Методы получения и применение наноматериалов

Abstract

Nanomaterials is а field which takes a materials science-based approach to nanotechnology. It studies materials with morphological features on the nanoscale, and especially those which have special properties stemming from their nanoscale dimensions. Nanoscale is usually defined as smaller than a one tenth of a micrometer in at least one dimension, though this term is sometimes also used for materials smaller than one micrometer. The first observations and size measurements of nano-particles were made during the first decade of the 20th century. They are mostly associated with the name of Zsigmondy who made detailed studies of gold sols and other nanomaterials with sizes down to 10 nm and less. There are traditional techniques developed during 20th century in Interface and Colloid Science for characterizing nanomaterials. These are widely usedfor first generation passive nanomaterials specified in the next section.
