was added to the chamber to study ternary nucleation and the role of acid-base clustering and nano-particle growth. To capture atmospherically relevant conditions, the amine concentration was kept several orders of magnitude lower than the concentrations used in previous laboratory studies16,18. The ...
They also show an increase in their zero proton condition (ZPC) with decreasing ionic strength. Here we examine the influence of the pH-independent charge of a solid on its acidbase properties. We consider two simple cases: model 1 in which all the acidbase groups and pH-independent charge...
