The interfacial polymerization dynamics are tracked by successive droplet and capsule deformation using a straightforward microfl uidic approach. ab We use microfluidic polydimethylsiloxane (PDMS) devices to measure the kinetics of reactive encapsulations occurring at the interface of emulsion droplets. The formation of the polymeric shell is inferred from the droplet deformability measured in ...
Kinetic Study and Modelling of n-Heptane Reforming Process over Pt/Zr-HMS/HZSM-5 Composite Catalysts
Pt/Zr(x)-HMS/HZSM-5 catalysts with various Si/Zr ratios (as x) were used for investigation of the kinetics of n-heptane reforming process under 350 - 450 oC reaction temperature, 35 to 80 ml min-1 flowing rate of hydrogen and 2 to 5 ml h-1 flowing rate of n-heptane. In the present work, two kinetics (power law and Langmuir - Hinshelwood) models were selected and examined to describe the kinetic...
Background and purpose: Natural organic matter in water resources (mainly caused by humic acid) leads to formation of THMs and HAAs. Removal of DBPs precursors from drinking water resources is the most important step to prevent from THMs formation. The aim of this study was to investigate the efficiency of modified nanoclay with EDTA and fresh nanoclay in adsorption of humic acid in aquatic sol...
kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using redox initiators (tbhp/fe2+/edta/asac and tbhp/fe2+/edta/sfs) at relatively low temperatures and thermal initiators (bpo, kps and aibn) at higher temperatures to seek the most suitable initiator system. at the end of all reactions the unreacted monomer content was r...
