The aim of our work was to study the structure of a typical modern cosmetic oil-in-water emulsion (o/w-emulsion), based on the emulsifier polyglyceryl-3 dicitrate/stearate and glycerylstearate/stearyl alcohol as consistency enhancer. We have used a s

Stable oleate capped, visible light emitting ZnO quantum dots (QDs) have been synthesized by a modified sol–gel method and examined for large-scale synthesis. Surface chelation with oleate ligands and their implications on particle growth were inve

Visible light emitting ZnO quantum dots (QDs) were synthesized by a modified sol–gel method and in situ coated with the amino acid cysteine to modify their surface chemistry and govern the crystal growth process. Surface chelation by a hydrophilic

We present a study of the structure and local dynamics of dispersed silica nanoparticles in the liquid crystal 4′-pentyl-4-biphenylcarbonitrile (5CB). Electron microscopy and X-ray scattering data demonstrate that the nanoparticles form agglomerate

New images by freeze fracture electron microscopy (FFEM) are obtained for microemulsions in the ternary system water–n-octane–C12E5 as function of varying water-to-oil ratio. The surfactant concentration is chosen such that the composition of the

Control over the self-assembly of magnetic nanoparticles (MNP) into superstructures due to different types of coupling is of interest in the development of "bottom-up" fabrication schemes. Here we realize a simple strategy for the systematic variatio

Static and dynamic light scattering experiments are carried out with solutions of a high molar mass polystyrene (Mw=0.96×106 g mol-1) in cyclohexane at different concentrations of the polymer. At the Θ-temperature TΘ the critical concentration of

Static light scattering experiments with C 12 E 5 /D 2 O mixtures are carried out in the large aggregate region of the phase diagram of the system adjacent to the lower part of the binodal curve. They demonstrate the existence of concentration fluctu
