Solid-liquid critical behavior of water in nanopores.
Nanoconfined liquid water can transform into low-dimensional ices whose crystalline structures are dissimilar to any bulk ices and whose melting point may significantly rise with reducing the pore size, as revealed by computer simulation and confirmed by experiment. One of the intriguing, and as yet unresolved, questions concerns the observation that the liquid water may transform into a low-di...
متن کاملSuperfluidity, BEC, and dimensions of liquid He in nanopores
We present path integral Monte Carlo (PIMC) calculations of the superfluid fraction, ρS/ρ, and the one-body density matrix (OBDM) [Bose-Einstein condensation (BEC)] of liquid He confined in nanopores. Liquid He in nanopores represents a dense Bose liquid at reduced dimension and in disorder. The goal is to determine the effective dimensions of the liquid in the pores. It is to test whether obse...
متن کاملLiquid-vapor oscillations of water in hydrophobic nanopores.
Water plays a key role in biological membrane transport. In ion channels and water-conducting pores (aquaporins), one-dimensional confinement in conjunction with strong surface effects changes the physical behavior of water. In molecular dynamics simulations of water in short (0.8 nm) hydrophobic pores the water density in the pore fluctuates on a nanosecond time scale. In long simulations (460...
متن کاملSilicon deposition in nanopores using a liquid precursor
Techniques for depositing silicon into nanosized spaces are vital for the further scaling down of next-generation devices in the semiconductor industry. In this study, we filled silicon into 3.5-nm-diameter nanopores with an aspect ratio of 70 by exploiting thermodynamic behaviour based on the van der Waals energy of vaporized cyclopentasilane (CPS). We originally synthesized CPS as a liquid pr...
متن کاملPressurized liquid in nanopores: a modified Laplace-Young equation.
In the current study, we analyze the motion of pressurized water molecules in nanopores of a well-crystallized, hydrophobic zeolite using both experiment and molecular dynamics simulation. It is discovered that, contradictory to the prediction of the classic Laplace-Young equation, the required infiltration pressure is highly dependent on the infiltration volume. A modified Laplace-Young equati...
