NANOTECHNOLOGY - NANOSCIENCE GLOSSARY

Following list of nanotechnologies and nanoscience definitions cannot be complete considering the complexity of the nanocomposite, nanotechnology and nanoscience field.
Nevertheless, we are convinced that are useful.

Definitions Nnotechnologies - Nanoscience - Nanomaterials


-Nano Biotechnology definition:

Bio-nanotechnology is concerned with molecular scale properties and applications of biological nanostructures and as such it sits at the interface between the chemical, biological and the physical sciences.

-Nanocomposite definition:

Nanomaterials that combine one or more separate components in order to obtain the best properties of each component (composite). In nanocomposite, nanoparticles (clay, metal, carbon nanotubes) act as fillers in a matrix, usually polymer matrix.

-Nanoelectronics definition:

Application of nanoscience and nanotechnologies techniques in the field of electronic. Nanotech applications in the field of electronics are especially promising: computer chips, optoelectronics, information storage, nanocomputer, sensors.

-Nanomachines definition:

Are devices built from individual atoms.Their size is measured in nanometers and they are built from individual atoms. The idea is that the assembler will be able to rearrange atoms from raw material in order to produce useful items.

-Nanomanufacturing definition:

Manufacturing at the nanoscale. The industrial application of nanotechnologies.

-Nanomaterials definition:

nanomaterials can be defined as materials which have structured components with at least one dimension less than 100nm. Materials that have one dimension in the nanoscale are layers, such as a thin films or surface coatings. Some of the features on computer chips come in this category. Materials that are nanoscale in two dimensions include nanowires and nanotubes. Materials that are nanoscale in three dimensions are particles, for example precipitates, colloids and quantum dots (tiny particles of semiconductor materials). Nanocrystalline materials, made up of nanometre-sized grains, also fall into this category.

-Nanomedecine definition:

Application of nanoscience and nanotechnologies techniques in the field of medecine. Areas such as disease diagnosis, drug delivery and molecular imaging are being intensively researched. Medical-related products containing nanoparticles are currently produced.

-Nanometre definition:

One nanometre (nm) is equal to one-billionth of a metre, 10-9m. Atoms are below a nanometre in size, whereas many molecules, including some proteins, range from a nanometre upwards.

-Nanometrology definition:

Nanometrology is the science of measurement at the nanoscale level. Nanometrology has a crucial role in order to produce nanomaterials and devices with a high degree of accuracy and reliability (nanomanufacturing).

-Nanoparticle definition:

Nanoparticles are particles of less than 100nm in diameter that exhibit new or enhanced size-dependent properties compared with larger particles of the same material.

-Nanoscale definition:

Scale with nanometre order of magnitude.

-Nanoscience definition:

Nanoscience is the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale.

-Nanostructure definition:

Nanostructure is a structure with arrangement of its parts in the nanometre scale.

-Nanotechnologies Nanotechnology definition:

Nanotechnologies are the design, characterisation, production and application of structures, devices and systems by controlling shape and size at nanometre scale.

-Nanotube definition (Carbon nanotubes):

Carbon nanotubes (CNTs) were discovered by Sumio Iijima in 1991. Carbon nanotubes are fullerene-related structures which consist of rolled graphene sheets. There are two types of CNT: single-walled (one tube) or multi-walled (more tubes). Both of these are typically a few nanometres in diameter and several micrometres to centimetres long.

-Nanowires definition:

Nanowires are ultrafine wires or linear arrays of dots, made from a wide range of materials.

-NEMS definition

Nano Electronics Mechanical System.
