This present study was conducted to investigate the effect of adding hydrophobically modified end-capped (HM) polymers with various polyethylene oxide (PEO) chain lengths on the structure and viscosity of anionic vesicles dispersion. A pronounced increase in viscosity was observed upon adding small amount of such polymers. Based on the dynamic light scattering (DLS) and small angle neutron scattering (SANS) analysis, 10 to 30 polymer molecules per vesicles can reach maximum viscosity and where polymer molecules can interconnect the vesicles without disrupting their structure. In addition, the kinetic stability of the vesicle dispersion also enhanced. From the measurement of the electrical conductivity of the dispersion, it was observed that the presence of the PEO and polypropylene oxide (PPO) group could induce the permeability of the vesicle membrane by altering their internal structure. Controlling viscosity of vesicles dispersion without changing its structure is useful for the further application of vesicles system such as in drug delivery, cosmetics and biomedical.

The paper study on the properties of Tricalcium Silicate (C3S) in different physical and chemical environment, the results suggest that neither chemically nor by way of adsorption and that the physically bound water could not act as a solvent for the ethanolamine. Small-angle neutron scattering studies allow a nondestructive description of statistically representative microstructures in the scale range from micrometer to nanometer. Moreover, the scattering signals can be analyzed in a variety of ways, and more detailed insight can be provided into the very complex cement paste microstructure.
