Journal ArticleDOI
Comparative Analysis of Viscosity of Complex Liquids and Cytoplasm of Mammalian Cells at the Nanoscale
Tomasz Kalwarczyk,Natalia Ziebacz,Anna Bielejewska,Ewa Zaboklicka,Kaloian Koynov,Jędrzej Szymański,Agnieszka Wilk,Adam Patkowski,Jacek Gapiński,Hans-Jürgen Butt,Robert Hołyst +10 more
TL;DR: A scaling formula for size-dependent viscosity coefficients for proteins, polymers, and fluorescent dyes diffusing in complex liquids was used to analyze the mobilities of probes of different sizes in HeLa and Swiss 3T3 mammalian cells.
Journal ArticleDOI
Scaling form of viscosity at all length-scales in poly(ethylene glycol) solutions studied by fluorescence correlation spectroscopy and capillary electrophoresis
Robert Hołyst,Anna Bielejewska,Jędrzej Szymański,Agnieszka Wilk,Adam Patkowski,Jacek Gapiński,Andrzej Zywocinski,Tomasz Kalwarczyk,Ewelina Kalwarczyk,Marcin Tabaka,Natalia Ziebacz,Stefan A. Wieczorek +11 more
TL;DR: For the smallest probes (rhodamine B and lysozyme) it is verified, using capillary electrophoresis and fluorescence correlation spectroscopy, that the Stokes-Einstein (SE) relation holds, providing that the size-dependent viscosity in the formula is used.
Journal ArticleDOI
Scaling the alpha-relaxation time of supercooled fragile organic liquids
TL;DR: In this paper, it was shown that the structural relaxation time of supercooled o-terphenyl depends on a single control parameter, which is the product of a function of density and temperature.
Journal ArticleDOI
Temperature and pressure study of Brillouin transverse modes in the organic glass-forming liquid orthoterphenyl.
TL;DR: It is shown that in the range of the experiment, the orientational time is depending on a unique parameter built on temperature and density, and this parameter appears to be always of the same order of magnitude.
Journal ArticleDOI
Many-body hydrodynamic interactions in charge-stabilized suspensions.

TL;DR: Using x-ray photon correlation spectroscopy, the hydrodynamic function H(q) can be quantitatively described by means of a novel Stokesian dynamics simulation method for charged Brownian spheres, and by a modification of a many-body theory developed originally by Beenakker and Mazur.
