Radium chloride Radium chloride (RaCl) is a chemical compound of radium and chlorine, and the first radium compound isolated in a pure state. Marie Curie and André-Louis Debierne used it in their original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of this salt using a mercury cathode.

Marie Curie Marie Skłodowska Curie ( ; ] ; ] ; 7 November 18674 July 1934; born Maria Salomea Skłodowska; ] ) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, the only person to win a Nobel Prize in two different sciences, and was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.

Uranate A uranate is a ternary oxide involving the element uranium in one of the oxidation states +4, +5 or +6. A typical chemical formula is MUO, where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. The structures are infinite lattice structures with the uranium atoms linked by bridging oxygen atoms. "Ammonium diuranate" is an intermediate in the production of uranium oxide nuclear fuels.

Radium Girls The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint. Painting was done by women at three different sites in the United States, and the term now applies to the women working at the facilities. The first, United States Radium factory in Orange, New Jersey, beginning around 1917, at Ottawa, Illinois, beginning in the early 1920s, and a third facility in Waterbury, Connecticut.

Piperoxan Piperoxan, also known as benodaine, is a drug which was the very first antihistamine to be discovered. This compound, derived from benzodioxan, was prepared in the early 1930s by Daniel Bovet and Ernest Fourneau at the Pasteur Institute in France. Formerly investigated by Fourneau as an α-adrenergic-blocking agent, they demonstrated that it also antagonized histamine-induced bronchospasm in guinea pigs, and published their findings in 1933. Bovet went on to win the 1957 Nobel Prize in Physiology or Medicine for his contribution, and one of their students, Anne-Marie Staub, published the first structure-activity relationship (SAR) study of antihistamines in 1939.

George Radda Sir George Charles Radda (Hungarian: "György Károly Radda" ; born 9 June 1936) is a Hungarian chemist. In 1957 he attended Merton College, Oxford to study chemistry, having set aside an earlier interest in literary criticism. His early work was concerned with the development and use of fluorescent probes for the study of structure and function of membranes and enzymes. He became interested in using spectroscopic methods including nuclear magnetic resonance (NMR) to study complex biological material. In 1974, his research paper was the first to introduce the use of NMR to study tissue metabolites. In 1981, he and his colleagues published the first scientific report on the clinical application of his work. This resulted in the installation of a magnet large enough to accommodate the whole human body for NMR investigations in 1983 at the John Radcliffe Hospital in Oxford.

Ada Hitchins Ada Florence Remfry Hitchins (26 June 1891 – 4 January 1972) was the principal research assistant of British chemist Frederick Soddy, who won the Nobel prize in 1921 for work on radioactive elements and the theory of isotopes. Hitchins isolated samples from uranium ores, taking precise and accurate measurements of atomic mass that provided the first experimental evidence for the existence of different isotopes. She also helped to discover the element protactinium, which Dmitri Mendeleev had predicted should occur in the periodic table between uranium and thorium.

Gertrude Scharff Goldhaber Gertrude Scharff Goldhaber (July 14, 1911 – February 2, 1998) was a German-born Jewish-American nuclear physicist. She earned her PhD. from the University of Munich, and though her family suffered during The Holocaust, Gertrude was able to escape to London and later to the United States. Her research during World War II was classified, and not published until 1946. She and her husband, Maurice Goldhaber, spent most of their post-war careers at Brookhaven National Laboratory.

Barium borate Barium borate is an inorganic compound, a borate of barium with a chemical formula BaBO or Ba(BO). It is available as a hydrate or dehydrated form, as white powder or colorless crystals. The crystals exist in the high-temperature α phase and low-temperature β phase, abbreviated as BBO; both phases are birefringent, and BBO is a common nonlinear optical material.

Yttrium barium copper oxide Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds, famous for displaying high-temperature superconductivity. It includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen (77 K) at about 90 K. Many YBCO compounds have the general formula YBaCuO (also known as Y123), although materials with other Y:Ba:Cu ratios exist, such as YBaCuO (Y124) or YBaCuO (Y247).

Tetraborane Tetraborane (systematically named "arachno"-tetraborane(10)) was the first boron hydride compound to be classified by Stock and Messenez in 1912 and was first isolated by Alfred Hock. It has a relatively low boiling point at 18 °C and is a gas at room temperature. Tetraborane gas is foul smelling and toxic.

Friedrich Oskar Giesel Friedrich Oskar Giesel (20 May 1852 – 13 November 1927, known as Fritz) was a German organic chemist. During his work in a quinine factory in the late 1890s he started to work on the at-that-time-new field of radiochemistry and started the production of radium. In the period between 1902 and 1904 he was able to isolate a new element emanium. In a now controversially reviewed process it was stated that emanium is identical to actinium, which was discovered by André-Louis Debierne in 1899.
