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 ...

Wafer breakage is the most serious impact of killer crystalline defects. About 0.1 to 0.2% of silicon wafers break. The ...

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

Recently, a research group developed a giant magneto-superelasticity of 5% in a Ni34Co8Cu8Mn36Ga14 single crystal. This was achieved by introducing arrays of ordered dislocations to form ...

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 ...

With Bragg coherent diffractive imaging it is now possible to image the evolution of the entire dislocation network within a microcrystal during growth and dissolution. Figure 1: The effect of ...

Dislocations can save lives. This stems from the fact that the one-dimensional defects in a metal play an important role when the material deforms: for example, when a car body panel crumples in an ...

Simulations of defects inside copper point the way to making stronger metals. Results show that there are many different deformation mechanisms occurring in nano-structured materials like nanotwinned ...
