The nanoscale wear and friction of silica and silicon nitride surfaces in aqueous electrolyte solutions were investigated by using sharp atomic force microscope (AFM) cantilever tips coated with silicon nitride. Measurements were carried out in aqueous solutions of varying pH and in monovalent and divalent cation chloride and nitrate solutions. The silica surface was shown to wear strongly in solutions of high pH (≈11.0), as expected, but the presence of simple cations, such as Cs(+) and Ca(2…

Cation effects on haemoglobin aggregation: balance of chemisorption against physisorption of ions
TLDR
A theoretical model of haemoglobin is presented to explain an anomalous cationic Hofmeister effect observed in protein aggregation, which results in stronger attractive forces and greater aggregation with K+, leading to the non-conventional Hofmeisters series K+ > Cs+ ≈ Li+.
