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 … WebApr 1, 2024 · Fusion. Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.
