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 ...

The discovery of nuclear fission in the 1930s brought with it first the threat of nuclear annihilation by nuclear weapons in the 1940s, followed by the promise of clean, plentiful power in the 1950s ...

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 ...

A team of scientists has provided new insights into the fission processes in exotic nuclei and for this, has produced the hitherto unknown nucleus mendelevium-244. The experiments were part of 'FAIR ...

In a breakthrough that could pave the way for more efficient and cleaner energy, researchers at Chalmers University of Technology in Sweden have discovered a rare phenomenon that changes what we know ...

Robert Adams updated the work on a phase 2 Pulsed Fission-Fusion (PuFF) Propulsion Concept. Robert works at the NASA Marshall Space Flight Center. This system should be able to achieve 15 kW/kg and 30 ...
