High Mechanical Properties of AZ91 Mg Alloy Processed by Equal Channel Angular Pressing and Rolling

Metals, 2019
Mechanical properties usually take precedence for wrought magnesium alloy when it would be used as a structure material. This paper proposed an approach that achieved high strength in AZ91 Mg alloy.

On the role of tail in stability and energetic cost of bird flapping flight

Scientific Reports, 2022
Migratory birds travel over impressively long distances. Consequently, they have to adopt flight regimes being both efficient—in order to spare their metabolic resources—and robust to perturbations.

Influence of Annealing treatment on Microstructure and Properties of Cold-drawn Al-3.0wt.%Mg Alloy

International Journal of Electrochemical Science, 2021
The influence of annealing treatment on the microstructure, mechanical properties and corrosion behavior of cold-drawn Al-3.0 wt%Mg alloy was investigated by 2D-XRD, microstructure observation, tensile test, immersion test and electrochemical measurement.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

From Mechanics to Machine Learning in Additive Manufacturing: A Review of Deformation, Fatigue, and Fracture

Technologies
Additive manufacturing (AM) enables a level of design flexibility that is difficult to achieve with conventional techniques, yet it inherently yields materials marked by significant variability, anisotropy, and sensitivity to defects that challenge ...

High temperature rise dominated cracking mechanisms in ultra-ductile and tough titanium alloy

Nature Communications, 2020
Specific titanium alloys combine transformation-induced plasticity and twinning-induced plasticity for improved work hardening. Here, the authors show that these alloys also have an ultra-large fracture resistance and an unexpected fracture mechanism via

Avalanches, loading and finite size effects in 2D amorphous plasticity: results from a finite element model [PDF]

, 2015
Crystalline plasticity is strongly interlinked with dislocation mechanics and nowadays is relatively well understood. Concepts and physical models of plastic deformation in amorphous materials on the other hand - where the concept of linear lattice ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
