New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy makers improve the accuracy of their decisions and allow timely interventions if needed. from Top Health News -- ScienceDaily https://ift.tt/3DvxDk4 via IFTTT
Organic photovoltaics have achieved remarkably high efficiencies, but finding optimum combinations of materials for high-performance organic solar cells, which are also economically competitive, still presents a challenge. Researchers from the United States and China have now developed an innovative interlayer material to improve device stability and electrode performance. In the journal Angewandte Chemie, the authors describe their fullerene-spiked, readily processable ionene polymer, which boosts the power conversion efficiency of organic solar cells.
