Siliceous ordered mesoporous materials (OMM) are gaining interest as supports for enzyme immobilization due to their uniform pore size, large surface area, tunable pore network and the introduction of organic components to mesoporous structure. We used SBA-15 type silica materials, which exhibit a regular 2D hexagonal packing of cylindrical mesopores of uniform size, for non-covalent immobiliza...

Earthworms affect macro-pore structure of soils. However, some studies suggest that earthworm burrow walls and casts themselves differ greatly in structure from surrounding soils, potentially creating habitat for microbivorours nematodes which accelerate the decomposition and C and N mineralization. In this study aggregates were sampled from the burrow walls of the anecic earthworm Lumbricus te...

Extremely low permeability due to nano-scale pores is a distinctive feature of gas transport in a shale matrix. The permeability of shale depends on pore pressure, porosity, pore throat size and gas type. The pore network model is a practical way to explain the macro flow behavior of porous media from a microscopic point of view. In this research, gas flow in a shale matrix is simulated using a...

Quantitatively characterizing the micro-scale heterogeneity of pore throats in tight sandstone reservoirs is key to accurately describing influence structures on fluid occurrence characteristics. In this study, taking Chang 6 Member Yanchang Formation Huaqing area Ordos Basin as an example, pore-throat and its state have been systematically studied using cast thin section, scanning electron mic...

Tillage practices can influence the pore size distribution (PSD) of soil, affecting soil physical and hydraulic properties as well processes that are essential for plant growth, hydrology, environmental studies modeling. A study was conducted to assess effect no-tillage (NT) conventional tillage (CT) on PSD derived from soil–water retention curves (SWRCs) using van Genuchten’s equation (vG) at ...

Recently, we have introduced a novel, material-independent processing method for producing macro porous ceramics with capillary suspensions as a stable precursor. A capillary suspension is a three-phase system where a small amount of an immiscible secondary liquid is added to a suspension resulting in the formation of a sample spanning particle network. This technology provides open porosities ...
