چکیده

In both experiment and molecular simulation, it is found that a higher pressure is required to sustain the infiltration of smaller ions in a molecular-sized nanochannel. Simulations indicate that the effective ion solubility of the infiltrated liquid is reduced to nearly zero. Because of the strong interactions between the ion couples and the solid or liquid phases, an external force is required to continuously advance the confined liquid segment. The competition between the probability of ion entry and ion-couple formation causes the observed ion-size-dependent characteristics.

Experimental study on energy dissipation of electrolytes in nanopores.

When a nonwetting fluid is forced to infiltrate a hydrophobic nanoporous solid, the external mechanical work is partially dissipated into thermal energy and partially converted to the liquid-solid interface energy to increase its enthalpy, resulting in a system with a superior energy absorption performance. To clarify the energy dissipation and conversion mechanisms, experimental infiltration a...

Effects of anion size and concentration on electrolyte invasion into molecular-sized nanopores

When an electrolyte solution is pressurized into a molecular-sized nanopore, oppositely charged ions are strongly inclined to aggregate, which effectively reduces the ion solubility to zero. Inside the restrictive confinement, a unique quasi-periodic structure is formed where the paired ion couples are periodically separated by a number of water molecules. As the anion size or ion concentration...

Effects of the addition of electrolyte on liquid infiltration in a hydrophobic nanoporous silica gel.

In this letter, we report the experimental results of pressure induced infiltration in the hydrophobic nanopores of a silica gel. The infiltration pressure increases with the prolonged surface treatment time, whereas the infiltration volume is not dependent on the surface coverage. When temperature increases, if the liquid phase is pure water, the infiltration pressure would decrease, which is ...

Time-dependent Gas-liquid Interaction in Molecular-sized Nanopores

Different from a bulk phase, a gas nanophase can have a significant effect on liquid motion. Herein we report a series of experimental results on molecular behaviors of water in a zeolite β of molecular-sized nanopores. If sufficient time is provided, the confined water molecules can be "locked" inside a nanopore; otherwise, gas nanophase provides a driving force for water "outflow". This is du...

Geometric Effects on Nanopore Creation in Graphene and on the Impact-withstanding Efficiency of Graphene Nanosheets

Abstract Single- and multilayer graphene sheets (MLGSs) are projectile-resisting materials that can be bombarded by nanoparticles to produce graphene sheets of various sizes and distributions of nanopores. These sheets are used in a variety of applications, including DNA sequencing, water desalination, and phase separation. Here, the impact-withstanding efficiency of graphene nanosheets and the...
