Fluids confined in nanopores are ubiquitous in nature and technology. In recent years, the interest in confined fluids has grown, driven by research on unconventional hydrocarbon resources—shale gas and shale oil, much of which are confined in nanopores. When fluids are confined in nanopores, many of their properties differ from those of the same fluid in the bulk. These properties include density, freezing point, transport coefficients, thermal expansion coefficient, and elastic properties…

The ω3 scaling of the vibrational density of states in quasi-2D nanoconfined solids

The vibrational properties of crystalline bulk materials are well described by Debye theory, which successfully predicts the quadratic ω2 low-frequency scaling of the vibrational density of states.

Mechanics under pressure of gold nanoparticle supracrystals: the role of the soft matrix

We report on High Pressure Small Angle X-ray Scattering (HP-SAXS) measurements on 3D face-centered cubic (FCC) supracrystals (SCs) built from spherical gold nanoparticles (NPs). Dodecane-thiol



Effect of pore geometry on the compressibility of a confined simple fluid.

These results, along with the development of the effective medium theories for nanoporous media, set the groundwork for analysis of the experimentally measured elastic properties of fluid-saturated nanoporous materials.

The pore size has a strong effect on the fluid bulk modulus, so that even at saturation, the elastic properties of nanoconfined fluid differ from the bulk values, and it is shown that this difference is also due to the adsorption stress.

Gassmann Theory Applies to Nanoporous Media

Recent progress in extraction of unconventional hydrocarbon resources has ignited the interest in the studies of nanoporous media. Since many thermodynamic and mechanical properties of nanoscale

Density Functional Study on Enhancement of Modulus of Confined Fluid in Nanopores

Elastic modulus in fluid is a crucial thermodynamic property due to its close relation to the viscoelastic behaviors in dynamics and the pore size analysis in porous materials. Especially, elasticity

Compressibility of Supercritical Methane in Nanopores: A Molecular Simulation Study

Unmineable coalbeds are a promising source of natural gas, and can act as a receptacle for CO2 sequestration. This is because they are composed of extensive nanoporous systems which allow for

Modeling elastic properties of Vycor glass saturated with liquid and solid adsorbates

A combination of ultrasonic experiments with gas adsorption is a promising tool for improved characterization of nanoporous materials. The use of ultrasound requires understanding of the effects of

Water Confined in Cylindrical Micropores

A model characterizing water-like fluids confined in cylindrical micropores is presented. The equation of state was derived based on perturbation theory assuming that the reference system of hard

Elastic properties of liquid and solid argon in nanopores

The measurements and their analysis show that longitudinal ultrasonic waves are well suited to the study of the elastic properties and liquid-solid phase transitions in porous systems and should also help to detect the influence of nanoconfinement on elastic properties in further research.
