Chloroform Is A chemical compound Known as trihalomethanes That Does not UNDERGO combustion in air, although it Will Burn When mixed With more flammable substances. Chloroform WAS Discovered first in July 1831 by American physician Samuel Guthrie, A Few Months Later Independently by French chemist Eugne Soubeiran And Then by German chemist Justus von Liebig.
1859 Discovery of petroleum jelly
Petroleum jelly, petrolatum or soft paraffin Is A semi-solid mixture of hydrocarbons Originally a topical ointment Promoted have healing properties for STIs. The raw material for petroleum jelly WAS Discovered in 1859 by Robert Chesebrough, a chemist from New York. In 1870, this product WAS Vaseline Petroleum Jelly have branded.
1873 Discovery of Chemical Potential
In thermodynamics, physics, and chemistry, chemical potential, symbolized by, Is A term Introduced by the American engineer, chemist, and mathematical physicist Josiah Gibbs In His 1873 paper A Method of Geometrical Representation of the Thermodynamic Properties of Substances by Means of Surfaces.
1877 Discovery of Deimos
Deimos Is The Small and outer of Mars Two Moons. It Was Discovered by Asaph Hall in 1877.
1877 Discovery of Phobos
Phobos Is The larger and closer of Mars' two small moons. It Was Discovered by Asaph Hall in 1877.
1891 Discovery of Amalthea
Amalthea Is The Third moon of Jupiter in order of distance from the Planet. It Was Discovered on September 9, 1892 by Edward Emerson Barnard.
1899 Discovery of Phoebe
Phoebe Is an irregular satellite of Saturn. It Was Discovered by William Henry Pickering on March 17, 1899 from photographic plates taken beens That HAD starting on August 16, 1898 at Arequipa, Peru by DeLisle Stewart.
1908 Discovery of Seyfert galaxies
Seyfert galaxies are a class of galaxies nuclei That Produce With spectral line emission from ionized gas Highly, named after Carl Keenan Seyfert, The Astronomer Who Identified The first class in 1943 although They Were Discovered first by Edward A. Fath in 1908 while He Was At The Lick Observatory.
1910 Discovery of propane
Propane Is A three-carbon alkane, Normally a gas, compressible object to a transportable liquid. It Is derived from petroleum products Other natural gas or oil Düring processing. It Is Commonly Used as a fuel for engines, barbecues, portable stoves and residential central heating. Propane WAS first Identified as a volatile component in gasoline by Dr. Walter O. Snelling of the U.S. Bureau of Mines in 1910.
1912 Discovery of the smoking-cancer link
Dr. Isaac Adler Was The First to Strongly Suggest That lung cancer related to smoking in IS 1912.
1914 Discovery of Sinope
Sinope Is A retrograde irregular satellite of Jupiter Discovered by Seth Barnes Nicholson at Lick Observatory in 1914.
1915 Discovery of the Zener diode
A Zener diode type of diode Is A That Permits In The current forward direction like a normal diode, to reverse direction aussi In The If The voltage IS Larger Than The Breakdown voltage Known as "Zener knee voltage" or "Zener voltage". The device WAS named after Clarence Zener Who Discovered this electrical property.
1916 Discovery of covalent bonding
The Idea of covalent bonding Can Be Traced SEVERAL Years to Gilbert N. Lewis, Who in 1916, rang The Sharing of electron peers Between atoms. He Introduced The So Called Lewis notation or electron dot notation or The Lewis Dot Structure in Which valence electrons as dots are Represented Around the atomic symbols.
1916 Discovery of heparin
Heparin, a highly-sulfated glycosaminoglycan, IS Widely Used As An injectable anticoagulant and has negative charge density The Highest of Any Known Biological molecule. It Can Be Used to form aussi year inner anticoagulant surface on Various experimental and medical devices Such as test tubes and renal dia.
