What if a material absorbed horizontally polarized light from the front, but vertically polarized light from the back? In Nature Materials, we show that this surprising behavior can emerge in common materials like colloidal nanoclusters. #NatureMaterials #Photonics doi.org/10.1038/s415...
Researchers have demonstrated a way to make large-scale chiral films from achiral semiconductors. The feat could pave the way for new antireflective coatings and noninvasive blood-sugar monitors.
Nonchiral Clusters Self-Assemble into Chiral Films
Researchers have demonstrated a method to create circular polarizing films from nonchiral nanoclusters that form spiral chains during drying.
