The chemistry of heavy metals changes under strong pressure: the discovery will help in working with nuclear and radioactive elements

The team found that the behavior of curium's outer electrons, which influence its ability to bind to

other elements, can be changed if the distance between it and the surrounding light atoms is reduced. 

However, only a few curium compounds showed such changes. Scientists are still interested in such processes: curium is usually completely resistant to changes in its properties.

This is a fascinating experiment and has shown that we have much more control over the chemical composition of these difficult to control elements than previously thought.

According to Albrecht-Schmitt, a deeperUnderstanding heavy elements opens the door to additional strategies for controlling chemical separation, which are used in the reprocessing of nuclear materials and in the development of resilient materials for long-term storage of radioactive elements. The research team believes that the results they achieved in the Curium experiment can be replicated with other heavy elements. 

In the future, the team plans to conduct similarexperiments for heavier elements such as californium and einsteinium, where the effect of pressure may be even greater than what they found in the case of curium.
