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 ...

Estimation of Wear Process of Grinding Wheels
Journal of the Japan Society of Precision Engineering, 1969 The wear process of grinding wheels is discussed by the following methods.1) The value of tan a is calculated by measuring the normal grinding force, where a is the half apical angle of the cone assumed to keep with ability of grain tips. On the basis of this result, the variation of the mean shape of grain tips is discussed.2) The profile curve of ...

Sustainable Development, EarlyView.ABSTRACT Isolating environmental issues from their broader social and political context limits understanding of their true drivers. In this sense, factors such as governance and education can be powerful determinants of environmental performance. This research examines the factors influencing the Environmental Health component of the Environmental ...

Small Methods, EarlyView.Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.
