Publicación del 13 de octubre de 1995 La Jornada, México, D.F. Los Premios Nóbel de México A lo largo de los últimos 13 años, México ha logrado tres Premios Nóbel. El primero fue el de la Paz, concedido en 1982 al embajador Alfonso García Robles por sus múltiples gestiones diplomáticas en organismos internacionales en torno al desarme nuclear; en 1990, México celebraba el otorgamiento del Nóbel de Literatura al poeta Octavio Paz por su obra "apasionada, abierta sobre los vastos horizontes, impregnada de sensual inteligencia y de humanismo íntegro". Ahora, en 1995, el otorgamiento del Nóbel de Química a Mario Molina Henríquez, quien lo compartió con otros dos científicos, convierte al químico (nacido en México, pero nacionalizado estadounidense) en el primer mexicano y segundo hispanoamericano en ganar el galardón en ese género.

Nobelist to discuss ozone depletion at colloquium today Mario Molina, one of three atmospheric chemists to share the 1995 Nobel Prize, will deliver a chemistry colloquium on campus on April 4 at 4:40 p.m. in Room 200 Baker Lab. His lecture, "The Chemistry of Polar Ozone Depletion," is free and open to the public. It is sponsored by the Chemistry Department. Molina, professor of chemistry at the Massachusetts Institute of Technology, shared the Nobel Prize with Paul Crutzen of the Max Planck Institute for Chemistry and F. Sherwood Rowland of the University of California at Irvine for their pioneering work over more than two decades on the atmospheric effects of the chlorofluorocarbons (CFCs), which they showed to be responsible for the depeletion of stratospheric ozone. In 1974, Molina, then a postdoctoral fellow with Rowland at California, first described how chemically inert CFCs are wafted into the stratosphere where they are broken up by ultraviolet (UV) radiation in a process called photodissociation. Molina and Rowland closely calculated the mean atmospheric lifetimes of typical CFCs and deduced the catalytic role of the released chlorine atoms in the destruction of ozone molecules. In addition, Molina's investigations clearly outlined the threats posed by continuing use and production of industrial CFCs common in refrigerants and aerosol propellants threats which included a projected ozone depletion of 7 percent to 13 percent at the 1974 rate of production, accompanied by an increase in UV radiation. Use of CFCs as propellants was banned in the United States in 1978, and the three chemists were awarded the Nobel Prize on the eve of the 1996 ban of all ozone-depleting chemicals as mandated in the 1987 Montreal Protocol.

Mario J. Molina is a professor in the Departments of Planetary Sciences and Chemistry at the Massachusetts Institute of Technology. In 1995 he received the Nobel Prize in Chemistry for his work in atmospheric chemistry. He later joined the University of California at Irvine and began work on chlorofluorocarbons (CFCs). He and Professor Sherwood Rowland developed the CFC-ozone depletion theory. The ozone layer is important because it is a layer of gas around the planet earth that shields us from harmful ultraviolet rays. Dr. Molina was born in Mexico City, Mexico on March 19, 1943. His father was a lawyer and professor at the Universidad Nacional Autonoma de Mexico (University of Mexico) and later went on to serve as the Mexican Ambassador to Ethiopia, Australia and the Philippines. Molina remembers being intrigued by science while growing up in Mexico City and once converted a bathroom in his house into a chemistry laboratory. After studying chemical engineering at the Universidad Nacional Autonoma he eventually decided to pursue his doctorate in physical chemistry. Molina remembers this as one of his greatest challenges because he had to take classes that were not required of him in his earlier studies.

Mario J. Molina: B.S. Universidad Nacional Autonoma de Mexico 1965; Ph.D. University of California, Berkeley 1972. "Professor Molina's research interests lie in a field which is common to atmospheric chemistry and to chemical kinetics and photochemistry. The main objective of the research is the understanding of the potential implications of changes in the chemical composition of the earth's atmosphere: human activities are increasing the atmospheric concentrations of chlorofluorocarbons, methane, carbon dioxide and other gases on a global scale.

Nobel Prize Winning Chemists Mario Molina The Nobel Prize In Chemistry 1995 Mario Molina was born in Mexico City on March 19, 1943; his parents were Roberto Molina Pasquel and Leonor Henriquez de Molina. His father was a lawyer but he also taught at the National University of Mexico. He attended elementary school and high school in Mexico City. He was sent to a boarding school in Switzerland when he was 11 years old, on the assumption that German was an important language for a prospective chemist to learn. He had already decided at that time to become a research chemist. After finishing his undergraduate studies in Mexico, he decided to obtain a Ph. D. degree in physical chemistry. At first he went to Germany and enrolled at the University of Freiburg. After spending nearly two years doing research in kinetics of polymerizations, he realized that he wanted to have time to study various basic subjects in order to broaden his background and to explore other research areas. Finally, in 1968 he left for the University of California at Berkeley to pursue his graduate studies of physical chemistry. During his first year at Berkeley, he took courses in physics and mathematics, in addition to the required courses in physical chemistry. He then joined the research group of Professor George C. Pimentel, with the goal of studying molecular dynamics using chemical lasers. It was also at that time that he met Luisa Tan, who was a fellow graduate student in Pimentel's group and who later became his wife. His graduate work involved the investigation of the distribution of internal energy in the products of chemical and photochemical reations. His earliest achievement consisted of explaining some features in the laser signals as "relaxation oscillations," predictable from the fundamental equations of laser emission.

Mario Molina Mario Molina was born and raised in Mexico City, one of the most polluted cities in the world. Not surprisingly, today he is one of the world's most knowledgeable experts on pollution and on the effects of chemical pollution on the environment. Mario began his scientific career as a chemical engineering major in his native Mexico. Although he loved chemistry, he began to realize that there is a negative side to this field of science: Chemicals can be dangerous. He also discovered that research, rather than engineering, was his career goal. While working on his doctorate at the University of California at Berkeley, Mario began studying, along with his advisor Sherwood Roland, a particular type of chemical - chlorofluorocarbons - then widely used in consumer products. Mario wanted to know what happened to these chemicals when they entered the environment, because although they posed no danger to humans in their original form, these chemicals might change in the atmosphere. As Mario investigated chlorofluorocarbons, or CFCs, he realized that they were accumulating in the upper levels of the atmosphere. At high altitudes, the CFC molecules were breaking apart and the resulting chlorine atoms were destroying an important part of the atmosphere called ozone. Mario and Roland published their study about the ozone layer in the early 1970s, but no one seemed to react. After several years, the destruction of the ozone layer became big news. Mario became a spokesperson, calling for limits and controls on the production and use of CFCs. In 1984, scientists discovered a huge hole in the ozone layer over Antarctica. Still, some people did not believe that CFCs were the cause of the problem. However, Mario went back to his lab and proved how and why the chemical reaction was happening. After years of work, his research had been successful. In 1995, Molina was awarded the most prestigious award of all - the Nobel Prize for Chemistry.
