As the aerospace sector pursues propulsion systems that are cleaner, quieter, and more efficient, materials used in turbine components face increasingly demanding thermal and mechanical environments.

The relaxed state of a type of topological defect (screw dislocation) located in a dispersive (non-local) elastic solid is discussed from a viewpoint of gauge field theory. The starting point of this ...

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. Dr. Edwin L. Thomas, professor in the ...

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University recently discovered a helicoidal-shaped ...

Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs ...

ACCORDING to the theory of Burton, Cabrera and Frank 1, crystals can only grow at supersaturations too low for two-dimensional nucleation, when dislocations are present. Where a screw dislocation ...
