École spéciale de Lausanne, 1857 Louis Rivier, founding member of École spéciale de Lausanne. The roots of modern-day EPFL can be traced back to the foundation of a private school under the name École spéciale de Lausanne in 1853 at the initiative of Lois Rivier, a graduate of the École Centrale Paris and John Gay, the then professor and rector of the Académie de Lausanne.
The condition that the ETH imposes on the diagonal elements of an observable is responsible for the equality of the predictions of the diagonal and microcanonical ensembles. [6] However, the equality of these long-time averages does not guarantee that the fluctuations in time around this average will be small.
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː-/ EE-) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum ...
A/D-corrin-ring closure by photochemical A/D-seco-corrin→corrin cycloisomerization, key step in the ETH Zurich A/D variant of the total synthesis of vitamin B 12 [3] In the early 1960s, having become Professor of General Organic Chemistry at ETH, Eschenmoser began work on what was the most complex natural product synthesized at the time ...
