fission

fissione nucleare

Divisione del nucleo di un atomo in parti più piccole, con liberazione di energia.

In inglese semplice: The splitting of the centre of an atom into smaller parts, releasing energy.

• Fission releases energy.
• The reactor uses nuclear fission to produce heat.
• Neutrons can trigger fission in uranium atoms.

Sinonimi: nuclear splitting

Contrari: fusion

Espressioni comuni: nuclear fission, fission reactor, fission products

scissione, divisione

Processo in cui una cosa si divide in due parti separate.

In inglese semplice: A process in which one thing divides into two separate things.

• Fission divided the group in two.
• The diagram shows fission into two separate parts.
• Repeated fission produced several independent groups.

Come si usa: fission into something (The study traced the group’s fission into two smaller communities.)

Sinonimi: splitting, division

Contrari: fusion

Espressioni comuni: fission into something, social fission

scissione binaria

Processo in cui un batterio si divide formando due nuove cellule.

In inglese semplice: A process in which a bacterium divides to make two new cells.

• These bacteria reproduce by fission.
• Binary fission creates two daughter cells.
• Warm conditions increased the rate of fission in the culture.

Sinonimi: cell division

Espressioni comuni: binary fission, fission in bacteria

scindere

Far dividere un atomo, una cellula o altro in parti più piccole.

In inglese semplice: To make an atom, cell, or other thing split into smaller parts.

• Neutrons can fission these nuclei.
• The experiment fissioned a small number of atoms.
• They used particles to fission the heavy nuclei.

Sinonimi: split, divide

Contrari: fuse

Espressioni comuni: fission uranium nuclei, fission an atom

scindersi

Dividersi in parti più piccole, come un atomo o una cellula.

In inglese semplice: To split into smaller parts, as an atom or cell does.

• Some nuclei fission spontaneously.
• The atoms fissioned after absorbing neutrons.
• These cells fission into two daughter cells.

Come si usa: fission into something (The nucleus can fission into two smaller nuclei.)

Sinonimi: split, divide

Contrari: fuse

Espressioni comuni: fission spontaneously, fission into something
