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 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-discoverer of cubebin. Publi ...

Scientist
A scientist is a person who conducts Scientific method, scientific research 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 (circa 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. In modern times, many scientists have Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such ...

Pharmacist
A pharmacist, also known as a chemist (Commonwealth English) or a druggist (North American and, archaically, Commonwealth English), is a healthcare professional who prepares, controls and distributes medicines and provides advice and instructions on the correct and safe use of medicines to achieve maximum benefit, minimal side effects and to avoid drug interactions. They also serve as primary care providers in the community. 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. 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 requirements, different countries require pharmacists to hold either a Bachelor of Pharmacy, Master of Pharmacy, or Doctor of Pharmacy d ...

Pitié-Salpêtrière Hospital
Pitié-Salpêtrière University Hospital (french: Hôpital universitaire la Pitié-Salpêtrière, ) is a teaching hospital in the 13th arrondissement of Paris. Part of the and a teaching hospital of Sorbonne University. History The Salpêtrière was originally a gunpowder factory (saltpetre 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 th ...

Physics
Physics is the natural science that studies matter, its 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." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "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 physic ...

Chloroform
Chloroform, or trichloromethane, is an organic compound with chemical formula, formula Carbon, CHydrogen, HChlorine, Cl3 and a common organic solvent. It is a colorless, strong-smelling, dense liquid produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested. Structure The molecule adopts a tetrahedral molecular geometry with C3v symmetry group, symmetry. Natural occurrence The total global flux of chloroform through the environment is approximately tonnes per year, and about 90% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Abiotic processes are also believed to contribute to natural chloroform productions in soils although the mechanism is still unclear. Chloroform volatilizes readily from soil and surface water and undergoes degradation in ...

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 aroma, 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 writi ...

Cream Of Tartar
Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C4 H5 O6, is a byproduct of winemaking. In cooking, it is known as cream of tartar. It is processed from the potassium acid salt of tartaric acid (a carboxylic acid). The resulting powdery base can be used in baking or as a cleaning solution (when mixed with an acidic solution such as lemon juice or white vinegar). History Potassium bitartrate was first discovered by Swedish chemist Karl Wilhelm Scheele (1742-1786). This was a result of Scheele's work studying fluorite and hydrofluoric acid. Scheele may have been the first scientist to publish work on potassium bitartrate, but use of potassium bitartrate has been reported to date back 7000 years to an ancient village in northern Iran. Modern applications of cream of tartar started in 1768 after it gained popularity when the French started using it regularly in their cuisine. Occurrence Potassium bitartrate is naturally formed in grapes from th ...

Boric Acid
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula . It may also be called hydrogen borate 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 salts, and can react with 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 oxoacid 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 Greeks for cleaning, preserving food, and other activities. Molecular a ...

Camphene
Camphene is a bicyclic organic compound. It is one of the most pervasive monoterpenes. As for 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 A carbocation is an ion with a positively charged carbon atom. Among the simplest examples are the methenium , methanium and vinyl cations. Occasionally, carbocations that bear more than one positively charged carbon atom are also encountere ...ic intermediates.
