Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
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 within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Framework helps autonomous drones rendezvous with sperm whales for better tracking
Project CETI (Cetacean Translation Initiative) aims to collect millions to billions of high-quality, highly contextualized vocalizations in order to understand how sperm whales communicate. But finding the whales and knowing where they will surface t.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
