Screw Dislocation Assisted Spontaneous Growth of HfB2 Tubes and Rods

Water assisted growth of C₆₀ rods and tubes by liquid-liquid interfacial precipitation method.

C₆₀ nanorods with hexagonal cross sections are grown using a static liquid-liquid interfacial precipitation method in a system of C₆₀/m-dichlorobenzene solution and ethanol. Adding water to the ethanol phase leads instead to C₆₀ tubes where both length and diameter of the C₆₀ tubes can be controlled by the water content in the ethanol. Based on our observations we find that the diameter of the ...

Comparison of Acute Acromioclavicular Joint Dislocation Treatment by Screw Fixation with and without Ligament Reconstruction

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

Screw dislocation interacting with imperfect interface

The study of dislocations interacting with interfaces is of great interest to understand the strengthening and hardening mechanisms in materials. Most of the existing results in this field dealt with perfect interfaces where the displacements are continuous across interfaces. In reality, however, due to damage of interfaces or other reasons, the displacements across interfaces could have a jump...

Spontaneous patterning of confined granular rods.

Vertically vibrated rod-shaped granular materials confined to quasi-2D containers self-organize into distinct patterns. We find, consistent with theory and simulation, a density dependent isotropic-nematic transition. Along the walls, rods interact sterically to form a wetting layer. For high rod densities, complex patterns emerge as a result of competition between bulk and boundary alignment. ...
