(FEI, USA) with primary energy of 10 keV and operating pressure of 5 × 10−6 Torr and constructed by Nova NanoSEM software (version 1.3.1). FTIR spectra were recorded with a liquid nitrogen-cooled (MCT) Spectrum 100 FTIR Spectrometer (PerkinElmer, USA) equipped with an ...
VOCs refer to those organic compounds with high vapor pressure at ordinary atmospheric temperature, which could easily evaporate from the liquid or solid form of this compound to enter the atmosphere. From: Encyclopedia of Sustainable Technologies, 2017 ...
This is because the pressure is reduced so too the boiling point. This is exactly the same in vacuum systems. A key piece of information to note is that the pressure 2340 Pa (23.4 mbar, 17.55 Torr) is the pressure at which water boils at room temperature (20°C). This pressure is ...
