WebJun 19, 2013 · With these values at hand, the DLVO theory is capable to accurately predict the measured forces in the asymmetric systems down to distances of 2–3 nm without adjustable parameters. This success indicates that DLVO theory is highly reliable to quantify interaction forces in such systems.
WebJun 17, 2024 · The Derjaguin approximation (DA) relates the force between curved surfaces to the interaction free energy between parallel planes. It is typically derived by considering the direct interaction between the bodies involved, thus treating the effect of an intervening solvent implicitly by a rescaling of the corresponding Hamaker constant.
