Nowadays, several well-studied materials in numerous fields like catalysis and electronics are in the vicinity of reaching their practical limits.
(left) Schematic illustration of the technique. The stiffness of nanomaterials such as platinum (Pt) atomic chains can be measured using a length-extension resonator (LER) made with a quartz crystal. The atomic structure of the chain can be observed using a transmission electron microscope (TEM). We found that the atomic bond strength in the Pt monoatomic chains is 25 N/m, which is higher than the bulk value (20 N/m).

Ishikawa, Japan - Today, many well-studied materials in various fields, such as electronics and catalysis, are close to reaching their practical limits. To further improve upon modern technology and outperform state-of-the-art devices, researchers looking for new functional materials have to push the boundaries and explore more extreme cases. A clear example of this is the study of low-dimensional materials, such as monoatomic layers (2D materials) and monoatomic chains (1D materials).
