Left dislocation in Zulu [PDF]

open access: yes, 2004
This paper examines left dislocation constructions in Zulu, a Southern Bantu language belonging to the Nguni group (Zone S 40). In Zulu left dislocation configurations, a topic phrase in the beginning of the sentence is linked to a resumptive element ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

First-principles calculations on dislocations in MgO

open access: yesScience and Technology of Advanced Materials
While ceramic materials are widely used in our society, their understanding of the plasticity is not fully understood. MgO is one of the prototypical ceramics, extensively investigated experimentally and theoretically. However, there is still controversy

Inhomogeneities in plastic deformation through dislocation glide

open access: yes, 1975
Recent research involving the direct computer simulation of plastic deformation through planar dislocation glide suggests that plastic inhomogeneities such as the formation and growth of discrete slip bands are an inherent feature of deformation through ...

Toward Single‐Crystal Upcycling of Degraded Lithium‐Ion Battery Cathodes

open access: yesEcoEnergy, EarlyView.
This review first summarizes the degradation mechanisms of polycrystalline cathodes, emphasizing the role of grain boundaries and rock‑salt phase formation. It then highlights the main optimization pathways (surface reconstruction, rapid structural repair, PC‑to‑SC transformation, and interface engineering) and the three conversion methods (SSU, MSAU ...

Quantifying nonlinear hydrogen–dislocation interactions in face-centered-cubic metals

open access: yesMaterials Research Letters
A three-dimensional nonlinear hydrogen-dislocation interaction framework for FCC metals is developed that captures the strong near-core coupling neglected by linear models.

Limited correlation between clinical failure and MRI graft status in the setting of revision anterior cruciate ligament reconstruction

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate whether clinically failed anterior cruciate ligament (ACL) reconstructions can be accurately identified using magnetic resonance imaging (MRI). Methods This prospective case series included 81 patients (mean age 33.5 ± 11.9 years, 50.6% male) with clinically failed ACL reconstructions defined by Lachman ≥ Grade 2, Pivot ...

Grain size, size-distribution and dislocation structure from diffraction peak profile analysis [PDF]

open access: yes, 2002
Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite ...

Decoupling the chemical-ordering-dependent dislocation and diffusion contributions to creep in multi-principal element alloy

open access: yesMaterials Research Letters
In multi-principal element alloys, dislocation motion and lattice diffusion are two key plasticity carriers, which are strongly interacted with the local chemical order.

Existence and stability of a screw dislocation under anti-plane deformation [PDF]

open access: yes, 2014
We formulate a variational model for a geometrically necessary screw dislocation in an anti-plane lattice model at zero temperature. Invariance of the energy functional under lattice symmetries renders the problem non-coercive.
