Particle Shape Anisotropy in Pickering Emulsions: Cubes and Peanuts

Autor: de Folter, J.W.J., Hutter, E.M., Castillo, S.I.R., Klop, K.E., Philipse, A.P., Kegel, W.K.

We have investigated the effect of particle shape in Pickering emulsions by employing, for the first time, cubic and peanut-shaped particles. The interfacial packing and orientation of anisotropic microparticles are revealed at the single-particle le

Interplay between Colloids and Interfaces : Emulsions, Foams and Microtubes

Autor: de Folter, J.W.J., Physical and Colloid Chemistry, Sub Physical and Colloid Chemistry

The central theme of this thesis is the interplay between colloids and interfaces. The adsorption of colloids at fluid-fluid interfaces is the main topic and covers Chapters 2-6. Pickering emulsions where colloidal particles act as emulsion stabilize

Helical Colloidal Sphere Structures through Thermo-Reversible Co-Assembly with Molecular Microtubes

Autor: Jiang, L., de Folter, J.W.J., Huang, J., Philipse, A.P., Kegel, W.K., Petukhov, A.V.

Self-assembly is ubiquitous in nature, science, and technology and provides a general route to achieve order from disorder at various length scales.[1] Extensive effort has been exerted to molecular and colloidal self-assembly, where molecules and co

Magnetic nanoparticles-induced anisotropic shrinkage of polymer emulsion droplets

Autor: Liu, B, de Folter, J.W.J., Möhwald, H., Physical and Colloid Chemistry, Afd Soft Condensed Matter and Biophysics, Sub Physical and Colloid Chemistry

Publikováno v: Soft Matter, 7, 3744. The Royal Society of Chemistry

We here report magnetic nanoparticles (NPs)-induced buckling instability and anisotropic shrinkage behavior of polymer emulsion droplets. The oil-in-water emulsion is stabilized by the surfactant, and NPs are dispersed into the oil phase. The surface

Evolution of equilibrium Pickering emulsions--a matter of time scales

Autor: Kraft, D.J., Luigjes, B., de Folter, J.W.J., Philipse, A.P., Kegel, W.K., Physical and Colloid Chemistry, Sub Physical and Colloid Chemistry, Sub Algemeen Scheikunde

Publikováno v: Journal of Physical Chemistry. B, 114(38), 12257. American Chemical Society

A new class of equilibrium solid-stabilized oil-in-water emulsions harbors a competition of two processes on disparate time scales that affect the equilibrium droplet size in opposing ways. The aim of this work is to elucidate the molecular origins o

Conditions for equilibrium solid-stabilized emulsions

Autor: Kraft, D.J., de Folter, J.W.J., Luigjes, B., Castillo, S.I.R., Sacanna, S., Philipse, A.P., Kegel, W.K., Physical and Colloid Chemistry, Sub Physical and Colloid Chemistry, Dep Scheikunde, Sub Algemeen Scheikunde

Publikováno v: Journal of Physical Chemistry. B, 114(32), 10347. American Chemical Society

Particular types of solid-stabilized emulsions can be thermodynamically stable as evidenced by their spontaneous formation and monodisperse droplet size, which only depends on system parameters. Here, we investigate the generality of these equilibriu

Rigid sphere transport through a colloidal gas–liquid interface

Autor: de Folter, J.W.J., de Villeneuve, V.W.A., Aarts, D.G.A.L., Lekkerkerker, H.N.W., Physical and Colloid Chemistry, Sub Physical and Colloid Chemistry, Dep Scheikunde

Publikováno v: New Journal of Physics, 12, 023013/1. IOP PUBLISHING LTD

In this paper we report on the gravity-driven transport of rigid spheres of various sizes through the fluid–fluid interface of a demixed colloid–polymer mixture. Three consecutive stages can be distinguished: (i) the sphere approaches the interfa

Residence and waiting times of Brownian interface fluctuations

Publikováno v: Europhysics Letters, 81(6), 60004/1. IOP PUBLISHING LTD

We report on the residence times of capillary waves above a given height h and on the typical waiting time in between such fluctuations. The measurements were made on phase-separated colloid-polymer systems by laser scanning confocal microscopy. Due

Life at ultralow interfacial tension: wetting, waves and droplets in demixed colloid-polymer mixtures

Autor: Lekkerkerker, H.N.W., de Villeneuve, V.W.A., de Folter, J.W.J., Schmidt, M., Hennequin, Y., Bonn, D., Indekeu, J.O., Aarts, D.G.A.L., Colloïden en grenslagen, Dep Scheikunde

Publikováno v: European physical journal. B, condensed matter physics, 64(3-4), 341. Springer New York

Mixtures of colloids and polymers display a rich phase behavior, involving colloidal gas (rich in polymer, poor in colloid), colloidal liquid (poor in polymer, rich in colloid) and colloidal crystal phases (poor in polymer, highly ordered colloids).

Dipolar structures in colloidal dispersions of PbSe and CdSe quantum dots

Autor: Klokkenburg, M., Houtepen, A.J., Koole, R., de Folter, J.W.J., Erne, B.H., van Faassen, E.E.H., Vanmaekelbergh, D.A.M.

We show by cryogenic transmission electron microscopy that PbSe and CdSe nanocrystals of various shapes in a liquid colloidal dispersion self-assemble into equilibrium structures that have a pronounced dipolar character, to an extent that depends on
