82oxidation–reduction reaction — ▪ chemical reaction Introduction also called redox reaction any chemical reaction in which the oxidation number of a participating chemical species changes. The term covers a large and diverse body of processes. Many oxidation– reduction… …
83Samarium — promethium ← samarium → europium ↑ Sm ↓ …
84Electronic band structure — In solid state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy that an electron is forbidden or allowed to have. It is due to the diffraction of the quantum mechanical electron waves in the… …
85Semiconductor device — Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most …
86Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
87Electrical conduction — is the movement of electrically charged particles through a transmission medium (electrical conductor). The movement of charge constitutes an electric current. The charge transport may result as a response to an electric field, or as a result of… …
88conductive ceramics — Introduction advanced industrial materials that, owing to modifications in their structure, serve as electrical conductors. In addition to the well known physical properties of ceramic materials hardness, compressive strength,… …
89Nobel Prize controversies — Nobel Prize Awarded for Outstanding contributions in physics, chemistry, literature, peace, and physiology or medicine. The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, identified with the Nobel Prize, is awarded for… …
90Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable …
