An unexpected discovery in Professor Arthur Suits’ chemistry lab could have implications for manufacturing more efficient solar cells and improving photodynamic therapies for treating cancer, and it may contribute to research into quantum computing. At the heart of the discovery is the spin of electrons. Molecules are either nonmagnetic or magnetic depending on whether two electrons are paired with opposite spins or unpaired with same spins. Molecules can switch from magnetic to nonmagnetic forms or vice versa in a process called flipping a spin, but Suits says that process is inefficient and happens slowly.
