Material properties and osteoporosis [PDF]

F1000Research, 2019
The main clinical tool for the diagnosis and treatment of skeletal diseases such as osteoporosis is the determination of bone mineral density by dual x-ray absorptiometry. Although this outcome contributes to the determination of bone strength, the clinical evidence to date suggests that it does not correlate strongly with fracture incidence.

Growth competition between columnar dendrite and degenerate seaweed during directional solidification of alloys: Insights from multi-phase field simulations

Materials & Design, 2020
In this paper, the growth competition between columnar dendrite and degenerate seaweed during directional solidification of a dilute alloy was investigated by using the quantitative multi-phase field model of dilute binary alloys developed by Ofori-Opoku

Ultra-large elongation and dislocation behavior of nano-sized tantalum single crystals

AIP Advances, 2017
Although extensive simulations and experimental investigations have been carried out, the plastic deformation mechanism of body-centered-cubic (BCC) metals is still unclear. With our home-made device, the in situ tensile tests of single crystal tantalum (

Twin thickness and dislocation interactions affect the incoherent-twin boundary phase in face-centered cubic metals

Cell Reports Physical Science, 2022
Summary: Incoherent-twin boundaries (ITBs) can significantly affect the mechanical properties exhibited by metals. Although numerous studies have been conducted to date, the atomic structures of such ITBs remain unclear, owing to difficulties in imaging ...

In situ atomic-scale observation of grain size and twin thickness effect limit in twin-structural nanocrystalline platinum

Nature Communications, 2020
The deformation mechanisms of micron-sized twinned metals are well-understood, but it is not so for twinned nanocrystalline metals. Here, the authors use high resolution microscopy to image the deformation of nanocrystalline twinned platinum and show ...
