Recent developments of surface light scattering as a tool for optical-rheology of polymer monolayers
Pietro Cicuta, Ian Hopkinson
Surface Quasi-Elastic Light Scattering (SQELS) is an application of dynamic light scattering to measure the dynamics of the thermal roughness of liquid surfaces. An analysis of the…
Scaling of dynamics in 2d semi-dilute polymer solutions
Pietro Cicuta, Ian Hopkinson
We study the viscoelasticity of surface polymer monolayers by measuring the dynamics of thermal concentration fluctuations with surface light scattering. For various systems of pro…
Characterization of the Micromechanics in a Compressed Emulsion System: Force Distributions
Jasna Brujic, Sam F. Edwards, Ian Hopkinson +1
The micromechanics of a variety of systems experiencing a structural arrest due to their high density could be unified by a thermodynamic framework governing their approach to 'jam…
Dynamic light scattering from colloidal fractal monolayers
Pietro Cicuta, Ian Hopkinson
We address experimentally the problem of how the structure of a surface monolayer determines the visco-elasticity of the interface. Optical microscopy and surface quasi--elastic li…
Photocontrol of Protein Conformation in a Langmuir Monolayer
Pietro Cicuta, Ian Hopkinson, Peter G. Petrov
We report a method to control the conformation of a weak polyampholyte (the protein -casein) in Langmuir monolayers by light, even though the protein is not photosensitive. Our…
Studies of a weak polyampholyte at the air-buffer interface: The effect of varying pH and ionic strength
Pietro Cicuta, Ian Hopkinson
We have carried out experiments to probe the static and dynamic interfacial properties of --casein monolayers spread at the air-buffer interface, and analysed these results in t…
