In 1896, Henri Becquerel encouraged her to study how radiations emitted by uranium salts, which had been discovered by him. Together with her husband, Marie began to study the materials that produce such radiations, looking for new elements which, according to a hypothesis that the two defenders, should exist in certain ores as a pitchblende (which had a curious characteristic of emitting still More radiation than the uranium extracted from it). Indeed, in 1898 they deduced that there would certainly be in the pitchblende some component releasing more energy than uranium; On December 26, the same year, Maria Skłodowska Curie announced a discovery of this new substance to the Academy of Sciences of Paris.
After several years of constant work, through the concentration of several classes of pitchblende, they isolated two new chemical elements. The first was named polonium, in reference to its native country, and the other radio, due to its intense radiation, obtained 0.1 g in 1902. Subsequently part of all the tons of pitchblende, obtained another 1 g of radio. . Proposition, have never patented the process and development. The radioactive terms and radioactivity were invented by the couple to characterize an energy released spontaneously by this new chemical element.
With Pierre Curie and Antoine Henri Becquerel, Marie-Novella of the Nobel Prize in Physics of 1903, "in recognition of the extraordinary results obtained by their joint investigations on the phenomena of radiation, discovered by Henri Becquerel." She was the first woman to receive such a prize.
Marie Curie got her husband, Pierre Curie, to become head of the Sorbonne Physics Laboratory. She graduated in science in 1903, and after Pierre Curie's death in 1906, in a road accident, she took her place as a professor of General Physics at the Faculty of Sciences. She was the first woman in charge of this charge. She was also appointed Director of the Curie Laboratory of the Radium Institute, University of Paris, founded in 1914.
Marie Curie also had a significant role as an educator. As early as 1885, at the age of 18, she pursued a profession of private teacher for children of families in Poland.
Eight years later, he was awarded the Nobel Prize in Chemistry in 1911, in recognition of his services for the advancement of chemistry, the discovery of radio and polonium elements, the isolation of radio and the study of the nature of the compounds of this element. With a generous attitude, he did not patent the process of isolation of the radio, allowing the investigation of the properties of this element throughout the scientific community.
She was the first person to receive twice the Nobel Prize. Linus Pauling repeated the feat, winning the Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962 and became the only personality to have received two non-shared Nobel Prizes. On the other hand, Marie Curie was the only person to receive twice the Nobel Prize, in distinct scientific areas.
During World War I, Curie proposed the use of mobile radiography for the treatment of wounded soldiers. In 1921 he visited the United States, where he was received triumphantly. The reason for the trip was to raise funds for research. In her later years she was harassed by many physicists and cosmetics producers, who made use of radioactive material without precautions. He also visited Brazil, attracted by the fame of the radioactive waters of Lindóia, today known by the name of Waters of Lindóia.
He founded the Radio Institute in Paris. In 1922 he became a free associate member of the Academy of Medicine.
