Rojas-Ochoa, Luis Fernando Castañeda-Priego, R. Lobaskin, V. Stradner, Anna Scheffold, Frank Schurtenberger, Peter 2008-05-02 We determine the structure of charge-stabilized colloidal suspensions at low ionic strength over an extended range of particle volume fractions using a combination of light and small angle neutron scattering experiments. The variation of the structure factor with concentration is analyzed within a one-component model of a colloidal suspension. We show that the observed structural behavior corresponds to a nonmonotonic density dependence of the colloid effective charge and the mean interparticle interaction energy. Our findings are corroborated by similar observations from primitive model computer simulations of salt-free colloidal suspensions. application/pdf https://folia.unifr.ch/global/documents/300834 https://folia.unifr.ch/documents/300834/files/schurtenberger_ddi.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevLett.100.178304 info:eu-repo/semantics/openAccess License undefined Physical Review Letters. - 2008, vol. 100, p. 178304 Colloids Neutron scattering (condensed matter structure determination) Theory and models of liquid structure info:eu-repo/classification/udc/53 Density dependent interactions and structure of charged colloidal dispersions in the weak screening regime http://purl.org/coar/resource_type/c_6501
