Ionic current inversion in pressure-driven polymer translocation through nanopores
Sahin Buyukdagli, Ralf Blossey, T. Ala-Nissila
We predict streaming current inversion with multivalent counterions in hydrodynamically driven polymer translocation events from a correlation-corrected charge transport theory inc…
Iso-Flux Tension Propagation Theory of Driven Polymer Translocation: The Role of Initial Configurations
Jalal Sarabadani, Timo Ikonen, Tapio Ala-Nissila
We investigate the dynamics of pore-driven polymer translocation by theoretical analysis and molecular dynamics (MD) simulations. Using the tension propagation theory within the co…
Continuum modeling of mechanically-induced creep in dense granular materials
David Henann, Ken Kamrin
Recently, a new nonlocal granular rheology was successfully used to predict steady granular flows, including grain-size-dependent shear features, in a wide variety of flow configur…
The potential energy landscape and inherent dynamics of a hard-sphere fluid
Qingqing Ma, Richard M. Stratt
Hard-sphere models exhibit many of the same kinds of supercooled-liquid behavior as more realistic models of liquids, but the highly non-analytic character of their potentials make…
Controlling polymer translocation and ion transport via charge correlations
Sahin Buyukdagli, Tapio Ala-Nissila
We develop a correlation-corrected transport theory in order to predict ionic and polymer transport properties of membrane nanopores in physical conditions where mean-field electro…
Fluid Flows Created by Swimming Bacteria Drive Self-Organization in Confined Suspensions
Enkeleida Lushi, Hugo Wioland, Raymond E Goldstein
Concentrated suspensions of swimming microorganisms and other forms of active matter are known to display complex, self-organized spatio-temporal patterns on scales large compared…
