We have studied the effect of gaseous pollutants on fog droplet growth in heavily polluted air using a model that describes time-dependent sulfate production in the liquid phase and thermodynamical equilibrium between the droplets and the gas phase. Our research indicates that the oxidation of SO 2 to sulfate has a significant effect on fog 5 droplet growth especially when hygroscopic trace gas...

Hygroscopic effects in ionic liquids and salts general, how to suppress said hygroscopy, often needs be considered during the everyday work routine. Chemicals that decompose, undergo hydrolysis or any way change their composition when exposed air are generally not bench-stable. In this study, we synthesized a low-hygroscopic, bench-stable carbohydrate-based hydroxide salt. This new product was ...

The phase change of water from liquid to vapor is one of the most energy-intensive physical processes in nature, giving it immense potential for cooling. Diverse evaporative cooling strategies have resulted worldwide, including roof ponds and sprinklers, courtyard fountains, wind catchers with qanats, irrigated green roofs, and fan-assisted evaporative coolers. These methods all require water i...
