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 ...

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...

Energy can never be created or destroyed. That's basic Physics 101. You simply cannot create energy out of thin air. Yet ...

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 ...

Japanese researchers developed a molybdenum-based spin-flip emitter that efficiently harvests triplet excitons from singlet-fission tetracene dimers, producing strong near-infrared emission. This ...

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 ...

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 ...

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 ...
