Low-Vacuum Deposition of Glutamic Acid and Pyroglutamic Acid: A Facile Methodology for Depositing Organic Materials beyond Amino Acids
Figure 12
The pressure-sensing performance of the QCR coated with the L-Glu-evaporated film: (a) schematics of the QCR measurement system depending on a change of pressure, (b) the pressure-dependent downward shift of frequency and upward shift of resistance. All of the shifts of frequency, resistance, and pressure are evaluated based on a constant condition under the N2-flow (200 mL/min) at 1013 hPa and 25°C.
