Probing cage relaxation in concentrated protein solutions by XPCS
Yuriy Chushkin, Alessandro Gulotta, Felix Roosen-Runge +3
Diffusion of proteins on length scales of their own diameter in highly concentrated solutions is essential for understanding the cellular machinery of living cells, but its experim…
Extending depolarized DLS measurements to turbid samples
Antara Pal, Peter Holmqvist, Andrea Vaccaro +1
The application of dynamic light scattering to soft matter systems has strongly profited from advanced approaches such as the so-called modulated 3D cross correlation technique (mo…
Probing roto-translational diffusion of small anisotropic colloidal particles with a bright-field microscope
Fabio Giavazzi, Antara Pal, Roberto Cerbino
Soft and biological materials are often composed of elementary constituents exhibiting an incessant roto-translational motion at the microscopic scale. Tracking this motion with a…
Phase behavior of two-component lipid membranes: theory and experiments
Md. Arif Kamal, Antara Pal, V. A. Raghunathan +1
The structure of the ripple phase of phospholipid membranes remains poorly understood in spite of a large number of theoretical studies, with many experimentally established struct…
A defect mediated lamellar to isotropic transition of amphiphile bilayers
Antara Pal, Georg Pabst, V. A. Raghunathan
We report the observation of a novel isotropic phase of amphiphile bilayers in a mixed system consisting of the ionic surfactant, sodium docecylsulphate (SDS), and the organic salt…
Theory of the asymmetric ripple phase in achiral lipid membranes
Md. Arif Kamal, Antara Pal, V. A. Raghunathan +1
We present a phenomenological theory of phase transitions in achiral lipid membranes in terms of two coupled order parameters -- a scalar order parameter describing lipid chain mel…
