To resolve the kinetics of HPS aggregation, we have tracked the growth of the first nucleus formed. Based on the theoretical model obtained previously, we derived the equation for nucleus growth as follows: where n(t−Δt) is the size of the aggregate at time t−Δt. On the basis of equation (15), we obtained the … Meer weergeven A solution of HPS molecules dissolved in DMSO was continuously pumped into the centre microchannel. This central stream was … Meer weergeven In this paper, we employed the classical nucleation-growth theory40to model the time evolution of the total amount of aggregated HPS in solution. At each aggregation time point in this model, new nuclei are … Meer weergeven The free energy change associated with attaching a HPS monomer to an existing spherical aggregate containing nmolecules is where the … Meer weergeven We fitted the experimental measured fluorescence data to a theoretical model, which was built upon the classical nucleation-growth theory (equations (2)–(5)). In … Meer weergeven Web10 jun. 2024 · I know that the hydrophobic effect is usually explained by the entropic effect originating from the disruption of hydrogen bonds between molecules of water and the nonpolar substance. The hydrogen bonds are reoriented to minimize the disruption of the hydrogen bond network of water molecules.
