We report for the first time on pore-suspending lipid bilayers, which we call micro-black lipid membranes (micro-BLMs), based on a highly ordered macroporous silicon array. Micro-BLMs were established by first functionalizing the backside porous silicon surface with gold and then chemisorbing 1,2-dipalmitoyl-sn-glycero-3-phosphothioethanol followed by spreading 1,2-diphytanoyl-sn-glycero-3-phos...

The aim of this work is to better understand fluid displacement mechanisms at the pore scale in relation to capillary-filling rules. Using specifically designed micro-models we investigate the role of pore body shape on fluid displacement during drainage and imbibition via quasi-static and spontaneous experiments at ambient conditions. The experimental results are directly compared to lattice B...

The paper presents two-scale numerical algorithms for stress–strain analysis of porous media featured by self-contact at pore level. porosity is constituted as a periodic lattice generated representative cell consisting elastic skeleton and void pore. Unilateral frictionless contact considered between opposing surfaces the For homogenized model derived in our previous work, we justify increment...

BACKGROUND In geochemically perturbed systems where porewater and mineral assemblages are unequilibrated the processes of mineral precipitation and dissolution may change important transport properties such as porosity and pore diffusion coefficients. These reactions might alter the sealing capabilities of the rock by complete pore-scale precipitation (cementation) of the system or by opening n...

In the last few decades, micro-models have become popular experimental tools for two-phase flow studies. In this work, the design and fabrication of an innovative, elongated, glass-etched micro-model with dimensions of 5 × 35 mm(2) and constant depth of 43 microns is described. This is the first time that a micro-model with such depth and dimensions has been etched in glass by using a dry etchi...

Due to the peculiarity of spring domain strata in Jinan, phenomenon serious water seepage appears process excavation. The macro permeability soil is closely correlated with its microstructure. In this study, using X-ray micro-tomography (micro-CT) system and a self-designed device, internal pore structure Jinan red clay flow inside sample under different stages were observed. microstructure pha...

development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. in this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. afterw...
