(Nanowerk Spotlight) At the scale of individual atoms, materials behave in ways that defy everyday intuition. Stretch a metal wire by a few micrometers and its resistance changes only slightly.

Strain can be introduced to materials through various methods, including mechanical stretching, bending, compressing, or by epitaxial growth on substrates with different lattice constants. Advanced ...

Ishikawa, Japan - Sometimes, a material's property, such as magnetism and catalysis, can change drastically owing to nothing more than minute changes in the separation between its atoms, commonly ...

The fracture of materials is a very important issue for both structural and functional materials. Crack-tip behavior is among the most basic problems in fracture mechanics. Many theoretical and ...

“To improve transistor density and electronic performance, next-generation semiconductor devices are adopting three-dimensional architectures and feature sizes down to the few-nm regime, which require ...
