Jun 15, 2024 · Radium glass, a unique type of glassware, gained popularity in the late 19th and early 20th centuries, particularly during the Art Deco period. Its creation was facilitated by the discovery of radium by Marie and Pierre Curie in 1898, which sparked a fascination with radioactivity and its potential applications.
Jun 12, 2024 · Summary. Working with radium, which is highly radioactive, required the researchers to develop a process for synthesis and crystallization on a nanogram scale. Their success using this technique to characterize radium potentially allows scientists to learn exactly how radium binds to other elements—oxygen or nitrogen, for example.
