What did Madame Curie invent when she won the Nobel Prize in Physics for the first time and the Nobel Prize in Chemistry for the second time?

The Curies have been refining the radioactive components in pitchblende. After unremitting efforts, they finally succeeded in separating radium chloride and found two new chemical elements: polonium (po) and radium (lei). Due to the discovery and research of radioactivity, the Curies and henry beck Rael won the 1903 Nobel Prize in physics, and Madame Curie became the first woman to win the Nobel Prize in history. Eight years later, 19 1 1 year, Madame Curie won the Nobel Prize in chemistry for successfully separating radium. Unexpectedly, after winning the Nobel Prize, Madame Curie did not apply for a patent for the method of refining pure radium, but made it public, which effectively promoted the development of radiology.
