Government interventions can reduce deadly air pollution in South Asia, study finds
Air pollution, driven in large part by practices like crop burning, contributes to 2 million deaths a year in South Asia and persists as a public health emergency. But a new study co-led by Brown University researcher Gemma Dipoppa found that governm.....»»
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.....»»
