Modern Surface Science and Surface Technologies: An Introduction
... Catalysts are usually small metal particles (2-20 nanometers) that are dispersed on a high surface area microporous oxide. Microelectronic devices are presently fabricated using techniques operating at ∼100 nm spatial resolution, but devices that must be fabricated and controlled on the 10 nm scale ...

Low temperature surface hardening of stainless steel
... These improvements rely on a modification of the surface adjacent region of the material, by the precipitation of alloying element nitrides/carbides or a continuous layer of iron-based carbonitrides. Generally, stainless steel is not nitrided or carburized, because the development of chromium nitrid ...

Ceramic Crystal Structures
... Some of the properties of ceramics may be explained by their structures. For example: (a) The optical transparency of inorganic glass materials is due, in part, to their noncrystallinity (b) the hydroplasticity of clays( i.e., development of plasticity upon the addition of water) is related to inter ...
