New material mimics strength, toughness of mother of pearl

ScienceDaily.com: Nanotechnology News - Wed, 07/15/2020 - 20:31
In the summer, many people enjoy walks along the beach looking for seashells. Among the most prized are those that contain iridescent mother of pearl (also known as nacre) inside. But many beachcombers would be surprised to learn that shimmery nacre is one of nature's strongest, most resilient materials. Now, researchers have made a material with interlocked mineral layers that resembles nacre and is stronger and tougher than previous mimics.

Higher-order topology found in 2D crystal

ScienceDaily.com: Nanotechnology News - Wed, 07/15/2020 - 19:14
The research team took a new approach by using the Josephson junctions to spatially resolve the supercurrent flow and to show that WTe2 does indeed appear to have hinge states and be a higher-order topological insulator. They have identified a new higher-order topological insulator. It is a layered two-dimensional transition metal dichalcogenide (TMDC) called WTe2. This is a famous material in condensed matter physics that displays a variety of exotic properties from titanic magnetoresistance to quantized spin hall effect.
