Dr. Mario Molina (1943-2020) |
Mario Molina was a Mexican chemist who is known for his groundbreaking research on the impact of human activities on the Earth's ozone layer. He was awarded the Nobel Prize in Chemistry in 1995 for his work on the atmospheric chemistry of ozone depletion.
Molina was born on 19 march 1943, in Mexico City.
Mario Molina's Education:- He completed his undergraduate studies at the National Autonomous University of Mexico (UNAM) and then went on to pursue a Ph.D. in physical chemistry at the University of California, Berkeley.
In the early 1970s, Mario Molina and his colleague, F. Sherwood Rowland, began investigating the chemistry of the Earth's atmosphere. They focused specifically on chlorofluorocarbons (CFCs), which were widely used as refrigerants and propellants in aerosol cans at the time.
How CFCs react with the ozone layer:- Through their research, Molina and Rowland discovered that CFCs could break down in the upper atmosphere and release chlorine atoms, which could then react with ozone molecules, leading to a depletion of the ozone layer. Mario Molina and his colleague, F. Sherwood Rowland's findings were published in the journal Nature in 1974.
Their research was met with skepticism at first, but as evidence of the harmful effects of CFCs continued to mount, governments around the world began to take action. The United Nations eventually adopted the Montreal Protocol in 1987, which called for a phasing out of CFCs and other ozone-depleting substances.
Molina continued to be an advocate for environmental protection throughout his career. He served on numerous advisory boards and was a member of the Intergovernmental Panel on Climate Change, which shared the Nobel Peace Prize in 2007.
In addition to his work on ozone depletion, Molina also conducted research on the atmospheric chemistry of air pollution and the potential impact of climate change on the Earth's ecosystems.
Molina passed away on October 7, 2020, at the age of 77. His legacy as a scientist and environmental advocate lives on, as his work continues to inspire and inform efforts to protect our planet.
Some interesting facts about Mario Molina:-
- Mario Molina was the first Mexican-born scientist to receive a Nobel Prize in the field of Chemistry.
