Suppressing σ phase formation by rapid solidification to prevent embrittlement in a low-cost aged medium-entropy alloy

Journal of Materials Research and Technology, 2023
Developing cost-effective high- and medium-entropy alloys (HEAs/MEAs) is essential to promote their broad industrial applications. A newly developed low-cost Fe45Cr25Ni10Mn15Al4C1 (at.%) MEA shows excellent compressive strength and ductility, but it is ...

Quantitative Description of Duplex Stainless Steels Microstructure Using Selective Etching

Metals, 2021
The properties of duplex stainless steels (DSSs) depend on the ferrite–austenite ratio, on the content of secondary phases and on the contamination with non-metallic inclusions. To assess the quality of DSSs, it is necessary to use an integrated approach

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
