Strength can be controlled by edge dislocations in refractory high-entropy alloys. Nature Communications, 2021; 12 (1) DOI: 10.1038/s41467-021-25807-w ...

Screw suspension 6,11,56–59 is, as its name implies, a method of suspending the scapula from the clavicle by a vitallium lag screw (Fig. 3) until the torn coracoclavicular ligaments heal.

Real Materials Internal Boundaries Low angle boundaries can be formed by dislocation arrays. For a uniform edge dislocation spacing, d, the grain boundary angle, θ, is given by: tanθ = b/D where b is ...

The researchers retrospectively reviewed data for 21 patients with old odontoid fractures (13 men and 8 women; mean age, 46.5 years) who underwent internal screw fixation via the C1 and C2 pedicle.

Researchers have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice ...

For both jogs and kinks the Burgers vector and line vector are those of the dislocation, the line vector being along the direction of the jog or the kink. These features may therefore be of a ...

Recurrent dislocations occurred in 8.3% of patients treated with button fixation vs. 2.5% of patients treated with screw fixation, according to Schoch.
