Significats de actinide en anglès

Whereas this chemistry is intensively explored for transition-metal and lanthanide ions, any related actinide compound has not received attention.

And if you pack together enough of certain actinide atoms, their nuclei will erupt in a powerful release of energy.

Radioactive doses to local seafood consumers have been rising steeply since BNFL commissioned a new, enhanced actinide removal plant in 1994.

Evaluating the nature of chemical bonding for actinide elements represents one of the most important and long-standing problems in actinide science.

A group of rats were given a single injection of 237Np-nitrate solution in order to observe the acute toxicity effects of this actinide.

It is composed of discrete actinide centers in ten-fold coordination, with 8 carboxyl oxygen atoms and 2 oxygen atoms from DMF molecules.

For both actinides, like-for-like An-O → An-N substitutions lead to improved reaction energies.

Actinides are dense because their nuclei contain large numbers of neutrons and protons.

But it's the strange behavior of those nuclei that has long made actinides the stuff of wonder.

Actinides are the only materials that split apart this way, and if the collisions are uncontrolled, you unleash hell: a nuclear explosion.

At intervals that can vary from every millisecond to every hundred thousand years, actinides spin off particles and decay into more stable elements.
