Polyelectrolyte conditioning of ferric sulfate sludge
… of the testing was to determine if cationic, anionic and nonionic polyelectrolytes could successfully condition the sludge to improve its dewaterability. In addition the parameters which affected the conditioning mechanism. were investigated. Tests that were run during the investigation …

Synthesis and Solution Properties of Semi-rigid Polyelectrolytes and Polyampholytes
… polymers. Using a deprotection strategy, anionic polyelectrolytes and polyampholytes of stilbene-maleic anhydride copolymers were synthesized and characterized by first synthesizing organic-soluble polymer precursors. Solution shear rheology and statistical segment length measurements …

An evaluation of polyelectrolytes in the chemical treatment of textile mill wastes
… to ascertain whether chemical treatment with polyelectrolytes could achieve an economical treatment. The study consisted of the evaluation of flocculation performance (turbidity, chemical oxygen demand, and color reductions) for treatments with alum alone and alum with polyelectrolytes. A …

Hybrid nanolayer architectures for ultrafast acousto-plasmonics in soft matter
… were built via layer-by-layer deposition. Anionic polyelectrolytes with Azobenzene side groups (PAzo) were alternated with cationic polymer PAH, for the creation of transducer films. PSS/PAH multilayer were built for spacer layers, which do not absorb in the visible light range. The …
