Geran S. Dunlop, Mikayla Nisbet-Gore, Elliot P. Gilbert, Vincent S. J. Craig, Zachary Di Pietro, Stuart W. Prescott, Andrew R. J. Nelson, Alister J. Page, Grant B. Webber, Erica J. WanlessA comprehensive study of silica nanoparticles in concentrated electrolytes reveals universal re-entrant colloidal stability. Neutron scattering links colloidal stability in hypersaline conditions to open fractal aggregates rather than redispersion.
