Publikováno v: Dalton Transactions, 2008(21), 2861. Royal Society of Chemistry

The polyoxometalates or POMs (clusters comprising at least two metal and many oxygen atoms) have recently gained significant interest owing to their versatile architecture and especially their catalytic activities. Due to their high catalytic activit

Monte Carlo simulations of in-plane stacking disorder in hard-sphere crystals

Autor: Miedema, P.S., de Villeneuve, V.W.A., Petukhov, A.V., Colloïden en grenslagen, Dep Scheikunde, Physical and Colloid Chemistry 1

Publikováno v: Physical Review. E, Statistical, nonlinear, and soft matter physics, 77(1), 010401. American Physical Society

On-lattice Monte Carlo simulations of colloidal random-stacking hard-sphere colloidal crystals are presented. The model yields close-packed crystals with random-stacking hexagonal structure. We find a significant amount of in-plane stacking disorder,

Rheological, optical and structural properties of colloidal suspensions of charge-stabilized gibbsite platelets across the sol–gel transition region are investigated. In this work we focus on samples with a low salt content (10−4 M). While at a g

Dipolar structures in magnetite ferrofluids studied with small-angle neutron scattering with and without applied magnetic field

Publikováno v: Physical Review. E, Statistical, nonlinear, and soft matter physics, 75, 051408. American Physical Society

Field-induced structure formation in a ferrofluid with well-defined magnetite nanoparticles with a permanent magnetic dipole moment was studied with small-angle neutron scattering (SANS) as a function of the magnetic interactions. The interactions we

Publikováno v: Journal of Applied Crystallography, 40, 144. International Union of Crystallography

A simple model is presented that allows calculation of the small-angle X-ray diffraction patterns of perfect colloidal crystals. The model is based on the Wentzel–Kramers–Brillouin approximation and permits a straightforward evaluation of multibe

Publikováno v: Langmuir, 99, 11343. American Chemical Society : Division of Carbohydrate Chemistry

We demonstrate that highly polydisperse colloidal gibbsite platelets easily form an opal-like columnar crystal with striking iridescent Bragg reflections. The formation process can be accelerated by orders of magnitude under a centrifugation force of
