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.
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical reactions are how you drive the movement of atoms, proteins, cells and bodies—without movement, ...
