Journal ArticleDOI
Collapse of sodium polyacrylate chains in calcium salt solutions
Ralf Schweins,Klaus Huber +1 more
TL;DR: In this article, a phase diagram of NaPA chains is presented, where the critical NaPA concentration is plotted versus the critical Ca2+ concentration resulting in a straight line as a phase boundary.
Journal ArticleDOI
Interpenetration of polymeric microgels at ultrahigh densities
Priti S. Mohanty,Priti S. Mohanty,Sofi Nöjd,Kitty van Gruijthuijsen,Jérôme J. Crassous,Marc Obiols-Rabasa,Ralf Schweins,Anna Stradner,Peter Schurtenberger +8 more
TL;DR: It is demonstrated that the microgels used in this study significantly interpenetrate and thus change their size and shape only marginally even for ϕeff ≫ ϕcp, a finding that may require changes in the interpretation of a number of previously published studies on the structural and dynamic properties of dense soft particle systems.
Journal ArticleDOI
Structure of micelles of poly(n-butyl acrylate)-block-poly(acrylic acid) diblock copolymers in aqueous solution
Olivier Colombani,Markus Ruppel,Markus Burkhardt,Markus Drechsler,Manuela Schumacher,Michael Gradzielski,Ralf Schweins,Axel H. E. Müller +7 more
TL;DR: In this paper, the structure and dynamics of micelles of the amphiphilic diblock copolymers poly(n-butyl acrylate)-block-poly(acrylic acid) (PnBA−PAA) were reported.
Journal ArticleDOI
Viscosity and diffusion: crowding and salt effects in protein solutions
Marco Heinen,Fabio Zanini,Felix Roosen-Runge,Diana Fedunova,Fajun Zhang,Marcus Hennig,Tilo Seydel,Ralf Schweins,Michael Sztucki,Marián Antalík,Frank Schreiber,Gerhard Nägele +11 more
TL;DR: In this paper, a joint experimental-theoretical study of collective diffusion in, and static shear viscosity of solutions of bovine serum albumin (BSA) proteins, focusing on the dependence on protein and salt concentration, is presented.
Journal ArticleDOI
Structure and Dynamics of Polyelectrolyte Complex Coacervates Studied by Scattering of Neutrons, X-rays, and Light
Evan Spruijt,F.A.M. Leermakers,Remco Fokkink,Ralf Schweins,Ad A. van Well,Martien A. Cohen Stuart,Jasper van der Gucht +6 more
TL;DR: In this article, the microscopic structure and density fluctuations of complex coacervates of flexible polyelectrolytes using scattering of neutrons, X-rays, and light were investigated.
