Abstract:
... Understanding the emission sources of volatile organic compounds (VOCs) is critical for air pollution mitigation. Continuous measurements of atmospheric VOCs were conducted from January to February in Hangzhou in 2021. The average measured concentration of total VOCs (TVOCs) was 38.2 ± 20.9 ppb, > 42% lower than that reported by previous studies at the urban center in Hangzhou. The VOC concentrati ...

Abstract:
... The thermophoretic motion of nonionic colloids in an inhomogeneous temperature field is due to the solvent–colloid dispersion interactions. The latter form an attractive near-particle “gravity” field that leads to sinking of the colder solvent layers toward a colloid. The spatial extension of this microconvective motion is comparable to the size of the colloids, which prove to be small enough to o ...
