schottky barrier diode
Science; General science
A metal-semiconductor diode (two terminal electrical device) that exhibits a very nonlinear relation between voltage across it and current through it; formally known as a metallic ...
powder metallurgy
Science; General science
A metalworking process used to fabricate parts of simple or complex shape from a wide variety of metals and alloys in the form of powders. The process involves shaping of the ...
quartzite
Science; General science
A metamorphic rock consisting largely or entirely of quartz. Most quartzites are formed by metamorphism of sandstone; but some have developed by metasomatic introduction of ...
hornfels
Science; General science
A metamorphic rock that has been subjected to heating during contact metamorphism around intrusive igneous rocks. Hornfels is typically fine-grained, although where it is ...
lawsonite
Science; General science
A metamorphic silicate mineral related chemically and structurally to the epidote group of minerals. Its composition is Ca(H 2 O)Al 2 (OH) 2 (Si 2 O 7 ), and it is a sorosilicate ...
population dynamics
Science; General science
A metapopulation is a set of geographically distinct local populations occupying discrete habitat patches. In some patches, the local population can become extinct—for example, if ...
combinatorial synthesis
Science; General science
A method for preparing a large number of chemical compounds, commonly known as a combinatorial library, which are then screened to identify compounds having a desired function, ...
