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.
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Diamonds have long been coveted for their beauty. Their dazzling color and clarity make them perfect candidates for luxury jewelry. However, it's their other unique characteristics, including their hardness, thermal conductivity ...
