4D printing of shape-programmable polymer-derived ceramics via two-stage folding-assisted pyrolysis strategy

open access: yesVirtual and Physical Prototyping
Polymer-derived ceramics (PDCs) can be used in wide applications due to their high hardness and stable chemical properties. However, these characteristics lead to the challenging controllable deformation of additively manufactured PDCs.

Grain structure control during metal 3D printing by high-intensity ultrasound

open access: yesNature Communications, 2020
3D printing of metals produces elongated columnar grains which are usually detrimental to component performance. Here, the authors combine ultrasound and 3D printing to promote equiaxed and refined microstructures in a titanium alloy and a nickel-based ...

Theoretical stiffness limits of 4D printed self-folding metamaterials

open access: yesCommunications Materials, 2022
The 3D stiffness of a self-folded metamaterial structure is limited by the low stiffness required by the folding process. Here, the stiffness limits of self-folding bilayers are theoretically established by a nonlinear model and experimentally validated ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
