Influence of tool geometry on the formation of welded joint during friction stir welding of the AA5083 aluminum alloy

open access: yesFrontier Materials & Technologies
One of the important parameters influencing the formation of a weld during friction stir welding is the tool geometry, which affects the processes of heat generation and stirring of metals in their connection zone. These processes influence the formation

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

open access: yesPolymer 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 ...
