This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
Following the first report that carbon monoxide is a normal neurotransmitter in 1993, [54] carbon monoxide has received significant clinical attention as a biological regulator. Because of carbon monoxide's role in the body, abnormalities in its metabolism have been linked to a variety of diseases, including neurodegenerations, hypertension ...
The first to utilize the electric spark to produce an explosion of hydrogen and oxygen, mixed in the proper proportions, to produce pure water. 1784: Henry Cavendish: Discovered the inductive capacity of dielectrics (insulators) and, as early as 1778, measured the specific inductive capacity for beeswax and other substances by comparison with ...
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Priestley did not exploit the commercial potential of carbonated water, but others such as J. J. Schweppe made fortunes from it. [83] For his discovery of carbonated water Priestley has been labelled "the father of the soft drink ", [ 84 ] with the beverage company Schweppes regarding him as "the father of our industry". [ 85 ]
Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear. The bond in a homonuclear diatomic molecule is non-polar. A periodic table showing the elements that exist as homonuclear diatomic molecules under typical laboratory conditions.
In addition to that, the hopcalite layer is protected by a mechanical filter and a layer of activated carbon, purify the air of other contaminants. [8] [9] [10] The operation of carbon monoxide (CO) detectors, on the other hand, is based on recording the heat released during the catalytic oxidation of carbon monoxide (CO) to carbon dioxide (CO 2).
2000 scientists at Fermilab announce the first direct evidence for the tau neutrino, the third kind of neutrino in particle physics. [30] 2000 CERN announced quark-gluon plasma, a new phase of matter. [34] 2001 the Sudbury Neutrino Observatory (Canada) confirm the existence of neutrino oscillations.
