regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. in this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. this contrasts with conventional braking .
that portion of the applied magnetic field that the material retains when the external field is removed. remote racking system a system for inserting circuit breakers into switchgear that allows the operator to stay at a safe distance from any possible arc hazard. remote sensing

the shredders cut the electronics into metallic and non-metallic pieces. metals are extracted using magnetic separators, air flotation separator columns, shaker tables or eddy currents. the plastic almost always contains regulated hazardous waste e.g., asbestos, pcbs, hydrocarbons and cannot be melted down.
crushed ore is washed over mercury-coated copper sheets, and fine gold particles form an amalgam with the mercury. the amalgam was scraped off and the gold then separated from the amalgam by heating and evaporating the mercury, which was then recovered by a condenser for reapplication to the plates.
red iron iii oxide fe 2 o 3, commonly known as rust is the most common iron oxide used in thermite. magnetite also works. other oxides are occasionally used, such as mno 2 in manganese thermite, cr 2 o 3 in chromium thermite, quartz in silicon thermite, or copper ii oxide in copper thermite, but only for specialized purposes.

jaw crushers are heavy duty machines and hence need to be robustly constructed. the outer frame is generally made of cast iron or steel. the jaws themselves are usually constructed from cast steel. they are fitted with replaceable liners which are made of manganese steel, or ni-hard a ni-cr alloyed cast iron .
dental amalgam is a liquid mercury and metal alloy mixture used in dentistry to fill cavities caused by tooth decay. low-copper amalgam commonly consists of mercury 50% , silver 22–32% , tin 14% , copper 8% and other trace metals.. dental amalgams were first documented in a tang dynasty medical text written by su gong 苏恭 in 659, and appeared in germany in 1528.
