A slapper detonator, also called exploding foil initiator (EFI), is a detonator developed by Lawrence Livermore National Laboratory, US Patent No. 4,788,913 (Filed 1971, Granted 1988). It is an improvement over the earlier exploding-bridgewire detonator .
A new development is a slapper detonator, which uses thin plates accelerated by an electrically exploded wire or foil to deliver the initial shock. It is in use in some modern weapons systems. A variant of this concept is used in mining operations, when the foil is exploded by a laser pulse delivered to the foil by optical fiber.
Failed aluminium electrolytic capacitors with open vents in the top of the can, and visible dried electrolyte residue (reddish-brown color) The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, [1] [2] due to faulty electrolyte composition that ...
Americans have been using aluminum foil for over 100 years, since it was first used to wrap Life Savers, candy bars, and gum. ... this shouldn’t be a problem, as the amount of aluminum that is ...
A microwave oven uses a partial Faraday shield (on five of its interior six sides) and a partial Faraday cage, consisting of a wire mesh, on the sixth side (the transparent window), to contain the electromagnetic energy within the oven and to protect the user from exposure to microwave radiation.

Gallium arsenide monolithic microwave integrated circuits can have these failures: [11] Degradation of I DSS [12] by gate sinking and hydrogen poisoning. This failure is the most common and easiest to detect, and is affected by reduction of the active channel of the transistor in gate sinking and depletion of the donor density in the active ...

While foil chaff is still used by certain aircraft, such as the Boeing B-52 Stratofortress bomber, this type is no longer manufactured. The chaff used by aircraft such as the Fairchild-Republic A-10 Thunderbolt II , McDonnell Douglas F-15 Eagle , General Dynamics F-16 Fighting Falcon , and McDonnell Douglas F/A-18 Hornet consists of aluminium ...
