A team co-led by UC San Diego and the University of Michigan reports that short pulses of sound could remotely drag a structural defect through a metamaterial lattice, potentially letting researchers ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

One well-known example of such material defect that has been studied extensively over the past century, Upmanyu says, is a dislocation. It occurs when an entire atomic plane is missing from a ...

Defects such as cracks in a material are responsible for everything from malfunctioning microchips to earthquakes. Now MIT engineers have developed a model to predict a defect's birthplace, its ...

Topological defects in liquid crystals guide the self-assembly of molecular amphiphiles. Figure 1: Self-assembly of amphiphiles in nematic liquid-crystal defects. Abbott and co-workers' study raises ...

BERKELEY, Calif. — In a study at Lawrence Berkeley National Laboratory (LBNL), exposing certain thermoelectric materials to alpha-particle radiation has been shown to transform the materials into far ...
