Across the physical world, many intricate structures form via symmetry breaking. When a system with inherent symmetry transitions into an ordered state, it can form stable imperfections known as ...

(Nanowerk News) Halide perovskite is perhaps the most promising candidate for next-generation solar cells, with the efficiency quickly approaching that of commercial silicon cell but at a much lower ...

The small and complicated features of TSVs give rise to different defect types. Defects can form during any of the TSV process steps, which include lithography patterning followed by deep reactive ion ...

(Nanowerk News) Two-dimensional materials are essential for developing new ultra-compact electronic devices, but producing defect-free 2D materials is a challenge. However, discovery of new types of ...

Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, ...

When a material fails, it can have devastating consequences – making bridges collapse or pipelines explode. Tomas Martin and Stacy Moore describe how innovative and complementary microscopy and ...

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.
