Spectroscopy techniques greatly advance the comprehensive understanding of air pollution evolution6,7,8,9, especially with the broad application of ground-based and space-based passive and active remote sensing. Since the 1990s, numerous space-borne ultraviolet-visible (UV-Vis) spectrometers, e.g., ...
A 36 channel reactor system combining high-throughput experimentation (HTE) with operando UV/vis diffuse reflectance (UV/vis-DR) spectroscopy is introduced and applied for the oxidative dehydrogenation of propane (ODP) to propene at 500 掳C over polycrystalline V 2O 3, VO 2, and V 2O 5. ...

Then, the optical properties of these chiral Ce3+-based halides were investigated via UV-visible (UV-vis) diffuse reflectance spectroscopy. As shown in Figure 2a, both R-MCC and S-MCC exhibit almost identical absorption edges at approximately 354 nm owing to their enantiomeric nature. There ...
