Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

Polymer Engineering &Science, EarlyView.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
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 ...

Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
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.
