Scientists spent years searching for Technetium, a chemical element that came, in time, to play a crucial role in medical diagnosis. So crucial in fact that a new search is already under way - to find ...

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...

When the periodic table was being put together in the late 1800s, a hole remained in the center of the middle row of transition metals where element 43 should be. This space stayed vacant until 1937, ...

Technetium is essential for medical imaging, yet supplies of this short-lived radioactive synthetic element are far from guaranteed. Show more Technetium is essential for medical imaging, yet supplies ...

A Nobel laureate, a comedian and a cast of chemists share their favourite elements, from a signature of alien life to a source of comic book superpower Technetium is the lightest radioactive element ...

Technetium carbide does not exist -- it was pure technetium that was mistakenly considered as such, say physicists. This is important from the view point of chemistry of transition metal carbides ...
