Mario Molina, Mexican-born American chemist who won a share of the 1995 Nobel Prize for Chemistry for research in the 1970s concerning the decomposition of the ozonosphere , which shields Earth from dangerous solar radiation.
10/7/2020 · In 1974, Mario Molina and Sherwood Rowland demonstrated that CFC gases, freons, have a damaging effect on ozone in the atmosphere. Freons had many uses, including propellants in spray cans and refrigerants in refrigerators. By limiting the use of freons, the depletion of the ozone layer has been slowed.

Around 1985, after becoming aware of the discovery by Joseph Farman and his co-workers of the seasonal depletion of ozone over Antarctica, my research group at JPL investigated the peculiar chemistry which is promoted by polar stratospheric clouds, some of which consist of ice crystals.
Mario Molina is best known for his contribution towards the discovery of connection between CFCs and ozone depletion. It were through his efforts that several law enforcement bodies became aware of the harmful effects of these toxic industrial effluents, and legislation were laid out to prohibit the use of CFCs.
3/9/2019 · For his discoveries, Mario Molina shared the 1995 Nobel Prize in Chemistry with Rowland and Paul J. Crutzen (the scientist who popularized the term Anthropocene), one of the countless awards and honors he’s received in his illustrious career. He was also elected to the National Academy of Sciences in 1993, the United States Institute of Medicine in 1996, the.
José Mario Molina-Pasqual Henriquez was born and raised in Mexico City. From an early age, Mario was fascinated by the natural sciences. When he encountered his first microscope, he was thrilled to observe the organisms living in a drop of ordinary pond water.
