Context. Particles in protoplanetary disks go through a number of phases that are dominated by collisions. In each of these events, grains exchange electrical charge via triboelectric effects. This enhances the stability of particle…
Small-angle coronagraphy is technically and scientifically appealing because it enables the use of smaller telescopes, allows covering wider wavelength ranges, and potentially increases the yield and completeness of circumstellar…
When inhaled nanoparticles (NPs) deposit in alveoli, they transit through the pulmonary surfactant (PS), a biofluid made of proteins and phospholipidic vesicles. They acquire a corona reflecting the PS-nanomaterials interaction. Since the…
