Self-assembly and percolation in magnetic colloids
Hauke Carstensen, Anne Krämer, Vassilios Kapaklis +1
We study the self-assembly of branching-chain networks and crystals in a binary colloidal system with tunable interactions. The particle positions are extracted from microscope ima…
Layering of magnetic nanoparticles at amorphous magnetic templates with perpendicular anisotropy
Apurve Saini, Julie A. Borchers, Sebastian George +5
We reveal the assembly of monodisperse magnetite nanoparticles of sizes 5 nm, 15 nm and 25 nm from dilute water-based ferrofluids onto an amorphous magnetic template with out-of-pl…
The viscoelastic signature underpinning polymer deformation under shear flow
Airidas Korolkovas, Sylvain Prévost, Maciej Kawecki +4
Entangled polymers are deformed by a strong shear flow. The shape of the polymer, called the form factor, is measured by small angle neutron scattering. However, the real-space mol…
Statistical analysis of phase formation in 2D colloidal systems
Hauke Carstensen, Vassilios Kapaklis, Max Wolff
Colloidal systems offer unique opportunities for the study of phase formation and structure since their characteristic length scales are accessible to visible light. As a model sys…
Polymer brush collapse under shear flow
Airidas Korolkovas, Cesar Rodriguez-Emmenegger, Andres de los Santos Pereira +6
Shear responsive surfaces offer potential advances in a number of applications. Surface functionalisation using polymer brushes is one route to such properties, particularly in the…
Combined neutron reflectometry and rheology
Max Wolff, Peter Kuhns, Georg Liesche +3
We have combined neutron reflectometry with rheology in order to investigate the solid boundary of liquids and polymers under shear deformation. Our approach allows one to apply a…
The search for Nanobubbles by using specular and off-specular Neutron Reflectometry
Philipp Gutfreund, Marco Maccarini, Andrew Dennison +1
We apply specular and off-specular neutron reflection at the hydrophobic silicon/water interface to check for evidence of nanoscopic air bubbles whose presence is claimed after an…
Depth resolved grazing incidence scattering from the solid-liquid interface
Max Wolff, Peter Kuhns, Andrew J C Dennison +3
We have applied small angle scattering in grazing incidence beam geometry on a time-of-flight neutron instrument. Due to the broad wavelength distribution provided for a specific i…
Solid Surface Structure Affects Liquid Order at the Polystyrene/SAM Interface
Philipp Gutfreund, Oliver Bäumchen, Dorothee van der Grinten +5
We present a combined x-ray and neutron reflectivity study characterizing the interface between polystyrene (PS) and silanized surfaces. Motivated by the large difference in slip v…
