Mario Molina is a Nobel Prize winning chemist from Mexico who co-developed the theory of ozone depletion due to CFCs
Mario J. Molina born at
Mario exchanged the nuptial vows with Luisa Y. Tan, who was a chemist herself in 1973 but the marriage culminated in divorce. The couple had a son named Felipe who is a practicing physician in Boston.
After separating from Luisa, he entered the wedlock with Guadalupe Álvarez, in 2006.
Mario J. Molina was the son of diplomat father Roberto Molina Pasquel and mother Leonor Henríquez. Born on March 19, 1943, Mario was close to his paternal aunt Esther Molina, whose profession had an ever-lasting impression on the young kid.
A curious kid, Molina displayed an inclination towards gaining knowledge in science at an early age. Esther helped him set up a laboratory in a sparsely used bathroom of their house, in New Mexico City, and encouraged him to observe things around him.
He received elementary education from schools in his native city and at the tender age of eleven attended the ‘Institut auf dem Rosenberg’ in Switzerland. It was customary in Molina’s family for kids to study abroad for a brief duration of time and Molina complied with the tradition.
After returning to Mexico, he pursued chemical engineering from the ‘National Autonomous University of Mexico’. He successfully completed his bachelor’s degree from the institute in the year 1965.
Following the completion of his undergraduate studies, the aspiring chemist pursued further studies from the ‘University of Freiburg’. At the institute he investigated the kinetic rates of polymerization reactions during his post graduation, which he completed in 1967.
He was inducted into the research group headed by member of faculty George C. Pimentel. Under the tutelage of the professor he applied chemical lasers to understand how internal energy was distributed in the products formed during several chemical and photochemical reactions.
He was awarded a doctoral degree in chemistry by the University of California in 1972. The following year he moved Irvine and assisted F. Sherwood Rowland in his research catering to chemistry of “hot atoms”.
During the course of experiments they conducted to understand the properties of atoms that were formed as a result of radioactive process and possessed excessive translational energy, Mario was assigned the task of studying inert chemicals emanated by industries and their atmospheric reactivity.
His research led him to the study of chlorofluorocarbons, which were major component of several industrial effluents released into the atmosphere. The duo of mentor and protégée observed that the CFCs once released showed very less chemical reactivity in the lower layers of atmosphere.
At higher altitudes, the CFC molecule disintegrates due to solar radiation and the resulting chlorine depletes the ozone by reacting with the atomic oxygen which forms the ozone. Thus a higher concentration of CFC in the atmosphere corrodes the protective ozone layer of the atmosphere.
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.
