Tomsk Polytechnic University has received a registration certificate for the developed generators of the radioactive isotope technetium-99m as a medical device. Technetium is the most popular isotope ...

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 ...

Nuclear chemists and nuclear physicists at the University of Cologne provide experimental proof of a long-suspected atomic decay pathway. The article published in ‘Physical Review’ shows that ...

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 ...

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 ...

A SMALL quantity (0.11 gm.) of technetium-99 metal has recently been loaned to us by Oak Ridge Laboratories (U.S. Atomic Energy Commission) and we have taken the opportunity to measure the melting ...
