Pressure effects in confined nanophases

Molecular Simulation, 2014
In this article, we review how pressure effects in pores affect both the physics of the confined fluid and the properties of the host porous material.

Mirror confinement and control through radiation pressure

Optics Letters, 1984
The control of the position of a mirror by radiation pressure is analyzed theoretically. Under realistic noise conditions, the position of a light mirror suspended inside a fixed Fabry-Perot interferometer can be stabilized within a few nanometers with incident powers of less than 1 W.

Pressure confinement effect in MoS₂monolayers

Nanoscale, 2015
With ever increasing interest in layered materials, molybdenum disulfide has been widely investigated due to its unique optoelectronic properties. Pressure is an effective technique to tune the lattice and electronic structure of materials such that high pressure studies can disclose new structural and optical phenomena.

Statistics of confined self-avoiding walks. II. Entropy and pressure of confinement

Journal of Physics A: Mathematical and General, 1994
For pt. 1, see ibid., vol. 27, p. 2653, (1994). Self-avoiding walks (SAWs) up to 198 steps and random-flight walks (RFWs) up to 598 steps were computer generated. The entropy change upon confinement of the walks, as well as the pressure exercised by corresponding chains obeying Hamiltonian mechanics on the surface of the confining spheres, was derived ...

Confining Pressure, Grain Angularity, and Liquefaction

Journal of Geotechnical Engineering, 1985
Substantial decrease in resistance to liquefaction is shown to occur with increase in confining pressure for a rounded and an angular sand having identical gradation. For a given increase in confining pressure, angular sand suffers a larger loss in resistance than rounded sand.

Pressure Distribution in Confined Jet Flow

Journal of Fluids Engineering, 2014
A momentum jet injected into a confined container breaks up to “diffusive turbulence” after traveling a critical distance. It has been argued that an adverse pressure gradient developing within the container, acting against the jet momentum flux, is responsible for this break up (Risso and Fabre, 1997,“Diffusive Turbulence in a Confined Jet Experiment,”

Deformation of Chalk Under Confining Pressure and Pore Pressure

Society of Petroleum Engineers Journal, 1981
Abstract Compression tests with and without pore pressure have been run on Danian and Austin chalks. The rocks yielded under increasing hydrostatic stress by pore collapse. The same effect was produced by holding a constant hydrostatic stress and reducing the pore pressure. This pore collapse reduced the permeability.

Plastic Bifurcation in the Triaxial Confining Pressure Test

Journal of Applied Mechanics, 2000
Bifurcations of a circular cylinder are studied, within the context of the triaxial confining pressure test, for pressure sensitive solids. Material response is modeled by large strain versions of flow and deformation theories of plasticity in conjunction with the Drucker-Prager solid.

Q Measurements under Confining Pressure

1979
Birch and Bancroft [1] demonstrated the feasibility of resonating a rock sample under hydrostatic pressure by vibrating the fully encapsulated samples in the torsional mode. They used this approach to obtain some Q data and extensive data on the modulus of rigidity as a function of pressure for a wide variety of rock samples.

Confinement of Photopolymerization and Solidification with Radiation Pressure

Journal of the American Chemical Society, 2011
Controlling chemical reactions within a small space is a significant issue in chemistry, and methods to induce reactions within a desired position have various potential applications. Here we demonstrate localized, efficient photopolymerization by radiation pressure.
