The power-conversion efficiencies (PCEs) of organic solar cells based on compounds known as polymer donors and fused ring electron acceptors (FREAs) have recently exceeded 19%. In contrast, organic solar cells based on non-fused ring electron acceptors (NFREAs), more...

The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort primarily relies on the analysis of data...

The hippocampus is a crucial region in the brain of mammals, which has been predominantly linked to the formation of memories. The retrieval of memories stored in the hippocampus at a later stage relies on a process known as “pattern separation,” which...

Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have been trying to leverage the spin angular momentum of electrons to...

Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed matter materials, including...
