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 ...

This article was originally published on The Conversation. Read the original article. Over Christmas vacation in 1938, physicists Lise Meitner and Otto Frisch received puzzling scientific news in a ...

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 ...

This article was originally published at The Conversation. The publication contributed the article to Live Science's Expert Voices: Op-Ed & Insights. Meitner and Frisch were able to provide an ...

The process of nuclear fission was first discovered in 1938; however, it wasn’t fully explained until a year later. Today – less than 100 years after its initial discovery – it is the poster child of ...

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 ...

Scientists have reviewed chemists' work on "singlet fission," a process in which a single photon generates a pair of excited states. This conversion process has the potential to boost solar cell ...

Singlet fission is a process whereby two triplet excitons can be produced from one photon, potentially increasing the efficiency of photovoltaic devices. Endothermic singlet fission is desired for a ...
