Chemistry in nanoconfined water.
Nanoconfined liquids have extremely different properties from the bulk, which profoundly affects chemical reactions taking place in nanosolvation. Here, we present extensive ab initio simulations of a vast set of chemical reactions within a water lamella that is nanoconfined by mineral surfaces, which might be relevant to prebiotic peptide formation in aqueous environments. Our results disclose...
متن کاملDynamic solidification in nanoconfined water films.
Mechanical properties of nanoconfined water layers are still poorly understood and continue to create controversy, despite their importance for biology and nanotechnology. We report on dynamic nanomechanical measurements of water films compressed to a few single molecular layers. We show that the mechanical properties of nanoconfined water layers change significantly with their dynamic state. I...

MEASURING THE NANOMECHANICS OF NANOCONFINED WATERLAYERS bySHAH HAIDAR KHANDecember 2010Advisor: Dr. Peter M. HoffmannMajor: PhysicsDegree: Doctor of Philosophy Nanoconfined water has been the subject of special interest due to its applications invarious fields such as biology, geology, medicine, and engineering tribology. While there is ageneral agreement on ...
متن کاملWettability effect on nanoconfined water flow.
Understanding and controlling the flow of water confined in nanopores has tremendous implications in theoretical studies and industrial applications. Here, we propose a simple model for the confined water flow based on the concept of effective slip, which is a linear sum of true slip, depending on a contact angle, and apparent slip, caused by a spatial variation of the confined water viscosity ...
متن کاملDynamics of nanoconfined water under pressure.
We report a study of the effects of pressure on the diffusivity of water molecules confined in single-wall carbon nanotubes (SWNT) with average mean pore diameter of ~16 Å. The measurements were carried out using high-resolution neutron scattering, over the temperature range 220≤T≤260 K, and at two pressure conditions: ambient and elevated pressure. The high pressure data were collected at cons...
