Abstract The hydromechanical behaviour of fractured coal is a complex function interaction between bulk and fracture deformation driven by fluid pressure external stress. Despite the research studies conducted to date, combined effect mineral content structure on sorptive remains unexplored. To study this effect, we performed series X-ray computed tomography (XRCT) imaging range specimens with ...

Humic substances, the dark-colored, natural organic polyelectrolytes that are found in practically all soils, sediments, and natural water, strongly interact with both inorganic and organic pollutants. Inorganic cationic species generally undergo complexation reactions with humic substances. The binding of cations, such as cupric ions, by humic substances often markedly reduces their toxicity t...

The basic principle of liquisolid systems formulation lies in the conversion of the drug in a liquid state into an apparently dry, free-flowing and readily compressible powder by its blending (or spraying) with specific carriers and coating materials. The selection of the most suitable carrier and coating material depends especially on their values of flowable liquid retention potential (Φ), wh...
