  2. Alienware - Wikipedia

    en.wikipedia.org/wiki/Alienware

    Alienware Area-51m (discontinued) – 2019 desktop replacement gaming laptop with a desktop CPU, up to Intel Core i9-9900K (from i7 8700 to i9 9900K), 128 GB of upgradeable memory, upgradeable GPU (ships with GTX 1080 but will be upgraded to RTX 2080) and overclockable as well. Also features two power adapters and new Legend design language for ...

    en.wikipedia.org/wiki/Display_driver

    The display driver may itself be an application-specific microcontroller and may incorporate RAM, Flash memory, EEPROM and/or ROM. Fixed ROM may contain firmware and display fonts. A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)

  4. Anodizing - Wikipedia

    en.wikipedia.org/wiki/Anodizing

    The anodized aluminium layer is created by passing a direct current through an electrolytic solution, with the aluminium object serving as the anode (the positive electrode in an electrolytic cell). The current releases hydrogen at the cathode (the negative electrode) and oxygen at the surface of the aluminium anode, creating a build-up of ...

  5. Nickel–cadmium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–cadmium_battery

    Ni–Cd cells have a nominal cell potential of 1.2 volts (V). This is lower than the 1.5 V of alkaline and zinc–carbon primary cells, and consequently they are not appropriate as a replacement in all applications. However, the 1.5 V of a primary alkaline cell refers to its initial, rather than average, voltage.

  6. Zinc–air battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–air_battery

    Left side: Anode and gasket. Right side: Cathode and inlet opening for the atmospheric oxygen. A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte.

  7. Cathode ray - Wikipedia

    en.wikipedia.org/wiki/Cathode_ray

    But at the anode (positive) end of the tube, the glass of the tube itself began to glow. What was happening was that as more air was pumped from the tube, the electrons knocked out of the cathode when positive ions struck it could travel farther, on average, before they struck a gas atom.

  8. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    In this example, the salty food (lasagna) is the electrolyte, the aluminium foil is the anode, and the steel pan is the cathode. If the aluminium foil touches the electrolyte only in small areas, the galvanic corrosion is concentrated, and corrosion can occur fairly rapidly.

  9. Heel effect - Wikipedia

    en.wikipedia.org/wiki/Heel_effect

    In X-ray tubes, the heel effect or, more precisely, the anode heel effect is a variation of the intensity of X-rays emitted by the anode depending on the direction of emission along the anode-cathode axis. X-rays emitted toward the anode are less intense than those emitted perpendicular to the cathode–anode axis or toward the cathode.
