Materials science is an interdisciplinary field of researching and discovering materials. Materials engineering is an engineering field of finding uses for materials in other fields and ...
Smart materials, also called intelligent or responsive materials, [1] [page needed] are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds.
A material is a substance or mixture of substances that constitutes an object.Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function.
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. [1] The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software.
The term nanoporous materials contain subsets of microporous and mesoporous materials. Microporous materials are porous materials with a mean pore size smaller than 2 nm, while mesoporous materials are those with pores sizes in the region 2–50 nm. [23] Microporous materials exhibit pore sizes with comparable length-scale to small molecules.
Programmable matter seeks to design materials whose properties can be easily, reversibly and externally controlled though a fusion of information science and materials science. Due to the popularity and media exposure of the term nanotechnology, the words picotechnology and femtotechnology have been coined in analogy to it, although these are ...
Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond.

Materials and/or processes have been characterized for manufacturability and availability but further evaluation and demonstration is required. Milestone A decision: 4: Capability to produce the technology in a laboratory environment. Required investments, such as manufacturing technology development identified.
