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

Virtual 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

Nature 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

Communications 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 ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A Cloud Manufacturing Application for Additive Manufacturing Methods

2019 IEEE International Conference on Mechatronics (ICM), 2019
Over the past years, the manufacturing industry has witnessed a great enhancement in the field of Additive Manufacturing that allows forming an inchoate market to produce custom-made products with low unit costs. At the same time, everyone may be a designer as well. However, the required equipment is only accessible for all the people.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
