To overcome the traditional paradigm of filtration, where separation is essentially performed upon steric sieving principles, we explore the concept of dynamic osmosis through active membranes. A partially permeable membrane presents a time-tuneable feature that changes the effective pore interaction with the solute and thus actively changes permeability with time. In general, we find that slow flickering frequencies effectively decrease the osmotic pressure and large flickering frequencies do… Expand

An update on passive transport in and out of plant cells
Transport across membranes is critical for plant survival. Membranes are the interfaces at which plants interact with their environment. The transmission of energy and molecules into cells providesExpand


Nanofluidic osmotic diodes: theory and molecular dynamics simulations.
It is shown that a surface charge asymmetry built on a nanochannel surface leads to nonlinear couplings between water flow and the ion dynamics, which are capable of water flow rectification. Expand
Osmosis, from molecular insights to large-scale applications.
A global and unifying view of the phenomenon of osmosis and its consequences with a multi-disciplinary perspective is given and a number of examples along these lines are highlighted, for example introducing the concepts of Osmotic diodes, active separation and far from equilibrium Osmosis, raising in turn fundamental questions in the thermodynamics of separation.

Osmotic and diffusio-osmotic flow generation at high solute concentration. I. Mechanical approaches.
It is demonstrated in particular how the general expression of the osmotic pressure for mixtures emerges from the mechanical balance controlling non-equilibrium transport under solute gradients, as obtained classically from the thermodynamic framework. Expand
Giant osmotic energy conversion measured in a single transmembrane boron nitride nanotube
The fabrication and use of a hierarchical nanofluidic device made of a boron nitride nanotubes that pierces an ultrathin membrane and connects two fluid reservoirs is described, which allows the detailed study of fluidic transport through a single nanotube under diverse forces, including electric fields, pressure drops and chemical gradients.

Osmosis with active solutes
Despite much current interest in active matter, little is known about osmosis in active systems. Using molecular dynamics simulations, we investigate how active solutes perturb osmotic steady states.Expand
Active sieving across driven nanopores for tunable selectivity.
This work investigates a simple model for an active noisy nanopore, where gating-in terms of size or charge-is externally driven at a tunable frequency, and unveils a rich sieving diagram in terms of the forced gating frequency. Expand
Single-layer MoS2 nanopores as nanopower generators
A large, osmotically induced current is observed produced from a salt gradient with an estimated power density of up to 106 watts per square metre—a current that can be attributed mainly to the atomically thin membrane of MoS2, thus demonstrating a self-powered nanosystem. Expand
Enhanced water permeability and tunable ion selectivity in subnanometer carbon nanotube porins
Water permeability in 0.8-nanometer-diameter carbon nanotube porins (CNTPs), which confine water down to a single-file chain, exceeds that of biological water transporters and of wider CNT pores by an order of magnitude. Expand
Precise and Ultrafast Molecular Sieving Through Graphene Oxide Membranes
This work investigates permeation through micrometer-thick laminates prepared by means of vacuum filtration of graphene oxide suspensions, which reveal that the GO membrane can attract a high concentration of small ions into the membrane, which may explain the fast ion transport. Expand
A Physical Interpretation of the Phenomenological Coefficients of Membrane Permeability
A "translation" of the phenomenological permeability coefficients into friction and distribution coefficients amenable to physical interpretation is presented and a set of equations and reference curves are presented for the evaluation of ω and σ in the transport of polyvalent ions through charged membranes.
