The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). [ 1 ] The process was invented in 1874 by Emil Wohlwill . This electrochemical process involves using a cast gold ingot , often called a doré bar , of 95%+ gold to serve as an anode . Lower perc... | https://en.wikipedia.org/wiki/Wohlwill_process |
The Wohl–Aue reaction is an organic reaction between an aromatic nitro compound and an aniline to form a phenazine in presence of an alkali base . [ 1 ] [ 2 ] An example is the reaction between nitrobenzene and aniline :
The reaction is named after Alfred Wohl and W. Aue. | https://en.wikipedia.org/wiki/Wohl–Aue_reaction |
The Wohl–Ziegler reaction [ 1 ] [ 2 ] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N -bromosuccinimide and a radical initiator . [ 3 ]
Best yields are achieved with N -bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [ 4 ] [ 5 ]... | https://en.wikipedia.org/wiki/Wohl–Ziegler_bromination |

In statistics , Wold's decomposition or the Wold representation theorem (not to be confused with the Wold theorem that is the discrete-time analog of the Wiener–Khinchin theorem ), named after Herman Wold , says that every covariance-stationary time series Y t {\displaystyle Y_{t}} can be written as the sum of two tim... | https://en.wikipedia.org/wiki/Wold's_theorem |
Woldemar Anatol Weyl (1901 – July 30, 1975) was a German-born scientist.
Weyl taught at the Kaiser Wilhelm Institute between 1932 and 1936, when he began traveling to the United States as a visiting professor at Pennsylvania State University . [ 1 ] Due to the increasing influence of the Nazi Party , Weyl choose not t... | https://en.wikipedia.org/wiki/Woldemar_Weyl |
Wolf distribution is the species distribution of the wolf ( Canis lupus ). Originally, wolves occurred in Eurasia above the 12th parallel north and in North America above the 15th parallel north . However, deliberate human persecution has reduced the species' range to about one-third, because of livestock predation and... | https://en.wikipedia.org/wiki/Wolf_distribution |
