High strain rate characterization of ZEK100 magnesium rolled alloy sheet

EPJ Web of Conferences, 2012
In this paper, the constitutive behaviour of a rare-earth magnesium alloy ZEK100 sheet is studied at room temperature and over a wide range of strain rates.

Twin recrystallization mechanisms in a high strain rate compressed Mg-Zn alloy

Journal of Magnesium and Alloys, 2021
Static recrystallization of a high strain rate compressed Mg-1 Zn (wt.%) alloy was investigated using electron backscattered diffraction (EBSD). A novel 53°〈101¯0〉 structure was observed in the as-deformed alloy, which showed a {101¯2}-{101¯2} double ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS 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.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Physical nature of strain rate sensitivity of metals and alloys at high strain rates [PDF]

Journal of Physics: Conference Series, 2018
The role of instabilities of plastic flow at plastic deformation of various materials is one of the important cross-disciplinary problems which is equally important in physics, mechanics and material science. The strain rate sensitivities under slow and high strain rate conditions of loading have different physical nature.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

A method to calibrate a specimen with strain gauges to measure force over the full-force range in high rate testing [PDF]

, 2009
This paper investigates a new method to calibrate a tensile specimen with strain gauges to measure force over the full range of loading at intermediate strain rate for use in high rate testing.

High strain-rate response of additively manufactured light metal alloys

Materials & Design, 2022
Understanding the high strain-rate response of materials is essential in applications including aerospace, automotive, and defence. Structures of these applications are often subjected to dynamic loadings of high strain rates and need to mitigate the ...
