Research
Zewail's key work has been as the pioneer of femtochemistry—i. Femtochemistry is the Science that studies Chemical reactions on extremely short timescales approximately 10–15 seconds (one Femtosecond e. the study of chemical reactions across femtoseconds. A chemical reaction is a process that always results in the interconversion of Chemical substances The substance or substances initially involved in a chemical reaction are called To help compare Orders of magnitude of different Times this page lists times between 10&minus15 second and 10&minus12 second (1 Femto Using a rapid ultrafast laser technique (consisting of ultrashort laser flashes), the technique allows the description of reactions on very short time scales - short enough to analyse transition states in selected chemical reactions. In Optics, an ultrashort pulse of light is an Electromagnetic pulse whose time duration is on the order of the femtosecond (10^{-15} second A laser is a device that emits Light ( Electromagnetic radiation) through a process called Stimulated emission. In Optics, an ultrashort pulse of light is an Electromagnetic pulse whose time duration is on the order of the femtosecond (10^{-15} second
In 1999, Zewail became the third ethnic Egyptian to receive the Nobel Prize, following Anwar Sadat (1978 in Peace) and Naguib Mahfouz (1988 in Literature).
