Ostreolysin, a pore-forming protein from the edible oyster mushroom (Pleurotus ostreatus), is a member of the aegerolysin protein family, a novel group of small acidic proteins found in bacteria, molds, mushrooms, and plants. It binds to lipid rafts and interacts specifically with cholesterol-rich lipid domains. In this study, ostreolysin was classified as a single-domain all-beta-structured pr...

A brief description is given of devolatilization of raw coal and combustion of the residual char. Major achievements in the study of devolatilization and important areas for further experimentation are noted; however, attention is focussed on the rate processes involved in char combustion. Means of calculating reaction rates are shown which account for temperatures of particles, mass transfer a...

In this paper, the pore structure characterization of concrete exposed to deionised water and 5% NaCl solution was evaluated using mercury intrusion porosity (MIP), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The effects of calcium leaching, fly ash incorporation, and chloride ions on the evolution of pore structure characteristics were investigated. The results demonstrate ...

Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure fluid flow of rocks time. This study presents experimental evidence to illustrate that evolves with sedimentation, carbonate cementation, clay growth, dissolution. It examines, describes characterizes a suite core samples from Gaotaizi oil layer second third members Qingshankou F...

Abstract Shale rocks are highly structurally and chemically heterogeneous, such that the pore structure–transport relationship is complex. Shales typically have porosity over many length-scales from molecular up to macroscopic fractures. This work utilizes gas overcondensation probe sizes micropores very large macropores all in same experiment without potential for damage due high pressures whe...

We study the structural and mechanical properties of nanoporous (NP) carbon materials by extensive atomistic machine-learning (ML) driven molecular dynamics (MD) simulations. To this end, we retrain a ML Gaussian approximation potential (GAP) for recalculating a-C database Deringer Csányi adding van der Waals interactions. Our GAP enables notable speedup improves accuracy energy force predictio...

The micropore structure’s permeability contribution to total of the heterogeneous reservoir with multiscale pore structures is critical for evaluation but still not well understood. This paper proposes a structure characterization method based on high-resolution SEM images quantitatively analyse structures’ content and their contributions via six steps. First, image-based rock typing implemente...

The pore structure of three-dimensional scaffolds used in tissue engineering has been shown to significantly influence cellular activity. As the optimal pore size is dependant on the specifics of the tissue engineering application, the ability to alter the pore size over a wide range is essential for a particular scaffold to be suitable for multiple applications. With this in mind, the aim of t...
