pluton
Science; General science
A solid rock body that formed by cooling and crystallization of molten rock (magma) within the Earth. Most plutons, or plutonic bodies, are regarded as the product of ...
transistor
Science; General science
A solid state device involved in amplifying small electrical signals and in processing of digital information. Transistors act as the key element in amplification, detection, and ...
polyhedron
Science; General science
A solid whose boundary consists of a finite number of polygonal faces, that is, planar regions that are bounded by polygons. The sides of the faces are edges of the polyhedron; ...
quasicrystal
Science; General science
A solid with conventional crystalline properties but exhibiting a point-group symmetry inconsistent with translational periodicity. Like crystals, quasicrystals display discrete ...
varactor
Science; General science
A solid-state device which has a capacitance that varies with the voltage applied across it. The name varactor is a contraction of the words variable and reactor. Typically the ...
thermoelectric power generator
Science; General science
A solid-state heat engine which employs the electron gas as a working fluid. It directly converts heat energy into electrical energy using the Seebeck effect. This phenomenon can ...
cholera
Science; General science
A severe diarrheal disease caused by infection of the small bowel of humans with Vibrio cholerae . This facultatively anaerobic, curved, gram-negative, rod-shaped bacterium is ...
