Researchers at EPFL have found a way to dramatically reducing energy loss and boosting efficiency perovskite solar cells by incorporating rubidium using lattice strain—a slight deformation in the atomic structure that helps keep rubidium in place.

Life needs sufficient phosphorus. However, the element is scarce, not only today but also at the time of the origin of life. So where was there sufficient phosphorus four billion years ago for life to emerge? A team of origin-of-life researchers has an answer.

At CERN, the European Organisation for Nuclear Research in Geneva, an international research team led by the Paul Scherrer Institute PSI has conducted especially precise measurements of atmospheric chemistry. Through this study the researchers were able to show how harmful particulate matter arises from vehicular emissions and biomass combustion. Their findings are helping to make existing models of particle formation more accurate.

New methods are making it possible to gain a more precise understanding of the role of organic molecules in the functioning of ecosystems. Researchers from Eawag and University of Zurich are therefore calling for a new “ecology of molecules”.

Polymer chemists at ETH Zurich have discovered a surprising way to virtually fully break down PMMA plastic – commonly known as Plexiglas – into its monomer building blocks. The process remains unaffected by the presence of additives.

Scientists at EPFL have revealed how quantum interference and symmetry dictate molecular behavior in collisions with gold surfaces, offering new insights into molecular interactions. The findings can have important implications for chemistry and materials science.
