WebOct 14, 2024 · Singlet fission was first found in 1965 in anthracene and tetracene crystals [5,6,7,8] with a current resurgence of interest when pulsed optical spectroscopy enabled measurement of singlet fission on ultrafast timescales (≤100 fs) in solid-state pentacene with near-unity efficiency [].Singlet fission has since been observed in a wide range of … WebIn nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235 U). A nuclear chain reaction …
