A biography of ernest rutherford nobel prize winner in the science of chemistry
Mexican-born A biography of ernest rutherford nobel prize winner in the science of chemistry chemist known for his pivotal role in the discovery of the Antarctic ozone hole.
In 2004 Molina accepted the positions of professor at the University of California, San Diego and the Center for Atmospheric Sciences at the Scripps Institution of Oceanography. Molina is also Director of the Mario Molina Center for Energy and Environment in Mexico City. Molina is the son of Roberto Molina-Pasquel, a lawyer and judge who went on to serve as chief Ambassador to Ethiopia, Australia and the Philippines in 1923, and Leonor Henríquez. In 1974, as a postdoctoral researcher at University of California, Irvine, he and Rowland co-authored a paper in the journal Nature highlighting the threat of CFCs to the ozone layer in the stratosphere.
Rowland and Molina’s findings were disputed by commercial manufacturers and chemical industry groups, and a public consensus on the need for action only began to emerge in 1976 with the publication of a review of the science by the National Academy of Sciences. He also served on the board of directors of the John D. Molina was nominated to the Pontifical Academy of Sciences as of July 24, 2000. President Barack Obama to form a transition team on environmental issues in 2008.
Molina and his first wife, Luisa T. Luisa Tan Molina is the lead scientist of the Molina Center for Strategic Studies in Energy and the Environment in La Jolla, California. Mario Molina joined the lab of Professor F. Sherwood Rowland in 1973 as a postdoctoral fellow. Here, Molina continued Rowland’s pioneering research into «hot atom» chemistry, which is the study of chemical properties of atoms with, and only with, excess translational energy owing to radioactive processes.
CFCs were being released by human activity and were known to be accumulating in the atmosphere. Rowland and Molina had investigated compounds similar to CFCs before. Together they developed the CFC ozone depletion theory, by combining basic scientific knowledge about the chemistry of ozone, CFCs and atmospheric conditions with computer modelling. First Molina tried to figure out how CFCs could be decomposed.
At lower levels of the atmosphere, they were inert. Molina theorized that photons from ultraviolet light, known to break down oxygen molecules, could also break down CFCs, releasing a number of products including chlorine atoms into the stratosphere. ClO is also a radical, which reacts with ozone to A biography of ernest rutherford nobel prize winner in the science of chemistry two O2 molecules and a Cl atom. The radical Cl atom is not consumed in these reactions, so it remains in the system. Molina and Rowland predicted that chlorine atoms, produced by this decomposition of CFCs, would act as an ongoing catalyst for the destruction of ozone. When they calculated the amounts involved they realized that CFCs could start a seriously damaging chain reaction to the ozone layer in the stratosphere.

Rowland and Molina published their findings in Nature on June 28, 1974, and also made an effort to announce their findings outside of the scientific community, informing policy makers and the news media of their work. As a result of their work, laws were established to protect the ozone layer by regulating the use of CFCs. Miramontes co-inventor of the first oral contraceptive, ca. Mario Molina has received numerous awards and honors, including sharing the 1995 Nobel Prize in chemistry with Paul J. Molina was elected to the National Academy of Sciences in 1993.
Asteroid 9680 Molina is named in his honor. Mario Molina is a visionary chemist and environmental scientist. Molina came to America to pursue his graduate degree. He later earned the Nobel Prize in Chemistry for discovering how chlorofluorocarbons deplete the ozone layer. President’s Council of Advisors on Science and Technology.
