An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.
