Reversal in the Size Dependence of Grain Rotation

Physical Review Letters, 2017
The conventional belief, based on the Read-Shockley model for the grain rotation mechanism, has been that smaller grains rotate more under stress due to the motion of grain boundary dislocations. However, in our high-pressure synchrotron Laue x-ray microdiffraction experiments, 70 nm nickel particles are found to rotate more than any other grain size ...

In-situ study on the coordinated deformation mechanism of austenitic stainless steel with mixed crystal degree

Journal of Materials Research and Technology, 2023
A novel in-situ tensile experiment is designed to investigate the coordinated deformation mechanism between coarse grains (CGs) and fine grains (FGs) in the mixed crystal structure of X2CrNiMo18.12 austenitic stainless steel (X18.12).

Wheat (Triticum aestivum) production and grain quality resulting from compost application and rotation with faba bean

Journal of Agriculture and Food Research, 2022
Rotation with legumes and compost application are two possible approaches for improving soil fertility in sustainable wheat production. However, the efficiencies of different compost types may vary.

Crop yield and water use efficiency in response to long-term diversified crop rotations

Frontiers in Plant Science, 2022
Crop production and water productivity may be impacted by diverse crop rotation and management practices. A field study was conducted from 2017-2020 in the Loess Plateau to evaluate the effects of crop rotation sequences on pre-planting and post-harvest ...

A synergetic grain growth mechanism uniting nanograin rotation and grain boundary migration in nanocrystalline materials

Results in Physics, 2019
A theoretical model has been developed to analyze the energetic characteristic of a cooperative grain growth process in nanocrystalline materials. We proposed that the process can be realized by rotating the adjoining grains first and then migrating the ...

Alignment of suprathermally rotating grains [PDF]

Monthly Notices of the Royal Astronomical Society, 1995
It is shown, that mechanical alignment can be efficient for suprathermally rotating grains, provided that they drift with supersonic velocities. Such a drift should be widely spread due to both Alfvénic waves and ambipolar diffusion. Moreover, if suprathermal rotation is caused by grain interaction with a radiative flux, it is shown, that mechanical ...

Understanding dynamics in coarse-grained models. III. Roles of rotational motion and translation-rotation coupling in coarse-grained dynamics

The Journal of Chemical Physics, 2023
This paper series aims to establish a complete correspondence between fine-grained (FG) and coarse-grained (CG) dynamics by way of excess entropy scaling (introduced in Paper I). While Paper II successfully captured translational motions in CG systems using a hard sphere mapping, the absence of rotational motions in single-site CG models introduces ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.
