71Physical Sciences — ▪ 2009 Introduction Scientists discovered a new family of superconducting materials and obtained unique images of individual hydrogen atoms and of a multiple exoplanet system. Europe completed the Large Hadron Collider, and China and India took… …
72Thermocouple — plugged to a multimeter displaying room temperature in °C. A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either end of the pair of… …
73Nantenna — Figure 1. Spectral irradiance of wavelengths in the solar spectrum. The red shaded area shows the irradiance at sea level. There is less irradiance at sea level due to absorption of light by the atmosphere. A nantenna (nanoantenna) is a… …
74Charge-coupled device — A specially developed CCD used for ultraviolet imaging in a wire bonded package. A charge coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for… …
75Thermoelectric effect — The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. On the measurement scale of everyday life, a thermoelectric device creates a voltage when there is a different temperature on each… …
76Doping (semiconductor) — In semiconductor production, doping intentionally introduces impurities into an extremely pure (also referred to as intrinsic) semiconductor for the purpose of modulating its electrical properties. The impurities are dependent upon the type of… …
77Nanofluidic circuitry — is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic… …
78Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… …
79Electronic component — Various components An electronic component is a basic electronic element and may be available in a discrete form having two or more electrical terminals (or leads). These are intended to be connected together, usually by soldering to a printed… …
