Diffusion bonding of high entropy alloy and stainless steel at a relative lower temperature via surface nano-crystallization treatment

open access: yesJournal of Materials Research and Technology, 2023
Sluggish diffusion effect of high entropy alloy limits its diffusion bonding with other components in practical applications. In this paper, the surface mechanical attrition treatment (SMAT) strategy for performing diffusion bonding joints of high ...

Effect of Post-Weld Heat Treatment on the Solid-State Diffusion Bonding of 6061 Aluminum Alloy

open access: yesApplied Sciences, 2021
The precipitation-hardenable aluminum alloy 6061 (AA 6061) is favored for aerospace components and automotive parts. However, the tenacious oxide layer on the surface greatly limits the quality and applicability of joining AA 6061.

Diffusion bonding of gold [PDF]

open access: yesGold Bulletin, 1998
Gold has a low modulus and does not form an oxide skin when heated in the air. Added to this is its rapid self-diffusion characteristic and these three properties together make this metal suitable for joining gold to gold. This paper presents a summary of a practical diffusion-bonding method for making such joints.

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

open access: yesFEBS 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 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Microstructural Evolution in Nonvacuum Solid-State Diffusion Bonded Joints of AA2219

open access: yesAdvances in Materials Science and Engineering, 2023
Solid-state diffusion bonding of AA2219 alloy is carried out under the nonvacuum condition to form AA2219/AA2219 joints. In the currently adopted method, AA2219 alloys are joined under the bonding temperature of 450–500°C, bonding pressure of 10 MPa, and
