Researchers design metamaterial that buckles selectively

Researchers from Leiden University, the Netherlands, have designed a novel metamaterial that buckles on demand. Small structural variations in the material single out regions that buckle selectively under external stress, ...

Nanocrystals not small enough to avoid defects

(Phys.org)—Nanocrystals as protective coatings for advanced gas turbine and jet engines are receiving a lot of attention for their many advantageous mechanical properties, including their resistance to stress. However, ...
