Nitric acid (aq) Layman's explanation: Nitric acid was first discovered in 1648 by a German chemist, Johann Rudolf. However, in 1901 Wilhelm Ostwald developed the Ostwald Process, which became the principle way of producing nitric acid.

- The 1979 Nobel prize was given to George Wittig for the development of this reaction, in which a carbonyl compound is turned into an olefin. This structure decomposes to Zwitterion (1) and a carbonyl compound (2), which can recombine to a normal ozonide (3). Ozone attack and tire sidewall protection. A carbonyl compound is reduced to an alcohol via a metal hydride.

- In order to send a text message to a phone via an email address, you'll need to know which carrier—e.g., Verizon, Sprint, T-Mobile, or AT&T—the phone uses. You sometimes can type the phone number into a computational search engine (e.g., WolframAlpha) to bring up information about the carrier.

- Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published.riestley, a big supporter of the phlogiston theory, called his discovery dephlogisticated air on the theory that it supported combustion so well because it had no phlogiston in it, and hence could absorb the maximum amount during burning.

- It all starts with a friendship between two men, plenty of natural curiosity and two kitchen stoves. Businessman Friedrich Bayer and dyer Johann Friedrich Weskott use these to conduct experiments and eventually discover how to make the dye fuchsine. On August 1, 1863, they found the Friedr. Bayer et. comp. company in Wuppertal-Barmen, a 19th century startup with tremendous potential.

Radioactive decay In the 19th century, Henri Becquerel discovered that some chemical elements have atoms that change: During their change they send out a particle. In 1898, Marie and Pierre Curie called this phenomenon radioactive decay. Becquerel and the Curies were awarded the Nobel Prize in Physics for this discovery, in 1903.

- Edward Turner was the first process to capture natural color on film stock. Beginning in 1932, Technicolor introduced a new color process— Process 4 , with one negative for each primary color and a matrix to improve contrast. This became the standard for the major Hollywood studios.his is a list of early color films from 1902 to around 1936 when the earliest films using the Technicolor three-strip process (Process 4) were released.

The Ostwald Process The Ostwald process is a chemical process that in two stages converts ammonia to nitric acid (also known as HNO3). Ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then nitrogen dioxide that was formed is absorbed in water, which forms nitric acid.

House Building Cost Per Square Foot Reinforced concrete continuous footings cost another $10 to $15 per linear foot. Add to this about $6 or $7 per line foot for a concrete block foundation wall. Supports in the center may be needed too, but to estimate figure $18 – $24 per linear foot of the parameter.For example if the foundation will be 24 x 30 foot, then you would multiple108 by $18 and then by $24.lab – A concrete slab will cost about $4 per square foot. So if a the slab is 24 x 30 foot, then your slab would cost $2880. This price varies though in different areas, and with the cost of concrete. Crawl Space – The cost is based on the perimeter of the home.

How the Manhattan Project Worked What Fermi had done, without recognizing it, was discover the process of nuclear fission. Two German scientists, Otto Hahn and Fritz Strassmann, were the first to officially acknowledge this process in 1938 when they successfully split uranium atoms into two or more parts.he interesting part about uranium, however, isn't so much the number of protons -- it's the unusually high number of neutrons in its isotopes. One isotope of uranium, uranium-235, has 143 neutrons and undergoes induced fission very easily.

- The process of nuclear fission was discovered in 1938 by Otto Hahn and Fritz Strassmann and was explained in early 1939 by Lise Meitner and Otto Frisch. The fissionable isotope of uranium, U-235, can be split by bombarding it with a slow, or thermal, neutron.

Ostwald process Ostwald process. The Ostwald process is a chemical process for making nitric acid (HNO3). Wilhelm Ostwald developed the process, and he patented it in 1902. The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production. Historically and practically, the Ostwald process is closely associated with the Haber process, which provides the requisite raw material, ammonia (NH3).

Werner syndrome He assumed the cause to be genetic, though most of his evidence was clinical. Between 1934 and 1941, two internists from New York, Oppenheimer and Kugel, coined the term Werner Syndrome, igniting a wave of interest and research on the disease.

- There is a scientific law called the Law of Conservation of Mass, discovered by Antoine Lavoisier in 1785. In its most compact form, it states: matter is neither created nor destroyed. In 1842, Julius Robert Mayer discovered the Law of Conservation of Energy. In its most compact form, it it now called the First Law of Thermodynamics: energy is neither created nor destroyed. In 1907 (I think), Albert Einstein announced his discovery of the equation E = mc 2 and, as a consequence, the two laws above were merged into the Law of Conservation of Mass-Energy: the total amount of mass and energy in the universe is constant.

He published, also in 1903, an independent description of the same disease described by Osgood. The disease is now known as Osgood-Schlatter's disease.

- Muller was a member of the research team at Columbia University that, under Thomas Hunt Morgan, developed the theory of chromosomal heredity from 1910 to 1915. Like his colleagues, Muller studied mutations and sought to map genes to specific chromosomes.
