Interaction of Mucins with Proteins and Polymers and Its Influence on the Interfacial Lubricity
In this study, we present the interaction of mucins with proteins or polymers and its impact on the conformation, surface adsorption, and lubrication properties at a self-mated sliding contact of poly(dimethylsiloxane) (PDMS) in aqueous solutions. Due to its unique amphiphilicity, mucins are known to spontaneously adsorb onto hydrophobic surfaces and possibly lubricate them in aqueous environme...
متن کاملApplication of synthetic polymers as adsorbents for the removal of cadmium from aqueous solutions: Batch experimental studies
In the present study seven synthetic polymers were used as adsorbents for the removal of Cd(II) from aqueous solution. The equilibrium studies were systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. The analyzing system was an atomic absorption spectrometer (Perkin-Analyst 100). It was...
متن کاملCiliary propulsion of objects in tubes: wall drag on swimming Tetrahymena (Ciliata) in the presence of mucin and other long-chain polymers.
The lubrication effect of three long-chain polymers - mucin, methylcellulose and Ficoll - on ciliary propulsion in tubes is measured by plotting the relative velocities of swimming cilitates as a function of the tube bore diameter. Mucin shows the most unequivocal lubrication, which is found at concentrations between 0% and 9.1% (w/v). This observation, coupled with viscometric measurements whi...
متن کاملBatch experimental studies of Hg(II) ion removal from aqueous solution using seven synthetic polymers
In this work application of seven synthetic polymers as adsorbents for the removal of Hg(II) from aqueous solution was studied. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Variations of Hg(II) concentration in solution have been studied through measur...
متن کاملBoundary Lubrication of PEO-PPO-PEO Triblock Copolymer Physisorbed on Polypropylene, Polyethylene, and Cellulose Surfaces
In situ lateral force microscopy (LFM) and X-ray photoelectron spectroscopy (XPS) were used to probe the lubrication behavior of an aqueous solution of poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) (PEO-PPO-PEO) symmetric triblock copolymer on thin films of polypropylene (PP), polyethylene (PE), and cellulose. LFM experiments were carried out while the substrates were immersed in water...
