Journal of Materials Research and Technology, 2023 High-content interstitial carbon addition has been proven to regulate the dislocation behavior in high-entropy alloys (HEAs) during deformation, thereby overcoming the strength-ductility trade-off, but its exact mechanism is still unclear.

Climb kinetics of dislocation loops in aluminium
Philosophical Magazine, 1968 Abstract The annealing kinetics of dislocation loops in quenched aluminium has been studied using transmission electron microscopy techniques. An influence of the vicinity of the foil surface on the rate of climb was confirmed. The apparent activation energy for climb of faulted loops was found to be 1·18 ± 0·02 ev and the pre-exponential factor, (7 ...

Phason Contribution to the Dislocation Loop Bias in Quasicrystals
, 2014 We develop a model of the absorption of vacancies and self-interstitial atoms by dislocation loops and associated phason defects in quasicrystals under irradiation. The capture efficiency and the bias of the loop for radiation point defects are evaluated

DISLOCATION DIPOLES AND DISLOCATION LOOPS
Le Journal de Physique Colloques, 1966 Basic theoretical ideas on the properties of two special dislocation configurations, dislocation dipoles and prismatic dislocation loops, are presented. Some of the author's recent results, based mostly on the application of the model of elastic continuum on these crystalline defects, are also given.

Cytosolic entry of Shiga-like toxin A chain from the yeast endoplasmic reticulum requires catalytically active Hrd1p [PDF]
, 2012 Background Escherichia coli Shiga-like toxin 1 normally traffics to the endoplasmic reticulum (ER) in sensitive mammalian cells from where the catalytic A chain (SLTxA1) dislocates to the cytosol to inactivate ribosomes.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dislocation Burgers vector and the Peach–Koehler force: a review
Journal of Materials Research and Technology, 2019 Different definitions of the Burgers vector and the corresponding construction of the Burgers circuit for dislocation loops and straight dislocations, created by the displacement discontinuity imposed across different surface cuts are reviewed.

FEBS Open Bio, EarlyView.KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

Molecular Dynamics Simulation on B3-GaN Thin Films under Nanoindentation
Nanomaterials, 2018 The B3-GaN thin film was investigated by performing large-scale molecular dynamics (MD) simulation of nanoindentation. Its plastic behavior and the corresponding mechanism were studied. Based on the analysis on indentation curve, dislocation density, and
