Nov 19, 2020 The high copper concentration (6,500 ppm) in GXR4 interferes with both the zinc K alpha line and background measured at 40.5 2θ. Attempts to correct element counts with background taken at 40.5 and 46.5 2θ or using the tungsten X-ray tube target radiation as an internal standard were not successful
Uses of Rare Earth Elements. Rare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and much more

The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chain-driven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms
