Ruthenium(IV) oxide is the inorganic compound with the formula Ru O 2. This black solid is the most common oxide of ruthenium . It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O 2 . [ 1 ]
Because the value from a given sensor is always stored at the same location in RAM, these sensor values can be read if the memory location is known. The 14CUX is capable of storing diagnostic trouble codes in a 32-byte segment of its internal memory that is maintained (even while vehicle ignition is off) by applying 5VDC ( regulated down from ...
Ruthenium has four crystal modifications and does not tarnish at ambient conditions; it oxidizes upon heating to 800 °C (1,070 K). Ruthenium dissolves in fused alkalis to give ruthenates (RuO 2− 4). It is not attacked by acids (even aqua regia) but is attacked by sodium hypochlorite at room temperature, and halogens at high temperatures. [11]
Ruthenium can be oxidized to ruthenium(IV) oxide (RuO 2, oxidation state +4), which can, in turn, be oxidized by sodium metaperiodate to the volatile yellow tetrahedral ruthenium tetroxide, RuO 4, an aggressive, strong oxidizing agent with structure and properties analogous to osmium tetroxide.
Strontium ruthenate is structurally very similar to the high-temperature cuprate superconductors, and in particular, is almost identical to the lanthanum doped superconductor (La, Sr) 2 CuO 4. However, the transition temperature for the superconducting phase transition is 0.93 K (about 1.5 K for the best sample), which is much lower than the ...
An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).
