To attempt a new approach to improve the grinding of cassiterite–polymetallic sulfide ores while simultaneously reducing cassiterite overgrinding and undergrinding, this article looked into effects chemical additives on distribution product size. Six chemicals, namely sodium hexametaphosphate, triethanolamine, ferric sulphate, aluminum chloride, polyaluminum chloride polyacrylamide, were compar...

The paper is focused on the formation of calcium phosphate nanoparticles (CP) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, anionic surfactantant and cosurfactant, in the presence of anionic and cationic polyelectrolyte. It is shown that polyelectrolyte, can be incorporated into the individual inverse microemulsion droplets. The ...

An electrochemical theory of the glycocalyx surface layer on capillary endothelial cells is developed as a model to study the electrochemical dynamics of anionic molecular transport within capillaries. Combining a constitutive relationship for electrochemical transport, derived from Fick's and Ohm's laws, with the conservation of mass and Gauss's law from electrostatics, a system of three nonli...

Excessive water production impacts the economics of petroleum reservoir and often leads to their premature shut-in. Production high saline represents a major corrosion for casing, tubing, flow lines, facilities. Polymer solution has been used control plug in high-temperature reservoirs. Most these polymer solutions consist polyacrylamide-based an organic or inorganic cross linker. Polyethylene m...
