One hundred years after “nuclear isomers” were first discovered, Philip Walker and Zsolt Podolyák pick five examples of these long-lived, excited nuclear states to show why they are so important in ...

The thermodynamic stability of the vinylidene isomers, however, increases considerably when moving to the heavier elements of Group 14. Even upon formal replacement of the carbon scaffold by two ...

An international team of scientists trialled a new approach to passivating defects in perovskite solar cells. Using a tailored arrangement of atoms, the team was able to overcome challenges related to ...

In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered a new superheavy isotope, 257 Sg (seaborgium), whose properties are ...

Nobel laureate Otto Hahn is credited with the discovery of nuclear fission. Fission is one of the most important discoveries of the 20th century, yet Hahn considered something else to be his best ...

Bothtrans-N,N′-bis(2,2,6,6-tetramethyl-1-oxyl-4-piperidinyl)-1,2-diaminocyclopropane[Ro31-2269] and its cis isomer [Ro 31-2778] selectively sensitized hypoxic Chinese hamster cells, line V-79-753B, to ...
