Atomistic mechanism of phase transformation between topologically close-packed complex intermetallics

open access: yesNature Communications, 2022
It is challenging to study how topologically close-packed phases (TCPs) transform between one phase to another. Here the authors use atomic-resolved tools to look at the transformation between μ and P phases, revealing an intrinsic link between seemingly

Mechanical Properties [PDF]

open access: yes, 2018
This chapter report the most recent experimental results on mechanical behaviour at high temperature of high-performance concretes. After a short introduction, Sect. 5.2 describes the main testing methods that were used in the analysed studies. Section 5.3 collects and compares the temperature-dependency of the compressive strength and modulus of ...

Misfit strain-induced mechanical cracking aggravating surface degradation of LiCoO2

open access: yesMaterials Research Letters, 2023
Cycling-induced cathode interfacial degradations are usually attributed to chemical process, while the physical effect is overlooked to a large extent. Herein, we investigate the failure mechanism of LiCoO2 cathode and reveal that misfit strain plays a ...

Quantitative Investigation of the Link between Actin Cytoskeleton Dynamics and Cellular Behavior

open access: yesMicromachines, 2022
Actin cytoskeleton reorganization, which is governed by actin-associated proteins, has a close relationship with the change of cell biological behavior. However, a perceived understanding of how actin mechanical property links to cell biological property

New twinning route in face-centered cubic nanocrystalline metals

open access: yesNature Communications, 2017
Twin nucleation in face-centered cubic metals with high twin-fault energies should theoretically be unfavourable, but instead twinning is very often observed.
