Journal ArticleDOI
Two-stage melting of paramagnetic colloidal crystals in two dimensions
TL;DR: In this article, a two-dimensional system of colloidal particles with absolutely calibrated magnetic interaction is used to investigate static and dynamic properties at the 2D crystal to liquid phase transition, in perfect agreement with the theory of Kosterlitz and Thouless.
Journal ArticleDOI
Observation of the critical regime near Anderson localization of light.
TL;DR: Time resolved measurements of light transport through strongly scattering samples with kl* values as low as 2.5 constitute an experimental realization of the critical regime in the approach to Anderson localization.
Journal ArticleDOI
Dynamic Criteria for Melting in Two Dimensions
Klaus Zahn,Georg Maret +1 more
TL;DR: Using video microscopy complete positional data are obtained over five decades in time for an ensemble of superparamagnetic colloidal particles confined to an air-water interface and it is found that each of the three phases is uniquely characterized by the long-time behavior of gamma(L)(t), g(6)(t) and the non-Gaussian parameter of the relative neighbor-neighbor displacement.
Journal ArticleDOI
Synthesis and Characterization of Porous and Nonporous Monodisperse Colloidal TiO2 Particles
TL;DR: In this paper, the influence of different salt ions or polymer molecules on the size and distribution of the final titania particles was investigated, and electron microscopy, thermogravimetry, 1H-MAS NMR, X-ray absorption spectroscopy, and electrophoresis.
Journal ArticleDOI
Localization or classical diffusion of light
TL;DR: In this paper, it was shown that the turbidities of Wiersma et al.'s data can be explained by classical diffusion combined with reasonable amounts of absorption, and the turbidity of their samples are comparable to samples with classical transport properties.
