Mechanical characteristics of organically modified fly ash-kaolinite mixtures
… class F fly ash in geotechnical engineering, biopolymers (Chitosan, and Xanthan gum) and synthetic polymers (Polyethylene Oxide, PEO) were used instead of the traditional stabilizers to improve the engineering behaviors of fly ash-kaolinite mixtures. The effects of polymers on microstructure …

Statistical mechanical theory of structure and miscibility of polymer nanocomposites: Effects of density, filler shape, and chemical heterogeneity
… types of nanoparticles or fillers added to polymers to enhance the material properties, the Polymer Reference Site Interaction Model (PRISM) theory is applied to study the structure and miscibility of polymer nanocomposites (PNCs). Spherical fillers are studied in homopolymers of varying …

The effect of flotation reagents on the coagulation and dewatering of flotation tailings
… (e.g., polyacrylamides), that work through polymer bridging or patch processes. Systems which comprise flocculants or coagulants demonstrated higher settling rates, achieving turbidity reductions beyond 500 NTU/min within the initial five minutes, significantly exceeding the performance of …

An investigation into the impact of residual reagents on flotation in response to process water recirculation
… two mechanisms by which flocculation occurs: the polymer bridging theory and the patch model. Polyacrylamides (PAM) are the most common flocculants. Coagulants use a charge neutralisation mechanism to take effect with the most common type being used are salts containing highly charged cations such …
