Line-tension model for plasticity as the Gamma-limit of a nonlinear dislocation energy [PDF]

, 2012
In this paper we rigorously derive a line-tension model for plasticity as the Gamma-limit of a nonlinear mesoscopic dislocation energy, without resorting to the introduction of an ad hoc cut-off radius.

Void growth by dislocation adsorption

Materials Research Letters, 2020
We propose a dislocation adsorption-based mechanism for void growth in metals, wherein a void grows as dislocations from the bulk annihilate at its surface.

Decoupling Stable Cyclic Deformation From Defect Accumulation in Metals

Advanced Science, EarlyView.
Introducing amorphous nanoparticles into a metal matrix enables a cyclic deformation regime where strain hardening and defect accumulation are decoupled. These nanoparticles act as dislocation sinks and undergo reversible shear transformations, sustaining microstructural stability over millions of cycles.

Dislocation Glide in Ice Hi

, 1990
The field of geological materials is rapidly opening up to computer modelling and ice poses stimulating new problems. The normal pressure and 0°C form of ice is ice Ih in which the oxygen sublattice is wurtzite.

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Direct observation of misfit dislocation glide on surfaces

, 2001
Using scanning tunneling microscopy we have observed thermally induced dislocation glide in monolayer Cu films on Ru(0001) at room temperature. The motion is governed by a Peierls barrier that depends on the detailed structure of the dislocations, in ...

Musculoskeletal Phenotypes of 19 Patients With X‐Linked HNRNPH2‐Related Neurodevelopmental Disorder: A Prospective Case Series

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Detailed clinical phenotypes have been previously reported for 33 individuals with X‐linked HNRNPH2‐related neurodevelopmental disorder. Of these, 75% self‐reported a musculoskeletal abnormality, including hip dysplasia, scoliosis, kyphosis, lordosis, pes planus, arthritis, and missing spinous processes.
