The rotational tunneling and librational excitations of the one-dimensional quantum rotor, methyl iodide, confined in porous glass monoliths ~mean pore diameter of 58 Å! have been investigated using incoherent inelastic neutron scattering. When the pores are completely filled with the solid at low temperatures (5 K ,T,35 K), the system exhibits a tunneling spectrum composed of two sets of inela...

This paper studies axially symmetric vibrations of a liquid-filled poroelastic thin cylinder saturated with two immiscible liquids of infinite extent that is surrounded by an inviscid elastic liquid. By considering the stress free boundaries, the frequency equation is obtained. Particular case, namely, liquid-filled poroelastic cylinder saturated with single liquid is discussed.  When the waven...

Confinement effects on protein stability are relevant in a number of biological applications ranging from encapsulation in the cylindrical cavity of a chaperonin, translocation through pores, and structure formation in the exit tunnel of the ribosome. Consequently, free energies of interaction between amino acid side chains in restricted spaces can provide insights into factors that control pro...

Molecular dynamics simulations of water in cylindrical hydrophilic pores with diameters of 1.5 and 3 nm were performed to explore the phase behavior and the nucleation dynamics of the confined fluid as a function of the percentage of volume filled f. The interactions of water with the pore wall were considered to be identical to the interactions between water molecules. At low water contents, a...

Abstract Emission of nitrous oxide (N 2 O) from peatlands contributes very significantly to the world global warming, although factors controlling N O emissions are not yet clear. This study aimed determine peat characteristics in peatlands. and several soil (pH, electrical conductivity, height water table, water-filled pore space, decomposition degree peats, bulk density, organic carbon, total...

Inclusion-based formulations allow an explicit description of pore geometry by viewing porous rocks as a solid matrix with embedded inclusions representing individual pores. The assumption commonly used in these formulations that there is no fluid pressure communication between pores is reasonable for liquid-filled rocks measured at high frequencies; however, complete fluid pressure communicati...
