5.1.3. Gold (Au) and platinum (Pt) are mostly used for fabricating the IDE and wire heater with the photolithography method respectively. The resistive hydrogen sensors could be classified into two parts depending on sensitive material type such as semiconductor and metallic. The semiconducting and...
The suspended filament parts in the center of the emitting zone glow brighter than the filament near the guiding posts. b Diagram with multiple emission spectra from the IR emitter measured with the FTIR spectrometer. The relative intensity of the emitted IR radiation is plotted versus the ...
It is mainly composed of two parts, the plate tube bundle and the shell (pictured). The contact points of the cold-formed pair of slats are tightly welded together to form a plate tube containing multiple flat runners. The plate and shell heat exchanger is a structural f...
By how much is the cycle efficiency e increased if the heater temperature increases from T′1 = 400 K to T′2 = 600 K? 3.17 An ideal gas performs a Carnot cycle. The work of isothermal expansion of gas is A1 = 5 J. Define the work A2 of isothermal compression if thermal efficiency...
