Nanostructures, as a physical system, are materials or assemblies characterized by at least one spatial dimension in the nanometer range (typically 1–100 nm), where quantum confinement, high surface-to-volume ratio, and size-dependent effects dominate their physical behavior. They include zero-, one-, two-, and three-dimensional architectures such as quantum dots, nanowires, nanotubes, and nanoporous frameworks. In this size regime, electronic, optical, mechanical, and thermal properties deviate markedly from bulk counterparts, enabling tunable band gaps, altered phonon and electron transport, and enhanced catalytic activity. Nanostructures are central platforms in nanophotonics, nanoelectronics, energy conversion, and sensing, where controlled synthesis, morphology, and interface engineering critically determine system performance.

Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. ...
Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows ...
Composed of five or more elements in nearly equal amounts, high-entropy alloys (HEAs) have emerged as promising catalysts due to their compositionally complex surfaces that can accelerate chemical reactions. Until now, scientists ...
