Eugène Soubeiran
Eugène Soubeiran (5 December 1797, in Paris – 17 November 1859, in Paris) was a French scientist. From 1823 he served as chief pharmacist at Pitié-Salpêtrière Hospital, La Pitie Hospital in Paris. In 1832 he became director of ''Pharmacie Centrale'', a drug manufacturing and distribution center for the hospitals and hospices of Paris (hôpitaux et hospices de Paris). The following year, he was chosen as an assistant professor of pharmacy, subsequently taking charge of the chair of physics at the ''Ecole de Pharmacie''. After receiving his medical degree, he was appointed to the chair of pharmacy at the Faculty of Medicine (1853). He was one of three researchers who discovered chloroform independently of one another. Soubeiran was the first to publish his findings, but it is difficult to determine who was actually first to make the discovery, as each may have allowed an interval of time to elapse between discovery and publication. In 1839, with Hyacinthe Capitaine, he was co- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Scientist
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...

Pharmacist
A pharmacist, also known as a chemist in English in the Commonwealth of Nations, Commonwealth English, is a healthcare professional who is knowledgeable about preparation, mechanism of action, clinical usage and legislation of medications in order to dispense them safely to the public and to provide consultancy services. A pharmacist also often serves as a primary care provider in the community and offers services, such as health screenings and immunizations. Pharmacists undergo university or graduate-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. In developing countries, a diploma course from approved colleges qualifies one for pharmacist role. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers. Among other licensing ...

Pitié-Salpêtrière Hospital
Pitié-Salpêtrière University Hospital (, ) is a charitable hospital in the 13th arrondissement of Paris. It is part of the AP-HP Sorbonne University Hospital Group and a teaching hospital of Sorbonne University. History The Salpêtrière was originally a gunpowder factory (saltpeter being a constituent of gunpowder), but in 1656 at the direction of Louis XIV, it was converted into a ''hospice'' for the poor women of Paris as part of the General Hospital of Paris. This main hospice was for women who were learning disabled, mentally ill, or epileptic, as well as poor. In 1657 it was incorporated with the hospice of the Pitié designed specifically for beggars' children and orphans. Sheets for hospice and military clothing were produced there by the children. Between 1663 and 1673, 240 of the women at the Pitié-Salpêtrière hospice were sent on a mission to populate the Americas and help build New France. They were in the total number of 768 young women recruited during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chloroform
Chloroform, or trichloromethane (often abbreviated as TCM), is an organochloride with the formula and a common solvent. It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and polytetrafluoroethylene (PTFE). Chloroform was once used as an inhalational anesthetic between the 19th century and the first half of the 20th century. It is miscible with many solvents but it is only very slightly soluble in water (only 8 g/L at 20°C). Structure and name The molecule adopts a tetrahedral molecular geometry with C3v symmetry. The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of ''terchloride'' (tertiary chloride, a trichloride) and ''formyle'', an obsolete name for the methylylidene radical (CH) derived from formic acid. Natural occurrence Many kinds of seaweed produce chlor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cubebin
''Piper cubeba'', cubeb or tailed pepper is a plant in genus ''Piper (plant), Piper'', cultivated for its fruit and essential oil. It is mostly grown in Java (island), Java and Sumatra, hence sometimes called Java pepper. The fruits are gathered before they are ripe, and carefully dried. Commercial cubeb consists of the dried berries, similar in appearance to black pepper, but with stalks attached – the "tails" in "tailed pepper". The dried pericarp is wrinkled, and its color ranges from grayish brown to black. The seed is hard, white and oily. The odor of cubeb is described as agreeable and aromatic and the taste as pungent, acrid, slightly bitter and persistent. It has been described as tasting like allspice, or like a cross between allspice and black pepper. Cubeb came to Europe via India through the trade with the Arabs. The name ''cubeb'' comes from Arabic language, Arabic ' () by way of Old French ''quibibes''. Cubeb is mentioned in alchemy, alchemical writings by ...

Cream Of Tartar
Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C4 H5 O6, is the potassium acid salt of tartaric acid (a carboxylic acid)—specifically, l-( + )-tartaric acid. Especially in cooking, it is also known as cream of tartar. It is produced as a byproduct of winemaking by purifying of the precipitate deposited by fermenting must in wine barrels, which arises from the tartaric acid and potassium naturally occurring in grapes. Approved by the FDA as a direct food substance, cream of tartar is used as an additive, stabilizer, pH control agent, antimicrobial agent, processing aid, and thickener in various food products. It is used as a component of baking powders and baking mixes, and is valued for its role in stabilizing egg whites, which enhances the volume and texture of meringues and soufflés. Its acidic properties prevent sugar syrups from crystallizing, aiding in the production of smooth confections such as candies and frostings. When combined ...

Boric Acid
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula . It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite. It is a weak acid that yields various borate anions and salt (chemistry), salts, and can react with Alcohol (chemistry), alcohols to form borate esters. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other boron compounds. The term "boric acid" is also used generically for any oxyacid of boron, such as metaboric acid and tetraboric acid . History Orthoboric acid was first prepared by Wilhelm Homberg (1652–1715) from borax, by the action of mineral acids, and was given the name ("sedative salt of Homberg"). However, boric acid and borates have been used since the time of the ancient Greece, anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Camphene
Camphene is a bicyclic organic compound. It is one of the most pervasive monoterpenes. As with other terpenes, it is insoluble in water, flammable, colorless, and has a pungent smell. It is a minor constituent of many essential oils such as turpentine, cypress oil, camphor oil, citronella oil, neroli, ginger oil, valerian, and mango. It is produced industrially by isomerization of the more common alpha-pinene using a solid acid catalyst such as titanium dioxide. Camphene is used in the preparation of fragrances and as a food additive for flavoring. These include isobornyl acetate. Biosynthesis Camphene is biosynthesized from linalyl pyrophosphate via a sequence of carbocation Carbocation is a general term for ions with a positively charged carbon atom. In the present-day definition given by the IUPAC, a carbocation is any even-electron cation with significant partial positive charge on a carbon atom. They are further ...ic intermediates. : References {{Authority ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
