To improve the anti-biofouling properties of membranes, Ag-embedded nano-sized titanium dioxide (Ag-n-TiO2) particles were utilized as biocidal agents to modify polyvinyl chloride (PVC) membranes. Both Ag-n-TiO2/PVC flat sheet membranes and reinforced hollow fiber membranes were fabricated by a phase inversion method with varying Ag-n-TiO2 particle concentrations. As a result, the hydrophilicity, permeability, and retention capability increased with Ag-n-TiO2 concentrations from 0 to 1.5 wt%. In addition, the in situ antibacterial and anti-formation of biofilm properties of the modified membranes were greatly enhanced in the conventional inhibition zone test, Escherichia coli (E. coli) absorption experiment, fluorescent staining experiment, as well as long-term continuous biofouling test. The best results were obtained for the PVC membrane modified by 1.0 wt% Ag-n-TiO2. The optimized membrane presented not only better permeability and in situ antibacterial properties in the E. coli adhesion test, but also an enhancement in resisting biofilm formation and a more steady permeation flux in long-term filtration than the unmodified membrane. © The Royal Society of Chemistry 2015.

Mechanical processes used to make plastic pellets and transport them through manufacturing, shipping and end-use can create contaminant bodies. These bodies include normal polymer fines, high-melting polymer (angel hair, snake skins), surface applications like lubricants and waxes and oligomers. They cause various problems in material handling, processing and product performance. Analytical laboratory techniques can readily provide the identification needed to specify corrective actions. Examples from polyamide processing are discussed.

MoVTeNbO catalysts were characterized with XRD, XPS, and FTIR techniques and tested in the ammoxidation of propane. Bismuth-modified MoVTeNbO catalysts showed a higher acrylonitrile yield than the base four-component system. The effect of the reaction mixture composition (C3H8, NH3 and O2) on selectivity towards different products was studied at propane conversion above 80%. The favorable effect of bismuth promoter on the selectivity towards acrylonitrile was explained by suppression of acrylonitrile transformation connected with decreasing acidity of the catalyst. © 2015 Published by Elsevier B.V.
