Perfluorinated and sulfonated proton exchange membranes: Effect of supercritical fluid processing on ion exchange capacity and proton conductivity
The present work has processed Nafion® and sulfonated polystyrene-isobutylenestyrene (SIBS) with supercritical fluid (SCF) carbon dioxide at a 40°C and 200 bar with the aid of ten co-solvents of different size and polarity. ...
Assessment of the stability and biological activity of our model proteins encapsulated in hydrogel membranes
Proteins are biological macromolecules which have a unique spatial conformation. This spatial conformation can be affected by extremes in pH, temperature, and organic solvents. Once this 3D spatial conformation is affected ...
Magnetorheology in rotating magnetic fields
We studied the flow of ferrofluid induced by rotating magnetic fileds. This flow was observed for first time in fi96F by Moskowitz and Rosensweig [App1. Ph4s. Gett., 10, pag. 3Ofi (fi96F)] and since then researchers has ...
Sonolysis of pharmaceutical and personal care products as an advanced oxidation process for the remediation treatment of wastewater effluents
Pharmaceutical and Personal Care Products (PPCPs) are a diverse group of chemicals, also known as xenobiotics, treated like potential environmental pollutants. Recently, PPCPs have been detected in trace amounts in surface ...
Novel separation methods for removing nanoparticles and copper from chemical mechanical planarization wastes
Chemical mechanical planarization (CMP) wastewater emanating from semiconductor processing contains copper (II) ions and either alumina and/or silica nanoparticles. The efficiency of biotreatment schemes to remove copper ...
