Using the FTIR-ATR technique, we investigated the heterogeneous nucleation process of aqueous (NH 4 ) 2 SO 4 binary droplets and (NH 4 ) 2 SO 4 /glycerol ternary droplets. From the red shift of δ -NH 4 + with a linearly declining relative humidity (

Hygroscopicity is capable of significantly affecting atmospheric visibility, radiative forcing, and cloud condensation nuclei process. Herein, a physisorption analyzer was adopted to determine the hygroscopicity of inorganic salt particles in atmosph

The conformational change of poly(vinyl alcohol) has been studied by Fourier transform infrared spectroscopy at various temperatures in the 4000–400 cm−1 region. The molecular motion and the trans/gauche content are sensitive to the C H, C C stre

The FTIR-ATR spectra of Na 2 SO 4 and mixed Na 2 SO 4 /glycerol (1:1) aerosols are monitored in the dehumidifying and humidifying process. It shows that glycerol suppresses both heterogeneous and homogeneous nucleation of Na 2 SO 4 /glycerol aerosols
