Chapter 1 Poromechanics of saturated isotropic nanoporous materials
1.1 Abstract Poromechanics offers a consistent theoretical framework for describing the mechanical response of porous solids. When dealing with fully saturated nanoporous materials, which exhibit pores of the nanometer size, additional effects due to adsorption and confinement of the fluid molecules in the smallest pores must be accounted for. From the mechanical point of view, these phenomena ...
متن کاملRevisiting poromechanics in the context of microporous materials
Poromechanics offers a consistent theoretical framework for describing the mechanical response of porous solids fully or partially saturated with a fluid phase. When dealing with fully saturated microporous materials, which exhibit pores of the nanometer size, aside from the fluid pressure acting on the pore walls additional effects due to adsorption and confinement of the fluid molecules in th...
متن کاملNanoporous structures: smaller is stronger.
Nanoporous structures have become the focus of intensive research in recent years owing to their unique applications in mesoscopic physics and chemistry, and potential technological applications, including sensing, catalysis, DNA translocation, and as templates for nanostructure self-assembly. The study of nanoporous structures such as nanopore-, nanocavity-, and nanochannel-array materials can...
متن کاملEnhanced PEC performance of nanoporous Si photoelectrodes by covering HfO2 and TiO2 passivation layers
Nanostructured Si as the high efficiency photoelectrode material is hard to keep stable in aqueous for water splitting. Capping a passivation layer on the surface of Si is an effective way of protecting from oxidation. However, it is still not clear in the different mechanisms and effects between insulating oxide materials and oxide semiconductor materials as passivation layers. Here, we compar...
متن کاملConsolidation Around a Heat Source in an Isotropic Fully Saturated Rock with Porous Structure in Quasi-Static State
The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...
