"Increasing surface hydrophilicity with biopolymers: a combined single " by Piotr Pawliszak, Amir Beheshti et al.
Hypothesis: Naturally extracted polysaccharides, such as guar gum, are promising candidates for environmentally friendly flotation reagents. It is hypothesized that the kinetics of collision of sub- to millimeter gas bubbles with a hydrophobic graphite surface, and the stability of thin liquid film formed between the bubble and surface is affected by an adsorbed layer of guar gum. Experiments: A combination of gravimetric (quartz crystal microbalance with dissipation) and imaging (atomic force m...
