Polyelectrolyte Knot Delocalization Induced by Counterion Condensation
Shensheng Chen, Tingtao Zhou
Knots on ring polymers tend to be tight. For knots on charged polymers (polyelectrolytes), electrostatic repulsion among the monomers is considered to enhance the persistence lengt…
Blistering Failure of Elastic Coatings with Applications to Corrosion Resistance
Surya Effendy, Tingtao Zhou, Henry Eichman +2
A variety of polymeric surfaces, such as anti-corrosion coatings and polymer-modified asphalts, are prone to blistering when exposed to moisture and air. As water and oxygen diffus…
Distribution and pressure of active Lévy swimmers under confinement
Tingtao Zhou, Zhiwei Peng, Mamikon Gulian +1
Many active matter systems are known to perform Lévy walks during migration or foraging. Such superdiffusive transport indicates long-range correlated dynamics. These behavior patt…
Soft-mode and Anderson-like localization in two-phase disordered media
Tingtao Zhou, Dimitrios Fraggedakis, Fan Wang
Wave localization is ubiquitous in disordered media -- from amorphous materials, where soft-mode localization is closely related to materials failure, to semi-conductors, where And…
Theory of Freezing Point Depression in Charged Porous Media
Tingtao Zhou, Mohammad Mirzadeh, Dimitrios Fraggedakis +2
Freezing in charged porous media can induce significant pressure and cause damage to tissues and functional materials. We formulate a thermodynamically consistent theory to model f…
Multiscale Poromechanics of Wet Cement Paste
Tingtao Zhou, Katerina Ioannidou, Franz-Josef Ulm +2
Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the…
Freezing point depression and freeze-thaw damage by nano-fuidic salt trapping
Tingtao Zhou, Mohammad Mirzadeh, Roland J. -M. Pellenq +1
A remarkable variety of organisms and wet materials are able to endure temperatures far below the freezing point of bulk water. Cryo-tolerance in biology is usually attributed to "…
Capillary stress and structural relaxation in moist granular materials
Tingtao Zhou, Katerina Ioannidou, Enrico Masoero +3
We propose a theoretical framework to calculate capillary stresses in complex mesoporous materials, such as moist sand, nanoporous hydrates, and drying colloidal films. Molecular s…
