• The dynamics in ferrofluids are analysed theoretically, including the effects of interactions, structure, and polydispersity. equilibrium magnetisation non-equilibrium magnetic relaxation compared contrasted. Interactions lead to strong differences between two cases. influence structure formation is summarised. Polydispersity included into equations describing relaxation, unusual uncovered. L...

Eighty per cent of the proteoglycan of bovine nasal cartilage can be recovered in a purified preparation known as proteoglycan subunit; the preparation contains 87% chondroitin sulfate, 6% keratan sulfate, and 7% protein. The physical properties of proteoglycan subunit are not affected by exposure to 4 M guanidinium chloride, to reducing agents, or to pH 2.7. Proteoglycan subunit contains a sin...

Taylor dispersion analysis is an increasingly popular characterization method that measures the diffusion coefficient, and hence the hydrodynamic radius, of (bio)polymers, nanoparticles, or even small molecules. In this work, we describe an extension to current data analysis schemes that allows size polydispersity to be quantified for an arbitrary sample, thereby significantly enhancing the pot...
