Fukuoka, Japan—In organic molecules an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move ...

A five-dimensional model accurately predicts the asymmetric fission of mercury isotopes, advancing our understanding of nuclear fission beyond traditional heavy elements such as uranium and plutonium ...

Outdone only by nuclear fusion, the process of nuclear fission releases enormous amounts of energy. The ‘spicy rocks’ that are at the core of both natural and artificial fission reactors are generally ...

Lise Meitner, a brilliant physicist, was instrumental in understanding nuclear fission but was overlooked for the Nobel Prize ...

Add Yahoo as a preferred source to see more of our stories on Google. Although nuclear fission, which powers nuclear reactors, can provide plenty of energy, it also produces potentially dangerous ...

Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

A breakthrough this week in nuclear fusion could point the way to a future of carbon-free power. In a press conference Tuesday in California, the Department of Energy revealed that at 1:03 a.m. Dec. 5 ...

The elements above iron on the periodic table are thought to be created in cataclysmic explosions like the merger of two neutron stars or in rare classes of supernovae. New research suggests fission ...
