Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

The ‘Tapping Mode SQUID-on-Tip’ (TM-SOT) microscope enables multimodal imaging to be performed extremely close to the sample ...

Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms, even the tiniest flaw matters. Researchers at Rice University have shown ...

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 ...

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 ...
