Ivan Stepanowitsch Plotnikow

from Wikipedia, the free encyclopedia

Ivan Stepanowitsch Plotnikow , Russian Иван Степанович Плотников , (born December 4, 1878 in Tambov , † July 31, 1955 in Zagreb ) was a Russian chemist who wrote textbooks on photochemistry .

In Germany he also published as Johannes Plotnikow.

Life

Plotnikow studied at Lomonossow University with a diploma in 1901 and received his doctorate in Leipzig under Wilhelm Ostwald in 1905 (reaction speeds at low temperatures) and was in Leipzig near Ostwald from 1901 to 1906 as an assistant. He was initially a laboratory assistant at the Laboratory for Organic and Analytical Chemistry of Nikolai Dmitrijewitsch Selinski at Lomonosov University. In 1908 he received his master's degree in chemistry. In 1909 he became a private lecturer with a course on experimental physical chemistry and in 1910 he was the first to teach photochemistry at Lomonosov University, where he also set up the first laboratory for photochemistry in Russia in 1913. His master's thesis Kinetics of Photochemical Reactions encountered resistance from part of the professorships ( Iwan Alexejewitsch Kablukow ), but received support from Selinski, Ostwald and Paul Walden . In 1912 he presented his later habilitation thesis (Russian doctoral thesis) (investigations of photochemical phenomena) and became an associate professor. The doctoral thesis also met resistance from some professors (Kablukow). In 1916 he became a full professor, but dismissed in 1917. He went to Berlin and, through Walter Nernst's mediation, headed Agfa's photochemical laboratory from 1919. In 1920 he became a professor at the Technical University in Zagreb, where he founded the chemistry department. In 1926 he founded the Institute of Physics and Technology at the University of Zagreb there.

He developed new types of devices for photochemical and thermochemical measurements, which promoted photochemical experimentation technology.

Plotnikov died in Zagreb, where he is also buried.
