Study on enhancing coal dust wettability by surfactant compounding with different ion types

Meikuang Anquan
To improve the wetting effect of surfactants on coal dust, the influences of three compound systems, namely anionic + nonionic, anionic + cationic, and cationic + nonionic surfactants, on the wettability of coal dust were investigated through experiments

Recent and future trends in synthetic greenhouse gas radiative forcing [PDF]

, 2013
Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (SGHG) radiative forcing. We infer recent SGHG emissions and examine the
