It was founded as a university college in 1881 with a donation from the prominent Baxter family of textile manufacturers.
