thermocouple definition
two metals are put together side by side when heated, one metal expands more than another due to differences in the coefficients of thermal exansion, and the strip bends. This can be used as a switch, as in a thermostat.
thermovoltaic detector definition
an IR detector where temperature changes of a junction of dissimilar metals because of changes in the level of incident radiation causes a change in voltage.
thermogravimetric analysis (TGA) definition
when you heat a sample to observe weight changes; used when studying the loss of waters of hydration or CO2.
thermal oxidation definition
the reaction of silicon with oxygen at temperatures near 1000 degrees C to form silicon dioxide.
thioethers definition
Former name for sulfides RSR (R not equal to H). NOC Rule C-514.1, footnote.
