Branca Edmée Marques
Branca Edmée Marques de Sousa Torres (Lisbon, 14 April 1899 - Lisbon, 19 July 1986) was a leading Portuguese specialist in the peaceful applications of nuclear technology who obtained a doctorate in Paris under the guidance of Marie Curie. Returning to Lisbon she founded the Radiochemistry Laboratory, where she continued her research for three decades. Career Marques' father died when she was just eight years old. After high school she joined the University of Lisbon. From there she graduated in Physics and Chemistry from the Faculty of Sciences. Having turned down a chance to do geological work in Angola, she taught at the faculty after her graduation in 1926, where she was the only woman carrying out teaching or research in chemistry. She married António Silva Sousa Torres (1876-1958), professor at the Faculty of Sciences of the University of Lisbon, but only on condition that she could go to Paris to study for a Doctorate. Wishing to specialize in radioactivity, she applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisbon
Lisbon ( ; ) is the capital and largest city of Portugal, with an estimated population of 567,131, as of 2023, within its administrative limits and 3,028,000 within the Lisbon Metropolitan Area, metropolis, as of 2025. Lisbon is mainland Europe's westernmost capital city (second overall after Reykjavík, Reykjavik), and the only one along the Atlantic coast, the others (Reykjavik and Dublin) being on islands. The city lies in the western portion of the Iberian Peninsula, on the northern shore of the River Tagus. The western portion of its metro area, the Portuguese Riviera, hosts the westernmost point of Continental Europe, culminating at Cabo da Roca. Lisbon is one of the List of oldest continuously inhabited cities, oldest cities in the world and the second-oldest European capital city (after Athens), predating other modern European capitals by centuries. Settled by pre-Celtic tribes and later founded and civilized by the Phoenicians, Julius Caesar made it a municipium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbonne University
Sorbonne University () is a public research university located in Paris, France. The institution's legacy reaches back to the Middle Ages in 1257 when Sorbonne College was established by Robert de Sorbon as a constituent college of the University of Paris, one of the first universities in Europe. Its current iteration was formed in 2018 by the merger of Paris-Sorbonne University (Paris IV) and the Université Pierre et Marie Curie (Paris VI). Sorbonne University is one of the most sought after universities by students and researchers from France, Europe, and the French speaking countries. Most notably, Marie Skłodowska-Curie, who came from Poland in 1891 and joined the Faculty of Sciences of the University of Paris, was also the first woman to become a professor at the Sorbonne. Marie Curie and her husband Pierre Curie are considered the founders of the modern-day Faculty of Science and Engineering of Sorbonne University. As of 2021, its alumni and professors have won 33 ...

Radioactivity
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered ''radioactive''. Three of the most common types of decay are Alpha decay, alpha, Beta decay, beta, and Gamma ray, gamma decay. The weak force is the Fundamental interactions, mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic force, electromagnetic and nuclear forces. Radioactive decay is a randomness, random process at the level of single atoms. According to quantum mechanics, quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as a half-life. The half-lives of radioactive atoms have a huge range: f ...

Comptes Rendus De L'Académie Des Sciences
(, ''Proceedings of the Academy of Sciences''), or simply ''Comptes rendus'', is a French scientific journal published since 1835. It is the proceedings of the French Academy of Sciences. It is currently split into seven sections, published on behalf of the Academy until 2020 by Elsevier: ''Mathématique, Mécanique, Physique, Géoscience, Palévol, Chimie, ''and'' Biologies.'' As of 2020, the ''Comptes Rendus'' journals are published by the Academy with a diamond open access model. Naming history The journal has had several name changes and splits over the years. 1835–1965 ''Comptes rendus'' was initially established in 1835 as ''Comptes rendus hebdomadaires des séances de l'Académie des Sciences''. It began as an alternative publication pathway for more prompt publication than the ''Mémoires de l'Académie des Sciences,'' which had been published since 1666. The ''Mémoires,'' which continued to be published alongside the ''Comptes rendus'' throughout the ninetee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frédéric Joliot-Curie
Jean Frédéric Joliot-Curie (; ; 19 March 1900 – 14 August 1958) was a French chemist and physicist who received the 1935 Nobel Prize in Chemistry with his wife, Irène Joliot-Curie, for their discovery of induced radioactivity. They were the second married couple, after his parents-in-law, to win the Nobel Prize, adding to the Curie family legacy of five Nobel Prizes. Joliot-Curie and his wife also founded the Orsay Faculty of Sciences, part of the Paris-Saclay University. Biography Early years Born in Paris, France, Frédéric Joliot was a graduate of ESPCI Paris. In 1925 he became an assistant to Marie Curie, at the Radium Institute. He fell in love with her daughter Irène Curie, and soon after their marriage in 1926 they both changed their surnames to Joliot-Curie. At the insistence of Marie, Joliot-Curie obtained a second baccalauréat, a bachelor's degree, and a doctorate in science, doing his thesis on the electrochemistry of radio-elements. Career W ...
