60 years of dislocations in ceramics: A conceptual framework for dislocation mechanics in ceramics
International Journal of Ceramic Engineering & Science, 2022 High‐tech ceramics are typically engineered by controlling point defects and interfaces while one‐dimensional dislocations have found much less attention so far.

Dislocations in uniaxial lamellar phases of liquid crystals, polymers and amphiphilic systems
, 1995 Dislocations in soft condensed matter systems such as lamellar systems of polymers, liquid crystals and ternary mixtures of oil, water and surfactant (amphiphilic systems) are described in the framework of continuum elastic theory.

Topological dragging of solitons
, 2005 We put forward properties of solitons supported by optical lattices featuring topological dislocations, and show that solitons experience attractive and repulsive forces around the dislocations.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The study of plastic deformation in the crack surrounding in AZ61 alloy [PDF]
FME Transactions, 2013 This paper deals with the study of effect of microstructure on the development of plastic deformation around the propagating cracks of the magnesium alloy whose corrosion resistance is increased by the addition of 0.5 wt. % Ca.

Nonequilibrium dislocation dynamics and instability of driven vortex lattices in two dimensions
, 2000 We consider dislocations in a vortex lattice that is driven in a two-dimensional superconductor with random impurities. The structure and dynamics of dislocations is studied in this genuine nonequilibrium situation on the basis of a coarse-grained ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Dislocation Behavior in TiVTa Multi-Principal Element Alloys: A Nanoindentation Simulation Study
CrystalsMolecular dynamics simulations of nanoindentation were conducted to compare the dislocation behavior in a pure V and a TiVTa multi-principal element alloy (MPEA) with [100] and [111] crystal orientations.

Applied Sciences, 2021 We observe a long-range distortion field between parallel dislocations with opposite Burgers vectors in a platelet-shaped single crystal of 4H-SiC with a low dislocation density (~103 cm/cm3).
